Comment 2 for bug 1339596

Here is the original problem:

2014-07-08T15:47:13.935362+00:00 err: Could not start Service[rabbitmq-server]: Execution of '/etc/init.d/rabbitmq-server start' returned 2:

Due to this "cinder-scheduler" package was not even installed:

2014-07-08T15:47:21.316247+00:00 notice: (/Stage[main]/Cinder::Scheduler/Package[cinder-scheduler]) Dependency Service[rabbitmq-server] has failures: true
2014-07-08T15:47:21.317719+00:00 warning: (/Stage[main]/Cinder::Scheduler/Package[cinder-scheduler]) Skipping because of failed dependencies

Checking into logs further to see why rabbitmq start failed.
