I had the same issue and found out what the problem was by looking in the oVirt start-up logs - the issue was that the database was not starting, because of an operating system setting (which I documented in http://wiki.ovirt.org/wiki/Troubleshooting in the section "I am having trouble connecting to the database. In the system log, I get the following message from Postgres").

The issue is that SHMMAX is set low on Fedora 17 by default, and you need to increase it.

Let me know if this is the problem, or whether this is a different issue for you.

Thanks,
Dave.
