I've created a new blueprint for centralizing and cleaning up configuration options for Ocata: https://blueprints.launchpad.net/nova/+spec/centralize-config-options-ocata Please start moving existing changes, or create any new changes, in that blueprint rather than the newton blueprint: https://blueprints.launchpad.net/nova/+spec/centralize-config-options-newton -- Thanks, Matt Riedemann
