Deploy your own “cloud” with Debian “Wheezy”

The Debian Project produces an entirely Free operating system that

empowers its users to be in control of the software running their

computers. These days, more and more computing is being moved away from

user computers to the so-called “cloud” – a vague term often used to

refer to Software as a Service (SaaS) [1] offerings. We are concerned

that, without the needed care, this trend might put in jeopardy most of

the freedoms that users enjoy when running (on their computers)

software that is Free according to the Debian Free Software

Guidelines [2].



We encourage Debian users to prefer cloud offerings where the SaaS

infrastructure is entirely made of Free Software and can be run under

their control. We encourage Debian users to deploy their own clouds, as

the ultimate way to retain all the freedoms that Debian stands for.

To help our users with these tasks, we are proud to announce the

availability of several new technologies that would ease the deployment

of Debian-based clouds. Starting with the forthcoming release of Debian

7.0 “Wheezy”, users will find ready-to-use packages for OpenStack® and

Xen Cloud Platform (XCP). OpenStack®, the open source cloud OS, has

been created to drive industry standards and end cloud lock-in.

OpenStack® is a common, open platform for both public and private

clouds with the support of more than 2,600 global project participant

and over 150 industry leading companies. The open source cloud

operating system enables businesses to manage computers, storage, and

networking resources via a self-service portal and APIs on standard

hardware at massive scale. To find out more about OpenStack®, you can

visit the official website [3].


The Xen Cloud Platform (XCP) is a Free Software project that is hosted

by [4] that delivers an enterprise-ready server virtualization

and cloud computing platform. XCP integrates with the following cloud

orchestration stacks: CloudStack, OpenNebula and OpenStack®. To find

out more about XCP, you can visit the website of the project.


The work to finalize Debian 7.0 “Wheezy” is still ongoing, but

packages of the above technologies are already available as part of our

“testing” release [5]. We encourage interested users to test them. In


* You can set up a minimal but fully functional OpenStack® cluster

using two computers by following the HOWTO on the Debian wiki [6]

* You can test XCP installation and deployment by installing

the xcp-xapi [7] package and following the instructions in its

README.Debian file

* You can test OpenStack® using XCP by installing nova-xcp-plugins

[8] in your XCP server, and following the instructions in its

README.xcp_and_OpenStack file





“Preserving user freedoms in the cloud is a tricky business and one of

the major challenges ahead for Free Software. By easing the deployment

of Debian-based private clouds we want to help our users in resisting

the lure of giving up their freedoms in exchange of some flexibility,”

said Stefano Zacchiroli, Debian Project Leader.

For Lars Kurth, Community Manager at, “Debian and Xen have a

long uninterrupted history: thus, I am really pleased that Debian is

the first Linux distribution to contain XCP packages. Until now, it

was only possible to use XCP in Linux appliances within a tightly

controlled environment. In Debian “Wheezy” we changed how users

interact with XCP, providing much more flexibility and enabling anybody

to use Debian as a XCP Dom0 kernel. This enables Debian users to build

cloud services based on the leading Free Software virtualization

platform that is powering some of the largest clouds in production


“Having OpenStack packages included in Debian confirms the great job

done by the OpenStack community to deliver high-quality free/libre

software. It’s exciting to collaborate with the Debian developers to

enable building clouds based entirely on Free Software,” added Stefano

Maffulli, OpenStack® Technical Community Manager.

Please let us know if you encounter any problem, using the Debian

bug tracking system [9].


About Debian


The Debian Project was founded in 1993 by Ian Murdock to be a truly

free community project. Since then the project has grown to be one of

the largest and most influential open source projects. Thousands of

volunteers from all over the world work together to create and maintain

Debian software. Available in 70 languages, and supporting a huge range

of computer types, Debian calls itself the “universal operating system”.
