Device / Exporting Objects}

+When an object created by one virtio device needs to be
+shared with a seperate virtio device, the first device can
+export the object by generating a \field{uuid} which the
+guest can pass to the second device to identify the object.
+
+What constitutes an object, how to export objects, and
+how to import objects are defined by the individual device
+types. The generation method of a \field{uuid} is dependent
+upon the implementation of the exporting device.
+
+Whether a particular exported object can be imported into
+a device is dependent upon the implementations of the exporting
+and importing devices. Generally speaking, the guest should
+have some knowledge of the host configuration before trying to
+use exported objects.
