albert / Passing a GPU through to a Proxmox container

We will pass a GPU through to a proxmox container and utilize it for video transcoding. In PVE Host shell `uname -r` - Install headers `apt install pve-headers` - Blacklist nouveau `nano /etc/modprobe.d/blacklist.conf` - Add lines `blacklist nouveau` - Update Initramfs `update-initramfs -u` - Reboot! - Install dependencies `apt install build-essential` - Download driver (https://www.nvidia.com/Download/index.aspx?lang=en-us) `wget {YOUR-DRIVER-URL)` - Make the driver file executable `chmod +x {YOUR-DRIVER-FILE}` - Install the driver `./{YOUR-DRIVER-FILE}` - Make sure the driver loads when restarted `nano /etc/modules-load.d/modules.conf` - Add lines ``` nvidia nvidia-modeset nvidia_uvm ``` - Update Initramfs `update-initramfs -u` - Create udev rules `nano /etc/udev/rules.d/70-nvidia.rules` - Add lines ``` KERNEL=="nvidia", RUN+="/bin/bash -c '/usr/bin/nvidia-smi -L && /bin/chmod 666 /dev/nvidia*'" KERNEL=="nvidia_modeset", RUN+="/bin/bash -c '/usr/bin/nvidia-modprobe -c0 -m && /bin/chmod 666 /dev/nvidia-modeset*'" KERNEL=="nvidia_uvm", RUN+="/bin/bash -c '/usr/bin/nvidia-modprobe -c0 -u && /bin/chmod 666 /dev/nvidia-uvm*'" ``` - Reboot! - Check if the driver is running `nvidia-smi` - Edit the container conf you want to passthrough to `nano /etc/pve/lxc/{YOUR-LXC-ID}.conf` - Note the output of this `ls -l /dev/nv*` - Add these lines but make sure the path (numbers) are correct ``` #Allow cgroup access lxc.cgroup2.devices.allow = c 195:0 rw lxc.cgroup2.devices.allow = c 195:255 rw lxc.cgroup2.devices.allow = c 195:254 rw lxc.cgroup2.devices.allow = c 509:0 rw lxc.cgroup2.devices.allow = c 509:1 rw lxc.cgroup2.devices.allow = c 10:144 rw #Pass through device files 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/nvram dev/nvram none bind,optional,create=file ``` - Start the container - In LXC shell `apt update && apt upgrade -y` - Download driver (https://www.nvidia.com/Download/index.aspx?lang=en-us) `wget {YOUR-DRIVER-URL)` - Make the driver file executable `chmod +x {YOUR-DRIVER-FILE}` - Install the driver `./{YOUR-DRIVER-FILE} --no-kernel-module` - Reboot! - See if the driver is working `nvidia-smi` ## Now you can install Jellyfin and use your nVidia GPU for transcoding.
