* New features

  * nodedev: Add ability to automatically start mediated devices

    The autostart status of a persistent mediated devices can be managed with
    the new APIs ``virNodeDeviceSetAutostart()`` and
    ``virNodeDeviceGetAutostart()``. The corresponding virsh command is
    ``nodedev-autostart``. In addition, two new APIs were added to get
    additional information about node devices: ``virNodeDeviceIsPersistent()``
    checks whether the device is persistently defined, and
    ``virNodeDeviceIsActive()`` checks whether the node device is currently
    active. This information can also be retrieved with the new virsh command
    ``nodedev-info``.

Enjoy.
