[Openstack-operators] Adding a Physical Network Interface to an Instance

Ok, I did not boot from the console, I booted from Horizon.  So i did not use any options.  
 
I also assigned the 1.1.1.1/24 to that network in horizon.  It was already part of the project.  

When I did a nova-manage network list on the controller box, it was only showing the 1.1.1.1 network.

I deleted the 1.1.1.1 network to start over through horizon.

So now in Horizon, I see my original network, but when I do a nova-manage network list I still only see the 1.1.1.1  I tried to delete it but it says it cannot be found.

i think i messed something up by using Horizon.  I rebooted the Controller and the Compute box and it still just shows the 1.1.1.1 network.
