good day. i trying to make callback function for VIR_DOMAIN_EVENT_ID_LIFECYCLE, i have successfully registering callback, but it never called, i need to know when domain started, stopped or crashed, i have write following code
static int domain_event_handler(virConnectPtr conn, virDomainPtr dom, int event, int detail, void * opaque) { switch(event) { } return 0; }
..... 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; } .....
but "domain_event_handler" is never called, what is wrong here ?
Are you running an event loop? You can have a look at our examples [1] and see what's being done there. Especially note the virEventRunDefaultImpl() [2] there.

oh..., i missed it, thx for hint and sorry for stupid questions .
now it's working except for events from other connections, for example i want to handle domain started by virt-manager, now i do not have event when it's started, is exists any api to handle this events, or i need to implement internal polling of domains state in my application ?
The events system reports all lifecycle events, regardless of which connection triggered them. If you're not seeing events from domains started by virt-manager then your almost certainly connecting to a different libvirt URI than virt-manager is using.
