The osapi_extensions_path nova flag currently defaults to /var/lib/nova/extensions. This directory is most useful for custom 'user' extensions (stuff that doesn't like in the nova core source tree).

It would be nice to have an extensions directory within the nova tree which we could use for 'core' extensions. This would provide a good place to add extended OS API features that are not part of the official spec but exist within the nova source code base. The core extension mechanism should probably provide a way to make core extensions optional such that they can also be disabled.
