and enable: True in /etc/openstack-dashboard/local_settings ( Restart
httpd) but still i am not able to see "Load Balancer" button in
Network section, I am using mitaka Does it has different configuration
to enable lbassv2 on horizon interface?

    'enable_firewall': False,
    'enable_ha_router': False,
