Preparing VFIO pass-through devices
On the host, the host resources of a VFIO pass-through device must be controlled by a VFIO device driver.
For pass-through DASD and pass-through cryptographic adapter resources, you must also create and configure a VFIO mediated device.Note: VFIO
pass-through devices can block live migration of a virtual server,
