You can either use a recovery system without encryption and without LVM, or rename its volume-group name. You just need to do "cryptsetup open...", and the volume group of the system to be recovered will automatically emerge.
In case of two encrypted-LVM-volumes, you need to rename the vg name of the recovery system. You should *not* unlock the system-to-be-recovered yet.
Xen has made it clear how to rename the volume group:
vgrename kubuntu-vg rescue-vg
Then you must verify that /etc/fstab in the RESCUE system contains no
references to "kubuntu-vg" and you might also have to rerun
"update-grub" if you want to keep it this way.
