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. The fantastic news is that Linux 3.0 will have everything necessary to run Xen as both as a management domain and as a Xen guest. You can find more information in the following two posts

A big thank you to everybody in the community who helped make this happen. To conclude let me quote from Wim’s blog post, as it captures really well what this means for our community!

“All this means that every single bit of support needed in Linux to work perfectly well with Xen is -in- the mainline kernel tree. 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.
