Which other domain would you expect it to be? xen/incude/public/event_channel.h says: * EVTCHNOP_bind_interdomain: Construct an interdomain event channel between * the calling domain and <remote_dom>. <remote_dom,remote_port> must identify * a port that is unbound and marked as accepting bindings from the calling * domain. A fresh port is allocated in the calling domain and returned as * <local_port>. The important part being "between the calling domain".
