I think the problem is you're running an ancient libvirtd which doesn't 
understand any of tray change, pmwakeup, pmsuspend, balloonchange 
events. And in the way thaat the event-test demo program is written, it 
just closes the connection and exits. Try to build the libvirt from the 
sources and you should be all good again.

BTW: there's no need to build the event-test.c like that (but you can, 
if you want to). You can just:

     make -C examples/object-events/ event-test
