Host setup for VFIO pass-through devices
You must ensure that a VFIO device driver controls the resource on the host.
About this task
The VFIO device driver reserves the pass-through device for KVM guests and accesses the corresponding host resource on behalf of the guest.
Procedure
Although the details differ considerably by device type, the following main steps apply to all VFIO pass-through devices:
- Free the resource from control of the default device driver.
- Associate the resource with the corresponding VFIO device driver.
