Intel iGPU SR-IOV woes

Hi, decided to get my hands dirty with virtualization and level up my “home lab”. To achieve this I treated myself to a 12900HK mini PC in hope to make use of the virtualization features offered by the Intel iGPU.
I installed Proxmox on the machine, installed the appropriate drivers following this guide and all seemed okay.

Up until today, when I thought that I couldn’t make use of the Intel iGPU in my VMs because I was installing the wrong drivers. During the MOK enroll of the guest i915 drivers (apparently you need a UEFI system to pass virtualized GPUs) the system did something extremely weird: the fan ramped up and for a moment I lost connection to the Proxmox web GUI.
I thought I had screwed it up, but after a reboot and deletion of the problematic VM I was working on everything seemed fine. I didn’t lose anything running on the machine.

I started going through the logs to see if anything really happened to the host OS and found this message:

kernel: xe 0000:00:02.7: Your graphics device 46a6 is not officially supported
by xe driver in this kernel version. To force Xe probe,
use xe.force_probe='46a6' and i915.force_probe='!46a6'
module parameters or CONFIG_DRM_XE_FORCE_PROBE='46a6' and
CONFIG_DRM_I915_FORCE_PROBE='!46a6' configuration options.

repeated for each of the instance of the GPU created by the i915 kernel module.

Now what I think happened is that installing the guest i915 kernel must’ve also made the guest OS crash because of this error I’m seeing.

And going back to this error: how do I solve it? Is it something I should be worried about? I’ve been searching non-stop and end up with 20 tabs open all the time to try and understand how to do things but I still can’t figure it out.

Thanks!

P.S Setup details:

  • Intel i9 12900HK (all the virtualization options enabled in BIOS)
  • Intel Iris Xe 96EU
  • Proxmox VE 8.3.3
  • Kernel 6.8.12-7-pve
  • Driver i915-sriov-dkms_2025.01.22
