been doing some tests on baremetal hosts, but I'm kind of stuck here, it's getting to start to be frustrating.

I've followed the documentation from http://docs.openstack.org/developer/tripleo-docs/

First I've tried the stable version from liberty and got stuck in a python-config-oslo outdated package bug.

Then I've tried mitaka and I got stuck in this error: 

"Could not retrieve fact='rabbitmq_nodename', resolution='<anonymous>': undefined method `[]' for nil:NilClass Could not retrieve fact='rabbitmq_nodename', resolution='<anonymous>': undefined method `[]' for nil:NilClass"

My question is if there's a stable version that can be installed on overcloud baremetal hosts that we can rely on? 

Thanks
