Building Xen 3.4.1 Dom0 via xenified 2.6.30.1 kernel on top Ubuntu 9.04 Server

To build xenified 2.6.30.1 via Andrew Lyon’s 2.6.30 patch set in it’s current state downloaded patch set. Per Jan Beulich:-
The fix is to change the dependency from CONFIG_SPARSE_IRQ to CONFIG_GENERIC_HARDIRQS in the 2.6.30 patch.View [2].
**********************
Update on 07/10/09
**********************
The schema bellow has been tested positive on Core2Duo E8400, E6600,Q9550 boxes. Building kernel without changing dependency with CONFIG_SPARSE_IRQ=y in .config file also allows to load kernel under Xen 3.4.1. Regarding the most recent pvops enabled kernel view 2.6.31-rc1.

# wget http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.30-2.tar.bz2
# tar jxvf xen-patches-2.6.30-2.tar.bz2
#cd xen-patches-2.6.30-2

1.Captured log1 via script

rm -f log1
touch -f log1
for V in `ls 6*`
do
echo $V >> log1
cat $V|grep CONFIG_SPARSE_IRQ >> log1
done

2. Analyzed log1

4.Untared linux-2.6.30.1.tar.bz2 and applied patches.
Built kernel :-

# make menuconfig







# make
# make modules_install install
# mkinitramfs -o /boot/initrd-2.6.30.1.img 2.6.30.1

To test 2.6.30.1 xenified kernel setup Xen 3.4.1 on to top of Ubuntu Jaunty Server. First – install on Uubuntu 9.04 Server all packages required for Xen build:-

apt-get install libcurl4-openssl-dev \
xserver-xorg-dev \
python2.6-dev \
mercurial gitk \
build-essential \
libncurses5-dev \
uuid-dev gawk \
gettext texinfo bcc

Second – build Xen from source

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
# cd xen-3.4-testing.hg
Set in Config.mk
PYTHON = python
PYTHON_PREFIX_ARG =
# make install-xen
# make install-tools
# make install-stubdom

Tuning Config.mk results Xen packages to be placed into /usr/local/lib/python2.6/dist-packages due to Changeset 19594 in xen-3.4-testing.hg. Otherwise, Xen packages would go to /usr/lib/python2.6/site-packages, which is not default location for python 2.6 on Ubuntu 9.04 ( vs F11 ). Thus you won’t be able to start xend in Dom0. Same thing happens when building Xen Unstable on Ubuntu 9.04 Server.
Add entry to /boot/grub/menu.lst:-

title Xen 3.4 / Ubuntu 9.04 kernel 2.6.30.1
uuid 34d2c0bd-fe30-47e0-990e-4921caf1e845
kernel /boot/xen-3.4.gz
module /boot/vmlinuz-2.6.30.1 root=/dev/sda14 ro console=tty0
module /boot/initrd-2.6.30.1.img

and rebooted into xen host.Tested OSOL 2009.06 loaded with PV Drivers in HVM and STUB domains OK , also tested OSOL 2009.06 PV DomU ,F11 PV DomU, Ubuntu Jaunty HVM and PV DomUs sharing same image device.

2.2.6.30 dom0 Xen patches

Setup Xen 3.4.1 Dom0 on top of Ubuntu 9.04 Server via Marc – A. Dahlhaus’s UDEV patch

Per Marc – A. Dahlhaus:-
Udev removed the udevinfo symlink from versions higher than 123 and xens build-system could not detect if udev is in place and has the required version. In particular, Ubuntu 9.04 server has udev version
141 and appears to be affected by this issue. Straight forward Xen 3.4.1 build brings up Xen Host with hotplug scripts rejecting to work.
The recent patch suggested by Marc resolves this problem. It doesn’t
happen on F11 due to

[root@ServerXen341 /]# ls -l /usr/bin/udevinfo
lrwxrwxrwx. 1 root root 18 2009-06-12 14:13 /usr/bin/udevinfo -> ../../sbin/udevadm
[root@ServerXen341 /]# /usr/bin/udevinfo -V
the program '/bin/bash' called '/usr/bin/udevinfo', it should use 'udevadm info ', this will stop working in a future release
141

Brief description of Xen 3.4.1 build follows bellow. First – install on Uubuntu 9.04 Server all packages required for Xen build:-

apt-get install libcurl4-openssl-dev \
xserver-xorg-dev \
python2.6-dev \
mercurial gitk \
build-essential \
libncurses5-dev \
uuid-dev gawk \
gettext texinfo bcc

Second step :-

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
# cd xen-3.4-testing.hg
Set in Config.mk
PYTHON = python
PYTHON_PREFIX_ARG =

Tuning Config.mk results Xen packages to be placed into /usr/local/lib/python2.6/dist-packages due to Changeset 19594 in xen-3.4-testing.hg. Otherwise, Xen packages would go to /usr/lib/python2.6/site-packages, which is not default location for python 2.6 on Ubuntu 9.04 ( vs F11 ). Thus you won’t be able to start xend in Dom0. Same thing happens when building Xen Unstable on Ubuntu 9.04 Server.

Setup Fedora 11 PV DomU at Xen 3.4.1 Dom0 (kernel 2.6.30-rc6-tip) on top of Fedora 11

The most impressive F11 Xen related features seem to be the nice Xen 3.4.1 build with python 2.6 coming as default with F11 and graphical installer behavior during pygrub based PV DomU installation phase. F11 is supposed to be installed without libvirt to avoid conflict during Xen 3.4.1 port to Fedora 11 instance. Xen 3.3.1 Hypervisor working with libvirt may be installed on F11 via xen-3.3.1-11.fc11.src.rpm. Notice, that mentioned version of Xen 3.3.1 is already patched to work with pvops kernels and may be also patched for pygrub ZFS support. View [1] for details . As appears setting default path for python packages to /usr/lib/python2.6/site-packages resolves issues with Xen build raising up on Ubuntu 9.04 Server (/usr/local/lib/python2.6/dist-packages).

module /boot/vmlinuz-2.6.30-rc6-tip root=/dev/mapper/vg_fedora11-LogVol00 ro console=tty0
module /boot/initrd-2.6.30-rc6-tip.img

Set initdefault to 3 in /etc/inittab and reboot in Xen environment,
having /etc/rc.local to start:-

export HOME=/root
vncserver :1 -geometry 1280x1024 -depth 16
/etc/init.d/xend start
/etc/init.d/xendomains start

Xend and xendomains would be better to setup running as services :-

# chkconfig xend on
# chkconfig xendomains on

View also :-
Remote Login with GDM and VNC on Fedora 11 regarding standard setup resumable VNC session. It seemed to me too much unstable. Several actions required root authorization caused VNC session to interrupt.

Connect to Xen Host remotely via vncviewer



Bring up local Apache Server to create HTTP installation source.

