  User Mode Linux: multiple instances/distros, simultaneously/cheaply/safely

    Have you ever wanted to run Debian Linux and Slackware side by side?
    Or, how about Red Hat Linux and Suse? Why not all of them at the same

    Traditionally this wasn't possible. You would need to boot each Linux
    OS one at a time to use them. Or you would need to purchase multiple
    computers to run all the different Linux distributions simultaneously.
    For obvious reasons this is not affordable, practical, etc. Today that
    is no longer the case, thanks to dedicated Linux kernel hackers and
    the ample capabilities of the Linux kernel: It is now possible to
    "virtualize" the Linux kernel with User Mode Linux.

    Short version: User Mode Linux virtualizes the Linux kernel so that
    you can run Debian, Slackware, Redhat, Suse, and any other distro all
    at the same time on a single machine!

    Long version: User Mode Linux engages in a very efficient form of
    virtualization that directly modifies the Linux kernel so that the
    kernel is able to be run as a normal executable. Essentially this
    allows one to spawn many different User Mode Linux instances on a
    single machine. Once you add some basic networking and file system
    support (all provided by any basic Linux kernel), you have a full
    blown virtualization environment that allows you to run as many
    distributions as you want. Arguably it doesn't get cooler than this.

    Real world uses for User Mode Linux. Hosting: No longer do you have to
    shell out big money to run your own (physical) server. Instead find an
    enlightened User Mode Linux provider and enjoy the savings of running
    virtual Linux servers a la UML way. Kernel testing: No longer do you
    have to have to actually boot into a kernel to test a patch, rather
    test it with the ease of User Mode Linux, with minimal risks to your
    real workstation/server.

    BONUS! During the meeting, all attendees will receive a CDROM
    containing all the User Mode Linux software, documentation, and custom
    made Linux distribution images they need to get started in the comfort
    of their own homes! Come and enjoy this presentation.
