If I had these constraints I would add a loadbalancer-config on the same machine that runs the OpenStack apis. So add keepalived with haproxy on the 2 “OpenStack controllers”. Keepalived for a VRRP based HA-IP and haproxy for load-balancing (with the nice addition you can do SSL offloading on haproxy). This is somewhat similar to what what most vendors (Mirantis/Ubuntu/RedHat) are doing AFAIK. If you use neutron with the L3 agent you will also have to think about HA of that. That’s a different story though and I am not really up to speed on the latest and greatest there.
