Hey all,

 

I've been playing GPU pass-through the last few days to my unraid server with a 3070.  I can only get GPU passthrough to work when I'm using seaBIOS.  I managed to get it working with windows 10 but I'd like to setup a windows 11 gaming VM.  Is it possible to get a Windows 11 VM with GPU passthrough working on my system using seasBIOS?

As per requirements Win11 needs UEFI and TPM, but you can either change registry values during install or patch the iso to bypass those.

Passthrough should work in UEFI though, the host system should be booting UEFI too.

I've been playing around with it for a few days now and have only got a black screen us TPM.  I figured out it was the BIOS by getting a linux vm (pop os) running using seaBIOS.  The a W10 VM running with passthrough again with seaBIOS>

 

Could it have something to do with my host bios settings?  I'm using an older motherboard,  SABERTOOTH Z97 MARK 1  with  4790k.

My experience is if the host had an opportunity to touch the GPU on boot, either the UEFI or bios implementation of the GPU vbios is "tainted" and only the other one will work. Some people have luck using a vbios dump to work around this, I never have. But there are options to block most of the GPU drivers (including really simply ones like vesafb) from loading which have helped me in the past.
