I have a openstack juno setup 1 (controller+neutron) node and 3 compute nodes. My lbaas agent is running as seen in the service status below.

 systemctl status neutron-lbaas-agent.service

Jun 17 09:55:51 systemd[1]: Started OpenStack Neutron Load Balancing as a Service Agent.

However when I do neutron agent-list it does not show lbaas running.

The lbaas log shows the following error:

neutron.services.loadbalancer.agent.agent_manager [-] Unable to retrieve ready devices

I did the following configurations for lbaas:

I added the following line in the default section of neutron.conf on my controller+neutron node:

service_provider=LOADBALANCER:Haproxy:neutron.services.loadbalancer.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

and added lbaas at the end of the service_plugin line:

service_plugins =neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,lbaas

Also I uncommented the following lines in lbaas_agent.ini

interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
device_driver = neutron.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver

I had done a packstack setup and lbaas was not enabled from start as i had edited the answer file to not install it. So, I made the above changes and enabled the service and started it. Do I have to install haproxy separately? Please help me resolve the issue.
