    Virtualisation in Intel Core Duo machines not switched on

    So don't get too excited

    By INQUIRER staff: Thursday 02 February 2006, 08:35

    PEOPLE RECEIVING machines which use Intel's Duo Core machines will not be able to take advantage of its VT virtualisation technology for some time.
    A reader who has ordered and received one of the new Dell Centrino machines using Duo Core noticed that while there's a virtualisation option in the BIOS, it does nothing when you switch it on.

    There's a reason for this. VT for the T2600, the T2500, the T2400 and the T2300 isn't yet implemented, according to recent roadmaps seen by the INQ.

    We understand that Intel, or rather the manufacturers of the machines, are likely to offer a BIOS flash but that's unlikely to arrive until the second quarter of this year.

    The T2700, the top end Intel Duo Core processor which clocks at 2.33GHz, will have VT switched on when it ships.

    But the T2700 is not due to ship until the second half of this year, as previously reported. As we have repeatedly pointed out, Yonah Dual Core processors are 32-bit CPUs - it won't be until Intel's Merom is launched that 64-32 processing will be implemented.

    Not that this matters much - as users of AMD Turion 64-32 machines know, driver support for 64-32 bit CPUs is rather inadequate. Perhaps Vista will improve this situation. µ

    Virtualization Technology is the name of the mutually incompatible virtualization technologies from Intel and AMD, previously known by their respective codenames "Silvervale" and "Pacifica". They allow a single machine to run multiple operating systems at once without incurring significant emulation costs.

    The following software is known to conditionally make use of virtualization technology features:
    Microsoft Virtual PC
    Microsoft Virtual Server — a future version (after Virtual Server 2005 R2) will support Intel VT and AMD Pacifica extensions.
    Parallels Workstation - lightweigh hypervisor with Intel VT-x support
    VMware — on Intel processors, VMware Workstation 5.5 requires Intel VT to execute 64-bit guests.[1]
    Xen — Xen 3.0 uses Intel VT to execute unmodified guest operating systems.

    It may be supported by EFI though. So it could be on already with x86 Macs.

    Are there any VT software for x86 Mac OS X yet?

    They are saying it's not implemented in the CPU.
