The Xen ARM Project, maintain an ARM variant of the Xen Hypervisor in a codeline that is separate from
the upstream Xen Hypervisor project. The Xen ARM Project is led by Samsung,
and delivers and maintains Xen support for a range of ARM processors (ARM v5 - v7) for mobile devices, using
Xen Paravirtualization (PV).
The project is also working on problems such as solving real-time guarantees in a virtualized environment and multi-processor
support. The project is led by Sang-bum Suh from Samsung and
can be monitored on the Xen ARM Wiki or the project
With the introduction of virtualization
extensions on ARM processors, the Xen community has taken steps to add ARM support for ARM CPUs to the
Xen Hypervisor. This port is executed as part of of the Hypervisor project, with no separate codebase.
