Hello!

I've been using Proxmox for a couple of months now. I want to try to remove the usage of my GTX 1660 super and use Intel quicksync and iGPU capabilities for my NVR and Plex.

I have 2 spare Dell Optiplex 7060, with an i5-8500T, with Virtualisation and VT-D enable. I've tried mutiple guide on how to passthrough the iGPU to a VM (which is a windows 11). No matters what I do, the VM see Intel UHD 630, but error code 43.

I tried blacklisting the driver, no black list, IOMMU is enable, VM is OVMF, pc-q35-10.0, UEFI enable, TPM, PCI device is assigned to the right ID... There is something I miss, or the computer is not able to pass normally the iGPU.

I tried multiple guide, from proxmox doc, from 3os.org and other, it is not working o_Oo_O.

I,ve been looking on proxmox forum, people having this issue, some fixed it, other not. What am I missing?

Any help is appreciated :)
 
Direct passthrough of Intel iGPU doesn't work on Proxmox VE 9.

Proxmox engineers have reproduced the issue but haven't found a solution.

You should wait for the outcome of the original thread rather than continuing the discussion in a new thread.

Thread 'updated to PVE 9.0 then GPU passthrough stopped working on Windows'

Previously the Intel 630 GPU passthrough is working fine on PVE 8 (for both Ubuntu and Windows 11).

Just now updated to 9.0, Windows - Device manager shows the device as error code 43. But if I passthrough the GPU to Ubuntu VM, it's working fine.

Checked these and verified the GPU should be successfully passed through (as Linux also can take that up)
