The end goal is to have a GPU to passthrough to multiple LXC containers. I originally had it mounted as a passthrough to a VM, but have since removed those configurations and want to use the LXCs instead. The primary objective is for my Jellyfin LXC to be able to utilise the GPU for hardware encoding.
Stats:
Proxmox VE 8.2.4 (6.8.8-3-pve)
i5-10400 CPU (not using the integrated graphics)
Nvidia Quadro P400
(Jellyfin LXC Unprivileged from Helper-Scripts)
Context:
I have followed quite a few guides, and each one seemed to have a failure somewhere for me - I suspect this may be the issue. I've installed packages to get the GPU to work such as:
I have removed, and purged the above packages, along with any associated packages, but this error still presents itself when trying to use the installer.
Current Situation:
I thought I had made some good progress, re-installing drivers via apt after many purges and reboots - the GPU seemed to be mounted, and under lspci I was getting the "Kernel driver in use: nvidia" under my GPU. I thought I was sorted, so I successfully (so I thought) passed through the GPU to the Jellyfin LXC (following this video guide), set Jellyfin to NVENC Hardware Acceleration, only to try and get a playback error essentially telling me that "no CUDA-capable device is detected".
I went back to my host, and ran the 'nvidia-smi' command, only to see that the whilst the GPU is identified, no processes are running like in every other screenshot I see in guides:
My Question:
Where do I go from here? Is there a way to clean out all the nvidia drivers from proxmox, so I can run the installer that many other users seem to have no issues with?
Have I potentially caused too much mess in my proxmox with all the packages and may need to clean install? Can I wait for a new proxmox update, and allow that new kernel to clean out any packages?
Apologies for the long post and fairly vague questions - I have spent many evenings on this, I feel that I have made this far more complicated for myself and I'm at the edge of my knowledge and fear that any further messing about could put my proxmox install in a bad state.
