Tested openstack-quantum-2012.2.3-8.el6ost.noarch

I have configured quantum.conf with two hosts.


First IP doesn't use qpid , Second one is the real qpid 

So connecting to first qpid failed and later the second one was used.

#qpid_hostname = 10.35.160.77

qpid_hosts = 10.35.160.89:5672,10.35.160.77:5672
restarted quantum services and checked server.log

also tested when qpid ip is not alive on the network
