The Xen Project community develops leading open source virtualization technology that powers more than 10 million users across enterprise, cloud computing, desktop infrastructure and embedded and mobile devices. The project powers some of the largest clouds in production today, such as AWS, Rackspace Public Cloud, Verizon Cloud, AliCloud and many hosting services.

The annual Xen Project Development Summit brings together the developers and users who define the Xen Project ecosystem and plan for the future of the Project, its surrounding infrastructure and management tools.

This year the event is co-located with the Linux Foundation's LinuxCon North America, CloudOpen North America, the Linux Plumbers Conference, KVM Forum and ContainerCon. 

We invite you help shape Xen’s future by submitting a speaking proposal for the Xen Project Developer Summit taking place Aug. 17-18 in Seattle.

Submitting Your Proposal

Abstracts due: May 12, 2015

Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length from 25 to 45 minutes (please specify if you need a specific length).  Also include proposal type; one of the following:

  • Technical talk
  • End-user talk
  • Hands-on / BoF
  • Panel Discussion

You will receive a notification of whether or not your presentation proposal was accepted by May 15, 2015.


A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, it should focus on the work that needs to be done or the difficulties that have not yet been solved, any lessons that have been learned, etc.  Summarizing recent developments is okay, but they should only be a small portion of the overall talk.


For developers, one of the biggest challenges is understanding what, where and how people actually use our software.  We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using Xen Project in production, we encourage you to submit a speaking proposal. As an end user, this is a unique opportunity to share your input directly with developers.


We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. This time can also be used for hands-on hacking sessions if you have concrete code problems to solve. 


If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your abstract. We will request full biographies if a panel is accepted.

Submitting Your Slides

You can now submit your slides directly through the CFP management system immediately when you submit your initial proposal or any time before the event by logging into your account, choosing your presentation and uploading your slides. We only accept presentation slides in PDF format to ensure that there are no formatting issues.
