Enhanced ARM support and stronger scalability for cloud computing servers highlight the long list of new features in Xen 4.4, the open source virtualization hypervisor whose release the Linux Foundation has announced.
Xen offered some ARM support before, but it is much more comprehensive in the latest version. Now, the hypervisor supports all of the following ARM platforms: AppliedMicro’s X-Gene, the Arndale Board, Calxeda ECX-2000, TI OMAP5 and the Allwinner SunXi boards. It also features support for 64-bit guests on ARMv6 systems, as well as userspace tools for creating and managing virtual machines that are “64-bit ready” in ARM environments.
