In 2007 Citrix acquired XenSource gaining control over the development of the Xen Hypervisor part of the Xen project. Today Citrix announced that it will hand over the Xen Project to the Linux Foundation which will continue its development. After both Ian Pratt and Simon Crosby who came from XenSource left Citrix to start their company Bromium, Citrix has clearly been struggling on how to continue its involvement in the development of the Xen project, leading to this decision.
The following companies will contribute to and guide the Xen Project as founding members of the Collaborative Project at The Linux Foundation: Amazon Web Services, AMD, Bromium, Calxeda, CA Technologies, Cisco, Citrix, Google, Intel, Oracle, Samsung and Verizon.
Its interesting to note that the Linux Foundation also supports the Kernel-based Virtual Machine (KVM) development, the hypervisor included in Linux. Perhaps we can see some joint development towards a new hypervisor in the future, this remains to be seen ofcourse.
Xen.org will be moved to Xenproject.org the new home of the project.
