Open Stack

My problem actually is that I have three controller nodes that are also my HAProxy nodes as well, and I want just one of my Cinders to be actively receiving connections through HAProxy, while the other two cinders are on hot standby, should the active one fail. 
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.
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.
If it is impossible to bind Cinder to just one interface, is there a way to change to Port it binds to?

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