# chkconfig httpd on
# service httpd start
# mount -o loop f11.iso /var/www/html/f11
# wget http://192.168.1.36/f11/images/pxeboot/vmlinuz
# wget http://192.168.1.36/f11/images/pxeboot/initrd.img

Create installation profile:-

ramdisk = "/home/boris/fedora/initrd.img"
vcpus=2
on_reboot = 'restart'
on_crash = 'restart'

# xm create f11.install
# vncviewer localhost:0

This time graphical installer will be brought up with no issues (vs F10). Been prompted by installer about source : choose URL and submit http://IP-Dom0/f11

1. Backport ZFS support to Xen 3.3.1 F10 Dom0 (kernel 2.6.30-rc3-tip)

Backport ZFS Support for pygrub to Xen 3.3.1 providing via http://gitco.de

Gitco is providing http://www.gitco.de/repo/src/xen-3.3.1-0.src.rpm for free download. It gives an immediate option to back port Pygrub ZFS support from Xen 3.4-testing mercurial tree. Raw content of CSs 19322,19323 is supposed to be placed into patch files under /usr/src/redhat/SOURCES.
File /usr/src/redhat/SPECS/xen-3.3.1.spec gets updated to process two more patches added to SOURCES. The last step is to run rpmbuild to create RPMS with patches to be installed instead of original ones from http://gitco.de. Details follow bellow:-

Light weight X-windows System for Xen 3.5-Unstable Dom0 on top of Ubuntu 9.04 Server

Management remote Xen Unstable Dom0 on top of Ubuntu Jaunty Server via VNC connection,invoking /usr/bin/gnome-session might have a problem with low quality network switches, unable properly communicate with PCI-E Ethernet Gigabit Adapters integrated on the boards.Light weight X environment might be required to manage HVM DomUs via VNC. Following bellow is an exact set of instructions for Xen 3.5(4) hackery on Ubuntu 9.04 Server. AppArmor and Network-Manager may be kept as installed originally . View [1] for the first draft.
Have Ubuntu Intrepid Server dual boot with Jaunty just to perform Xen build properly and remove afterwards . It’s needed due to issues with python setup on Jaunty Server. We would build Xen Unstable (3.5) from source on Ubuntu 8.10 server and perform install via “make dist and install.sh to remote instance”. I believe procedure bellow will run same way with Jaunty root file system mounted as NFS share on Intrepid Server.
Follow [2] and install Light weight X windows system. Instructions bellow are a bit different from [2]. That was
the way it worked for me. I’ve installed synaptic right away to get eterm&gsetroot installed. Synaptic is also very helpful when install packages for Xen build. Install GUI and VNC:-
Downsize the system:
vi /etc/default/linux-restricted-modules-common:
DISABLED_MODULES=”ath_hal fc fglrx ltm nv”

Install the X11 bare bone:
# aptitude install x-window-system-core
# aptitude install fluxbox fluxconf #lightwight windows manager
# aptitude install dillo #lightweight browser
# aptitude install xfe #lightweight file manager
# apttitude install synaptic # To install eset & esetroot
Change /etc/X11/xorg.conf:
# dpkg-reconfigure xserver-xorg #guided setup
Edit /etc/X11/xorg.conf (use “gtf 1024 768 60″ to obtain the Modeline values)
When done start X-server to make sure fluxbox is completely functional :-
startx

Notice , that x11vnc would work , but not under Xen Hypervisor. So, installed via Synaptic all SDL libraries and vnc4server. Updated ~.vnc/xstartup to start fluxbox in background. Updated /etc/rc.local :-
vncserver :1 -geometry 1280×1024 -depth 16
Perform core build on Ubuntu Intrepid Server.

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-unstable.hg
# cd xen-unstable.hg
# make world
# make dist

Second – install on Uubuntu 9.04 Server all packages required for Xen build:-

libcurl4-openssl-dev
xserver-xorg-dev
python2.6-dev
python2.5
python2.5-dev
mercurial
gitk
build-essential
libncurses5-dev
uuid-dev
gawk
gettext
texinfo
bcc

and perform fake Xen Unstable build on Ubuntu Jaunty Server :-

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-unstable.hg
# cd xen-unstable.hg
Set in Config.mk
PYTHON = python
PYTHON_PREFIX_ARG =
# make install-xen
# make install-tools
Remove installed Hypervisor and tools
# make uninstall

This actions will result Xen packages to be installed in :-
/usr/local/lib/python2.6/dist-packages/xen# ls -l

At this point you would have to install either xenified 2.6.29.4 or pvops enabled kernel on Ubuntu 9.04 (aka Jaunty )Server. I’ve tested 2.6.29.4 ,patched via rebased Suse’s rpm by Andy Lyon, and the most recent 2.6.30-rc6-tip kernels.
How to install pvops enabled kernel from Jeremy Fitzhradinge
git repository:-

Checkout the most recent branch:-
# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
# cd linux-2.6-xen
# git checkout origin/xen-tip/next -b xen-tip/next

# make menuconfig
Now build
# make
# make modules_install install
# mkinitramfs -o /boot/initrd-2.6.30-rc6-tip.img 2.6.30-rc6-tip

Add entry to /boot/grub/menu.lst:-

Install Ubuntu Jaunty PV & HVM DomUs at Xen 3.4 Dom0 (kernel 2.6.30-rc6-tip) sharing the same image

The most recent 2.6.30-rc6-tip pvops enabled kernel now supports HVM DomUs, what allows to reproduce, known for xenified kernel’s Dom0s, approach for building Intrepid and Jaunty Server PV DomUs via previously created HVM images to avoid traditional but a bit complicated debootstrap procedure. CentOS 5.3, Ubuntu Jaunty Server ,Solaris 10U6 (64-bit) HVMs have been successfully tested after the most recent kernel upgrade. Create HVM DomU via profile:-

name = "JauntyHVM"
builder = "hvm"
memory = "1024"
disk = ['phy:/dev/loop0,hdc:cdrom,r','phy:/dev/sdb12,hda,w']
# disk = ['phy:/dev/sdb12,hda,w']
vif = [ 'type=ioemu,bridge=eth0' ]
device_model = "/usr/lib64/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
vnc=1
boot="d"
usb=1
usbdevice="tablet"
vcpus=1
on_reboot = "restart"
on_crash = "restart"

Load PV DomU via profile with VFB to add grub entry for serial PV DomU console:-

memory = 2048
name = "Ubuntu9.04PV"
vcpus = 1
vif = [ 'bridge=eth0' ]
disk = [ 'phy:/dev/sdb12,xvda,w']
vfb= ['type=vnc,vncunused=1']

To enable serial console add grub entry:-

title Ubuntu 9.04 (hvc0) , kernel 2.6.28-11-server
kernel /boot/vmlinuz-2.6.28-11-server root=/dev/xvda1 ro console=hvc0
initrd /boot/initrd.img-2.6.28-11-server

Copy /etc/event.d/tty1 to /etc/event.d/hvc0
Next modify /etc/event.d/hvc0 as follows

# cat /etc/event.d/tty1
# tty1 – getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.

start on stopped rc2
start on stopped rc3
start on stopped rc4
start on stopped rc5

stop on runlevel 0
stop on runlevel 1
stop on runlevel 6

respawn
exec /sbin/getty 38400 hvc0

Shutdown DomU. Now load PV DomU via serial console:-

memory = 2048
name = "Ubuntu9.04PV"
vcpus = 1
vif = [ 'bridge=eth0' ]
disk = [ 'phy:/dev/sdb12,xvda,w']

Run tasksel to install Ubuntu Desktop for PV DomU.
Shutdown PV DomU and load HVM DomU.
Ethernet interface at HVM DomU should now be up and running
with IP obtained via DHCP

Deployment Xen 3.4 (testing) with 2.6.30-rc5-tip kernel to Ubuntu 9.04 Server (64-bit)

Have Ubuntu Intrepid Server dual boot with Jaunty just to perform Xen build properly and remove afterwards . It’s needed due to issues with python setup on Jaunty Server. We would build Xen 3.4 from source on Ubuntu 8.10 server and perform install via “make dist and install.sh to remote instance”. I believe procedure bellow will run same way with Jaunty root file system mounted as NFS share on Intrepid Server.
First – perform core build on Ubuntu Intrepid Server.

