Thanks for links Sébastien.

Is using pacemaker/corosync (as opposed to haproxy + keepalived) for the
opensource services the preferred method for making openstack HA?  Also is
it possible with pacemaker to run the services in an Active/Active
configuration with load balancing?  Pardon my ignorance if these are stupid
questions... this is my first encounter with HA.

Thanks again for the help!

Sam
