We've moved away from devtest in favor of the installation method documented at http://docs.openstack.org/developer/tripleo-docs/

We might accept a patch to fix this, but devtest is no longer CI'd so it's likely to break again at some point.

Sorry for the hassle, but devtest just proved too difficult to use as a production tool.
