Red Hat Enterprise Linux and Novell's Suse Linux Enterprise Server both use the Xen virtualization software, a "hypervisor" layer that lets multiple operating systems run on the same computer. In contrast, the KVM software runs on top of a version of Linux, the "host" operating system that provides a foundation for other "guest" operating systems to run in a virtual mode.

.. by K/Ubuntu, especially if KVM can furnish most features & capabilities available in Xen, VMWare and the likes.

This will easy and simplify the migration process from Windows to Linux on the desktop. More importantly in the enterprise where lack of Windows applications is a huge show stopper.

I never used before and I can't wait to test it and show it.

Any one has experience with it to share?

I think the article got it right. I used (and still do) KVM and VirtualBox on a workstation to test or support other OSs (like Ubuntu in a virtual machine on my Etch or so).

On a server, it depends. If it's only hosting (read: virtual machines or even containers only for web, mail, and so forth), I would use something like linux-vserver. In fact, all of my web presences are based on those.

But for really heavy duty stuff, or for running several different operating systems aside each other, it's definitely Xen. And that seems to be a common approach.
