Synnefo: A Complete Cloud Stack Over Google Ganeti
summary
A complete Python/Django cloud stack sits on top of Ganeti clusters, exposing OpenStack APIs while keeping VM lifecycle inside Ganeti; production service runs since July 2011 with about 5,500 VMs in production across ~200 hosts and over 3,500 users. Storage uses a unified, content-addressable layout (4MB blocks) backed by NFS or Ceph/RADOS to enable thin, zero-copy clones and fast snapshots; networking and auth are pluggable and rolling upgrades and live migrations work in practice.
