Citrix XenServer

Below are directions for converting a Ubuntu 10.04 LTS-based Turnkey Linux appliance from running on Citrix XenServer in HVM-mode to PV-mode, enabling the install of Xen Tools. Instructions assume the TKL Appliance is already installed with the Ext3 filesystem and running on Citrix XenServer.

Please note, directions were adapted from those used to convert the mainstream Ubuntu 10.04 LTS distribution. However, the TKL appliance is modified slightly, so it is unknown still what the official conversion method should be. Appliances appear to be stable.

• Ubuntu Guest Console (Configure Guest):

apt-get update && apt-get install linux-image-generic-pae
cp /etc/init/tty1.conf /etc/init/hvc0.conf
nano -w /etc/init/hvc0.conf # replace all tty1 with hvc0
shutdown -P now

• Citrix XenServer Console (Configure XenServer):

xe vm-list power-state=halted # write down UUID for TKL VM
xe vm-param-set uuid=<UUID> HVM-boot-policy= # leave blank after equals sign
xe vm-param-set uuid=<UUID> PV-bootloader=pygrub
xe vm-disk-list uuid=<UUID> # find VB disk UUID
xe vbd-param-set uuid=<VBD UUID> bootable=true
# Start appliance and restart XenCenter Manager

• Ubuntu Guest Console (Install XenTools)

mount /dev/xvdd /mnt (OR mount /dev/cdrom /mnt)
dpkg -i /mnt/Linux/xe-guest-utilities*i386.deb
# OR dpkg -i /mnt/Linux/xe-guest-utilities*amd64.deb for 64-bit appliances
umount /mnt
sudo reboot
