It fits in the Virtualization and Monitorization Driver section according to OpenNebula's Architecture. https://github.com/OpenNebula/addon-lxdone
- 21. © OpenNebula Systems SL Third Party Integrations Corona: Distribute OpenNebula in Docker containers CORONA is a containerized OpenNebula deployment. The primary goal is to build a OpenNebula deployment which can easily be rolled out or rolled back. At the moment the plan is to split the services into 3 containers libvirt, onenode, and oneserver. https://github.com/fasrc/corona
