Adding a Desktop Environment with Shared GPU Passthrough in Proxmox LXC (Xubuntu, Vulkan & VA-API)
In this video I will show you how to create an LXC Container that has a Desktop Environment and also have your Intel GPU fully working and still being shared between LXC Containers. As the problem with having a VM is that it takes full control over a GPU leaving LXC Containers unable to utilize your graphics card.
The guide is for Intel GPU’s, it can work with AMD or NVIDIA GPU’s, but you need to research/find the correct lines to pass-through in your LXC Configuration (Basically the step from 2:27, you basically don’t follow that along with other intel instructions and find the GPU’s counterpart instructions equivalent to it). If you have any questions please feel free to leave a comment. You could also use ChatGPT to troubleshoot other issues, as I have also used it when I am stuck at specific step.
