I think this should not be a problem.

Try this (in initramfs shell):
vgchange -a y
this should bring up all volume groups
It seems that there is no script to bring up lvm in your initrd. Check the
contents of /script (in initramfs) or /usr/share/initramfs-tools/scripts if
there is a script "lvm". Maybe regenerating the initrd might help. Try this
(on normally booted system):
update-initramfs -u -k 2.6.18-xen
(At least this should work on debian, I expect ubuntu to be similar)
