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 <a href="http://wiki.ovirt.org/wiki/Troubleshooting" target="_blank">http://wiki.ovirt.org/wiki/<u></u>Troubleshooting</a> in the section "I am having trouble connecting to the database. In the system log, I get the following message from Postgres").<br>
<br>
The issue is that SHMMAX is set low on Fedora 17 by default, and you need to increase it.<br>
<br>
Let me know if this is the problem, or whether this is a different issue for you.<br>
<br>
Thanks,<br>
