There is a nova-scheduler service running on the controller:

Binary           Host                                 Zone             Status     State Updated_At
nova-cert        os-controller.int.seas.harvard.edu   nova             enabled    :-)   2012-06-15 20:41:44
nova-scheduler   os-controller.int.seas.harvard.edu   nova             enabled    :-)   2012-06-15 20:41:45
nova-volume      os-controller.int.seas.harvard.edu   nova             enabled    :-)   2012-06-15 20:41:47
nova-compute     os-host.int.seas.harvard.edu         nova             enabled    :-)   2012-06-15 20:41:46

That was just me accidentally omitting it from the list.

I don't really know anything about AMQ or how OpenStack utilizes the
message broker.  Are there any commands I can run that would exercise
the message broker and confirm whether or not it is working correctly?

Well, scheduling and/or deleting, due to my failed attempt to delete
some of these instances:

mysql> select id,hostname,vm_state,task_state from instances;
+----+----------+----------+------------+
| id | hostname | vm_state | task_state |
+----+----------+----------+------------+
|  1 | lars0    | building | deleting   | 
|  2 | lars1    | building | scheduling | 
|  3 | lars0    | building | deleting   | 
|  4 | lars2    | building | scheduling |
