Konrad Rzeszutek Wilk, Software Development Manager at Oracle, and a Xen Project advisory board member, told ServerWatch that in the new Xen 4.4 release ARM support is no longer experimental and has matured significantly with major usability and performance improvements.
“The hypercall ABI is stable and will be maintained for backward compatibility,” Wilk said. “This means that going forward, kernel communication to the hypervisor will be supported in this fashion.”
Wilk added that in the ARM world, hardware compatibility is often a challenge. To that end the Xen project has done the hard work to add support for AppliedMicro’s X-Gene, the Arndale Board, Calxeda ECX-2000, TI OMAP5 and the Allwinner SunXi boards.
