My experience in upgrading from oVirt-3.1/Fedora 17 to oVirt-3.2/Fedora 18:

On Fedora 17:
Be sure to have the latest updates running: yum distro-sync
Set exclude=ovirt* in /etc/yum.conf
Execute: fedup --disablerepo=ovirt* --network 18

When you have a running Fedora 18:

# systemctl list-units --failed

# tar cJvf pgsql-backup.tar.xz /var/lib/pgsql/data/
# yum install postgresql-upgrade

# cp /var/lib/pgsql/data/pg_hba.conf /root/pg_hba.conf.ovirt

edit /var/lib/pgsql/data/pg_hba.conf changing md5 to trust on the local line.

Remove the line exclude=ovirt* from /etc/yum.conf

# yum update ovirt-engine-setup
# engine-upgrade

However, during the upgrade I've stepped into
https://bugzilla.redhat.com/show_bug.cgi?id=906270
We are still working on the upgrade actions.
