You should modify this file and add a category for EncryptionUtils - look at how the category - <logger category="org.ovirt"> <level name="INFO"/> <handlers> <handler name="ENGINE_LOG"/> </handlers> </logger> Is defined.

What you should do is add <logger category="org.ovirt.engine.core.engineencryptutils"> <level name="FATAL"/> <handlers> <handler name="ENGINE_LOG"/> </handlers> </logger> Near the logger category for "org.ovirt" (I mean, as a sibling to that element). Pay attention that here i defined it for FATAL - you may wish to try it with DEBUG to see the stacktrace.
