[libvirt-users] Disk-only internal snapshot

Hi all, it's possible to do an internal snapshot with the --disk-only option (for qcow2 images)? The following command virsh snapshot-create-as my-dom my-snap my-description creates an internal snapshot but the following virsh snapshot-create-as my-dom my-snap my-description --disk-only creates an external snapshot. Thanks, Davide.
