In my system i have the following specs:
CPU:FX-8350

RAM:16GB DDR3 @1866

Motherboard: MSI 970 Gaming

GPU#1: Quadro fx1800 (unraid command line)

GPU#2: Quadro fx3800

 

What i am trying to figure out is:
Why do i get a display output when i use SeaBios with my Windows 10 VM, but do i not get this using OVMF?

GPU config:

I have tried:
Using Custom ROM (https://www.techpowerup.com/vgabios/?did=10DE-05FF-10DE-0661)

rebooting server

 

Does anyone have an idea how i can fix this?
I really need to get OVMF with gou passtrough working because of the XML arguments that i want to use.

Greetings, Max

 

Also something i think might be important to tell: the server itself is on legacy mode. I do not know if changing this will make the server unbootable?

I'm no expert but I think that your GPU / BIOS need to be UEFI compatible to use OVMF. the FX3800 bios you linked to says: UEFI Supported: No

Oh, thanks! I have now got 2 GPU's wich i think do have UEFI support:  NVIDIA GT730 and a Readeon 7 240. ill put those in tonight

 

Do i not have to change the bios?

I have a Nvidia Quadro K2000 which I pass through to a Windows 10 VM with OVMF bios and it's working fine. 

 

I have not specified any additional bios in the VM settings. 

I got it working now! i changed it and it started working right away, altough the resolution is buggy, i've discovered this is because of my cable between the GPU and my monitor (DVI to VGA). I will replace this probably. I am now running with:
GPU#1: Quadro FX1800 (unraid console)

GPU#2: Nvidia GT730 (OVMF GPU)

 

Thanks for the help, i would have never thought about it actually haha
