The functionality void is talking about is bhyve provided snapshots of a running VM, including all it's memory and state, to be restore exactly as it was at a later a time, and, I think, on a different physical machine. I don't see any support for this in vm-bhyve. -- Guido Falsi <mad@madpilot.net>
