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This project has been inactive since 2012 and been superceded by the newer Xen ARM PVH project in the Xen Hypervisor mainline. First support for ARM PVH has been available in Xen since Xen 4.3 (July 2013). We have also seen the first mobile demos on showing Android running on Xen using the newer and very active Xen ARM PVH project: Also see Category:Android and Category:Embedded. The code for the original Xen ARM (PV) port is and ill be available, but it is likely that almost all development effort will happen on the newer Xen ARM PVH.

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.
