UHD 770 SR-IOV for guest VM
Ive got an Unraid 7.0 server running on an Alder-Lake i5-12500. I recently learned that the UHD 770 iGPU should support virtualization via the SR-IOV functionality and allow hardware acceleration in a guest VM.
I installed the Unraid Plugin (i915 SR-IOV by giganode) and set all the appropriate BIOS features. I set the desired VFs to 1 in the plugin and the plugin shows 1 VF created. I am able to select this as the GPU for any of my VMs, and as far as I can tell, the host side setup is correct and working.
I have tried several different guest VM operating systems including Lubuntu 26, Lubuntu 24, and Ubuntu 24. I have been troubleshooting the setup with ChatGPT and Gemini and from what I can tell, the gpu backed Xorg session never properly starts because the i915-sriov-dkms driver doesnt have a physical connector and Xorg crashes out.
I've spend days trying to get this to work and have not had any luck. Has anyone successfully used a SR-IOV VF as the GPU for a VM in unraid? If so, what guest OS? I haven't found many guides for this type of thing, maybe its not possible.

I helped somone fix a similar issue a few months ago. Newest bios fixed that issue. Is your bios fully up to date?
