###What is VFIO? VFIO stands for Virtual Function I/O. VFIO is a device driver that is used to assign devices to virtual machines. One of the most common uses of vfio is setting up a virtual machine with full access to a dedicated GPU. This enables near-bare-metal gaming performance in a Windows VM, offering a great alternative to dual-booting.

###The Wiki The wiki will be a one-stop shop for all things related to VFIO. Right now it has links to a small amount of resources, but it will constantly be updated.
