In that documentation it looks like each openstack service gets it own IP (keystone is being assigned 192.168.42.103 and glance is getting 192.168.42.104).
I might be missing something too because in the section titled "Configure the VIP" it create a primitive called "p_api-ip" (or p_ip_api if you read the text above it) and then in "Adding Keystone resource to Pacemaker" it creates a group with "p_ip_keystone"??? Stranger yet, "Configuring OpenStack Services to use High Available Glance API" says: "For Nova, for example, if your Glance API service IP address is 192.168.42.104 as in the configuration explained here, you would use the following line in your nova.conf file : glance_api_servers = 192.168.42.103" But, in the step before it set: "registry_host = 192.168.42.104"? So I am not sure which ip you would connect to here...