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
# cd xen-3.4-testing.hg
# make world
# make dist

**************************************************************************
Update on 05/22/09.
The most recent kernel 2.6.30-rc6-tip appears to work fine on this Xen port to Jaunty and supports HVM as expected
**************************************************************************
Second – install on Jaunty Server all packages required for Xen build and perform fake Xen 3.4 build on Ubuntu Jaunty Server :-

# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
# cd xen-3.4-testing.hg
Set in Config.mk
PYTHON = python
PYTHON_PREFIX_ARG =
# make install-xen
# make install-tools
Remove installed Hypervisor and tools
# make uninstall

This actions will result Xen packages to be installed in :-
/usr/local/lib/python2.6/dist-packages/xen# ls -l

module /boot/vmlinuz-2.6.30-rc5-tip root=/dev/sda1 ro console=tty0
module /boot/initrd-2.6.30-rc5-tip.img

At this point you would have to install either xenified [1] or pvops enabled kernel [2] on Ubuntu Jaunty Server. I’ve tested Suse’s 2.6.27.5 and the most recent 2.6.30-rc5-tip kernels. Both works fine. Dmesg report for 2.6.30-rc3-tip kernel :-

If you prefer to port via xensource.org Suse’s xenified kernel it will reproduce results from [1] with the most recent Xen Hypervisor 3.4 and 2.6.27.5 xenified kernel from Novell on Ubuntu 9.04 Server.
Also activate classic VNC [3] to connect remotely to Ubuntu Jaunty Server . I’ve performed two more steps ( not sure they are required ). First:-

# apt-get remove network-manager
# /etc/init.d/networking restart

Second :-

# /etc/init.d/apparmor stop
# update-rc.d -f apparmor remove
# aptitude remove apparmor apparmor-utils
# reboot

Testing screen shots follow bellow:-

Backport ZFS support to Xen 3.3.1 F10 Dom0 (kernel 2.6.30-rc3-tip)

Fedora 11 Xen hypervisor package contains pv_ops dom0 kernel support, ie. it is able to boot bzImage format dom0 kernels, and pv_ops sysfs memory ballooning support is included as well. These features/patches are backported from Xen 3.4 development/unstable version to Fedora’s Xen 3.3.x.
Our current target is to add two more change sets from Xen Unstable as patches to F11 xen-3.3.1-11.fc11.src.rpm to provide Xen 3.3.1 Dom0 support for OpenSolaris and Nevada PV Guests with images utilizing the most recent Sun ZFS.Actually, we need following CS (19323,19322) to be backported to Xen 3.3.1:-

xen-backport-hg19322.patch (pygrub: Workaround for Solaris CR 1143256)
xen-backport-hg19323.patch (libfsimage: Support for zfs version 14.)

Xen-3.3.1-11.fc11.src.rpm may be rebuilt on F10 with the most recent F10’s updates installed. Obtained set of RPMS allow to install Xen 3.3.1 Hypervisor on F10,having same features as on F11. Corresponding xen’s backport patches contain raw data from change sets should be placed in /root/rpmbuild/SOURCES and /root/rpmbuild/SPECS/xen.spec file has to be modified accordingly to process this patches. Now proceed as follows:-

# yum update
yum install transfig texi2html libaio-devel dev86 glibc-devel.i386
# rpm -iv xen-3.3.1-11.fc11.src.rpm

Make changes as mentioned above.

# cd /root/rpmbuild/SPECS
# rpmbuild -ba ./xen.spec
# cd ../RPMS/x86_64
# yum install xen-debuginfo-3.3.1-11.fc10.x86_64.rpm \
xen-devel-3.3.1-11.fc10.x86_64.rpm \
xen-hypervisor-3.3.1-11.fc10.x86_64.rpm \
xen-libs-3.3.1-11.fc10.x86_64.rpm \
xen-runtime-3.3.1-11.fc10.x86_64.rpm \
xen-3.3.1-11.fc10.x86_64.rpm

Now install libvirt packages required :-

# yum install libvirt libvirt-python python-virtinst \
virt-manager virt-viewer

Build the most recent pvops enabled kernel:-

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
# cd linux-2.6-xen
# git checkout origin/xen-tip/next -b xen-tip/next

Tune kernel to support Xen in Dom0 ([1])

# make menuconfig
# make
# make modules_install install

Create a grub entry:-

title Xen 3.3.1 Fedora 10 (2.6.30-rc3-tip)
root (hd0,4)
kernel /xen-3.3.gz
module /vmlinuz-2.6.30-rc3-tip ro root=/dev/VolGroup01/LogVol00 console=tty0
module /initrd-2.6.30-rc3-tip.img

Edit /etc/inittab :

id:3:initdefault:

Enable services xend,xenconsoled,xenstored,libvirtd
and reboot into Xen Host.

Debootstrap Ubuntu Jaunty PV DomU at Xen 3.3.1 F10 Dom0 ( kernel 2.6.30-rc3-tip)

Fedora 11 Xen hypervisor package contains pv_ops dom0 kernel support, ie. it is able to boot bzImage format dom0 kernels, and pv_ops sysfs memory ballooning support is included as well. These features/patches are backported from Xen 3.4 development/unstable version to Fedora’s Xen 3.3.1. Xen-3.3.1-11.fc11.src.rpm may be rebuilt on F10 with the most recent updates installed. Obtained set of RPMS allow to install Xen 3.3.1 Hypervisor on F10,having same features as on F11, what is actually already done by Michael Young and Pasi Kärkkäinen. However,following bellow is step by step instruction for performing backport to F10 via F11’s source rpm. Another target of posting bellow is install F10 debootstrap RPM , what allows straight
forward PV DomU install for Ubuntu Jaunty,Intrepid,Hardy Guests at Xen 3.3.1 F10 Dom0 based on the most recent pv_ops enabled kernel 2.6.30-rc3-tip obtained via Jeremy Fitzhardinge git repository.
Virtualization group shouldn’t be selected during initial install, otherwise you would have:-

# yum remove xen-libs-3.3.0-1.fc10.x86_64

to install newly rebuilt packages, what will also remove all libvirt dependent packages from the system. All of them might be installed after xen packages via command:-

# yum install libvirt libvirt-python python-virtinst \
virt-manager virt-viewer

Thanks to Michael Young for support when doing this backport :-

# yum update
# yum install transfig texi2html libaio-devel dev86 \
glibc-devel.i386
# rpmbuild --rebuild xen-3.3.1-11.fc11.src.rpm

Getting stubdom to work on Xen 3.3 port via http://www.gitco.de/repo/xen3.3.0 to CentOS 5.2

Created in /etc/xen files:-

[root@ServerCentOS52 xen]# cat WinXPhvm-stubdom
kernel = “/usr/lib/xen/boot/hvmloader”
builder=’hvm’
memory = 512
name = “WinXPhvm”
vif = [ 'type=ioemu, bridge=eth0' ]
device_model = ‘/usr/lib/xen/bin/stubdom-dm’
boot=”d”
sdl=0
opengl=0
vnc=0
stdvga=0

[root@ServerCentOS52 xen]# cat WinXPhvm-dm
kernel = “/usr/lib/xen/boot/ioemu-stubdom.gz”
vif = [ ' ', 'bridge=eth0']
vfb = [ 'type=sdl' ]
# vfb = [ 'type=vnc' ]
disk = ['file:/etc/xen/isos/winxp.iso,hdc:cdrom,r','file:/etc/xen/images/disk.img,hda,w','file:/tmp/test,hdb,r']

Per Xen 3.3 Stubdom Release Notes run:-
# mkdir -p /exports/usr/share/xen/qemu
# ln -s /usr/share/xen/qemu/keymaps /exports/usr/share/xen/qemu
#  mkdir -p /exports/var/lib
#  ln -s /var/lib/xen /exports/var/lib
# /usr/sbin/fs-backend &

Switch from console to another terminal session :-

# xm create WinXPhvm-stubdom

In original hvm profile both vnc and sdl are disabled.
Selection is made *-dm Domain’s profile. Both option “sdl” or “vnc” work with the same performance.
However, vnc connection is preferable from my standpoint. Mouse just gets lost with SDL in final phase.
Second option requires connection to Vncserver at Dom0 :-
# vncviewer localhost:0
after “xm create WinXPhvm-stubdom”.
In both cases install goes hardly alive with long outages , looks like it gets stuck from time to time.
I’ve also added to runtime profile:-
usb=1
usbdevice=”tablet”
to improve mouse behavior in VNC session. It works as usual. I’ve also set up mem_dom0 to 4GB on 8GB box, but
WinXPhvm-dm allocated only 32 MB, no matter of mem_dom0’s size. I would guess bad Xen Hypervisor tuning on Dom0 due to limited experience from my side. Otherwise, performance is significantly worse then in usual HVM DomU. Same install for CentOS 5.2(1) just hangs on the third page “Keyboard Layout Selection”,
Solaris Nevada Build 98 generates following error at startup:-
Configuring /dev
ata_command: BSY too long!DRDY 0×1 CMD 0xe0 F 0×0 N 0×0 S 0×0 H 0×0 CL 0×0 CH 0×0
and obviously exists after configuration phase with message :-
No hard disk found

I was also able successfully and fast install in stub domains F8,F9,openSUSE 11,Ubuntu 8.04.1 Desktop
and Solaris 10 (05/08). For CentOS 5.2 (1) installer hangs at third page “Keyboard layout selection” and never comes back to live. Monitoring “xm list” i was waiting for a while, it looked like CPU resource had been taken by stub domain.
All mentioned Linux distros are 64-bit.

