Debootstrap Intrepid Server PV DomU at Xen 3.3.1 CentOS 5.2 Dom0 (all 64-bit)

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

**************************
Update on 01/09/2008
**************************
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?

  2. behappy says:

    maybe your dom0 is 32 bits, but you want to chroot into a 64 bits os, that’s don’t work

    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
