GPU passthrough, also known as GPU virtualization, is a feature that allows a virtual machine (VM) to access and use the graphics processing unit (GPU) of a physical server for tasks that require high-performance graphics processing. This can be useful for running resource-intensive workloads, such as gaming, graphics rendering, and scientific simulations, that require a dedicated GPU.
Proxmox is a virtualization platform that supports GPU passthrough, and it provides a range of features and tools that can be used to set up and configure GPU passthrough for VMs. To use GPU passthrough with Proxmox, you will need a physical server with a compatible GPU, and you will need to configure the VM and the host server to support GPU passthrough.
To set up GPU passthrough with Proxmox, you will need to follow a few steps, including:
- Enable IOMMU (Input/Output Memory Management Unit) in the host server’s BIOS or UEFI settings.
- Configure the VM to support GPU passthrough. This may involve setting specific CPU and memory requirements, and attaching a PCI device to the VM.
- Configure the host server to pass the GPU to the VM. This may involve modifying the host server’s configuration files and using the Proxmox command-line interface (CLI) to assign the GPU to the VM.
GPU passthrough can be a useful feature for running resource-intensive workloads on Proxmox, but it requires careful configuration and setup to work properly. It is recommended to follow the documentation and guidelines provided by Proxmox and your hardware vendor when setting up GPU passthrough.
