Server looses connection on VM shut down

[NOIDSR]

Hi guys,

I just recently upgraded PVE from 6 to 7 and everything is working ok except one thing. When I shut down one of my VM's (passtrough win10) my browser looses connection to the server although computer is still running. So then I have to manually reboot my computer to restore the connection. I run also MACOS and Ubuntu VMs and it shuts down normally. Any ideas?

I wanted to post here logs as a code but was getting message that my post is too large.

Post the syslog rather as .txt file - important for anylaysis would be to know exactly when the VM shutdown happened. Also useful would be to have a information about VM and other configuration - all this can be seen in a pvereport.

OK thanks! Attached log file. Reboot happened 19:49:39.

And the pvereport is also attached.

AFAICS VM 201 is the respective Windows VM. It was started just a few minutes before the reboot, but I cannot see any shutdown of it. Maybe the shutdown was performed inside the VM. For clearer diagnosis it would be helpful to make the following steps in certain intervals (at least 2 minutes between each of them) and note the exact time/date of them:
- start Windows VM
- shutdown Windows VM
- wait until shutdown is complete
- reboot host (if it is still blocked after > 2 min)
and then investigate the related syslog

OK, understood, but like I said on VM shutdown I totally loose a connection with the server. So I cannot see that the shutdown is complete. It seems on my display windows shut down correctly until black screen but then PVE gui becomes inaccessible. I cannot also access the server via ssh at that moment even though I see server machine is up and running (light are on and fans). The only option would left to do is to do a hard reboot. These logs that I provided I copied after I did a hard reboot and the system was back online.
