[Xen-users] How to make snapshot disk backup of Xen Guest Domain

[KC LO <kclo2000@xxxxxxxxx>]

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!
