This seems ok since it uses nslookup for searching the ip address and it
doesn't find the hostname on DNS.

I'm using ovirt-3.2 on Fedora 18 and I can't reproduce the JBoss issue
using only /etc/hosts without DNS.
I don't think it's related to name resolution.
AIO uses urllib2 for checking the Healt Page and it should work also if
you're using /etc/hosts only.
It seems that ovirt-engine service is not started.

Please run engine-cleanup, engine-setup and check ovirt-engine status if
it fails again.
If it fails, can you please attach your logs?
