If host is using LVM for disk partitioning and uses logical volumes for VM disks, it is possible to do LVM 'snapshots' and these snapshots can then be backed up, all without shutting down the VMs.
Note that making an LVM snapshot, alone, will not provide a consistent image for a backup. If you want to back up a snapshot of a running system, you should use "virsh snapshot-create" to capture the complete state of the system.

Backups from within the guest will typically be much smaller. I'm working on a flexible snapshot script that supports multiple storage types.