What’s amazing it’s installation and runtime performance Solaris 10 (05/08) (32-bit) in stubdom vs Windows XP.
I would expect some old fashioned IDE emulation providing by /usr/lib/xen/bin/stubdom-dm , not understandable
by Solaris Nevada 98. Boot up / Shutdown speed of S10 in stubdom seems to be very fast ( just close to HVM DomU)

[root@ServerCentOS52 xen]# cat s10hvm-stubdom
kernel = “/usr/lib/xen/boot/hvmloader”
builder=’hvm’
memory = 1024
name = “s10hvm”
vif = [ 'type=ioemu, bridge=eth0' ]
device_model = ‘/usr/lib/xen/bin/stubdom-dm’

OpenSUSE 11 snapshots :-

Ubuntu 8.04.1 & Debian Etch R2 in Stub Domains at Xen 3.3 CentOS 5.2 Dom0 (all 64-bit)

Debian Etch install took about 2 hr on the box with C2D E8400, 8 GB RAM built up on P5K Premium/WIFI board.
South Bridge ICH9R setup to AHCI mode with 2×250 SATA drives attached (Seagate Barracuda).
dom0_mem was set to 4GB in /boot/grub/grub.conf. Debian HVM allocated 2 GB memory , Ubuntu 8.04.1 HVM 2.5 -3 GB memory .
In case Ubuntu HH Desktop stub domain install it’s important to have enough memory on the box for Dom0 and DomU. Personally , i was unable to enter graphical installer on C2D box with 4 GB RAM and experienced problems on box with 8 GB RAM during installation procedure, not allocating enough memory for Ubuntu HH HVM. Video card was
in both cases GeForce 8500 GT. View referenced post for details, regarding hvm-stubdom and hvm-dm profiles.
Sequence of screen shots been done during Debian boot up provide some explanation of what was going on :-

I would call it Debian Etch versus (ioemu-stubdom.gz & stubdom-dm ) to perform booting up successfully.

To perform Ubuntu 8.04.1 Desktop successful install in stub domain is important to allocate enough memory for
HVM (stub) DomU ( in my case 2.5 GB vs 2 GB allowed to avoid installer’s hang when “Configuring apt”).
Install itself went very fast and smoothly :-
Following bellow is fragment from Ubuntu HH HVM /var/log/syslog at startup:-

Attempt of VNC setup on Ubuntu Hardy PV DomU at Xen 3.3 CentOS 5.2 Dom0 (all 64-bit)

Posting bellow describes setup Ubuntu Hardy PV DomU via attacment block device to Ubuntu Hardy HVM DomU at the same CentOS 5.2 Dom0. Standard debootstrap procedure has been used to create initial
image on this device. This step allows to avoid “scp” image files from remote Ubuntu HH box to Dom0 and use /dev/sda(X) with prepared image immediately on the same box,referencing the device from Ubuntu Hardy PV profile.
I’ve also attempted to install “ubuntu_desktop” on PV DomU and activate VNC. This procedure seems to have bugs during “ubuntu_desktop” install on image prepared via debootstrap. However, gnome desktop been installed
still appears to be able perform numerous useful functions.

Create Ubuntu Hardy HVM via virt-install at Xen 3.3 CentOS 5.2 Dom0 providing by Xen 3.3 port via http://www.gitco.de/repo/xen3.3.0 .It can be also done and at Xen 3.3 Dom0 been built from source via hvm-profile,e.g. not using
virt-install at all.
Disk attach block device to prepare Ubuntu PV DomU image via debootstrap.

# virsh attach-disk U8HVM –driver phy /dev/sda10 xvdb
Restart U8HVM and issue at Ubuntu HVM DomU (attached disk will be recognized as /dev/sdb) :-

Install CentOS 5.2 & F9 PV DomUs at OpenSuse 11 Dom0 via local HTTP Server (all 64-bit)

It’s well known that OpenSuse’s utility vm-install fails to perform RH PV guests install via NFS shares.
Install from Internet repositories requires software download about 4GB of data for any CentOS 5.X of Fedora PV DomU. Corresponding ISO images have been copied to CentOS 5.2 box running Apache HTTP Server and located on same LAN. Then this images were loop mounted to corresponding folders under /var/www/html. This procedure provided an option for vm-install (via http) RH PV Guests at Xen 3.2.1 OpenSuse 11 Dom0 in pretty short time frame about 40-50 minutes for every DomU been installed.
Actually , Apache Server at Xen 3.2.1 OpenSuse 11 Dom0 may be used as well with some preconfiguration.
However, hardware resources on the Xen box might appear to be not sufficient for good installation performance
in this case.
# cd /etc/apache2
# vi default-server.conf
DocumentRoot “/srv/www/htdocs”
#
# Configure the DocumentRoot
#
<Directory “/srv/www/htdocs”>
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
:wq
<br>
Restart Apache on OpenSuse 11Dom0 and mount loop rhel.iso as follows :-
dhcppc0:/etc/xen/isos # mount -o loop rhel.iso /srv/www/htdocs/rhel
dhcppc0:/etc/xen/isos # df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda7              13G  8.1G  3.9G  68% /

/etc/xen/isos/rhel.iso
4.3G  4.3G     0 100% /srv/www/htdocs/rhel
dhcppc0:/etc/xen/isos #
Since then Apache Server at Xen Dom0 may be used for vm-install via http.

I’ve used different linux box as HTTP server for perfomance reasons.
Start httpd daemon on CentOS 5.2 box located on the same LAN.
Then run :-
# cd /var/www/html/
# mkdir f9
# mkdir rhel52
# cd /etc/xen/isos
# mount -o loop f9.iso /var/www/html/f9
# mount -o loop rhel52.iso /var/www/html/rhel52

Launch browser to http://192.168.1.39/f9 and http://192.168.1.39/rhel52 locally and make
sure , that created repositories are online:-

Now launch browser to http://192.168.1.39/rhel52 from remote Xen 3.2.1 OpenSuse 11 Dom0 to verify
web connectivity and proceed with vm-install to perform CentOS 5.2 PV guest install, referencing local CentOS 5.2 repository.

Perform in the same way F9 PV DomU install (kernel 2.6.25 with pv_ops)

Install OpenSuse 11 DomU at Xen 3.3 CentOS 5.2 Dom0 via local HTTP Server (all 64-bit)

The procedure down here has been developed due to virt-install failure to handle OpenSuse 11 PV DomU
install at Xen 3.3 (3.2),(3.1) CentOS 5.2 Dom0 either via NFS or HTTP shared directory.
Perform initial connect to Apache Server running at Dom0 , deployment and configuration (until first DomU
reboot) via profile openSUSE11PV.cfg.

