When you issue a “systeminfo” check out the System Manufacturer and System Model J



System Manufacturer: VMware, Inc.

System Model: VMware Virtual Platform



System Manufacturer: Microsoft Corporation

System Model: Virtual Machine



Works fine on Hyper-V and ESX.

I would avoid using integration tools as the check. I would use WMI. There are several reliable ways via WMI (ignoring malicious intent.)

You could as well query for the presence of Hyper-V integration services or VMware tools. However, this depends on those services being present in the first place.

Apart from these "soft" criteria there is no way for a machine to reliably find out if it's running on iron or not as the CPU virtualization features do not support such a distinction. This is what Rutkowska's "Blue Pill" uses for its attack.

Hi All,



Is there any way to find out server is running on Virtual/ physical mode by checking any services or anywhere? other than naming conventions we use...
