Xen enhances support for ARM

ARM on servers, running virtual machines, will soon be a reality and companies are preparing themselves for it. Open Source, as usual, has a lead in this domain and now Linux Foundation hosted Xen Project has strengthened its support for ARM.

“Virtualization and low-powered servers are leading companies to rethink the data center and its potential for efficiency,” said Lars Kurth, Chairman of the Xen Project advisory board.

The project has announced Hypervisor 4.4 with improved ARM support. There are major companies behind this release which include AMD, Citrix, Intel, Oracle and SUSE.

Newly supported hardware include AppliedMicro’s X-Gene, the Arndale Board, Calxeda ECX-2000, TI OMAP5 and the Allwinner SunXi boards.

The project says, “The substantially improved multiplatform capabilities of the hypervisor allow hardware and embedded vendors to port the Xen Project technology to new ARM SoCs easily, shortening their time to market.”

The new release introduces significant stability, usability and performance improvements for the ARM architecture and extended hardware compatibility. AppliedMicro’s X-Gene, the Arndale Board, Calxeda ECX-2000, TI OMAP5 and the Allwinner SunXi boards are all supported. The substantially improved multiplatform capabilities of the hypervisor allow hardware and embedded vendors to port the Xen Project technology to new ARM SoCs easily, shortening their time to market.

Additional enhancements in this release included 64-bit guest support on ARMv8 platforms. All userspace tools, such as the xl management tool, can run on 64-bit and create 64-bit virtual machines out of the box.

The release also include 64-bit guest support on ARMv8 platforms. The Xen Project hypercall ABI is now stable and will be maintained for backward compatibility, so users can trust future releases to boot older operating systems.
