There are two blueprints for doing disk encryption with Nova: 1) Encryption of Attached Cinder Volumes (has a working prototype) and 2) Encryption of Local Ephemeral Disks. This session presents the architecture of our prototype implementation to solicit feedback from the community and to discuss open questions regarding the current implementation prior to its submission for Havana. Consensus from the community is also desired regarding how to extend the existing prototype to support encrypted ephemeral storage.
