Create a Render LXC in Proxmox

Instructions to setup a dedicated rendering LXC for Jellyfin. Useful for running Jellyfin in a VM and without passing through the whole iGPU, instead passing off to LXCs, allowing using more than one Proxmox host in the cluster for rendering.

Sources

• Jellyfin install: https://linuxcapable.com/how-to-install-jellyfin-media-server-on-ubuntu-linux/
• Jellyfin Intel GPU config: https://jellyfin.org/docs/general/post-install/transcoding/hardware-acceleration/intel#lxc-and-lxd-container
• Remote ffmpeg: https://github.com/joshuaboniface/rffmpeg?tab=readme-ov-file

Hardware

• Minisforum MS-01

Proxmox Steps

• Create a privileged LXC.
  • Ubuntu: bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/ubuntu.sh)"
  • Note: Privileged required in order to use NFS to mount data/cache directories from Jellyfin server.
• Add a Device Passthrough.
  • Device Path: /dev/dri/renderD128
  • GID (for Ubuntu 24.04): 993
  • Mode: 0660
• Reboot the LXC
