Xen: How to Convert An Image-Based Guest To An LVM-Based Guest

[ Thanks to Falko Timme for this link. ]

"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"
