## AI overview

This tutorial explains how Proxmox Resource Mappings can represent passthrough hardware as logical resources across cluster nodes. It contrasts this approach with assigning a VM a fixed PCI address, which may fail when the VM moves to a node where the device has a different address.

Many home labbers are starting to experiment with AI in the home lab and are using things like GPU passthrough on their Proxmox hosts. But passthrough is not just something... The post I Changed How I Do GPU Passthrough in Proxmox After Finding This Feature appeared first on Virtualization Howto.
