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...
