i can now create snapshots if using --disk-only, but i guess this is an "external" snapshot? which leads to other problems, like not being able to delete it:
>virsh snapshot-create-as orb-template-ubuntu 'test_snapshot_3' 'test snapshot 3'
error: operation failed: Error -22 while writing VM
>virsh snapshot-create-as orb-template-ubuntu 'test_snapshot_3' 'test snapshot 3' --atomic
error: operation failed: Error -22 while writing VM
