Problems installing 64 bit virtual machine OS RRS feed

  • Question

  • Hello, still trying to get more familiar with virtualization but currently my physical machine is running Windows 7 Enterprise 64 bit and when I set up a virtual machine via Windows Virtual PC and then point it to install a Windows 2008 Server 64 bit OS .iso file it shows the following error in the guest vm:

    Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.

    I ran the 64 bit machine checker utility file and it confirmed my physical machine can support 64 bit os guest vms.  In looking around I've even tried to update my physical machine's BIOS to enable virtualization but still get this error message and can't install a 64 bit OS on a guest vm.  I can get Windows 2008 Server 32 bit up as a guest vm but how can I get any 64 bit OS guest vm up & running on my physical machine?  Thanks in advance.

  • Windows Virtual PC does not support 64-bit Guests

    If you want to work with 64-bit guests on Windows 7, you will need either VMWare or Oracle Virtual Box.

  • That's what I kind of suspected. Thanks Bill, much appreciated :)

    Have a look at my solution to the above.
