OVM Templates adn root password

I have trying to install JDE using the OVM templates following the OVM express installation guide (E54942-03).

I have a server with OVS 3.3.1, OVManager and NFS/HTTP server running.

I can go as far as launching the VM (the web server in this example) and its console. I can login as oracle/ovsadminE1 but not as root.
It does not recognize the password I entered while doing the ./config.sh process as per documentation in the OVM express installation guide (E54942-03)

Anybody implemented the templates ?
