I'm well aware of the existing race condition within the Liberty Cinder code, that's why I configured my HAProxy to be sticky to just one Cinder, and move on to the others when the active one goes down.<br>
Now, since my HAProxy nodes are the same as my Controller Nodes, and Cinder binds to all Interfaces, haproxy can't bind to the VIP address.<br>
If it is impossible to bind Cinder to just one interface, is there a way to change to Port it binds to?<br>

The binding Address is definded in the registered Endpoind.<br>
Try "nova endpoint list" to find out where your services are binding.<br>
And nova endpoint edit <ID> to edit your endpoint.<br>
