Feature Name OpenNebula

OpenNebula is an Open Source Toolkit for Data Center Virtualization.


OpenNebula is an open-source cloud computing toolkit for managing heterogeneous distributed data center infrastructures. The OpenNebula toolkit manages a data center's virtual infrastructure to build private, public and hybrid IaaS (Infrastructure as a Service) clouds.

Detailed Description

OpenNebula is an Open Source framework for Data Center Virtualization. The project is designed to be scalable and offer compatibility with Amazon EC2 the Open Cloud Computing Interface (OCCI).

It includes a core (oned) which orchestrates the deployment and management of Virtual Machines, and is managed via a CLI, a web service (Sunstone), and language specific bindings (Ruby, Java and Python).

It also features management of Virtual Data Centers.

Benefit to Fedora

Allow Fedora to have an integrable and extensible framework for Data Center Virtualization.


Get all dependencies into Fedora, and build a single package that provides OpenNebula. Upstream will test it.

How To Test

OpenNebula must be tested in a physical server, not a Virtual Machine, since it requires virtualization extensions to manage Virtual Machines. The physical server must have virtualization capabilites.

A typical OpenNebula installation requires external servers to handle virtualization, but for these purposes the same server can be used as:

  • OpenNebula frontend: opennebula package + dependencies
  • OpenNebula node: a hypervisor of choice. Libvirt + KVM recommended.

After installing the software, these tests should be run to validate the package:

  • Manage a Virtual Machine with the CLI (following these instructions). This implies creating a network, registering a host, an image, etc.
  • Use the graphical user interface (sunstone) to do the same thing.

User Experience

Fedora users will be provided with a CLI and a web-based GUI to manage VMs.
