If this is all done under the same API calls that are determined to represent core, then the implementation isn’t necessarily a concern. If you require special extensions or unique API calls to access containers or bare-metal options, then those would have to go through the same evaluation process.</div><div><br></div><div>Eventually, this points to where DefCore and Tempest testing evolve so that we include some of the emerging ‘scenario testing’ vs. just the current API validation. Moving down this path would be a necessity to get the interoperability we seek in the long term IMHO.

Docker with OpenStack is kinda like a PaaS and kinda like a IaaS. We would like to be able to deliver it in the cloud as an option alongside our various hypervisors as well as bare metal. Delivered on a Nova compute host means the host should be restricted to a single tenant which is unusual.
