Intel i7-12700T vGPU Passthrough to Ubuntu - not working in Frigate?

[bawjaws]

Hi all,

I've just done a fresh install of Proxmox on new hardware. I have an Ubuntu 22.04 VM running on Proxmox, and have followed Derek Seaman's guide for passing through virtual GPUs to VMs.

That seems to be working on the Proxmox side, and in the Ubuntu VM I see:

00:01.0 VGA compatible controller: Device 1234:1111 (rev 02)
06:1b.0 VGA compatible controller: Intel Corporation AlderLake-S GT1 (rev 0c)

But in Frigate (which is running in docker on Ubuntu), I see lots of errors such as:

No VA display found for device /dev/dri/renderD128.
Failed to set value '/dev/dri/renderD128' for option 'qsv_device': Invalid argument

which suggest that there's a problem with the vGPU passthrough.
Wondering if anyone has come across this before or might know of a solution?

Kevin

Frigate runs best with docker installed on bare metal debian-based distributions. 
For ideal performance, Frigate needs access to underlying hardware for the Coral and GPU devices. 
Running Frigate in a VM on top of Proxmox, ESXi, Virtualbox, etc. is not recommended.

Thanks for replying - yeah I was aware of the advice but it's pretty common to run it in Proxmox - hence them including "but not in all cases" at the end of the paragraph you quoted. I had this working perfectly on the old i5-9500. I'm starting to think the issue lies in the Ubuntu VM not having sufficiently up-to-date i915 drivers for the vGPU.

I am having the same issue running on a Debian LXC. Interestingly I have emby running on an Ubuntu lxc that is working great with the passthough. I may try installing docker within an Ubuntu lxc. To see if that works like my Emby LXC. On a side note: I've had permission issues previously running hardware passthough in a VM. Make sure whatever user / group docker is running as has unix permissions to /dev//dri/renderD128

the last gen intel did change the technology used and over 11, the igpu cannot be pass. at least with current kernel. maybe next year if..
