In April this year, Xen became a Linux Foundation Collaborative Project. 6 months later it is time to take stock. I will start with a brief introduction of the Xen Project, explain why Xen moved to the Linux Foundation, explore the impact on the community and provide an outlook for the future. I will use examples from the Xen Project community to explore the challenges and benefits of becoming a collaborative project, draw lessons and explore tools to help make your project more successful. I will cover a wide range of topics ranging from community management, collaboration infrastructure, marketing, and good governance to align the interests of a project’s stake-holders. By employing each of these techniques in a complementary fashion, we can ensure the long-term success of a project.

An Open Source Hypervisor > 10M Users Powering some of the biggest Clouds in Production Amazon Web Services, Rackspace Public Cloud, Terremark, … Several sub-projects Xen Hypervisor (including Xen on ARM), XAPI management tools, Mirage OS Linux Foundation Collaborative Project Sponsored by Amazon Web Services, AMD, Bromium, Calxeda, CA Technologies, Cisco, Citrix, Google, Intel, NetApp, Oracle, Samsung and Verizon 10 years old
  • 10. Four Key Issues Symptoms Consequences for Xen Fixes that were applied Effect this had (there may be others) At the end : Reflection & Tools Magnifying effect
  • 11. Unwritten Rules Undefined Roles Lack of Upfront Collaboration
  • 12. Hard to join the project Vendors got frustrated Hard to work with the project
  • 13. Another key vendor nearly dropped Xen Growth potential was limited early Roadmap & Release Management 1st KVM release Canonical drops Xen RedHat drops Xen in RHEL6 Technical Coordination Team Xen Governance Xen becomes LF Collaborative Project 2003 2004 2005 Developer list traffic : Q3 2003 - now 2006 2007 2008 2009 2010 2011 2012 2013

  • 16. Theory: vendor neutrality = more contributors Early indicators: Individual Contributors have doubled Advisory Board members are becoming contributors Momentum in new market segments is building Advisory Board is developing a long term project Vision Creating incentives to become more mature
  • 17. Created “pain for distros” Inwards focus – Not working with upstreams (branched kernel and QEMU) – Not working with distros (users are not “our” problem) Intercommunity Friction Introvert Community Image Problem
  • 18. Linux Host support for Xen Upstream QEMU complete Linux Guest support for Xen IBM, VMware, Red Hat and Citrix Agree on PVOPS in Linux kernel Actively working with distros 2003 2004 2005 Developer list traffic : Q3 2003 - now 2006 2007 2008 2009 2010 2011 2012 2013
  • 19. Improved Relationships & Trust Xen Developers Care about Users Xen becoming easier to use Improved Image in the media and FOSS community
  • 20. Significant increase in Goodwill from the LINUX community Working with upstream & downstream projects is easier Collaboration happening earlier than in the past Automotive, Mobile, Embedded
  • 21. Empty Promises Change of Guard Focus on events for the existing community only Blog Enough Papers Enough Talks Enough Communication By enough vendors 1 Person Competing Projects Excelled at Communication 2003 2004 2005 Developer list traffic : Q3 2003 - now 2006 2007 2008 2009 2010 2011 2012 2013
  • 22. Project became an “invisible man” Belief that Xen is not open source Slowed the growth of the user base Perception: the project is “dead” Constant stories in the press that the project is dying First: Defiance – this is all “Fud” Then: Project started to believe this too

  • 28. Community Companies
  • 29. Within Citrix : via the process of “giving up control” Big enough plan to catch the attention of senior management Forced decision makers in the hierarchy to consider the value of F/OSS Amongst companies supporting the project financially Forced decision makers in contributors to go through a similar process
  • 30. Governance and Neutrality Matter Projects don’t exist in isolation Poor Marketing and Communication can kill you Good project sponsors can make a difference Being part of a Foundation can make a big difference A project needs to constantly evolve
  • 31. License & Development Model Linux (but also BSDs) are key components in a Xen stack Most Xen contributors were Linux Foundation members Vendor Friendly Strengths: PR, User Outreach, Events Management, …
  • 32. Multi-discipline Complexity
  • 33. Follow Industry News Follow Project News Trial Software Think of the funnel boundary as a permeable membrane, not a fixed border Adopt Software Engage with Users It can take >2 years for changes at the top of the funnel to make a difference at the bottom Engage with Industry Evangelize Customize Contribute Lead The Funnel has feedback loops: what happens at the top can affect the bottom
  • 34. Project Scope Follow Industry News E.g. Xen on ARM, Mirage OS Increase the width and thus the potential market for the project Follow Project News Trial Software Activities Attributes Events Adopt Software Control the permeability and shape of the funnel Engage with Users Some items are in your control Others - such as what the competition does - are not! Engage with Industry Evangelize Customize Contribute Lead How can we influence how the Community Funnel works?
  • 35. Follow Industry News Follow Project News Trial Software Adopt Software On-boarding Documentation Ease of Use Engage with Users Training Engage with Industry Evangelize Customize Contribute Lead Example: Factors influencing early stages of open source software adoption
  • 36. Follow Industry News Bad Press Follow Project News Trial Software Funnel becomes narrower Adopt Software More People drop out Engage with Users Engage with Industry Evangelize Example: Negative feedback loop Customize Contribute Lead Negative Feedback: vendors may stop contributing
  • 37. The Community Funnel is an excellent internal sales tool Reason: Sales and Business people understand funnels It helps you understand what is happening It helps prioritize what to focus on Covers the time dimension : some issues take longer to fix than others Forces you to consider the “Big Picture”
