| 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.