# cat openSUSE11PV.cfg
name=”OpenSuse11PV”
memory=2048
disk = ['file:/etc/xen/isos/suse11.iso,xvdb:cdrom,r',
'phy:/dev/sdb14,xvda,w' ]
vif = [ 'mac=00:16:3e:4a:f5:00, bridge=eth0', ]
vfb = [ 'type=vnc,vncunused=1' ]
bootloader = “/usr/bin/pygrub”
kernel = “/boot/x86_64/vmlinuz-xen”
ramdisk = “/boot/x86_64/initrd-xen”
vcpus=1
on_reboot = ‘restart’
on_crash = ‘restart’

# xm create openSUSE11PV.cfg
# vncviewer localhost:0
Press “Back” button on startup screen , then select system original setup via HTTP and point installer to Dom0’s IP as IP of HTTP Server, providing URL /suse/ corresponding directory /var/www/html/suse .
ISO image should be previously loop mounted as follows bellow:-
# mount -o loop suse11.iso /var/www/html/suse
Sequence of snapshots is actually step by step installation instruction.





















When OpenSuse DomU first time goes down for reboot, shutdown Suse DomU via “xm” and switch to profile:-
*******************************************************
Final configuration phase & runtime profile
*******************************************************
name=”OpenSuse11PV”
memory=2048

disk = ['phy:/dev/sdb14,xvda,w']
vif =[ 'mac=00:16:3e:4a:f5:00, bridge=eth0']
vfb = [ 'type=vnc,vncunused=1' ]
bootloader = “/usr/bin/pygrub”
kernel = “/boot/vmlinuz-2.6.25.5-1.1-xen”
ramdisk = “/boot/initrd-2.6.25.5-1.1-xen”
vcpus=1
on_reboot = ‘restart’
on_crash = ‘restart’

Run:-
# xm create openSUSE11PV.run
# vncviewer localhost:0
To commit final configuration phase and load PV DomU.

Pygrub & install CentOS 5.2 PV DomU at Xen 3.2 Ubuntu Hardy Dom0 via local HTTP Server (all 64-bit)

Due to known bug virt-install was broken on Ubuntu 8.04 since day of it’s GA and never has been fixed as far as to my knowledge. However, xen-enabled ISO’s like RH’s ones allow to perform PV Guest install via pygrub and repository placed on Apache Server running at Dom0. Notice, that virtual frame buffer would work fine for CentOS PV at
Ubuntu Hardy Dom0 (2.6.24-21-xen). Setup Apache at Ubuntu Hardy Dom0.
# apt-get install apache2
# losetup /dev/loop0 /etc/xen/isos/rhel52.iso
# mkdir -p /var/www/rhel
# mount -o loop /etc//xen/isos/rhel52.iso /var/www/rhel
Installation profile :-
root@boris-desktop:/etc/xen/vm# cat centos52.cfg
name=”RHEL52PV”
memory=2048
disk = ['phy:/dev/loop0,hdc:cdrom,r',
'phy:/dev/sdb14,xvda,w' ]
vif = [ 'mac=00:16:3e:4a:f5:00, bridge=eth0', ]
vfb = [ 'type=vnc,vncunused=1' ]
bootloader = “/usr/bin/pygrub”
kernel = “/images/xen/vmlinuz”
ramdisk = “/images/xen/initrd.img”
vcpus=1
on_reboot = ‘restart’
on_crash = ‘restart’
Proceed with install :-
# xm create centos52.cfg
# vncviewer localhost:0













When DomU will attempt to reboot run :-
# xm destroy RHEL52PV
and switch to runtime profile.
Runtime profile:-
root@boris-desktop:/etc/xen/vm# cat centos52.pyrun
name=”RHEL52PV”
memory=2048
disk = ['phy:/dev/sdb14,xvda,w' ]
vif = [ 'mac=00:16:3e:4a:f5:00, bridge=eth0', ]
vfb = [ 'type=vnc,vncunused=1' ]

Run :-
# xm create centos52.pyrun
# vncviewer localhost:0

Setup VNC at DomU as follows :-
# mkdir .vnc
# cd .vnc
# vncserver :1
Vnc password will be requested by the last command.
Edit ~/.vnc/xstartup and uncomment first two lines.
Make this file as follows bellow:
#!/bin/sh
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80×24+10+10 -ls -title “$VNCDESKTOP Desktop” &
twm &
Make following changes to /etc/sysconfig/vncservers file:-
VNCSERVERS=”1:root”
VNCSERVERARGS[1]=”-geometry 1024×768″
Then run:-
# chkconfig vncserver on
# reboot







Actually, vncserver setup is not required. Changing initdefault from 3 to 5 in /etc/inittab will start Gnome or KDE login automatically via vfb.
# xm create centos52.pyrun
# vncviewer localhost:0







Notice , that F7,F8 PV DomU may be setup at Xen 3.2 Ubuntu Hardy Dom0 in
similar way.

Install OpenSuse 11 PV DomU at Xen 3.2 Ubuntu Hardy Dom0 via local HTTP Server (all 64-bit)

Attempt to reproduce for OpenSuse 11 procedure worked so smoothly for RH’s PV DomUs , described in previous
post, appeared to be a bit more complicated. Pygrub installation profile reading data from HTTP source at Dom0 still worked fine, but Xen 3.2 Ubuntu’s 8.04.1 pygrub failed to read image had been created for OpenSuse 11 PV DomU (/dev/sda11) . Just an ordinary “xm” profile was required to finish configuration and load PV DomU when image was already created on block device, say /dev/sda11. Xenified kernel and ramdisk had to be copied of image device to Dom0 file system. There may be several ways of achieving this goal. I just selected the easiest for myself. Having already CentOS 5.2 PV DomU up and running attached /dev/sda11 via “xm block-attach” to running DomU as “hdb” , mounted /dev/hdb1 inside DomU and scp’ed suse’s xenified kernel and ramdisk to Dom0. Notice, that virtual frame buffer would work fine for OpenSuse 11 PV at Ubuntu Hardy Dom0 (2.6.24-21-xen). Setup Apache at Ubuntu Hardy Dom0.
# apt-get install apache2
# losetup /dev/loop0 /etc/xen/isos/suse11.iso
# mkdir -p /var/www/suse
# mount -o loop /etc//xen/isos/suse11.iso /var/www/suse
***********************
Installation profile :-
***********************
root@boris-desktop:/etc/xen/vm# cat suse11.cfg
name=”OpenSuse11PV”
memory=2048
disk = ['phy:/dev/loop0,hdc:cdrom,r','phy:/dev/sda11,hda,w' ]
vif = [ 'mac=00:16:3e:4a:f5:00, bridge=eth0', ]
vfb = [ 'type=vnc,vncunused=1' ]
bootloader = “/usr/bin/pygrub”
kernel = “/boot/x86_64/vmlinuz-xen”
ramdisk = “/boot/x86_64/initrd-xen”
vcpus=1
on_reboot = ‘restart’
on_crash = ‘restart’
**************
Start install:-
*************
# xm create suse11.cfg
# vncviewer localhost:0
Manage during initial configuration and installation phase for OpenSuse 11 PV DomU exactly as it was done in [1] for CentOS 5.2 DomU. Pygrub’s profiles performing this step are similar for both DomUs.
Only paths to distro’s vmlinuz-xen and initrd-xen are different.















