Hi all,

I have created a DomU guest based on the following method :-
1) I create a LV with size 6GB : lvcreate -L 6G
2) I setup a new guest DomU with /dev/VolGroup00/vm1 as disk device
3) In DomU, I use /dev/hda as device to create partition for /boot, /,
and swap without using LVM
fdisk -l /dev/hda

Disk /dev/hda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot      Start         End      Blocks   Id System
/dev/hda1   *           1          13      104391   83 Linux
/dev/hda2              14         521     4080510   83 Linux
/dev/hda3             522         782     2096482+ 82 Linux swap / Solaris

I am now going to do snapshot disk backup at Dom0 for DomU. I have read Internet that I can do

lvcreate -L 1G -s -n guest_snapshot /dev/VolGroup00/vm1

to create a Logical volume guest_snapshot.

How can I mount the partition(/dev/hda1, /dev/hda2) under this volume guest_snapshot to do backup

Thanks!
