Xen 3.3.0 Available For Download

A recent post on the Xen blog featured a proposed data sheet (PDF) for the (back then upcoming) Xen 3.3 release, which we said was in final testing stage in the beginning of this month. Now Xen 3.3.0 is here and ready for download, as reported by Heise Online.

The new version is also available as part of a package with a 2.6.18 kernel version of Linux as the host system, also known as Domain 0 (Dom0). According to Xen developers, the number of supported guest operating systems has grown and there are improvements in performance, the ACPI power management modes, and security functions such as using PVGrub instead of PYGrub. Xen 3.3.0 also has fewer limitations on moving running virtual machines from one physical system to another. This function, necessary for redundant fail over configurations and practical for server maintenance, has previously only been usable when the processors (and chipsets) running on the physical machines involved supported very similar hardware virtualization functions.
