iJumbo Posted November 8, 2019 Share Posted November 8, 2019 Hello I tried to passthrough my R9 290 with Threadripper 1950x (Motherboard: Asus Prime x399-a Updated to the last BIOS) without success. The passthrough works with SeaBIOS but not with OVMF. Things i tried: Editing the flash options adding video=efifb:off allow_unsafe_interrupts=1 vfio-pci.ids=card id, sound card id vfio-stub.ids=card id, sound card id Dumping the vbios and using it in the passthrough configuration The GPU is in the first slot of the motherboard and is the only card i have installed. The only thing that the screen does when i start the VM is turning black with no signal. Someone can help? Thanks Quote Link to comment
bastl Posted November 8, 2019 Share Posted November 8, 2019 @iJumbo Did you tried to set the machine type of the VM to Q35? Some users with AMD passthrough issues had success with this. 1 hour ago, iJumbo said: The GPU is in the first slot of the motherboard and is the only card i have installed. Trying an different slot can also help or if you have an old GPU laying around use this in the first slot. Quote Link to comment

Macinabox Docker produces OVMF image, i tried with SeaBios but without a success boot. Also other images i have are all OVMF Quote Link to comment
