I have a problem with only one VM.
That VM for unknown reasons sometimes loses guest agent. This is pretty bad, because that makes also the backup impossible, since I do backups to PBS with stop mode.
Is there a known issue with this config?
I had it once before, did not think much of it and upgraded virtio tools to 0.1.285. It worked after the update for some time but know seems to act up again sporadically.
The probably strangest part is that it does not even work after a reboot sometimes.
Like right now, when I got to services, QEMU guest agent is not running. Even though it has Automatically as startup option. I can start it manually, no problem.
Windows is 25H2
QEMU is 0.1.285

I am not knowledgeable enough to use the right filters or knowing where to look. That is why was not able to find anything. Do you know where I should be looking? The linked powershell commands in the other thread did not find anything noticeable. My behavior is also slightly different, since I don't lose network conneciton.
