OpenStack Quantum

Quantum is a virtual networking service for OpenStack.


Current status

  • Targeted release: Fedora 17
  • Last updated: January 12, 2012
  • Percentage of completion: 0%

Detailed Description

Quantum is a virtual networking service developed for the OpenStack cloud computing platform, but also applicable to other advanced virtual machine network deployments. The Diablo release of Quantum has been available for Fedora 16 for several months as a standalone service. Fedora 17 will include the Essex release of Quantum, integrated with the the Essex release of OpenStack Compute (nova). Plugins will be provided supporting Feature/Open vSwitch, Linux bridging, and certain Cisco products for network transport between VMs within and across hosts.

Information on the upstream project is available at Quantum Launchpad and Quantum Wiki.

Benefit to Fedora

Fedora users will be able to construct and manage arbitrary independent virtual layer 2 networks for OpenStack clouds or other large-scale virtual machine deployments. These virtual networks are realized using any of several included plugins, or a custom plugin.

As Quantum continues to evolve, layer 3 and higher constructs such as routing, VPNs, firewalls, and load balancing will be incorporated.


This feature involves packaging, integration, and testing for Fedora, along with participation in the upstream development community. The current Diablo-based rawhide package will be upgraded to the Essex E3 milestone release prior to the F17 Branch Freeze, to the Essex E4 milestone release prior to the F17 Beta Change Deadline and to the final 2012.1 Essex release prior to the F17 Final Change Deadline.

How To Test

Quantum will be tested along with other OpenStack components as part of OpenStack Test Day. Test procedures will be developed and documented in preparation.

User Experience

OpenStack users will have the option of installing and deploying Quantum and using it manage tennant networks. Other users can explore Quantum's capabilities, and integrate it with their infrastructure.


All external dependencies (mainly python libraries) for Quantum's core and its Linux bridge and Cisco plugins are already in Fedora. The ability to use Quantum's Open vSwitch plugin depends on inclusion of Feature/Open vSwitch in Fedora 17.
