[Users] Testing ovirt all in one on F18 gives error on DB creation

[Gianluca Cecchi]

Hello,
testing oVirt for with all in one config in f18 beta.
engine-setup fails in Database creation and in db log file:
saying to check log file
/var/log/ovirt-engine/engine-setup_2012_12_01_15_35_22.log
I can see
2012-12-01 15:36:32::DEBUG::setup_sequences::59::root:: running _createDB

2012-12-01 15:36:40::DEBUG::common_utils::335::root:: output = Running

error, failed creating enginedb

How can I workaround this?
Do I have to rollback what already done by engine-setup or can I only
resolve the db part?

Version I find is
ovirt-engine-setup-3.1.0-1.fc18.noarch

Thanks
