Intel UHD 750 passthrough windows

[NasKaya]

Hey,

 

maybe someone here can help me. Im still new to Unraid, so i dont have the deep knowledge to get everything running.

So i want to give my Windows 10 VM the GPU from my i9 11900k. Its the UHD 750. 

I was able to list the GPU with some comment in the sysconfig. And also configured unraid to run headless.

I also checked the GPU under system devices. I will put a screenshot at the end. 

 

Then i selected the GPU for the VM in the settings alongside the normal VNC.

I was able to install the intel driver. Windows know is showing the GPU inside device manager but with the error 43.

I cant find a solution to fix the error 43. So i also dont get any output via hdmi.

I dont have and docker app running. So docker cant use the GPU.

 

Maybe someone can help

I figured I would pile on to this thread since it's basically the same problem.

 

NEW to Unraid user this week after much research and new build to replace my aging Windows Server 2012R2 Essentials set up. 

I'm technical-enough, but not an IT professional and have only very limited (tooling around) linux experience.  Please be gentle!!  (but I'm happy to provide additional context or necessary information if I can)

 

Anyway, core elements of my build pertinent to this question are:

• Asus TUF Gaming B560M-PLUS WIFI mob
• Core i7-11700k CPU with UHD 750
• GPU - NVidia P620

 

Core objectives of the build outside of NAS are:

• Set up Win 10/11 VM to be my primary PC (Displaying on PC monitors and Audio outputs like a 'real' PC not just accessible over VNC)
• Plex (VM), HomeAssistant & Channels DVR through dockers 

My going in assumption (open to feedback) was that I think it makes most sense to me to have the Win 10/11 VM use the UHD 750 for display / GPU (not really much GPU needs on my PC - merely just to get a physical display and sound outputs) and leave the P620 to be assigned as the Unraid as primary GPU and potentially used for PLEX HW transcoding (or maybe Channels too... not sure how that works if multiple dockers need to access use a GPU...).  I have my BIOS setting for primary display set to PCIe to prefer the P620.  

 

Anyway, after reading various passthrough set up guides, I have the UHD750 and Intel (Tiger Lake-H) Audio set up as bound to VFIO at boot on the System Information settings and then successfully passed into the VM (I can see this in Device Manager when I set up both VNC and the UHD 750 as graphics cards.  if I only use the UHD 750 as graphics, I have no display but the VM does not error out and starts - just no display out the UHD750 HDMI).   However, in DevMgr I get the ERROR 43 and "Windows has shut down this device" info... and no output from the HDMI obviously.

 

If I click on the VM's logs it just opens a new window and circles forever.  It never actually shows any logs.   

 

So my question is:   Has anyone gotten UHD 750 properly passed though to a Windows VM? 

--> If so, were there initially issues? 

--> if so, what worked to resolve?   

 

Any other ideas I should try next?   I didn't want to get into editing the xml without specific guidance.

 

Thanks in advance to anyone who takes the time to weigh in here.

 

Happy to provide additional information to anyone as needed.

Also an Unraid noobie attempting to get an UHD 770 passed through from a 12900k. I have no clue where to even start.

Hm, are there any news on this? 

 

Have the same issue, can't passthrough the iGPU Intel UHD 750 to a WinVM.
