Hardware Transcoding with Intel UHD Graphics 605 on Proxmox Privileged LXC

[Fate]

Thanks for the reply

Did you pass the GPU into the LXC?

Yeah, I'm pretty sure I did at least. I added the following lines to my LXC.conf:

Code:

lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.hook.pre-start: sh -c "chown 0:104 /dev/dri/renderD128"

which contains variables (226:0, 226:128 ) based on the output of "ls -la /dev/dri" run on the proxmox host

Code:

total 0
drwxr-xr-x  3 root root        100 Aug 25 04:32 .
drwxr-xr-x 20 root root      4780 Aug 25 04:50 ..
drwxr-xr-x  2 root root        80 Aug 25 04:32 by-path
crw-rw----  1 root video  226,  0 Aug 25 04:32 card0
crw-rw----  1 root render 226, 128 Aug 25 04:32 renderD128

I've tried changing the 104 in "chown 0:104 /dev/dri/renderD128" to 106 as well, to cover the render getent group in both Proxmox host as well as LXC guest.

On my proxmox:

Code:

root@pvx:/dev/dri# ls -lh
total 0
drwxr-xr-x 2 root root        80 Jun  5 00:03 by-path
crw-rw---- 1 root video  226,  0 Jun  5 00:03 card0
crw-rw---- 1 root render 226, 128 Jun  5 00:03 renderD128

on my lxc:

Code:

[root@kuroko dri]# ls -lh
total 0
drwxr-xr-x 2 root root        80 Jun  5 00:03 by-path
crw-rw---- 1 root video  226,  0 Jun  5 00:03 card0
crw-rw---- 1 root render 226, 128 Jun  5 00:03 renderD128

Looking at your log earlier it seems to mismatch your proxmox side, so I'm pretty sure this is your issue.

Could you spawn a test container with tteck scrit and compare how the script mounts your devices?

Just to make sure can oyu post
dmesg | grep i915 on proxmox side?
