This was a little roadblock that I ran into when deploying
using openstack-ansible recently. The documentation doesn't
indicate that configuration of a load balancer is explicitly
required, and since the HAProxy installation playbook didn't
run automatically on setup-everything.yml the errors that I
got didn't lead me to figuring out that HAProxy was the
missing piece.
