Hi Arnar

Of course its possible, and there are several options.
So your guest is on a partition. A physical partition or a LVM LV?

For a LVM LV you can do the following (using the LVM snapshot) without
shutting down the domU:

lvcreate -s /dev/vg/domU -L1G -n domU_snap
mkdir /mnt/domU_snap
mount /dev/vg/domU_snap /mnt/domU_snap
tar cvjpf /storage/path/domU_snapshot.tbz /mnt/domU_snap
lvremove /dev/vg/domU_snap


For a physical partition, you should shutdown the domU first (probably
pausing is also ok).
In this case, you can use the dd command for the backup (check the archives).
virt-clone is also an option.


Cheers,
N.

Hi,
Just setup a guest on a Dom0 (CentoOS 5.2) and would now like to clone
or
copy that host to another Dom0 (CentOS 5.2).
Is that possible ?

Guest uses a partition so I can't copy the image file over.
The only thing I've found is about migrating a guest between Dom's.

Best Regards,
