Hi In my program , When libvirtd restart , the old libvirtd connection(virConnectPtr) has to reconnect, Before usr old virConnectPtr , I call virConnectIsAlive. but when I restart libvirtd , virConnectIsAlive return 1, and I continue other operate use the old virConnectPtr, program will receive signal pipe. I use libvirt event. before any api use, I call virEventRegisterDefault...

Dell Customer Communication Hi All, I am using Compiled against library: libvirt 1.2.9 Using library: libvirt 1.2.9 Using API: QEMU 1.2.9 Running hypervisor: QEMU 2.1.2 I want user to provide username and password authentication to virConnectPtr virConnectOpenAuth(const char *name, virConnectAuthPtr auth, unsigned int flags) to login remotely for the qemu hypervisor. But it is not taking user provided username and driver. Because internally it is calling below qemu driver function, static virDrvOpen...