When DomU would attempt to reboot run :-
# xm shutdown OpenSuse11PV
Now we need to copy of the image (/dev/sda11) created during first phase kernel-xen,initrd-xen and
menu.lst ( to write properly extra line for runtime profile) to Dom0. I did it this way :-
# xm create centos52.pyrun
# vncviewer localhost:0
What ,actually, provided login to CentOS PV DomU console.
At Dom0 ran :-
# xm block-attach CentOSP52PV phy:/dev/sda11 hdb
switched to CentOS52PV DomU X-console and mounted partition
with xenified kernel ,initrd and /boot/grub/menu.lst :-
# mount /dev/hdb1 /mnt
# scp /mnt/boot/*-xen /mnt/grub/menu.lst root@IP-Dom0:/etc/xen/vm
then created second phase configuration and runtime profile for OpenSuse 11 DomU as follows:-
**************************************************
Second phase configuration and runtime profile
**************************************************
name=”OpenSuse11PV”
memory=2048
disk = ['phy:/dev/sda11,hda,w']
vif =[ 'mac=00:16:3e:4a:f5:00, bridge=eth0']
vfb = [ 'type=vnc,vncunused=1' ]
kernel = “/etc/xen/vm/vmlinuz-2.6.25.5-1.1-xen”
ramdisk= “/etc/xen/vm/initrd-2.6.25.5-1.1-xen”
extra = “root=/dev/hda1 resume=/dev/hda2 splash=silent showopts”

To proceed with install , run :-
# xm create suse11.run
# vncviewer localhost:0

Install Debian Etch PV DomU with VNC at Solaris Nevada (build 98) Dom0

This posting utilizes same image file for loading HVM and PV Debian Etch DomUs at SNV_98 Dom0. Due to ongoing issue with “rge” driver Solaris Nevada (98) causes faillure to run “apt-get install” at Debian PV DomUs, until checksums offloading at DomU will get disabled via “ethtool”. It also provides a simple way of VNC connection to Debian PV DomU. VNC setup on Debian PV DomU versus Ubuntu Hardy provides just one x-terminal session after connection via vncviewer. However, executing command “gnome-session” in this terminal immediately starts healthy Gnome Desktop with no problems (compare with [1]). Login to Debian HVM DomU console and run :-

Install of build-essentials and ethtool-6 has been done via apt-get install in Debian HVM DomU.
That’s a tricky place , because broken driver for RTL Gibatit NIC at SNV Dom0 have us to use same image file for HVM and PV DomUs to be able run “apt-get install build-essentials” and any other stuff until the point when “ethtool” gets built and checksums offloading may be disabled at PV DomU . It might appear impossible to run “apt-get install” at Debian PV DomU in case when NIC at SNV Dom0 has a broken driver like “rge”.

Pygrub&Loading Ubuntu Intrepid Server PV DomU via serial console at Xen 3.3 CentOS 5.2 Dom0

To load Ubuntu Intrepid Server PV DomU via serial console files vmlinuz-2.6.27-7-server,initrd.img-2.6.27-7-server usually get copied to Xen 3.3 Dom0 and parameters root=”/dev/xvda1 ro”, extra=”2 hvc0″ are included into startup profile. In general , created profile should look like:-

[root@ServerCentOS52 vm]# cat intrepid.conf
memory = 4096
name = “IntrepidPV”
kernel=”/etc/xen/vm/vmlinuz-2.6.27-7-server”
ramdisk=”/etc/xen/vm/initrd.img-2.6.27-7-server”
root=”/dev/xvda1 ro”
extra = ‘2 console=hvc0′
vif = [ 'mac=00:16:3e:00:00:00' ]
disk = [ 'phy:/dev/sdb14,xvda,w']

At the same time “root” & “extra” may be specified via new entry into /boot/grub/menu.lst located at DomU. File /etc/event.d/tty1 should be also modified to work for xen console instead of vfb.
It’s exec line has to reference hvc0 instead of tty1. All changes above been done at DomU allow to load DomU via pygrub and serial console avoiding using virtual frame buffer. First virt-install Ubuntu Intrepid Server HVM DomU and create a new entry into /boot/grub/menu.lst :-

title Ubuntu 8.10 (hvc0) , kernel 2.6.27-7-server
kernel /boot/vmlinuz-2.6.27-7-server root=/dev/xvda1 ro 2 console=hvc0
initrd /boot/initrd.img-2.6.27-7-server
quiet

Next modify /etc/event.d/tty1 as follows

# cat /etc/event.d/tty1
# tty1 – getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.

start on stopped rc2
start on stopped rc3
start on stopped rc4
start on stopped rc5

stop on runlevel 0
stop on runlevel 1
stop on runlevel 6

respawn
exec /sbin/getty 38400 hvc0

Create following pygrub profile at Xen 3.3 CentOS 5.2 Dom0

[root@ServerCentOS52 vm]# cat intrepid.py
memory = 4096
name = “IntrepidPV”
bootloader=”/usr/bin/pygrub”
vif = [ 'mac=00:16:3e:00:00:00' ]
disk = [ 'phy:/dev/sdb14,xvda,w!']

Attempt of prevu Intrepid Xen 3.3 Hypervisor at Ubuntu Hardy Dom0 (2.6.24-21-xen)

Quote:-
This is potentially a more time consuming backport but with Xen 3.3 being a huge improvement over 3.2 it would definitely help Ubuntu server market share to have Xen 3.3 available in Ubuntu 8.04. Many server operators will want Xen 3.3 but will want to continue running the LTS release rather than upgrade to Intrepid.
Current status of backports per Scott Kitterman :-
Because xen-3.3 is a new package for Hardy and so it needs a manual review by the archive admins. This is normal.
https://launchpad.net/ubuntu/hardy/+source/xen-3.3/3.3.0-1ubuntu7~hardy1
shows the status. It won’t be available until it no longer says ‘NEW’ in the builds section.
Proceed with “prevu” build to evaluate Intrepid Xen 3.3 Hypervisor at Hardy Dom0.

# apt-get install prevu
# DISTRO=hardy prevu-init
# wget \

To get HVM able obtain IP address via bridge i had to use vif = ['bridge=eth0'] in
profiles like :-
root@boris-desktop:/etc/xen/vm# cat intrepid.hvm
kernel = “/usr/lib/xen/boot/hvmloader”
builder = ‘hvm’
memory = 1024
name = “IntrepidHVM”
vcpus = 1
vif = [ 'bridge=eth0' ]
disk = [ 'phy:/dev/sdb14,hda,w!','phy:/dev/loop0,hdc:cdrom,r' ]
device_model = ‘/usr/lib/xen/bin/qemu-dm’
vnc=1
boot=’c’
Turning virtual NIC into a paravirtualized mode instead of a fully virtualized.
When vif=['type=ioemu,bridge=eth0'] HVM fails to bring up virtual network interface.

Please be advised , as of November 11 Hardy Backports provide Xen 3.3 packages .
They may be installed nicely via Synaptic Manager.

OpenSuse 11.1 PV DomU at Xen 3.3 Ubuntu Hardy Dom0 (all 64-bit)

Release been tested as PV DomU was Beta 4. Xen’s 3.3 pygrub loads DomU via image created during install utilizing local HTTP source with no problems , compare with native Xen 3.2 Hypervisor behavior on Ubuntu Hardy Dom0 ([1]). Same procedure obviously works at Xen 3.3 CentOS 5.2 Dom0. Due to
failure install Beta 4 in Dom0 (bug submitted) names of xenified kernel and ramdisk are unknown up on image creation, even though it doesn’t cause any problem in case Xen 3.3 Hypervisor back ported from Intrepid Release.
Setup Apache at Ubuntu Hardy Dom0.

Backport Intrepid Xen 3.3 Hypervisor to Ubuntu Hardy Dom0 (2.6.24-21-xen)

As of November 11 Intrepid Xen 3.3 Hypervisor may be back ported to Hardy Dom0 via repositories.
Following bellow is a brief instruction for installation from scratch Ubuntu Hardy Dom0 with 2.6.24-21-xen kernel
running with Xen 3.3 hypervisor. Install Ubuntu 8.04.1 Desktop and remove network manager :-
# apt-get remove network-manager
# gedit /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

# /etc/init.d/networking restart
# apt-get install ubuntu-xen-server

When done activate backports in /etc/apt/sources.list and load Synaptic Manager.
Mark for installation ;-

libxen3-dev
xen-doc-3.3
xen-hypervisor-3.3
xen-utils-3.3

and accept suggested conflict resolution.



