[Users] DEBUG loglevel for engine-manage-domains?

Hi everyone, how is the right way to get engine-manage-domains more verbose? I found a log4j.xml in utils.jar but my configuration seems not to work still only INFO and ERROR in /var/log/engine/engine-manage-domains/engine-manage-domains.log. I'am running Fedora 17 with ovirt 3.1 [1].
