BTW I really wouldn't recommend using the OS:: namespace for your own 
custom types.

You want the second one.

You're assuming here that doing get_attr on your provider resource will 
automatically reach into the nested stack and pull out the attributes of 
the resource you're thinking of - which of course would require Heat to 
be clairvoyant ;)

You actually need to explicitly export the attributes you want as 
outputs from the instance.yaml template, just as you defined parameters 
to accept the property values. To make this a bit easier, you can get 
the API to generate a template that you can modify with the command:

   heat resource-type-template -t hot -F yaml OS::Nova::Server
