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.
