Thanks Nirmal,
it worked, however I am seeing an exception on the console as follows -
[2014-06-08 23:08:02,151] ERROR - [HAProxy] Could not start haproxy
[2014-06-08 23:08:02,152] ERROR - [LoadBalancerExtension] Could not start

Note that I can see "haproxy" process running or started in background -
root 31424 1 0 23:08 ? 00:00:00 /usr/sbin/haproxy -f
/tmp/haproxy.cfg -p /tmp/haproxy.pid
I want to know co-relation between cartridge agent and this
haproxy-extension script.
Should the VM that runs haproxy-extension script be subscribed through
stratos and have cartridge agent running? Should cartridge agent which runs
haproxy-extension indicate itself as load-balancer cartridge - in that case
how to indicate in cartridge definition to use this extension as load
balancer overriding default loadbalancer?
Right now load balancer VM (which runs haproxy) is not started by
subscribing cartridge through stratos console but by manually using IaaS
tools.
Any pointers/guidance would be useful.
