One of the new features in Windows 8 is Hyper-V. This technology was originally included in Server 2008 and now included in the desktop OS. It let’s you setup, manage and run virtual machines on your Windows 8 box. Hyper-V virtualization technology has certain hardware requirements though and only works on newer computer processors. Here’s how you can test your CPU to see if it will support Windows 8 Hyper-V.
Windows 8 Hyper-V
First, you need an AMD or Intel 64-bit processor that supports Second Level Address Translation (SLAT). SLAT virtualization hardware is included in most modern Intel Core i3, i5 and i7 CPUs. It’s also included in AMD’s Barcelona processor line. Even if your CPU supports virtualization (XP Mode in Windows 7 for example), it might not have SLAT hardware virtualization technology. If you have an Intel Core 2 CPU in your system for example, it doesn’t support the SLAT feature so you won’t be able to add the Hyper-V feature.
In addition to the CPU requirements, your system will also need a minimum of 4GB of RAM and the 64-bit version of Windows 8.
It’s a bit confusing I know. And how do you know if your CPU supports SLAT anyway? Here’s a couple of utilities that will help you determine in your system supports SLAT technology so you can utilize the Hyper-V technology in Windows 8.
Test System CPU for SLAT Using CoreInfo
There are a couple of free utilities that will test your CPU for SLAT capability. Created by Microsoft wiz Mark Russinovich, CoreInfo is a command line utility that will work on both AMD and Intel systems.
Download the zip package and extract coreinfo.exe to your C:\ drive.
Next go to Start >> All programs >> Accessories and right-click on Command Prompt and select Run as Administrator.
Now, in the command line type: cd c:\ when the C: prompt comes up type: coreinfo.exe –v
If you see an asterisk next to EPT (Extended Page Tables), your CPU is groovy and you’re good to go.Your system supports Widows 8 Hyper-V.
If you run CoreInfo on an AMD system – using the same commands as above, look for an asterisk on the NP (Nested Page Tables) line. On my AMD system, I have an AMD Athlon Dual Core CPU and it doesn’t support SLAT.
So again, your looking for an *, not a -. Here’s another Intel Processor which shows it doesn’t support SLAT technology. No Hyper-V for you!
