The Xen Project is an open source virtualization platform licensed under the GPLv2 with a similar governance structure to the Linux kernel. Designed from the start for cloud computing, the project has more than a decade of development and is being used by more than 10 million users. As the project experiences contributions from an increasingly diverse group of companies, it is looking to The Linux Foundation to be a neutral forum for providing guidance and facilitating a collaborative network.
