Hi Jim, I don't see any calls to libxl_event_dispose in libvirt.git, libxl_event.h says in relation to the event_occurs callback: * event becomes owned by the application and must be freed, either * by event_occurs or later. so does this mean the memory referenced by event is leaked by libxlEventHandler? libxl_event only contains dynamic allocations for LIBXL_EVENT_TYPE_DISK_EJECT which you don't seem to register for so the issue is probably benign but worth noting I think.
