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!
