This is a short and sweet howto on building a LXC Container on Proxmox and passing through a 5070 Ti GPU to it.
# Header
First we will be installing Proxmox NVIDIA drivers on the host itself, so that later we can amp the GPU to LXC containers that will have GPU passthgough configured.
ΒΆ Proxmox NVidia Drivers
- Install dependencies and update the initial ram fs.
sudo apt install g++ freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libglu1-mesa-dev libfreeimage-dev libglfw3-dev wget htop btop nvtop nano glances git pciutils cmake curl libcurl4-openssl-dev pve-headers-$(uname -r) dkms make pkg-config libglvnd-dev -y && update-initramfs -u
- Blacklist the nouveau drivers
cat >/etc/modprobe.d/blacklist-nouveau.conf <<'EOF'
blacklist nouveau
options nouveau modeset=0
EOF
- Reboot the host
reboot
- Download the NVidia drivers
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/580.126.18/NVIDIA-Linux-x86_64-580.126.18.run
- Make the file executable
chmod 755 NVIDIA-Linux-x86_64-580.126.18.run
- Run the installer with DKMS (Dynamic Kernel Module Support) option. Select the MIT/GPL Drivers!
./NVIDIA-Linux-x86_64-580.126.18.run --dkms
After the drivers are installed on Proxmox, we can create an LXC and configure it for GPU Passthrough.
- Add your GPU passthrough devices
- /dev/nvidia0
- /dev/nvidiactl
- /dev/nvidia-uvm
- /dev/nvidia-uvm-tools
- /dev/nvidia-caps/nvidia-cap1
- /dev/nvidia-caps/nvidia-cap2
- Start your container
- Install a few needed packages
apt update && apt full-upgrade
apt install curl
apt install nvtop
apt install zstd
apt install jq
- Push the driver from the main proxmox host to the container (They need to be the same)
pct push 211 NVIDIA-Linux-x86_64-580.126.18.run /root/NVIDIA-Linux-x86_64-580.126.18.run
- Login to the container, make the file executable and run it without kernel modules (MIT/GPL Version)
chmod 755 NVIDIA-Linux-x86_64-580.126.18.run
./NVIDIA-Linux-x86_64-580.126.18.run --no-kernel-modules
- Run nvidia-smi and you will see something similar
