Help: Trying to set up Hardware Transcode (HW) Using my Nvidia GPU in a Plex LXC Container

[gingaranga]

Hello.

I am trying to get hw-transcoding setup for my Plex container in Proxmox 8. The following is the guide I followed:

1. Install dkms on the PVE host via

   apt-get install dkms

2. Install latest pve-headers:

   apt install pve-headers

3. Download and Install the proprietary NVIDIA drivers from the NVIDIA website on the PVE host and reboot. Verify correct installation using

   nvidia-smi

   . Use the following commands to download and install the drivers:

wget https://us.download.nvidia.com/XFree86/Linux-x86_64/535.104.05/NVIDIA-Linux-x86_64-535.104.05.run

chmod 777 ./NVIDIA-Linux-x86_64-535.104.05.run

./NVIDIA-Linux-x86_64-535.104.05.run --kernel-source-path /usr/src/linux-headers-6.2.16-12-pve

4.

• Stop your container. You need to modify your LXC container definition file using your favourite text editor to pass the NVIDIA /dev entries from the host to the LXC. If your LXC container ID is 100, then you edit /etc/pve/lxc/100.conf and add the following lines to the end of the file:

lxc.cgroup2.devices.allow: c 195:* rwm
lxc.cgroup2.devices.allow: c 509:* rwm
lxc.cgroup2.devices.allow: c 226:* rwm
lxc.mount.entry: /dev/nvidia0 dev/nvidia0 none bind,optional,create=file
lxc.mount.entry: /dev/nvidiactl dev/nvidiactl none bind,optional,create=file
lxc.mount.entry: /dev/nvidia-modeset dev/nvidia-modeset none bind,optional,create=file
lxc.mount.entry: /dev/nvidia-uvm dev/nvidia-uvm none bind,optional,create=file
lxc.mount.entry: /dev/nvidia-uvm-tools dev/nvidia-uvm-tools none bind,optional,create=file
lxc.mount.entry: /dev/dri dev/dri none bind,optional,create=dir lxc.mount.entry: /dev/fb0 dev/fb0 none bind,optional,create=file

5. Start your container.

6. Download and install the NVIDIA drivers from their website within the LXC container. When you run the downloaded installer file, use the switch

--no-kernel-module

:

wget https://us.download.nvidia.com/XFree86/Linux-x86_64/535.104.05/NVIDIA-Linux-x86_64-535.104.05.run

chmod 777 ./NVIDIA-Linux-x86_64-535.104.05.run

./NVIDIA-Linux-x86_64-535.104.05.run --no-kernel-module

7. After installation, stop and start the container. Then, within the container, run 'nvidia-smi' to verify everything works correctly.

I got to the point of setting up the drivers in the lxc container and verifying using

nvidia-smi

, but received the following error:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

I am not sure where I went wrong.

Please see the attached images for the questions and warnings during installation. I selected YES for all answers. Not sure if that caused any errors.
