Getting Started Hacking OpenNebula - Fosdem-2013
The document discusses OpenNebula, an open-source cloud computing platform. It provides an overview of OpenNebula's architecture and components, and how developers can create custom drivers to integrate new virtualization technologies, storage solutions, and cloud interfaces. The presentation also explains how OpenNebula uses drivers to manage tasks like virtual machine deployment and image transfer between components.
