[CentOS-virt] About doing backups with kvm guests

Hi all,

I have two centos 5.4 servers that I use to run several windows kvm guests (10). All works ok (more or less) but I have a problem with backups.

These windows guests are configured to use lvm partitions as a virtual disks. My problem is when I need to do guests backups.

which is the best form to backup and restore these windows guests? Some examples? I see snapshot's lvm option, but I think that this option it is not valid for windows guests... probably I need to use dd?? But if i use dd, how can I restore lvm image onto another host with lvm partitions?

Thanks.
