Yeah, according to eWeek, RedHat wants Xen to be part of the Linux kernel.

My point of view, if anybody cares, is that it's a good point for us. Virtualization (or supervision, call it as you want to) is a new battle coming in our little world.
Why? Because it's the new easy way to secure and handle big and/or complex information system infrastructure and architecture in a cheaper way. No more need of many boxes dedicated to one job, just a few, and run as many as you want different OS and isolate them. The second argument is the possibility to manage workload flows, migrate then, freeze them and so on, in a transparent way. That's why virtualization is great and powerful in some way and because you will love it.

Yeah, I confess, I love Xen, because it works.

And finally, we don't want Microsoft to have this argument on its side only. ;-)
