1. What is the problem? Nova API-GW and Cinder API-GW code are still in the repository of the Tricircle project. 2. What is the solution to the problem? According to the blueprint for the Tricircle splitting: https://blueprints.launchpad.net/tricircle/+spec/make-tricircle-dedicated-for-networking-automation-across-neutron Nova API-GW and Cinder API-GW related code should be removed from the repository of the Tricircle project. 3. What the features need to be implemented to the Tricircle to realize the solution? No new features. Change-Id: I152bab9c0a7a114f0361a69a3ab2d7037731434fchanges/82/384182/3
