[Users] Addition of nodes to oVirt-engine

Good evening to all, I have added two nodes of Fedora 17 with vdsm 4.10 installed to oVirt 3.1 engine. I was having problems with SSL, so I have disabled it. When I added the nodes there was no attempt of installation as it was the case with oVirt 3.0, but the nodes get activated, provided that ovirtmgmt bridge is present. I have been told that there is a configuration in the database that make this happen. I just recreated the database via the script /dbscripts/create_db_devel.sh and run engine-setup, after removing all packages from oVirt 3.0 and jboss and installing ovirt 3.1 basic packages. My question is: What would be the 'standard' procedure to get oVirt 3.1 running? Regards, Jose Garcia
