Bug Description

The libvirt node device driver is currently not aware of the vfio-ap matrix device. As a consequence it's not possible to use libvirts' mediated device management recently introduced in the node device driver. For a non-expert user to identify matrix assigned ap devices that can be used for mediated device management can be a burden. Presenting these ap devices available in the host organized in the node device tree according to their assignment to either the matrix device or the computer system correctly would lower or even remove the burden.

With the node device support the passthrough of crypto devices will be enabled and simplified with libvirt >=6.9.0.