Go through install and reboot with Xen 3.3 Hypervisor :-

Pygrub&Loading Fedora 10 PV DomU at Xen 3.3 Ubuntu Hardy Dom0 (all 64 bit)

1.To create loadable Fedora 10 PV image we would have to manage at Xen 3.3 CentOS 5.2 Dom0 either multibooting with Hardy Dom0 or remote , then several “dd” conversions might be required due to “scp” step. To install Fedora 10 PV DomU local NFS share will be utilized. Local Apache Server simulating HTTP mirror may be used as well. Installer provides both options. Attempts to perform install on Ubuntu Hardy Dom0 failed. Looks like Hardy has problems with the most recent Fedora’s file system. ISO image mounted via losetup doesn’t work correct versus it happens on CentOS 5.2.
2. Another approach may be to install F10 HVM DomU at Xen 3.3 Hardy Dom0 and proceed exactly the same way as in case of Ubuntu Intrepid Server. Installed image would have kernel ready to support pv_ops and provide opportunity to load created image via pygrub, e.g. the way to go seems to be an exact reproducing schema been utilized to for Ubuntu Intrepid Server PV DomU install.
However, testing second option i’ve got following error at PV DomU boot up.



Consider first option.
Installation profile :-
[root@ServerCentOS52 vm]# cat f10.cfg
name=”F10PV”
memory=2048
disk = ['file:/etc/xen/isos/f10.iso,xvdb:cdrom,r',
'phy:/dev/sda9,xvda,w' ]
vif = [ 'bridge=eth0', ]
vfb = [ 'type=vnc,vncunused=1' ]
bootloader = “/usr/bin/pygrub”
kernel = “/images/pxeboot/vmlinuz”
ramdisk = “/images/pxeboot/initrd.img”
vcpus=1
on_reboot = ‘restart’
on_crash = ‘restart’

# xm create f10.cfg
# vncviewer localhost:0










Runtime profile will be the same at both CentOS 5.2 and Ubuntu Hardy Dom0s ( Xen 3.3 Hypervisor)
root@boris-desktop:/etc/xen/vm# cat f10.py
memory = 2048
name = “Fedora10PV”
bootloader=”/usr/bin/pygrub”
vif = [ 'bridge=eth0' ]
vfb = [ 'type=vnc,vncunused=1' ]

Xen 3.3.1rc1-pre port to CentOS 5.2 via http://bits.xensource.com mercurial repos and managing PV DomUs in graphical mode

Failure to virt-install F10 PV DomU and repeated issue with CentOS 5.2 in stub domain after same port via
http://gitco.de, upgrading only hypervisor to keep virt-install alive at Dom0, brought me to idea just go through traditional “hg” cloning mercurial repository at http://bits.xensource.com and build local Xen 3.3.1rc1 with 2.6.18.8-xen kernel. Actually, technology based on utilizing local Apache Mirrors along with pygrub profile,referencing installation versions of kernel ( either xenified or supporting pv_ops) and corresponding ramdisk, to create bootable PV DomU image followed by switching to another standard pygrub profile to load DomU with image, been already created, is flexible enough to cancel urgent need in virt-install. Installation PV DomUs for Ubuntu and Debian doesn’t need virt-install as well. Stub domains also work much more smoothly at Xen 3.3.1rc1-pre port to CentOS 5.2 mentioned in the header. In particular, i was able to install CentOS 5.2 in stubdom pretty fast and without any problems. I’ve tested CentOS 5.2 install as PV DomU and as stub domain (view [1],[2] for details) ,F9 PV DomU and openSUSE 11 install as PV DomU (view [3] for details). All mentioned above PV DomUs would be built up with graphical interface straight away.

Install SNV103 PV DomU with ZFS image at Xen 3.3.1 openSUSE 11.1 Dom0 (all 64-bit)

During installation phase we would have to drop to shell and undertake some special actions to prepare runtime profile.Pygrub won’t be able to load DomU utilizing ZFS based image. In particular, ZFS-ID of boot environment will be obtained to compose extra line in runtime profile.

Start install as usual via profile :-

name = 'Solaris103PV'
memory = '2048'
disk = [ 'file:/home/boris/snv103.iso,6:cdrom,r','phy:/dev/sdb12,0,w']
vif = [ 'bridge = br1' ]
bootloader = '/usr/bin/pygrub'
kernel = '/boot/platform/i86xpv/kernel/amd64/unix'
ramdisk = '/boot/amd64/x86.miniroot'
extra = '/platform/i86xpv/kernel/amd64/unix - nowin -B install_media=cdrom'

Select ZFS on image device and request manual reboot. At the end of package deployment phase drop to shell at DomU and run

# bootadm update-archive -R /a

Copy kernel and boot_archive off the image to Dom0

# /a/usr/bin/scp -S /a/usr/bin/ssh \
/a/platform/i86xpv/kernel/amd64/unix \
192.168.1.33:/etc/xen/nevada
# /a/usr/bin/scp -S /a/usr/bin/ssh \
/a/platform/i86pc/amd64/boot_archive \
192.168.1.33:/etc/xen/nevada

Get the ZFS-ID of the /ROOT/snv_103 zpool. First, find out the pool_guid.
Follow [1]:-

# zpool get guid rpool
# NAME PROPERTY VALUE SOURCE
rpool guid 17306096753167233998

1.Installing Opensolaris 2008.11 RC2 on a Linux (RedHat/Centos) dom0

xVM on opensolaris 2008.11

My primary target was testing xVM performance at opensolaris 2008.11(based on 101b Nevada build). Solaris Nevada works smoothly with images located on UFS and zvols.Opensolaris 2008.11 requires only zvol as image devices for Xen Guests to be installed in reasonable time.I believe it’s a known issue caused by ZFS. From my standpoint the most impressive UI feature is Package Manager. It’s really helpful.

Install all members of Virtualization group via Package manager.




# cd /boot/grub/
# ln -s /rpool/boot/grub/menu.lst menu.lst

Add new entry to /boot/grub/menu.lst

Creating zpool :-

# zpool create xvmpool c4t0d0p2 (3)
# zfs create -V 25G xvmpool/snv-disk

Log out root and run:-

$ pfexec virt-manager

Set installation partition to /dev/zvol/dsk/xvmpool/snv-disk
Attempt to use image file like /export/home/images/roo.img , located on ZFS will make virt-manager
(virt-install) performance unacceptable, at least through my experience.

1.Getting xVM to work in Opensolaris 2008.05

Ubuntu Hardy HVM vs PV DomU at opensolaris 2008.11 Dom0

Notice that installation Ubuntu HVM and runtime performance at opensolaris 2008.11 Dom0 is extremely low versus same HVM perfomance at Xen 3.3.1 openSUSE 11.1 Dom0 on the same box with C2D E8400 and 8 GB RAM. Actually, Linux as well as Nevada HVM DomUs demonstrate very low performance even been installed on zvols. Paravirtual DomUs behave at opensolaris 2008.11 absolutely normal been installed on zvol’s images.

Start with install HVM on zvol (/dev/zvol/dsk/bigpool/disk3)





When done:-

# apt-get install build-essential
# apt-get install linux-image-xen

Download ethtool-6 package and install it with intend to disable checksums offloading on PV DomU with image on same zvol. Add one more entry to /boot/grub/menu.lst :-

Scp created ISO image to opensolaris 2008.11 Dom0
and create HVM DomU:-

-f /dev/zvol/dsk/xvmpool/snv-disk -l /export/home/isos/ubuntu-8.10-server-amd64-pv.iso

Add new entry to /boot/menu.lst at HVM DomU:-

Download from [1] new versions of /usr/lib/xen/bin/pygrub and /usr/lib/fs/ext2fs/fsimage.so. This patches address issues mentioned in CRs:
http://bugs.opensolaris.org/view_bug.do?bug_id=6780879

http://bugs.opensolaris.org/view_bug.do?bug_id=6769739
and seems to be uncommitted at mean time.
Per Fred installation via virt-install works on AMD based boxes and fails on Intel. I’ve also tried virt-install on C2D box . Virt-install started , but appeared to fail attach to DomU modified ISO image. That’s why i’ve attempted to load Intrepid Server PV DomU via image been created by HVM installation.

