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("qemu:///system");
Move this line ^^^ ...
if (virEventRegisterDefaultImpl() < 0) { virErrorPtr err = virGetLastError(); fprintf(stderr, "Failed to register event implementation: %s\n", err && err->message ? err->message: "Unknown error"); return -1; } { int callback = virConnectDomainEventRegisterAny(libvirt_connection, NULL, VIR_DOMAIN_EVENT_ID_LIFECYCLE, VIR_DOMAIN_EVENT_CALLBACK(domain_event_handler), NULL, NULL); if(callback == -1) { std::cout<<"Error: failed to register domain event handle callback\n"; return -1; } }
boost::thread(boost::bind(&libvirt_eventloop_thr_func));
... over here. The virConnectOpen detects if there's an even loop registered. And in your case you don't have any registered when calling it. Michal
