Hi,

Additional information:

After removing and re-running engine-setup, I try once again to run 
ovirt-engine. I get the following error in the logs:
==> /var/log/ovirt-engine/console.log <==
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Nothing else, unfortunately, and I have no idea how to debug JBoss AS to 
figure out what's going wrong.

Are there any requirements in terms of the JRE which aren't specified in 
the quick start guide?

Thanks,
Dave.
