maxstevens2 Posted May 9, 2019 Share Posted May 9, 2019 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 Quote Link to comment
maxstevens2 Posted May 9, 2019 Author Share Posted May 9, 2019 (edited) 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? Edited May 9, 2019 by maxstevens2 Quote Link to comment
Mex Posted May 10, 2019 Share Posted May 10, 2019 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 Quote Link to comment

Mex Posted May 10, 2019 Share Posted May 10, 2019 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. Quote Link to comment
maxstevens2 Posted May 10, 2019 Author Share Posted May 10, 2019 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 Quote Link to comment
