unable to run windows 8.1 preview in virtual box RRS feed

  • Question

  • hi , 

    I have core i5 , 3GB ram in my laptop and 512 mb grpagic card.

    i am using windows 8.

    I downloaded window s8.1 and installed virtual box and when i start the machine of windows 8.1 in virtual  box , i get this errir

    VT-x/AMD-V hardware acceleration is not available on your system. Certain guests (e.g. OS/2 and QNX) require this feature and will fail to boot without it.

    when i continue it to ignore then i get error in windows 8.1 that this processor doesnt support 64bit applications.


    Thank You , Shan Ali Khan

  • Use VirtualBox 4.2.16 which fixes the issue. Make sure you select the 8.1 template.

  •   If you do not have hardware virtualization you cannot run a 64-bit guest in VirtualBox.

  • In order to install and use Windows 8.1 preview/Windows Server 2012 R2 preview in VirtualBox, you have to run this command:

    CODE: Select all Expand view

    "c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "VM Name" VBoxInternal/CPUM/CMPXCHG16B 1

    You can see your VM names using this command:

    CODE:  Select all Expand view

    "c:\Program Files\Oracle\VirtualBox\VBoxManage.exe"  list vms
