Thanks for the clarification Adam! The following is not directed at you but to the list in general -- actually, it probably should go to openstack-docs@ (Cc'd).

I think the way the doc (http://docs.openstack.org/trunk/openstack-ha/) is written it is easy for readers to form the impression that Pacemaker is required in order to deploy Openstack in an HA configuration. This probably wasn't the intent of the author, but for the sake of objectivity it may be a good idea to include an explanation that there are many ways HA can be implemented of which Pacemaker is the one being documented.
