I am using latest devstack as of today on F20 There are a couple of known bugs that can prevent rabbitmq-server from starting on F20. First one (same bug, two BZs) is related to SELinux and port probing: https://bugzilla.redhat.com/show_bug.cgi?id=1032595#c8 https://bugzilla.redhat.com/show_bug.cgi?id=998682 Second one is a race condition in Erlang. If you are repeatedly unable to start rabbitmq-server, it's probably not this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1059913 I have a patched rabbitmq-server package which includes the fixes for these two issues, if you'd like to try it and see if it helps your issue. And if it helps, please comment on the bug(s) to encourage the maintainer to pull them into the package :) http://jeckersb.fedorapeople.org/rabbitmq-server-3.1.5-3.fc20.noarch.rpm Hope that helps, John
