How to check if the Processor (CPU) supports the function SLAT?

Among the many new features of Windows 8, there is the integrated virtualization using Hyper-V hypervisor and manages virtual machines natively in Windows. To take advantage of the function SLAT (Second Level Address Translation) present in some processors is mandatory. This How-To guide will help you to find out if your CPU is compatible with SLAT.

Virtualization will be the heart of Windows through the integration of the Hyper-V. This will make it possible to create virtual machines for Windows 8 where you can run operating systems known as “guests” from Windows 8. This will make it possible to find Windows XP, Windows Vista or Windows 7 and your old software directly from a Windows, Linux distributions to run or even to run critical applications in a virtual machine without risk to your system. This will allow you to easily

  • create 32 or 64 bits virtual machines for other operating systems directly from the explorer from ISO or VHD images,
  • adjust on the fly the amount of RAM allocated to your virtual machines,
  • connect remotely to a virtual machine and use your hardware like USB, printer, scanner, speakers and many other devices.
  • backup function will also restore the state of a virtual machine at desired time.

What are prerequisites for SLAT?

  • To use the Hyper-V Windows 8, there will be some technical prerequisites.
  • 64-bit version of Windows 8 is mandatory
  • Minimum 4 GB of memory
  • CPU that supports the function SLAT (Second Level Address Translation).

To check if your processor supports virtualization and therefore SLAT Windows 8, you can use free software CoreInfo. CoreInfo is currently available for download at Microsoft website so before you start to follow below steps make sure you download CoreInfo installation files.

  1. Download CoreInfo installation file on the Microsoft site (0.338 MB).
  2. Once the download completes, locate installation file and copy that same file in root of C: drive.
  3. Once copied double click on installation file and install it.
  4. Click I Agree in the window that opens.
  5. Once installation is done lick the windows Start button and inside search field type cmd and comfirm with Enter.
  6. Return to the root of C: drive by typing cd c: and confirm with Enter.
  7. Now type the command coreinfo -v and confirm with Enter.

Now, based on the results you get how to know if you processor (CPU) supports SLAT?

On an Intel processor, a star (*) on the line EPT means that SLAT is supported.

On an AMD processor, a star (*) on the line NP means that SLAT is supported.

AMD Processors results that show it sipports SLAT

If a dash is on the line EPT or NP, then your processor does not support the function SLAT and you cannot use Windows 8 Integrated Virtualization. The only thing you can do is to buy a new Processor but remember it needs to be 64-bits version.

    I am trying to verify that to check SLAT is supported or not, but every time it shows Administrator rights are required to query Intel virtualization support. So please how can I rectify this.
