Nvidia GPU not detected inside Jellyfin container - beckettloose - 2025-11-10
Hello all,
I'm in the process of setting up GPU transcoding for my Jellyfin server, but I'm running into an annoying issue at the moment. This is my current setup for reference:
Host:
- Chassis: Dell R720xd
- CPU: 2x Intel Xeon E5-2680 v2
- RAM: 320GB ECC Memory
- Hypervisor OS: Proxmox VE 9.0.11
- GPU: Nvidia Quadro P2000
VM Specs:
- CPU: 4 cores
- RAM: 8gb
- OS: Ubuntu 25.04 Server
- Nvidia Drivers: 535.274.02
- Nvidia Container Toolkit: 1.18.0-1
Jellyfin playback fails whenever transcode is required, which appears to be caused by an issue with passing through the GPU from the VM to the container. In my troubleshooting, I started by checking the output of nvidia-smi on the vm itself and inside the container:
nvidia-smi run from VM:
