Xen 3.3.1 port to Ubuntu Intrepid Server via Novell’s Xen-ified kernel 2.6.27.5

The root cause for port mentioned above is to run 64-bit Solaris 10U6 HVM on SMP box with several vcpus. Install openssl,x11(xorg-dev),gettext,python-devel packages required by Xen and bcc&libc6-dev-i386 via Synaptic Manager.The last two packages are needed to compile “hvmloader” and related binaries.

# cd /usr/src
# tar zxvf xen-3.3.1.tar.gz
# cd xen-3.3.1
# make xen
# make install-xen
# make tools
# make install-tools

Compile "hvmloader"

# cd tools/firmware
# make
# make install

Install Novell's Kernel per [1]:-

# apt-get install build-essential libncurses5-dev gawk mercurial
# mkdir -p /home/boris/build/linux-2.6.27-xen
# cd /usr/src/
# hg clone http://xenbits.xensource.com/ext/linux-2.6.27-xen.hg
# cd linux-2.6.27-xen.hg
# make O=/home/boris/build/linux-2.6.27-xen/ \
menuconfig
# make O=/home/boris/build/linux-2.6.27-xen/ -j12
# make O=/home/boris/build/linux-2.6.27-xen/ \
modules_install install
# depmod 2.6.27.5
# mkinitramfs -o /boot/initrd-2.6.27.5.img 2.6.27.5

Setup /etc/init.d/xend and xendomains to automatic startup
Reboot the system with grub’s entry:-

title Xen 3.3 / Ubuntu 8.10, kernel 2.6.27-xen
kernel /boot/xen-3.3.1.gz
module /boot/vmlinuz-2.6.27.5 root=/dev/sdb1 ro console=tty0
module /boot/initrd-2.6.27.5.img

Solaris 10U6 HVM installation profile:-

name = "S10U6"
builder = "hvm"
memory = "2048"
disk = ['phy:/dev/loop0,hdc:cdrom,r','phy:/dev/sdb3,hda,w']
# disk = ['phy:/dev/sdb3,hda,w']
vif = [ 'bridge=eth1' ]
device_model = "/usr/lib64/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
cpuid=[ '1:edx=xxxxxxxxxxxxxx1xxxxxxxxxxxxxxxxx' ]
vnc=1
boot="cd"
usb=1
usbdevice="tablet"
vcpus=2
# serial = "pty" # enable serial console
on_reboot = 'restart'
on_crash = 'restart'

HVM installer dropped into text mode in my case. However, it didn't affect X-Server startup during runtime.

  1. I have to say, I can not agree with you in 100%, but it’s just my opinion, which indeed could be wrong.
    p.s. You have a very good template for your blog. Where have you got it from?

  2. dbaxps says:

    1. It was default template
    2. In meantime i permanently use Suse’s 2.6.27-5 xen-ified
    kernel under Xen Unstable. To be able to verify does
    ongoing issue belong to Xen or to pvops kernel (2.6.29-rcX), which both are under heavy development.
    That’s for development and testing, not for production.

  3. YAA Adding this to my bookmarks. Thank You

  4. site says:

    Have you considered adding some differing opinions to the article? I think it might enhance everyones understanding.

  5. Actually when someone doesn’t understand after that its up to other viewers that they will
    help, so here it occurs.
