Xen Virtualization on Linux and Solaris

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.

I would also name this post xen-image-create&debootstrap vs python-vm-builder in regards
of pre-building Xen Guests at Ubuntu Intrepid Server.View Bug Report ([3]) for details. Install Interepid Server Dom0 with with Novell's Xen-ified kernel, enabling Dom0 and DomU support at a time.

View [1],[2] for details.Tune xen-tools scripts per [1] and create Intrepid PV DomU. Actually, images been created via xen-create-image allow to upgrade DomU to real Intrepid Server PV DomU.
I mean to perform:-


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

and switch DomU's kernel to vmlinuz-2.6.27-9-server.
Afterward images may be scp'ed to any Xen 3.3.X Linux Dom0(64-bit) and corresponding Intrepid Server PV DomU loaded for instance at Xen 3.3.1-RC4 CentOS 5.2 Dom0 (64-bit).So, xen-image-create appears to be responsible to prebuild Xen Guest instead of the most recent release of python-vm-builder.


[root@ServerXen31 root]# cat createImage
xen-create-image --force --hostname=IntrepidPVS --size=6Gb \
 --swap=1Gb --ide --memory=2Gb --arch=amd64 \
 --dir=/etc/xen/images  --kernel=/boot/vmlinuz-2.6.27.5 \
 --initrd=/boot/initrd-2.6.27.5.img \
 --install-method=debootstrap --dist=intrepid --mirror=http://archive.ubuntu.com/ubuntu/ \
 --passwd --accounts=root  --dhcp

Load DomU via profile:-


kernel      = '/boot/vmlinuz-2.6.27.5'
ramdisk     = '/boot/initrd-2.6.27.5.img'
memory      = '2048'
#
#  Disk device(s).
#
root        = '/dev/hda2 ro'
disk        = [
                  'file:/etc/xen/images/domains/IntrepidPVS/swap.img,hda1,w',
                  'file:/etc/xen/images/domains/IntrepidPVS/disk.img,hda2,w',
              ]
#
#  Hostname
#
name        = 'IntrepidPVS'
#
#  Networking
#
dhcp        = 'dhcp'
vif         = [ 'mac=00:16:3E:7D:DB:85' ]
#
#  Behaviour
#
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
console='xvc0'

Run at DomU:-


# apt-get upgrade
# apt-get install linux-image-server
# shutdown -P now

Now load DomU via profile :-


kernel      = '/etc/xen/vmlinuz-2.6.27-9-server'
ramdisk     = '/etc/xen/initrd.img-2.6.27-9-server'
memory      = '1024'

root        = '/dev/xvda2 ro'
disk        = [
                  'file:/etc/xen/images/domains/IntrepidPVS/swap.img,xvda1,w',
                  'file:/etc/xen/images/domains/IntrepidPVS/disk.img,xvda2,w',
              ]

name        = 'IntrepidPVS'
vif         = [ 'bridge=br0' ]

on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

console='hvc0'

At DomU ran tasksel to install Basic Intrepid Server,Opensshserver,Ubuntu Desktop
Now scp image files to remote Xen 3.3.1-RC4 CentOS 5.2 Dom0 and attempt to load DomU:-
[root@dhcppc0 xen]# cat IntrepidPVSRV-9.cfg


kernel      = '/etc/xen/vmlinuz-2.6.27-9-server'
ramdisk     = '/etc/xen/initrd.img-2.6.27-9-server'
memory      = '4096'
root        = '/dev/xvda2 ro'
disk        = [
                  'file:/etc/xen/images/domains/IntrepidPVS/swap.img,xvda1,w',
                  'file:/etc/xen/images/domains/IntrepidPVS/disk.img,xvda2,w',
              ]
name        = 'IntrepidPVS'
vif         = [ 'bridge=eth0' ]
# dhcp        = 'dhcp'
# vif         = [ 'mac=00:16:3E:7D:DB:85' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
