How would you > go about doing that? Say you were on snapshot A and the guest has a problem. The easiest fix is reverting to snapshot A, but you want to investigate it anyway. You create snapshot B with --inactive and, if you want, you can move the snapshot to another machine to activate it and look at it more calmly. If the problem reproduces, you can create another inactive snapshot, and so on. Alternatively, say the easiest fix is stopping and starting a daemon, but again you want to keep a snapshot to investigate it anyway. You can create the inactive snapshot B and stop/start the daemon _while the system is live and running under snapshot A_, i.e. without manually shutting down and rebooting. Is this clearer?
