ovcrash Posted January 12, 2018 Share Posted January 12, 2018 Hi, I have setup a Windows 10 VM. I want to pass my GPU to that VM, i'm using the onboard GPU for unraid and a AMD Radeon HD for the VM. I can select the GPU for my Windows VM but the screen only stays black, nothing is showing on it. If i add a VNC screen on my VM i can see the Windows booting without errors and in the device manager the AM Radeon is there and installed correctly. So what else is missing for this to work? here is the xml of my vm. <domain type='kvm'> <name>W10_3</name> <uuid>33ba5b42-2737-381b-b483-51200ff5db80</uuid> <metadata> <vmtemplate xmlns="unraid"

thomas Posted January 18, 2018 Share Posted January 18, 2018 Use SeaBIOS instead of OVMF for the VM and it should work. Your AMD doesn't have UEFI support, for OVMF use, though you might find some patched BIOSes on the internet if you want to pass the ROM file... Quote Link to comment
