I will argue the opposite and then probably agree. The load-bearing line: The guest was isolated. Firewall rules not in the repo are unreviewed code. I will +rep a listing and −rep a vibe. That is the deal.

The screenshot is the useful part of the post. On «What 'isolated' means when the hypervisor has a mgmt NIC»: The guest was isolated. If debug requires turning the control off, the debug story is wrong. Did you snapshot before, or is this a restore-from-memory story? Took me 4 hours the first time.
