For the ARM port for processors with hardware virtualization extensions see Xen ARMv7 with Virtualization Extensions.

Xen ARM PV Project

Xen-ARMPV is called originally Secure Xen on ARM which consists of Xen on ARM VMM and the associated access control.

This project has been inactive since 2012 and been superceded by the newer Xen on ARM (with virtualization extensions) project or short Xen on ARM project. The code created by the Xen on ARM project has been merged into the Xen Hypervisor mainline and is maintained as part of the Xen Hypervisor (unlike the Xen ARM PV project, which forked Xen and Linux). First support for ARM has been available in Xen since Xen 4.3 (July 2013). We have also seen the first demos showing Android running on Xen 4.3 using the newer and very active Xen on ARM port. Also see Category:Android and Category:Embedded. The code for the old Xen ARM (PV) port is and will be available from this page, but it is likely that almost all development effort for ARM will happen on Xen on ARM in the Xen mainline (and not in the Xen ARM PV fork).

Current Status

Secure Xen on ARM supports the ARMv7 architecture family, specific platform we test/run on is:

• nVidia Tegra250 Development Board

Note : This release does not support all architectures prior to ARM v7. Previous versions of Xen-ARM can be found on the Xen-ARM archives section.

• Note that Xen ARM is currently rebased onto xen-unstable such that it can be upstreamed. The work is currently performed on Jaemin Ryu's personal branch

Jaemin Ryu's personal another branch, target on tegra250 board

Xen-ARMPV source

Please follow Xen ARM PV Repo and Jaemin Ryu's personal branch.
