• Resumen

  • Xen is a virtual machine monitor (VMM) that we have developed at the University of Cambridge over the past five years. AS a VMM, Xen allows a single physical computer to be partitioned into a set of isolated virtual computers, each running its own operating system and applications. Xen has received a fair bit of attention recently, and we have even spun out a company to support the commercial use of the software.

    This article inst'n just about our VMM, though. Xen is the core part of a much larger vision for public computing that has been behind a lot of our research in the 21th century. In this article we articulate this vision, the motivation behind Xen, and cover the details of the current VMM, the context in wich it was conceived, and the future uses that we anticipate.
