About Xen Virtualisation

Xen is a virtualisation technology for x86 processors, that supports the execution of multiple operating systems on a single hardware platform. Xen virtualization provides many exciting benefits over traditional single OS computers, including live server migrations, server consolidation, application mobility and secure computing. What sets Xen apart from other virtualization technologies, however, is its performance. In fact, running over Xen, Linux's performance in a variety of benchmarks is consistently close to native Linux. Xen is widely supported in the industry, with significant investment by Intel and AMD. Xen was developed at the University of Cambridge computer laboratory and is open source software, released under the terms of the GNU General Public License.
