I've installed OpenStack Icehouse on Ubuntu 14.04 LTS and configured neutron as per chapter 7 in the installation guide. I loose connectivity to the host shortly after adding a port to the external bridge. I've been struggling with it for a while now. Any assistance would be greatly appreciated.

I don't know why this configuration is not automated when configuring the bridge. It would make a lot of sense to do so.

  br-ex should have IP which was assigned to eth0, eth0 should not have IP at all

On F20 it looks like this http://bderzhavets.blogspot.com/2014/...

I did come across this. I would have assumed though that it would be automated. So do I need to manually configure it? My host is Ubuntu, so I edit the interfaces file?

Yes, edit interfaces files
