Golden Image Flow

We want a user to have a similar experience for openstack users regardless of the hypervisor.

Story:

• user uploads raw[.gz?] image to glance (optionally support internal format although we want to encourage raw as the standard) in cloud.
• Nova-compute can convert to an optimized runtime format (if needed) at runtime.
• The user snapshots, which uploads the snapshot to glance - in either raw or internal format.
• The user can launch multiple copies of the snapshot.
• The user can download the snapshot (which is converted to raw on client)

Implications

• Does nova support gziped raw images?
• glance client would need work with qemu-img to convert back to raw?

• Post ingestion glance converts to an optimized runtime format.
• The user snapshots, which uploads the snapshot to glance - in either raw or internal format.
• The user can launch multiple copies of the snapshot.
• The user can download the snapshot (which was converted to raw on service)
