## What it is
A guide and set of libvirt/QEMU hook scripts for passing a single GPU through to a virtual machine on Linux using VFIO, without needing a second GPU for the host. It walks through configuring libvirt/virt-manager to detach the GPU from the host and reattach it when the VM shuts down.

## Use cases
- run Windows games in a VM with full GPU performance on a Linux host
- pass my only GPU to a KVM virtual machine
- set up single GPU passthrough with virt-manager
- avoid dual booting between Linux and Windows for gaming
- rebind the GPU back to the host after a VM shuts down
- use VFIO on a Mini-ITX build with no integrated graphics

## When to choose
- you have exactly one GPU and want near-native VM graphics performance on Linux
- you use libvirt/virt-manager and want a proven hook-based setup
- you want to replace dual booting with a VM workflow

## When to avoid
- you have two or more GPUs and can use a simpler static passthrough setup
- you need the GPU available to the host and VM simultaneously
- your hardware or drivers lack proper IOMMU/VFIO support
- you need a guaranteed, supported solution - the guide explicitly offers no warranties
