    I am forced to spend quite a bit of time with my only relatively
    powerful workstation booted into XP so I can do CAD work
    (unfortunately Autodesk's Inventor only runs on Windows). Because of
    this unfortunate situation I am planning my first attempt to get the
    Linux install that I have on the other drive in this workstation to
    boot using VMware. VMware has the ability to access raw disk
    partitions (as apposed to partitions stored in a file on a host
    partition) so I figure with some init and /etc magic I should be able
    to boot the system using VMware and when I am not drawing in Inventor
    I should be able to reboot and run Linux natively directly on the
    hardware.

    What I am wondering is what I/O scheduler should I be using when the
    system is running within a VMware instance? I figure that Windows
    will be scheduling the access to the physical hardware so I would
    assume that I want a bare bones priority based scheduler, something
    with the lowest possible overhead. Is this correct? If so, what
    would that scheduler be?

    IIRC someone (Ingo?) was working on the ability to change schedules
    during runtime. How has that work progressed? Is it available in any
    kernel trees?
