13.7. Integrating Xen with Pacemaker

In order to fully capitalize on the benefits provided by having a DRBD-backed Xen VBD’s, it is recommended to have Heartbeat manage the associated domU’s as Heartbeat resources.

You may configure a Xen domU as a Pacemaker resource, and automate resource failover. To do so, use the Xen OCF resource agent. If you are using the drbd Xen device type described in this chapter, you will not need to configure any separate drbd resource for use by the Xen cluster resource. Instead, the block-drbd helper script will do all the necessary resource transitions for you.
