Comment 1 for bug 1318912

   With the help of Marica(<email address hidden>) from OpenStack mail list,I changed RA which named neutron-agent-l3,and now it works.I have attached my modified RA.hope it help anyone else.
   In my way,both node should set diffrent hostname in /etc/sysconfig/network,and when l3-agent started by pacemaker,the node's hostname will be changed to network-controller automatically,so whichever node start the l3-agent,it's hostname would be the same.This idea is from Marica.
   I have changed few lines based on Marica's RA and https://bugs.launchpad.net/openstack-manuals/+bug/1252131
