[Users] Update of oVirt 3.1

[jose garcia]

Good evening,

     I had installed the 3.1 beta version. After an update of Fedora 17, 
the portal does not show any links. I reckon that ovirt-engine version 
has been upgraded to 3.1.0-1.fc17.

     Have I lost all the information in the database? Is there a way to 
bring back the datacenters and the nodes info?

Regards,
Jose Garcia
