If the connection is unexpectedly disconnected, I get an error when calling virConnectUnregisterclosecallback(): [Code-55] [Domain-20] Requested operation is not valid: A different callback was requested If I don't unregister the callback, virConnectClose() indicates a leak. The same happens for domain events. If the connection is closed unexpectedly, I get: [Code-1] [Domain-7] internal error: client socket is closed I am not even sure that I don't get a leak whatever I do about since I don't see anything that would unset the callbacks when the connection is closed (while this happens for close callback). I see that virsh has the same problem. If I restart libvirt while connected, I get a "One or more references were leaked after disconnect from the hypervisor". -- Tempt not a desperate man. -- William Shakespeare, "Romeo and Juliet" _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
