    Hi all,

    While reading an article today, I stumbled across the Xen project, which I
    suppose is something like an open source VMWare. Could be interesting for
    the hosting providers among you.

    From their page (http://www.cl.cam.ac.uk/Research/SRG/netos/xen/):

    Modern computers are sufficiently powerful to use virtualization to
    present the illusion of many smaller virtual machines (VMs), each running a separate operating system instance. Successful
    partitioning of a machine to support the concurrent execution of multiple
    operating systems poses several challenges. Firstly, virtual machines must
    be isolated from one another: it is not acceptable for the execution of
    one to adversely affect the performance of another. This is particularly
    true when virtual machines are owned by mutually untrusting users.
    Secondly, it is necessary to support a variety of different operating
    systems to accommodate the heterogeneity of popular applications. Thirdly,
    the performance overhead introduced by virtualization should be small.
    Xen is a virtual machine monitor for x86 that supports execution of
    multiple guest operating systems with unprecedented levels of performance and resource isolation. Xen is Open Source software, released under the
    terms of the GNU General Public License. We have a fully functional ports of Linux 2.4 and 2.6 running over Xen,
    and regularly use it for running demanding applications like MySQL, Apache
    and PostgreSQL. Any Linux distribution (RedHat, SuSE, Debian, Mandrake)
    should run unmodified over the ported OS.
    In addition to Linux, members of Xen's user community have contributed or
    are working on ports to other operating systems such as NetBSD (Christian
    Limpach), FreeBSD (Kip Macy) and Plan 9 (Ron Minnich). A port of Windows
    XP was developed for an earlier version of Xen, but is not available for
    release due to licence restrictions.
