I realized that I had 2 things wrong. 1. I was passing a vbios ROM to the VM while it was unnecessary. It prevented the driver from correctly installing and kept it @ 800x600 2. Even though I removed the vbios, the newest version of AMD Adrenaline drivers would still not install. I had to use a slightly older version (in this case, 2019-19.10.1 - Oct 17) and it installed fine.

I am able to boot correctly in Win10 but when I try to install the latest AMD GPU drivers, I am getting the attached error message. Previous AMD drivers were never installed on this VM, it's a fresh install. I tried for the sake of it to do this: But I am still getting this error. Any idea?

I tried it before and it would not boot using Q35. I just tried it again and IT WORKED! Wooo thank you so much. I think I didnt try it again since I updated my BIOS to version 4.50. Now I only passed 1 core and it seems ok, I'll try to bump it a little. Thanks again!

Interesting, and great to hear! Just for the sake of it I tried again and somehow I managed to go further this time. I got to Win10 recovery process, then restarted but now I'm stuck on the TianoCore logo, and the Win spinning dots are frozen. Cpu usage for the 1 core i'm passing is at 99% Here is my current XML configuration: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' id='9'> <name>Gaming W10</name>

I currently have the ASRock B450 Pro4 and it seems like unraid dosent play well with GPU Passthrough, I get those errors when trying to start a Win10 VM: qemu-system-x86_64: vfio_region_write(0000:0a:00.0:region0+0x9e198, 0xff000000ff000000,8) failed: Device or resource busy From what I read it seems to be related to AGESA, I am currently on version 1.0.06 Current specs: Ryzen 7 2700 ASRock B450 Pro4 (bios version 4.50) Sapphire RX580 I am considering selling this motherboard and getting one that is known to work properly. I will only be passing 1 GPU to VMs (maybe eventually another one for plex transcoding, but this is not a priority). What is the general concensus here on which make / model plays great with unraid and VFIO in general? Thanks!
