“Also, LVM-based guests are easier to back up (using
LVM snapshots).“2 Converting The Images To LVM
“Before we convert the images, we must shut down the guest:
xm shutdown xen1.example.com
“Then we create logical volumes of the same size as the disk
images, e.g. as follows:lvcreate -L4G -n xen1_root vg0
lvcreate -L256M -n xen1_swap vg0“This creates the logical volumes /dev/vg0/xen1_root (4GB) and
/dev/vg0/xen1_swap (256MB):lvdisplay”
