Xen celebrates full Dom0 and DomU support in Linux 3.0

This is a very short blog post as both Wim Coekaert and Ewan Mellor beat me by some time in publishing this great news: I was too busy traveling and celebrating.

I’ve heard over the last few years, competitors use “There is no Xen support in Linux” as a tagline to create fud with the Xen userbase and promote alternatives. Well, it’s all there people. As Linux evolves, now, within that code base, the Linux/Xen bits will evolve at the same rate without separate patch trees and big chunks of code to carry along. This is great, Xen is a great hypervisor with capabilities and features that one cannot achieve in a non-true hypervisor architecture.
