With recent additions to the node device xml schema, an xml schema can now describe a mdev device sufficiently for libvirt to create and start the device using the mdevctl utility. Note that some of the the configuration for a mediated device must be passed to mdevctl as a JSON-formatted file. In order to avoid creating and cleaning up temporary files, the JSON is instead fed to stdin and we pass the filename /dev/stdin to mdevctl. While this may not be portable, neither are mediated devices, so I don't believe it should cause any problems.