Running 64-bit Solaris 10U6 HVM DomU (2 vcpus) at Xen 3.3.1-RC3 CentOS 5.2 Dom0

Xen 3.3.1-RC3 contains fix for bug SMP 64bit Solaris10u5 cause Xen crash

Bug detailed description:
--------------------------
With Xen unstable, booting SMP 64bit Solaris10u5 will cause Xen crash. Booting
UP 64 bit Solaris10u5 or SMP 32 bit Solaris10u5 has no such issue.
BTW, to boot up 64 bit Solaris10u5 on unstable xen, we should set PSE36=1 by
cpuid=[ '1:edx=xxxxxxxxxxxxxx1xxxxxxxxxxxxxxxxx' ] in hvm guest config file.

RC3 & RC4 handle running mentioned 64-bit HVM with 2 vcpus (C2D box) , what causes openSUSE 11.1 Xen Host to reboot .OpenSUSE 11.1 Xen host may run 64-bit S10U6 HVM with vcpus=1 only. Current Solaris Nevada build 104 has the same limitation. Solaris 10U6 (64 bit) HVM runtime profile for Xen 3.3.1-RC3 Linux Dom0 :-

[root@ServerXen vm]# cat solaris.hvm
name = "S10U6"

memory = "2048"
disk = ['phy:/dev/sda11,hda,w']
vif = [ 'bridge=eth0' ]

Setup LVM based Intrepid Server PV DomU for PV-Grub load at Xen 3.3.1-RC4 CentOS 5.2 Dom0

Been creating Intrepid (lbex) HVM image,supposed to be loaded as PV DomU, i’ve got an issue with default LVM partitioning been done by Ubuntu Intrepid Server. Image been created may be easily loaded at Xen 3.3.X Dom0 via traditional xm-profile by not via “pygrub” or “pv-grub”, expecting /boot partition not of LVM’s type. Up on creating Intrepid HVM image, boot partition and LVM’s Group , containing “/” filesystem and swap as logical volumes have been setup.Notice,that Disk Druid RH’s partitioner always does so by default.
Intrepid KVM with image device (/dev/sdb8) has been created via virt-manager on Ubuntu Intrepid Server dual booting with
Xen 3.3.1 CentOS 5.2 Dom0. Actually, it’s not important where to create this image. It could be also done via standard hvm profile at Xen 3.3.1 CentOS 5.2 Dom0. I have to notice, that “qcow2″ format for image files supported by the most recent python-vm-builder for intrepid’s KVMs is not acceptable for convertion into PV DomU’s images.



Setting up Intrepid HVM at Xen 3.3.1-RC4 CentOS 5.2 Dom0 :-















Once HVM got loaded /etc/event.d/tty1 has been copied to /etc/event.d/hvc0

# tty1 - getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.
start on stopped rc2
start on stopped rc3
start on stopped rc4
start on stopped rc5
stop on runlevel 0
stop on runlevel 1
stop on runlevel 6
respawn
exec /sbin/getty 38400 hvc0

The first time Intrepid PV DomU has been loaded via profile :

[root@dhcppc0 vm]# cat xen.conf
name = 'UbuntuPVS810'
memory = 4096
kernel = '/etc/xen/vm/vmlinuz-2.6.27-7-server'
ramdisk = '/etc/xen/vm/initrd.img-2.6.27-7-server'
disk = [ 'phy:/dev/sdb8,xvda,w']
vif = [ 'bridge = eth0']
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
root = '/dev/mapper/vg01-vol01 ro'
extra = '2 console=hvc0'

At DomU side :-

# apt-get vim
# apt-get upgrade
# apt-get linux-server-image

have been run.
File /boot/grub/menu.lst modified as follows :-

title Ubuntu 8.10, kernel 2.6.27-9-server (PV DomU)
root (hd0,0)
kernel /vmlinuz-2.6.27-9-server root=/dev/mapper/vg01-vol01 ro 2 console=hvc0
initrd /initrd.img-2.6.27-9-server
quiet

Then Intrepid PV DomU may be loaded via profile :-

[root@dhcppc0 vm]# cat IntrepidPVG.pv-grub
name = "InterpidPV-Grub"
memory = 4096
vcpus = 1
disk = [ 'phy:/dev/sdb8,xvda,w' ]
vif = [ "bridge=eth0" ]
kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz"
extra = "(hd0,0)/grub/menu.lst"

Install Intrepid Server PV DomU at Xen 3.3.0 Intrepid Server Dom0 (kernel 2.6.26-1-xen-amd64)

Attempting to reproduce How-To: Run Xen in Ubuntu Intrepid without compiling a Kernel by yourself from blog Chris’ World ([1]), i had to disable any xen bridge definitions inside /etc/xen/xend-config.sxp and manually add the bridge to /etc/network/interfaces configuration file.
Otherwise, i wouldn’t be able get xen-bridging network running with debian 2.6.26-1-xen-amd64 kernel under Xen 3.3 Interpid Hypervisor installed on the system via Synaptic Manager.

Setup Xen 3.3.0 Ubuntu Intrepid Server Dom0 via build xen-kernel based on http://xenbits.xensource.com/ext/linux-2.6.27-xen.hg

This posting, in general, follows up Clayton Shepard’s “Howto Ubuntu Intrepid Ibex 8.10 Xen Dom0″([1]). However, several things went different. First, i had to disable XFS Support when building Novell’s kernel, otherwise build just exited with error. Second, i still had to comment out “xen” bridging initiated via /etc/xen/xend-config.sxp and manually add the bridge to /etc/network/interfaces configuration file. I didn’t take care of “xvc0″ and used virtual frame buffer when tested CentOS 5.2 PV DomU and Ubuntu Intrepid Server HVM and PV DomUs at Xen 3.3.0 Intrepid Server Dom0 based on Novell’s kernel .View Setup Intrepid Server PV DomU via xen-image-create&debootstrap at Xen 3.3 Intrepid Server Dom0 with Novell’s Xen-ified kernel 2.6.27-5

Testing Dom0 functionality , i didn't follow [1] with xen-create-image along with debootstrap
and reproduced samples from [3] and [4].
Compiling Novell's kernel with DomU support
does allow to test xen-create-image, but
Ubuntu Intrepid PV DomU will report kernel
2.6.27-5 via "uname -a".
Intrepid Server PV DomU runtime snapshots:-





CentOS 5.2 PV DomU runtime snapshots:-





To enable serial console for Intrepid Server PV DomU loaded
it via profile :-

root@IntrepidSRV:/etc/xen/vm# cat intrepid.conf
name = "IntrepidPV"
kernel="/boot/vmlinuz-2.6.27-7-server"
ramdisk="/boot/initrd.img-2.6.27-7-server"
root="/dev/xvda1 ro"
extra = '2 console=hvc0'
vif = [ 'bridge=br0' ]
disk = [ 'phy:/dev/sdb3,hda,w']

previously created file /etc/event.d/hvc0 at DomU.
Then modified /boot/grub/menu.lst correspondently for
pygrub's serial console profile:-

name = 'IntrepidPV'
bootloader="/usr/bin/pygrub"
memory = 4096
disk = ['phy:/dev/sdb3,hda,w']
vif = [ 'bridge=br0' ]
on_reboot = 'restart'
on_crash = 'restart'

Serial console output :-
