-Even for larger environments, you might have nodes spun up from other tools.  You don't have to use Ansible to spin up guests.  Once these are created and you wish to configure them, the Rackspace Cloud API can be used to return system grouping with the help of the rax inventory script. This script can be used to group resources by their eta data.  Utilizing meta data is highly recommended in rax and can provide an easy way to sort between host groups and roles.

-When using ``rax.py``, you will not have a 'localhost' defined in the inventory.  As mentioned previously, you will often be running most of these modules outside of the host loop, and will need 'localhost' defined.  The recommended way to do this, would be to create an ``inventory`` directory, and place both the ``rax.py`` script and a file containing ``localhost`` in it.  Executing ``ansible`` or ``ansible-playbook`` and specifying the ``inventory`` directory instead of an individual file, will cause ansible to evaluate each file in that directory for inventory.
