MS, Intel "Goofed Up" Win 7 XP Virtualization

clang_jangle writes "Ars Technica has a short article up describing how Microsoft and Intel have 'goofed up' Windows 7's XP Mode by ensuring many PCs will not be able to use it. (And it won't be easy to figure out in advance if your PC is one of them.) Meanwhile, over at Infoworld, Redmond is criticized for having the 'right idea, wrong technology' with their latest compatibility scheme, and PC World says 'great idea, on paper.' With Windows 7 due to be released in 2010, and Redmond apparently eager to move on from XP, perhaps this is not really a 'goof' at all?"

    The solution Microsoft is adding to Windows 7 is the same solution Apple used for the OS 9 - X transition. Classic was a second operating system that ran essentially as a virtual machine.

    When running Linux, open up a terminal and run this:
    echo -n "Does my cpu support virtualizaiton? "; if `cat /proc/cpuinfo | grep -q svm || cat /proc/cpuinfo | grep -q vmx`; then echo Yes; else echo No; fi

    Another issue you may have is if your system has the virtualization functions disabled in BIOS. Some laptops do this, and have no way to turn them on. My Dell D820 works fine.

      This is even easier:

      egrep -q "(svm|vmx)" /proc/cpuinfo && echo yes || echo no

    The parent isn't insightful, because he erroneously believes that a new machine guarantees that virtualization will be available. Not so.
    Buy a $3000 Sony Vaio-Z, for example, and despite it having a chipset and a brand spanking new Core 2 Duo CPU that both supports VT-x, the manufacturer has chosen not to give the users the ability to turn it on in the BIOS, so it doesn't help one bit.

    That suite of applications that you're testing doesn't accurately represent the target population for XP emulation.

    XP Emulation is primarily geared towards businesses with legacy/custom business applications which have not been re-written for Windows Vista/7.

    We run an ancient version of Televantage here.

    The Televantage server itself is still running NT4. The client software refuses to run on anything newer than Windows XP SP1.

    The solution has been to go ahead and update our machines to SP2/SP3/Vista/whatever and run Televantage inside a small virtual machine running Windows 2000 SP4 - it works great.

    This is the kind of problem the XP-mode is intended to address.

    Indeed they don't. Apart from the BZ-series, all Sony Vaio PCs have VT-x disabled, and no way to turn it on in the BIOS setup. Even if you buy a brand new Core 2 Duo P9600 Vaio Z with 4 GB RAM for 2-3000 bucks, it won't be an option.

  6. No Virtualization on some new Intel by clarkn0va · · Score: 4, Informative

    AC obviously didn't read the article, which states clearly that Intel uses VT availbility as a market segregation tool.

    A recent example would be the new Core 2 Quad Q8400, now with less VT!

    IMPORTANT: The RC will expire on June 1, 2010. Starting on March 1, 2010, your PC will begin shutting down every two hours. Windows will notify you two weeks before the bi-hourly shutdowns start. To avoid interruption, you'll need to rebuild your test machine using a valid version of Windows before the software expires. You'll need to rebuild your test PC to replace the OS and reinstall all your programs and data.
