however, I can reach only the first floating pool ip, but not the second pool initially. I played around and I was able actually to reach both ip pools, but afterwards, I was not able to launch more instances at all, the instance stuck in the “Build” state,
it apparently stuck in the “network” part, but I can not find any useful message from the log files.<o:p></o:p></span></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been testing multiple floating ip pools with neutron network on CentOS 6.5 with icehouse. The single floating ip pool set up worked fine, but I encountered many problems setting up multiple floating IP pools. I now enabled l3-agent
with empty string (in /etc/neutron/l3-agent.ini) for multiple <o:p></o:p></p>
<p class="MsoNormal">gateway_external_network_id = <o:p></o:p></p>
<p class="MsoNormal">external_network_bridge =<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The external bridges, br-ex and br-ex2, do not have the qg-* port at all, these qg-* interfaces are now in the br-int, therefore the floating ips do not work anymore. Is there any way to move “qg” port from br-int to br-ex, and br-ex2?
I don’t know how I ended up with such a mess, do I have to remove the network set up and reconfigure neutron?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much for your help.<o:p></o:p></p>
