Xen support in mainline Linux kernel

For the past two years, Xen infrastructure has been getting included in the Linux kernel piece by piece. It's finally done. A nice coincidence is that new version we'll be called 3.0 instead of  2.6.30  2.6.40 - just like Xen was the feature so important it justified the change (in reality, there was no single large addition, just the sum of small changes since 2.6.0 made today kernel something completely different).

Soon an ordinary Linux system will be able to run as Xen dom0 (host) without any changes in the kernel, just like it is with KVM, VirtualBox and some other virtualization solutions. I hope it will stop the decline of Xen: when it's no harder to setup then its competitors and offers better performance, it's becoming and interesting choice again.
