event handler
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

what a correct use for virConnectDomainEventRegisterAny API, how to Obtain a stable expected result
HI, everyone: My target deal with network hotplug use virDomainDetachDeviceFlags. Because when the API return ,the network maybe doesn’t remove from my vm guest os. So I use virConnectDomainEventRegisterAny to register an event ID: VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED , my process as follow:

why virConnectDomainEventRegisterAny can't alway trigger the callback ,how can i get a stable callback ?
hi, all: I create a vm with six nic, after the vm start, i delete tree nics. all the three nic delete logic will happen in a thread , every nic delete has the following 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,

Thread creation in Wine
Hi guys, I was looking at the thread creation API. Exactly, why do we use PTHREAD_SCOPE_SYSTEM instead of PTHREAD_SCOPE_PROCESS ? http://source.winehq.org/git/wine.git/?a=blob;f=dlls/ntdll/thread.c#l611 What is the technical difference? I remember, some years ago, that on SunOS 8 setting the latter it would make one thread only scheduled globally for the process, instead, using the first would

deadlock on connection loosing
libvirtd will lock if for example kill programm which established connection, only sigkill + restart helps., to reproduce: virConnectPtr libvirt_connection = virConnectOpen("qemu:///system"); if(libvirt_connection == NULL) { std::cout<<"failed to connect to qemu:///system\n"; exit(-1); } exit(0);

Crash after connection close when callback is in progress
Hey! It seems that if I close a connection while a domain event callback is in progress, I can easily have a crash.

when virEventAddTimeout trigger timeout ,should in the callback call virConnectDomainEventDeregisterAny ?
hi, all I do a hotplug detach a network in a thread, because virDomainDetachDeviceFlags maybe asynchronous, so I do like follow: cb_para->cluster_id = info->cluster_id; cb_para->group_id = info->group_id; cb_para->vsys_id = info->vsysid; cb_para->vnf_id = info->vnf_id; cb_para->conn = conn; cb_para->time_out = 20*1000;//20s
