I'd say they'd be lost/erased (Eblake/others would correct me if I'm wrong). When you do a revert, you'd be at the same state when you created the snapshot. Also, you haven't mentioned if you're using internal snapshots, or external. Assuming you're using QEMU internal snapshots (original and the delta are in the same qcow2 file), the virsh man page (section 'snapshot-revert') gives you some details including risk scenarios. -- /kashyap
