InfoWorld's Test Center picks the best open source software for agile infrastructures in 2011
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.
