Please have a close look at the ``main.yml`` for tunable parameters.
The most important change is to set Octavia into ACTIVE_STANDBY mode
by adding ``octavia_loadbalancer_topology: ACTIVE_STANDBY`` to the
user file in /etc/openstack-deploy
by adding ``octavia_loadbalancer_topology: ACTIVE_STANDBY`` and
``octavia_enable_anti_affinity=True`` to ensure that the active and passive
amphora are (depending on the anti-affinity filter deployed in nova) on two
different hosts to the user file in /etc/openstack-deploy
To speed up the creation of load balancers or in a SINGLE topolgy
to speed up the failover a spare pool can be used.
