Sounds good. We would then remove the mapping on shutdown / stop, I suppose? How about Hibernate / Pause? I can see a case for both here.. That way we could also easily add a IP configuration section to the VM configuration, which seems convenient from my POV. I'll take a shot at implementing it this way in the meanwhile.
