> That might be okay, although even that might appear to change if we > implement things like VM fork in future. Hmmm. That sounds interesting. If was done with CoW, the fork could be almost instant. You could freeze a running domain, fork (copy) it (and snapshot the underlying lvm volume), and run the copy to test a scenario, then roll it back again and test another. Is that achievable using any combination of existing features at all? Sounds like we need a domain UUID and an instance UUID...
