LCEU13 : Xen Project Lessons Learned - Lars Kurth, Xen Project
May 19, 2015
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.

Individuals & Hobbyist's Still about Individuals
But, a majority are employees
Companies have a huge stake

How many users you have
How many vendors back you
How you are seen in the press

Neutrality / Perception

all the right things
Case Study
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
Fixes that were applied (there may be others)
Effect this had
Magnifying effect
Symptoms Consequences for Xen
Four Key Issues
At the end : Reflection & Tools
Unwritten Rules Undefined Roles Lack of Upfront Collaboration
Hard to join the project Vendors got frustrated Hard to work with the project

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
Inwards focus
– Not working with upstreams (branched kernel and QEMU)
– Not working with distros (users are not “our” problem)
Created “pain for distros”
Intercommunity Friction
Introvert Community
Image Problem

IBM, VMware, Red Hat and Citrix
Agree on PVOPS in Linux kernel
Linux Guest

Improved Relationships & Trust
Xen Developers Care about Users
Xen becoming easier to use
Improved Image in the media and FOSS community
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

Developer list traffic : Q3 2003 - now
Focus on events for the existing community only
Enough Papers
Enough Talks
Enough Communication
By enough vendors
Competing Projects Excelled at Communication
Change of Guard
Empty Promises
Blog 1 Person
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

Press clips
Companies Community
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
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
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, …

Think of the funnel boundary as a
permeable membrane, not a fixed
border
It can take >2 years for changes at
the top of the funnel to make a
difference at the bottom
The Funnel has feedback loops:
what happens at the top can affect
the bottom

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”

NOW (areas that so far benefited from being in the Linux Foundation)
To succeed, a wide range of “community” and “management” tools
need to be applied continuously
