As appears debootstrap RPM developed for Fedora 9 works fine at Xen 3.3.1 CentOS 5.2 Dom0 and provide an option to create Intrepid Server PV Guest via debootstrapped Ubuntu’s image in RH’s Xen Dom0 environment. Install F9’s rpm then debootstrap would understand non Ubuntu Environment:-
# rpm -ivh debootstrap-1.0.8-1.fc9.noarch.rpm
Prepare LVMs for install:-
# lvcreate -n ubuntu -L12G /dev/vgxen
# lvcreate -n ubuntu-swap -L4G /dev/vgxen
# mke2fs -j /dev/vgxen/ubuntu
# mkswap /dev/vgxen/ubuntu-swap
# mkdir -p /mnt/xen
# mount /dev/vgxen/ubuntu /mnt/xen
Create missing symlink:-
# ln -s /usr/share/debootstrap/scripts/gutsy \
/usr/share/debootstrap/scripts/intrepid

Fedora 10’s debootstrap-1.0.10-1.fc10.noarch.rpm has this symlink already created. Moreover debootstrap-1.0.10-1.fc10.noarch.rpm been installed on Xen 3.3.1 openSUSE 11.1 Dom0 provide comletely functional debootstrap utility to create Intrepid Server, Hardy Heron PV DomUs at openSUSE 11.1 Dom0 in the same way as described bellow.
Deboostrap new Intrepid Guest:-
# debootstrap --arch=amd64 \
--include=linux-image-server,grub \
--components=main,universe,multiverse intrepid \
/mnt/xen http://us.archive.ubuntu.com/ubuntu/
Once that has finished chroot into the new debootstrapped tree :-
# chroot /mnt/xen
# export LANG=C
Create /etc/fstab:
# cat /etc/fstab
/dev/xvda1 / ext3 defaults 0 1
/dev/xvdb1 none swap defaults 0 0
proc /proc proc defaults 0 0
Create a folder for GRUB menu and update the config
# mkdir -p /boot/grub
# update-grub
Edit /boot/grub/menu.lst
– add “console=hvc0” to both kernel lines (normal and recovery mode)
Setup a getty on the Xen console (hvc0):
# cd /etc/event.d
# cp tty1 hvc0
# sed -i -e "s/tty1/xvc0/g" hvc0
Remove references to the hardware clock; these will cause the DomU to hang:
# update-rc.d -f hwclockfirst remove
# update-rc.d -f hwclock remove
# rm /etc/udev/rules.d/85-hwclock.rules
Configure network interfaces (/etc/network/interfaces):-
# cat /etc/network/interfaces
# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Create /etc/hosts file
# cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 IntrepidPVH
Create /etc/hostname file
# cat /etc/hostname
IntrepidPVH
Exit chroot and unmount the filesystem.
# exit
# umount /mnt/xen
Start DomU via profile:-
bootloader = '/usr/bin/pygrub'
memory = 2048
name = "ubuntuPV"
vif = [ 'bridge=eth0' ]
disk = [ 'phy:/dev/vgxen/ubuntu,xvda1,w', 'phy:/dev/vgxen/ubuntu-swap,xvdb1,w' ]
At this point i had to bring /etc/apt/sources.list from remote Intrepid Server installed on bare metal.
# apt-get update
Run tasksel at DomU to install Basic Ubuntu Server and OpenSSHserver. Rebooted DomU:-
# apt-get upgrade

I am also doing a similar setup but run into a problem when I try to chroot in the env.
chroot /vserver/vm_base
chroot: cannot run command `/bin/bash’: No such file or directory
any ideas?
maybe your dom0 is 32 bits, but you want to chroot into a 64 bits os, that’s don’t work
Thanks for this post, I try to install a Debian on Fedora distribution, on OVH server…
😉
Thanks for the post… but i run in a problem i get no login i can only login with ssh or in recovery mode.
i think i did the console stuff right but maybe u have a tip for me. 😉
I believe problem is here:-
Edit /boot/grub/menu.lst
– add “console=hvc0″ to both kernel lines (normal and recovery mode)
Setup a getty on the Xen console (hvc0):
# cd /etc/event.d
# cp tty1 hvc0
# sed -i -e “s/tty1/xvc0/g” hvc0
