Teams and Projects¶

The Xen Project is made up of several sub-projects, each with their own maintainers, repositories, and contribution workflows. This page gives an overview of the main teams and how to get involved with each.

Xen (Core hypervisor)¶

The Xen hypervisor itself is the core of the project. Development takes place on the xen-devel mailing list and patches are submitted by email.
