[Libvirt-cim] question of DestinationSystem meaning in MigrateVirtualSystemToSystem method

Hi, I'm a little confusing of MigrateVirtualSystemToSystem method，who can tell me what does "DestinationSystem" refer to? It different from DestinationHost which can be passed by a simple ip address. As a reference, the DestinationSystem's Name have to be parsed below. Then what on earth does it mean? if (cu_get_str_path(dsys, "Name", &dname) != CMPI_RC_OK) { cu_statusf(_BROKER, &s, CMPI_RC_ERR_FAILED, "Missing key (Name) in DestinationSystem"); METHOD_RETURN(results, 1); return s; } Thanks!
