BTW, you don't pre-create hosts when using cloud machines. You should be using the rackspace dynamic inventory script.
You would still use add_host, but if you are trying to predefine the system in your INI based inventory, that's not really the way it's meant to work. The cloud is meant to be authorative. Can you still use group variables? Sure. Should you it to define hostnames prior to creating instances -- no.
