Fixed In Version: libvirt-0.10.2-29.el6_5.2
Doc Type: Bug Fix
Doc Text:
Cause: When de-registering last callback for an event, improper variable was used for the de-registration of the event itself. Consequence: Error "libvirt: XML-RPC error : internal error: domain event 0 not registered" was returned even though the code was used properly. Fix: We changed the code to use the proper variable. Result: Now de-registering last callback for any event will not return an error and the event will be de-registered as it should've been.

                                                    VIR_DOMAIN_EVENT_ID_REBOOT,
                                                    VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback2),
                                                    strdup("cb1"), myFreeFunc);
