How to do PCI-E/GPU Passthrough in Proxmox | IOMMU Groups Explained

In this video, you will learn how to do PCIe/GPU Passthrough in Proxmox. The IOMMU Groups are also explained properly along with the PCIe ACS Override feature. But what is GPU Passthrough? So, GPU Passthrough is the process of presenting the GPU present on the host system to the virtual machine as if it was present physically in the virtual machine.

We can use the gpu or any other pci-e device in any vm we want. So, for example, We can create a windows vm in proxmox and can pass through an external gpu present like nvidia or amd, or we can pass through the integrated graphics to that vm. This will enable hardware accelerated rendering for the desktop or playing games and you can perform compute tasks like video rendering, 3d modeling etc. as if you are doing it on a physical machine.

Similarly, in a linux headless vm, you can use the gpu for tasks like AI object detection like frigate or running your self hosted AI with models like llama3 locally on your vm. We can even use devices like pci-e coral tpu to accelerate AI object detection tasks using tensorflow in frigate.
