Configuring Keystone and Glance with Pacemaker and Corosync

This recipe represents two nodes running both Glance and Keystone, controlled by Pacemaker with Corosync in active/passive mode, which allows for a failure of a single node.

Getting ready

We must first create two servers configured appropriately for use with OpenStack. As these two servers will just be running Keystone and Glance, only a single network interface and address on the network that our OpenStack services communicate on will be required. This interface can be bonded for added resilience.
