Setup VNC at Ubuntu Jaunty Server PV DomU at Xen 3.4 Dom0 (kernel 2.6.30-rc1-tip) via IP6v

April 19, 2009

Well known schema ([1]) tuning gdm.conf and running Xvnc via xinetd worked fine for Ubuntu Hardy and Intrepid PV DomUs fails for Ubuntu 9.04 Server PV DomU . Setup vncserver to start via /etc/rc.local and /usr/bin/gnome-session via ~/.vnc/xstartup known as a way to manage on Debian Etch. I’ve also noticed :-
Remote Desktop Viewer VNC over IPv6: works on Ubuntu 9.04 Jaunty (Alpha 6)
Yes IPv6 works:-



Auto detection Ubuntu Jaunty PV DomU from another remote Intrepid Server on the same LAN :-





************************
UPDATE on 04/21/2009
************************
Activation Remote Desktop access causes vino-server to start up
automatically. As appears it’s PPID is PID of /usr/bin/gnome-session. Vino-server stop/start via command line :-

gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled false
gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled true




Activating remote access to Jaunty Server PV DomU via old fashioned vnc connection ( still required).

In general, port goes as usual . However, attempt to create
initial ramdisk for 2.6.18.8-xen kernel fails due to known bug for mkinitrd. Undocumented option –allow-missing provides
a workaround to succeed with mkinitrd for xen-ified kernel
To port Xen 3.4-rc3-pre to xen disabled CentOS 5.3 instance (64 bit) install the most recent version of git and mercurial (hg).

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

Determine the name of the Xen Linux kernel version that was installed.

# ls /lib/modules

There should be a directory for the Xen Linux kernel (e.g.2.6.18.8-xen)
Generate the module dependency list and map files

# /sbin/depmod 2.6.18.8-xen

Create the Xen initial ramdisk image.
Per Bug 488991 - mkinitrd erroneously inserts dependencies to dm-mem-cache

# /sbin/mkinitrd --allow-missing /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen

Disable tls

# mv /usr/lib64/tls /usr/lib64/tls.disabled

Set xend service to start

# /sbin/chkconfig –add xend
# /sbin/chkconfig xend on

Install bridge-utils:-

# yum install bridge-utils

**************************************************************
Edit /boot/grub/grub.conf and copy one of the existing boot entries to make the required changes for Xen and reboot into new kernel.

Port Xen 3.3.1 to CentOS 5.3 via http://gitco.de

April 4, 2009

This posting follows up recent discussion at xen-users mailing list regarding functionality of virt-install and virt-manager after Gitco’s Xen 3.3.1 Hypervisor Upgrade on CentOS 5.3(2). Via the posting bellow i try to demonstrate that Gitco’s upgrade of libvirt-python, python-virtinst,qemu packages and Xen Hypervisor itself seems to be a nice job with no serious issues keeping libvirt and virt-install (virt-manager) utility pretty stable at runtime. I also state that suggestion of use xen-tools & rinse on Xen Systems with libvirt abilities ([1]) doesn’t look to me right way to manage vs utilizing debootstrap on Debian and Ubuntu Xen hosts, providing libvirt for the KVM only.
Current port has obvious advantages as significantly more stable VNC connections to DomUs, virt-manager utility providing option of install PV DomUs via local HTTP mirror and managing DomUs been created via virt-install or via virt-manager.Occasionally vnc sessions gets crashed, however reconnection to DomU works pretty stable,requiring just one attempt.
I was able successfully tested CentOS 5.2(3) and F10 PV DomU installs via virt-manager utilizing as source local Apache Mirror, created via loop mounting ISO image to /var/www/html/corresponding_folder
Original download been done from http://gitco.de/repo/xen3.3.1 :-

# virt-install -n CentOS5PV -r 1024 -p –vnc \
-f /etc/xen/images/CentOS5.img -l nfs:192.168.1.34:/mnt/tmp







To get network running at CentOS 5.2 DomU, installed via NFS share, i had to disable checksum offloading at DomU:

/usr/local/sbin/ethtool -K eth0 tx off

Virt-manger install via HTTP local mirror built up same DomU with no network issues.



Install PV DomU via virt-manager:-





















Install Fedora 10 PV DomU via virt-manager:-

# chkconfig httpd on
# mkdir -p /var/www/html/f10
# mount -o loop /etc/xen/isos/f10.iso /var/www/html/f10

Submit http://IP-Dom0/f10 as installation source to virt-manager and proceed
as normal :-
