Proxmox LXC iGPU passthrough​

I couldn't find any tutorial that worked out for me so i create my own.
Code was executed at Lenovo M720q, i5-8500T, Proxmox 8.1.3


Full step by step guide for passthrough intel iGPU for jellyfin and Intel CPU's gen7+
It seems like Firefox has some problems with transcoding movies. It’s recommended to stick with chromium based browsers.

Install the required drivers on the Proxmox host.​

apt install -y intel-opencl-icd

Edit grub

nano /etc/default/grub

Find the line that starts with GRUB_CMDLINE_LINUX_DEFAULT and change to following:

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on i915.enable_gvt=1"

Execute command:

update-grub

reboot host​

Validate changes. It showed IOMMU enabled

dmesg | grep -e DMAR -e IOMMU

Edit etc modules

nano /etc/modules

    # Modules required for PCI passthrough
    vfio
    vfio_iommu_type1
    vfio_pci
    vfio_virqfd
    # Modules required for Intel GVT
    kvmgt
    exngt
    Vfio-mdev

Execute command:

update-initramfs -u -k all

Your VGA card should be visible with command

lspci -nnv | grep VGA

Enable GUC

echo "options i915 enable_guc=3" >> /etc/modprobe.d/i915.conf

Create LXC container as plivilaged and add parameters to configuration

nano /etc/pve/lxc/<container number>.conf

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

On LXC container


Update and upgrade system

apt update && apt upgrade -y

Install ffmpeg

apt install ffmpeg -y

Install software-properties-common

apt-get install software-properties-common -y

Install curl and gnupg

apt install curl gnupg -y

On Ubuntu (and derivatives) only, enable the Universe repository to obtain all the FFmpeg dependencies

add-apt-repository universe

Download the GPG signing key (signed by the Jellyfin Team) and install it

mkdir -p /etc/apt/keyrings
curl -fsSL <https://repo.jellyfin.org/jellyfin_team.gpg.key> | sudo gpg --dearmor -o /etc/apt/keyrings/jellyfin.gpg

Add a repository configuration at

/etc/apt/sources.list.d/jellyfin.source

export VERSION_OS="$( awk -F'=' '/^ID=/{ print $NF }' /etc/os-release )"
export VERSION_CODENAME="$( awk -F'=' '/^VERSION_CODENAME=/{ print $NF }' /etc/os-release )"
export DPKG_ARCHITECTURE="$( dpkg --print-architecture )"
cat <<EOF | tee /etc/apt/sources.list.d/jellyfin.sources
Types: deb
URIs: <https://repo.jellyfin.org/${VERSION_OS}>
Suites: ${VERSION_CODENAME}
Components: main
Architectures: ${DPKG_ARCHITECTURE}
Signed-By: /etc/apt/keyrings/jellyfin.gpg
EOF

Update your APT repositorie

apt update

Install the Jellyfin metapackage, which will automatically fetch the various sub-packages:

apt install jellyfin -y

Add user jellyfin to needed groups

usermod -a -G video jellyfin
usermod -a -G render jellyfin
usermod -a -G input jellyfin
usermod -a -G ssl-cert jellyfin

install ffmpeg for jellyfin because for some reason jellyfin ffmpeg doesn't install with in jellyfin install with cause error trying to transcode HEVC

apt install jellyfin-ffmpeg -y

these are setting for transcoding in jellyfin (i5-8500T)

Can you please get in more details after the On Ubuntu (and derivatives) only, enable the Universe repository to obtain all the FFmpeg dependencies?

after executing sudo gpg --dearmor -o /etc/apt/keyrings/jellyfin.gpg nothing happens.

Great! Thanks so much! I spent hours trying to find a working solution!
