Passthrough Graphics Card to VM - GUI Crash [Solved]

[Defylimits]

So I've got an interesting issue, if I assign a graphics card and then start the VM, my VM Manager seems to crash. When I click on the VMs tab or on VM Manager under settings both pages from the Unraid GUI it will not load, I also loose access to the Dashboard page which will not load correctly.

VM's already running still appear to be accessible when this is happening though and Dockers appear to be online? To get the system back working I need to reboot, but I can't do this from the graphics and have to go power off the server physically and then restart it that way.

I've got three graphics cards in my machine, a GT710 for Unraid, a Quadro P600 for Plex transcoding and the 1070 I'm looking at passing through to my VM.

I tried this on the Windows VM I had, just by changing from VNC graphics to the 1070 and experienced this crash a number of times, reseting back to VNC graphics and everything works fine. Looking something up I found it might be an issue running the OVMF BIOS, so I setup another Ubuntu machine with SeaBios, but just had the same issue.

Wondering if anyone has any ideas?


Btw hello again everyone, last time I was in the forum was back in March 2020, pandemic kept me away from home for some time so I didn't have a chance to fiddle and bugger anything else up until now!

Looking at the Syslog I have these errors around the time having the issue? Am I missing something?

Idiot, didn't Stub the graphics!

Tools >> System devices - Select IOMMU Group with Graphics card in and scroll to the bottom clicking "Bind Selected VFIO At Boot"
