Hi Is there any way to get events dispatching in synchronous mode ? I mean I'm running my own events polling loop which calls virEventRunDefaultImpl each turn . I'd expect to get my callback function called synchronously , but it's not . Seems that's async call. Maybe it's my general misunderstanding and I shouldn't use virEventRunDefaultImpl for that ? Thanks in advance for any guidance Krzysztof ------------------------...

...nect, Before usr old virConnectPtr , I call virConnectIsAlive. but when I restart libvirtd , virConnectIsAlive return 1, and I continue other operate use the old virConnectPtr, program will receive signal pipe. I use libvirt event. before any api use, I call virEventRegisterDefaultImpl, and run virEventRunDefaultImpl. then use virConnectIsAlive, when I restart libvirtd, virConnectIsAlive will return 0, I want know how to use virConnectIsAlive， if virConnectIsAlive use keep alive message, what default the interval and count. Thanks

good day to all. i still have not solved my problem with event handling. currently i have following code void libvirt_eventloop_thr_func() { while(true) //TODO: stop somehow on exit { if(virEventRunDefaultImpl() < 0) { virErrorPtr err = virGetLastError(); fprintf(stderr, "Failed to run event loop: %s\n", err && err->message ? err->message : "Unknown error"); } } } ... virSetErrorFunc(NULL, libvirt_error_handler); libvirt_connection = virConnectOpen(&...
