I have enabled LBaas on my openstack, but after adding a pool, vip, members,
and monitor successfully I am still unable to get load balancing working.
I found this blog to help me so far
http://kimizhang.wordpress.com/2013/08/08/openstack-grizzly-quantum-advanced-features-2/
When I run # ps -ef | grep haproxy I dont get much:
root 27508 2718 0 14:16 pts/1 00:00:00 grep haproxy
My logs show an issue with haproxy:
RuntimeError:

'netns', 'exec', 'qlbaas-e10951cd-4cca-4ba4-acc0-0ccde6817029', 'haproxy',

Any ideas?

Subject: Re: [Openstack] Install/Enable Quantum lbass (load balancer) feature?
Hi Jake,
Regarding lbaas in grizzly working on RHEL/Centos - it may be problematic as
host operation system must support network namespaces.
If you do have support for network namespaces then you need to do the following
steps to setup lbaas service in quantum:
1) specify lbaas plugin in quantum.conf:
service_plugins= lbaas_plugin_classpath.
check quantum/plugins/services/agent_loadbalancer/plugin.py for correct path as
currently the name and path has changed.
2) to enable lbaas service in horizon you need to do the following:
add the following piece of code to
horizon/openstack_dashboard/local/local_settings.py :
OPENSTACK_QUANTUM_NETWORK = {
'enable_lb': False
}
3) start quantum-lbaas-agent on the host providing quantum.conf and
lbaas-agent.ini. lbaas-agent.ini should reflect core plugin configuration
(should have proper interface driver)
Note that if host os has no namespace support, all of above will work (e.g.
REST API will be functional), but you would not be able to deploy loadbalancer
as lbaas agent can only work with namespaces.
Thanks,
Eugene.
