what a correct use for virConnectDomainEventRegisterAny API, how to Obtain a stable expected result
...D ,
my process as follow:
cb_para->call_id=virConnectDomainEventRegisterAny(cb_para->conn,cb_para->dom,VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED, VIR_DOMAIN_EVENT_CALLBACK(vnf_control_del_network_cb), cb_para, vnf_control_del_network_cb_free);
flags |= VIR_DOMAIN_AFFECT_CONFIG;
if (virDomainIsActive(dom) == 1) {
flags |= VIR_DOMAIN_AFFECT_LIVE;
}
ret = virDomainDetachDeviceFlags(dom, xml, flags);
above code write in thread loop ,then in the same loop :
while (1) {
mission = vnf_mission_queue_get(task);
if (mission == NULL) {...

why virConnectDomainEventRegisterAny can't alway trigger the callback ,how can i get a stable callback ?
...llowing process:
int vnf_control_del_network(void *arg)
{
。。。。。
call_id = virConnectDomainEventRegisterAny(conn, dom, VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED, VIR_DOMAIN_EVENT_CALLBACK(vnf_control_del_network_cb), cb_para, vnf_control_del_network_cb_free);
flags |= VIR_DOMAIN_AFFECT_CONFIG;
if (virDomainIsActive(dom) == 1) {
flags |= VIR_DOMAIN_AFFECT_LIVE;
}
ret = virDomainDetachDeviceFlags(dom, xml, flags); // detach a nic from vm guest os
。。。。
}
void vnf_control_del_network_cb(virConnectPtr conn, virDomainPtr dom, const char *dev,void * opaque) //this callback can't al...

when virEventAddTimeout trigger timeout ,should in the callback call virConnectDomainEventDeregisterAny ?
...= conn;
cb_para->time_out = 20*1000;//20s
cb_para->call_id = virConnectDomainEventRegisterAny(conn, dom, VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED, VIR_DOMAIN_EVENT_CALLBACK(vnf_control_del_network_cb), cb_para, vnf_control_del_network_cb_free);
flags |= VIR_DOMAIN_AFFECT_CONFIG;
if (virDomainIsActive(dom) == 1) {
flags |= VIR_DOMAIN_AFFECT_LIVE;
}
cb_para->timer_id = virEventAddTimeout(cb_para->time_out, vnf_control_del_network_timeout_cb, cb_para, vnf_control_del_network_cb_free);
ret = virDomainDetachDeviceFlags(dom, xml, flags);
//above run in a thread function...

Better error codes when stopping a VM that is already stopped
Hi,
Sometimes when stopping a virtual domain using virDomainDestroy(), I come
across a domain that is already stopped. (For example when someone already
stopped the domain manually using virsh or because the guest OS issued a
shutdown.) This is a special case that I absolutely need to catch and handle.
Unfortunately, when this happens, and I call virGetLastError() afterwards, I
always just
