Hardware Acceleration with LXC on Proxmox Server

[Phreeak 3]

Hi Volks,

I don't know if there is already an article on this, at least I haven't found one.

I have a Proxmox server with an inbuilt Intel 630 GPU. I will show you here how you can activate the hardware acceleration for it. 

!! This is how it works for me. There are probably better ways, but this is the way it works for me  

I installed Emby with the LXC script from tteck (https://github.com/tteck) thanks for your work!

https://tteck.github.io/Proxmox/

If you install Emby via the script and are on the emby interface, you still have to make a few settings on Proxmox and the LXC container itself.

 

1. switch to your Proxmox instance and execute the following command:

nano /etc/modprobe.d/i915.conf

enter the following there:

options i915 enable_guc=3

and save the file.

 

2. reboot Proxmox

 

3. Still in the Proxmox instance, execute this command

nano /etc/pve/lxc/105.conf (You must adapt 105 to your LXC container!!)

Copy the following lines into the last position

lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.mount.entry: /dev/denderD128 dev/dri/renderD128 none bind,optional,create=file

save the file.

4. Still in the Proxmox shell, execute this command:

chmod -R 777 /dev/dri/*

5. Now switch to the shell of the Emby LXC container

add the Emby user to the groups:

usermod -aG video emby
usermod -aG input emby
usermod -aG render emby

6. Restart your emby server

And here you go!

This is a great guide and matches a Jellyfin one I've actually been using and that's reassuring.

My issue is that my emby is nested inside the LXC using docker, so far I can't work out how to pass the gpu through (i think it's Step 5 where I basically become stuck). Does anyone have any idea what I need to do to get this working for my set up?

Hi, can you explain more about where you think you're stuck?

Wonder if this is the same for someone with AMD Cpu and Nvidia GPU on a pcie

@cThumbs?

Assuming the "i915" used in the above config is referring to an intel driver, then no.

Thanks for following up.

Was checking if anyone knows how to make this command stick if proxmox resets. After a server reboot, I have to run this command line again to bring back hardware transcoding.
