In order to use the new virtualization service in Windows 8 your processor needs to support a feature referred to as Secondary Level Address Translation (SLAT). Without SLAT, you will not be able to add the Hyper-V service to your host, so it would be helpful to know if you have this available or not.
This article from How-To-Geek ( http://www.howtogeek.com/73318/how-to-check-if-your-cpu-supports-second-level-address-translation-slat/ ) will explain more about SLAT and how to download a great tool from Mark Russinovich called CoreInfo. This tool gives you the information you need to see if your processor supports SLAT. Here is the direct link to his download, http://technet.microsoft.com/en-us/sysinternals/cc835722.
In order to install Hyper-V on your Win8 machine you need to access the Programs and Features applet within Control Panel. (Same idea as in Win7). If you are using a mouse-driven version of Win8, hover your mouse in the far bottom left-hand corner and right-click while you see a thumbnail of the Start Page. A new menu will open from which you can select Control Panel. In Control Panel, select Programs.
After you have clicked on “Turn Windows Features On or Off” you will see the following:
Enable Hyper-V by putting a checkmark in the appropriate box. Notice in the above image that “Hyper-V Platform” is greyed out. This is because this host does not have support for the SLAT capabilities discussed above.
In order to manage Hyper-V you can access the Management Console via Administrative Tools, also in Control Panel. Go to “System and Security”
Once in Administrative Tools, you will see a choice to manage Hyper-V:
Open up Hyper-V Manager and you can start building your virtual environment. I recommend right-clicking on the shortcut and choose to pin to your Start Menu, and, if you like, pin to your task bar.
That’s all for today on WIn8 Hyper-V installation.
