+
+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 UUID which can then
+be passed 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. It is RECOMMENDED that devices generate version 4
+UUIDs as specified by \hyperref[intro:rfc4122]{[RFC4122]}.
