Configuring VFIO devices
The VFIO framework can give guests direct access to specific host devices.
On the host, these VFIO pass-through devices are set up to be controlled by device-specific VFIO device drivers instead of their default device drivers. Depending on the device type, VFIO pass-through devices might require a VFIO mediated device that is based on host resources.
Note: VFIO pass-through devices can block live migration of a virtual server, see VFIO pass-through devices.
