Question about simplestreams and imagemetadata

[Jeroen Vermeulen]

Hi folks,

I'm trying to figure out why simplestreams isn't working for the Azure 
provider.

The problem lies in matching the product IDs.  From the image constraint 
we pass, the imagemetadata code decides that we're looking for product 
IDs like

     com.ubuntu.cloud:server:12.04:amd64

The structure of that ID is encoded in ImageConstraint.Ids(), in 
environs/imagemetadata.

But the product IDs in the simplestream data look like:

     com.ubuntu.cloud:server:12.04:amd64:azure

(See 
http://cloud-images.ubuntu.com/releases/streams/v1/com.ubuntu.cloud:released:azure.json 
for these).

Does anyone know how this is supposed to work?  Am I doing something 
wrong, or does something outside our provider need to change?
