Hello, I am new to OpenStack and trying to install the diablo release on a RHEL6 cluster. I follow instructions here: http://fedoraproject.org/wiki/Getting_started_with_OpenStack_Nova The instruction doesn't mention how to install and configure Keystone and dashboard services, I wonder: 1) are these two services available for RHEL6, in diablo release? 2) do I need to go to the latest Essex release, and where the instructions is? Thanks, Xin
