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 the shell of the node
Check to see what kernel version you are running
uname -r
Install headers
apt-cache search pve-header
apt install pve-headers-*.*.*-*-pve
Blacklist Nouveau
nano /etc/modprobe.d/blacklist.conf
blacklist nouveau
update-initramfs -u
Reboot
Install Dependencies
apt install build-essential
Download Drivers
wget (YOURDRIVERS)
Nvidia driver site: https://www.nvidia.com/Download/index.aspx
Make driver file executable
chmod +x (YOURDRIVERFILE)
Install the drivers
./(YOURDRIVERFILE)
Make sure drivers load when restarted
nano /etc/modules-load.d/modules.conf
Add these lines
# Nvidia modules
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 that the drivers are running
nvidia-smi
Edit the conf container you want to passthrough too
nano /etc/pve/lxc/(YOURCONTAINERID).conf
Add these lines but make sure the path (numbers) are correct
ls -l /dev/nv*
# 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
apt update && apt upgrade -y
Download Drivers in the container this time
wget (YOURDRIVERS)
Nvidia driver site: https://www.nvidia.com/Download/index.aspx
Make driver file executable
chmod +x (YOURDRIVERFILE)
Run the drivers file with the extension
./(YOURDRIVERFILE) –no-kernel-module
Reboot
nvidia-smi
Install Plex
