+ When a guest is running and interface of type <code>network</code>
+ may include a <code>portid</code> attribute. This provides the UUID
+ of an associated virNetworkPortPtr object that records the association
+ between the domain interface and the network. This attribute is
+ read-only since port objects are create and deleted automatically
