[lago-devel] Snapshot with memory of Engine/host VMs?

Hi, I have been playing with using Lago snapshots to restart oVirt system tests from a certain point without all the preceding initialization and tests. The primary purpose is to save time when running a suite over different data center compatibility versions but it could be also useful e.g. when writing and debugging tests. However since `lagocli snapshot' makes disk-only snapshots the VMs get restarted when they are reverted. This may cause various problems. For instance, when I snapshot/revert before running add_dc test then verify_notifier test fails -- I assume due to the event being initiated before the snapshot and completed after the snapshot, so it's missing in after-revert runs. Snapshots with memory should resolve similar issues. Is it possible to make such snapshots in Lago? I'd also like to clarify how is `lagocli revert' supposed to be used. It seems to basically work as such but I could experience network accessibility problems of the reverted Lago VMs. lagocli stop + revert + start seems to be a safer way of reverting to a snapshot. How should `lagocli revert' be used properly? Thanks, Milan
