I am running Unraid v6.9.2 running on a Threadripper 1920X. I have a Windows 10 VM configured to pass through an Nvidia GTX 1660 Super and a USB 3.0 add in card. This setup has worked great for about 2 years. Most recently the array and the VM had been up for about 50 days. I went to work yesterday and when I came home the VM wasn't running. When I check the VMs section in Unraid it shows the VM as being paused.
The Windows environment in the VM is configured to be always on, not to sleep or hibernate or anything like that. I have no idea what caused it to pause. Now I can't get it to resume. When I try to resume the little status indicator icon spins for a split second and then goes right back to pause. If I force stop the VM and then start it again it appears to start up normally but a few seconds after the I get to the desktop everything freezes up. After that, when I check the status of the VM in Unraid again it shows as paused and will not resume. I don't know what caused this to happen out of the blue. I am attaching a diagnostic zip and a copy of the VMs xml config. Foolishly, I rebooted the server thinking it might help so I hope nothing was lost that can shed light on what's going on.
