Q & A: How can I tell if my processor has virtualization and SLAT Support?

Use coreinfo to determine your CPU's virtualization capabilties

Q: I have a few older unused servers that I’d like to use to test Windows Server 2016 and Hyper-V. However, I’ve understood that Hyper-V in Windows Server 2016 requires that the processor supports Second Level Address Translation (SLAT). How can I tell if the processors in these older systems have virtualization and SLAT support?

A: The Sysinternals coreinfo utilty can report on the virtualization support that’s present in your systems. To get a quick report of just the virtualization support you can run coreinfo using the –v switch like you can see in Figure 1.

Figure 1 – Running coreinfo.exe

For an Intel-based system the value of the EPT prompt indicates whether the system supports SLAT. If the value of EPT has an asterisk then SLAT is supported. If the value is a dash like you see in Figure 1 then SLAT is not supported.  You can download coreinfo.exe from Windows Sysinternals Coreinfo v3.31.
