I'm probably missing something obvious, but I thought this could be
simply

  while (!quit) {
      g_mutex_lock(&eventLock);
      if (eventQuitFlag && !eventPreventQuitFlag) {
          quit = true;
          if (dom) {
              virDomainDestroy(dom);
          }
      }
      g_mutex_unlock(&eventLock);
      virEventRunDefaultImpl();
  }

Do we specifically want to avoid call virEventRunDefaultImpl() one
last time if the domain has failed to start?
