+  * qemu: automatic selection/binding of VFIO variant drivers
+
+    When a device is assigned to a guest using VFIO with ``<hostdev
+    managed='yes'>``, libvirt will now search the running kernel's
+    modules.alias file for the most specific match to that device for
+    a VFIO driver, and bind that driver to the device rather than
+    vfio-pci. A specific driver can also be forced, using the
+    ``<driver model='plugh'/>`` attribute.
