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.
