• Create this disk layout.

Number  Start   End     Size    Type     File system     Flags
1      1049kB  48.0GB  48.0GB  primary  ext4            boot
2      48.0GB  50.0GB  2000MB  primary  linux-swap(v1)
3      50.0GB  (rest of disk)  primary                  lvm

• Make a new volume group called vm4_storage and include partition 3 as the first PV.

• Run this on an existing VM host to get a list of packages to copy to the new host.

dpkg --get-selections > vmhost.dpkg-selections

• After copying that file to the new host, do this on the new host to install those packages.

sudo apt-get install dselect
sudo dselect update
sudo dpkg --set-selections < vmhost.dpkg-selections
sudo apt-get -y update
sudo apt-get dselect-upgrade

• Make xen boot instead of linux.

dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen

• Set up your drbd volumes in /etc/drbd.d to mirror to whatever other VM host. Then reload drbd and kick off your syncs.

scp vm2:/etc/drbd.d/* /etc/drbd.d/
service drbd restart

• While that's moving, copy your Xen configs from another VM host.

scp vm2:/etc/xen/*.cfg /etc/xen/

That's probably not exactly right but it's something like that. Good luck.
