This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it’s often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).
I do not issue any guarantee that this will work for you!
