When a host is rebooted, any mediated devices that were previously
configured will disappear. There have been requests for libvirt to
handle persisting these mediated devices across reboots, but the
decision was made that this should be handled at a lower level. mdevctl
is a new tool that handles registration and persistence of mediated
devices. If desired, mdevctl can automatically start these mediated
devices when the parent device becomes available.
Since mdevctl is the recommended solution for handling persistent
mediated devices, point users there when they encounter an error for a
missing mediated device.

NOTE:
- previous patch which attempted to start missing devices using mdevctl has
been withdrawn.
