Linux Kernel Goes Virtual: A Challenge to Xen?

While many Americans were focused on the sports spectacle known as the Super Bowl last Sunday, Linus Torvalds was focused on releasing a new Linux kernel.

Version 2.6.20 of the kernel includes a bevy of fixes and features, notably the introduction of KVM (Kernel-based Virtual Machine) virtualization to the mainline kernel (define).

KVM virtualization in Linux 2.6.20 could potentially challenge open source virtualization specialist Xen, which has been aiming for Linux kernel inclusion for nearly two years. KVM was created and is maintained by technology start-up Qumranet.
