Congratulations to the community for winning the 2011 BOSSIE Award in the Data Center and Cloud Software category. BOSSIE Awards are given to the best open source software in several categories. The first BOSSIE Awards were announced in September 2007 and the awards are adjudged by the InfoWorld editors and reviewers. Xen has won the BOSSIE Award in the Hypervisor and Server Virtualization category in 2007, 2008 and 2009. It is great to have won this year!

Let me quote what InfoWorld says about Xen:

The open source world offers two terrific hypervisors in KVM and Xen. KVM has had the advantage of residing natively in the Linux kernel, eliminating the need for mods or patches and reaping the benefits of the underlying Linux APIs. As a result, KVM took the Bossie last year. But that was then, and this is now.

In May of this year, Xen joined KVM in the Linux mainline. Now all of the code necessary to run Linux as the Xen management OS and as a paravirtualized Xen guest is part of the Linux kernel itself. The milestone puts Xen on an equal footing with KVM in terms of keeping pace with changes to Linux. It also represents a significant achievement of the Xen team and earns our Bossie.

Of course there’s still work to be done. Managing Xen can daunting enough to send you in search of a commercial tool such as Citrix’s XenServer. But thanks to Xen’s early foothold in server virtualization, you’ll find a good ecosystem of tools to help with provisioning, monitoring, and security.

Thanks to everybody in the open source community for all the good work, and keep at it! I am particularly excited about projects such as project Kronos, which should make a big difference to users of open source Xen.
