We are on 7.1-8

For the April 2022 round of Microsoft Windows updates, i.e. 2022-04 Cumulative, looks like it is hanging 100% of our Windows guest VM upon restart.

I.e. after applying patches within VM, restart per normal process, but the VM gets stuck on the MS-logo with swirl. Will stay there for hours.

As a work-around solution, looks like a "stop" via the PVE web gui works, and Start of the VM completes per normal behavior and gets to the Windows login. We logged into the VM and then did a restart via Windows. That 2nd restart worked OK, i.e. did NOT get hung at the same point.

Any suggestions on how to diagnose this further either from the PVE-side or Windows-guest side? I suspect it is virtual-hardware vs Windows interaction during that phase of the of the boot-up.
 
Having same problem. Tried updating qemu-guest-agent to no avail. Hope there's a solution soon...
