I'll backup the VM (from Windows) and probably take a QCOW snapshot of the virtual disk just in case, but I'd be interested to know if: * You're running X11 or Wayland * Your virtual display is QXL, passthrough of a second GPU, or something else * You use VNC or Spice
QXL, X11, Spice.I was able to reinstall Windows 10 on the same VM, and isolated one clue. A VM-initiated reboot always fails, goes into "Preparing Automatic Repair", then bluescreens and tells me that something is corrupted (I forget the details), and there are no available restore points.
But this is a bald-faced lie. But if I force off, and boot again, Windows 10 comes up like there's nothing wrong. Normal boot.
This continued to happen after a fresh Windows 10 install. If I initiate a reboot from the Start menu, I don't even see the bios screen flash by. The stupid thing immediately lands into "Preparing Automatic Repair". But a full shutdown and a boot is fine.
In hindsight, post-upgrade, my VM was probably ok, but it led me to believe that it was bricked, leading me to wipe everything and reinstall. It was very convincing. I am not amused.
At least I tested how well the recovery USB thumb drive, that I prepared earlier has worked. It worked splendidly.
