Comment 2 for bug 1495713

Workaround for release-notes:

When a cluster is provisioned in openstack HA mode, if the user does not explicitly specify the values for the following parameters, then the system assumes 100 for these values. Having same values for both of these parameters is not recommended as it might exhibit issues when a node goes down and another nodes takes over the vIP.

 'internal_virtual_router_id' : 180, #Default = 100
 'external_virtual_router_id' : 190, #Default = 100

It is highly recommended that the user specify the values for the above parameters in testbed.py while provisioning.

On an already provisioned system, the user can edit the values in /etc/keepalived/keepalived.conf file. Look for virtual_router_id in the file. Note: After editing the file, restart keepalived process by "service keepalived stop" and "service keepalived start".
