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 the key challenges the project had under Citrix' stewardship, explain why Xen moved to the Linux Foundation, explore the challenges and considerations when choosing an open source foundation and explore the impact on the Xen community to date. The talk will centre around the core question of whether open source foundations provide a better collaboration platform for open source projects than corporate stewardship. The answer - at least for the Xen project - is clearly yes. However, following this route has its own challenges, trade-offs and risks.
