    /proc/cpuinfo on a Dell 6650 shows the machine as having 8 CPUs
    (numbered 0 through 7). Its running AS version 3 and kernel is
    2.4.21-27.ELsmp

    The machine has the maximum of 4 CPUs actually. Is this a bug or am I
    not reading the file correctly?

    Thanks for any leads

    We recently picked up a new SGI Altix 350 (2 bricks, 4 cpus, 4GB) for
    "playing around", although it will hopefully become a part of our
    corporate development environment. It came installed with SuSE 9 SLES
    (which I'm not very fond of) and some Red Hat Enterprise for Itanium
    CDs, which I'd like to install in it. I'd like to do some sort of
    virtualization, a la Xen, to allocate virtual systems to various
    developers, but I'm not finding much that will run on the Altix 350 in
    32-bit mode with SMP, much less ia64.

    Has anyone run Xen on *any* flavor of Linux running on Altix (in
    particular, Red Hat/Fedora-based)? Any suggestions or ideas?

    I went to a couple of Xen presentations at the Red Hat Summit in early
    June. The comment there was that x86 32bit was mostly working now but
    that x86_64, ia64, amc ppc64 were "still in flux".

    Rik van Riel also said that Xen 3.0 was "not stable yet but in Fedora
    Core 4". He expected 1-2 months for a feature freeze and 3-4 months
    before it got stable.

    Intel has 30 developers working on Xen according to the Intel keynote.

    I don't know if VMware supports the ia64 yet - from a quick look at
    their web site, they didn't in VMware 4 but they're not really saying if
    it's supported in VMware 5.

    There is a mailing list for Xen discussions - you could try there.
