[solved] GPU driver problem

Gpu: AMD FirePro W7000


Hi guys, 


I have a strange problem with my Win 10 VM. It is running fine, but after I have installed the GPU driver it won't boot again. It just got stuck in Windows loading screen. (with no entry in eventvwr)

Windows does start in safe mode.

After removing the driver it is working again.


So I assume that there is something wrong with the driver, but I have no clue what since I tried a few different AMD driver versions. 

The GPU is many years old, maybe I should try installing an older driver?

No, I haven't bound it to VFIO, should I?

There is a green circle next to the checkbox which says "Kernel driver in use: vfio-pci"


To clarify: 

It does boot when AMD drivers are not installed in the Windows VM

It doesn't boot after the drivers have been installed


Do I need to configure anything else for "headless" unraid?

If you don't bind it, unRAID will use it for it's terminal output. Did you connect a monitor to the GPU to test this? As long as unRAID ist using the GPU, you can't use it in the VM. So your main target should be to boot unRAID gpu-less.

Okay, I will test it.

I had a monitor connected and it switched from unraid terminal output to the VM output after I have started the VM

(that is also what I would expect Unraid to do)


and then check the vfio entry for gpu in the VM form? Or is this not neccessary?

Seems to be working now. I have bound the GPU to VFIO and have restarted Unraid with no effect. 

After further research I read about similar problems with AMD GPUs and that it might be a solution to switch machine to Q35 and that worked. 


Everything is now fine I guess - many thanks mgutt
