That's OK OpenJDK 1.8 is the default version for CS8, it cannot be removed

That's OK, OpenJDK 11 is required for oVirt. The easiest way to force using
OpenJDK 11 is to set JAVA_HOME in $HOME/.bash_profile:

JAVA_HOME=/usr/lib/jvm/java-11
PATH=$JAVA_HOME/bin:$PATH

export JAVA_HOME PATH

That way you will ensure that you are using OpenJDK 11

Regards,
Martin
