    We are pleased to announce the first stable release of the Xen
    virtual machine monitor for x86, and port of Linux 2.4.22 as a
    guest OS.

    Xen lets you run multiple operating system images at the same
    time on the same PC hardware, with unprecedented levels of
    performance and resource isolation. Even under the most demanding
    workloads the performance overhead is just a few percent:
    considerably less than alternatives such as VMware Workstation
    and User Mode Linux. This makes Xen ideal for use in providing
    secure virtual hosting, or even just for running multiple OSes on
    a desktop machine.

    Xen requires guest operating systems to be ported to run over
    it. Crucially, only the kernel needs to be ported, and all
    user-level application binaries and libraries can run
    unmodified. We have a fully functional port of Linux 2.4.22
    running over Xen, and regularly use it for running demanding
    applications like Apache, PostgreSQL and Mozilla. Any Linux
    distribution should run unmodified over the ported kernel. With
    assistance from Microsoft Research, we have a port of Windows XP
    to Xen nearly complete, and are planning a FreeBSD 4.8 port in
    the near future.

    Xen is brought to you by the University of Cambridge Computer
    Laboratory Systems Research Group. Visit the project homepage to
    find out more, and download the project source code or the
    XenDemoCD, a bootable `live iso' image that enables you to play
    with Xen/Linux 2.4 without needing to install it on your hard
    drive. The CD also contains full source code, build tools, and
    benchmarks. Our SOSP paper gives an overview of the design of
    Xen, and evaluates the performance against other virtualization
    techniques.

    Work on Xen is supported by UK EPSRC grant GR/S01894, Intel
    Research Cambridge, and Microsoft Research Cambridge via an
    Embedded XP IFP award.
