    Default Xen processor support?

    Hi,

    I tried to use Xen on openSuSe 11.1 but it said no processor support (I'm running Intel Core 2 Duo T5800).

    What processors from Intel Core range are supported?
    Is it possible to run virtualization on T5800?

    hi,

    AFAIK this processor support Xen. But I think that this is controlled by a bios setting something like "Enable VT" and I have see that even for server this option is mostly deactivated. So look in all options of your bios

    Good luck

    The problem is that if you do not enable vt in your BIOS then you will not
    be able to run it in hardware only software mode, now I am going on my
    experience with Virtualbox and an AMD chip here, not 100% sure on the Intel
    architecture or Xen.

    But the AMD`s were the first to have a dedicated part of the CPU just for
    the Hypervisor ( special bit for virtualisation ) and unless you have this
    enabled you will only get software mode which is a lot slower than hardware.

    If Xen will not run in software mode then you will have to enable it in the
    BIOS you will notice any slow down in any other applications or any
    detrimental effects from this at all.

    Unless you are trying to do this on a Sony laptop which has been found out
    that some do not have the option in the BIOS to enable it even though it is
    there.

    Ref.

    So if you cannot or will not enable it and Xen will not run in software mode
    then try virtual box ( in the repos ) or grab from their site and run in
    software mode but expect a much slower virtual environment.

    No mention of my processor..... so I assume it is not supported. Correct me if I'm wrong. I just don't want to waste time on reinstalling everything just to find out that it does not work... I lost all weekend last time...

    Hi
    I checked on the Intel site and there I found that the core 2 duo t5800 has no VT. So Xen should not work
