I did a system upgrade on a debian VM that broke a few things, and now I want to roll back the VM but I am not sure how. I have all the snapshots, I know that if I roll back a month or two, then I destroy all snapshots in between (would like to avoid that in case the rollback fails for some reason).
What is the best way to do this? Probably clone and then boot the VM from a clone to preserve the original, but how do I do that?
