nohv is a kernel driver for detecting Intel VT-x hypervisors. It is useful for benchmarking your hypervisor against common vm-detections.

To clone the repo:

git clone --recursive https://github.com/jonomango/nohv.git

nohv is a Windows driver built with MSVC. It requires Visual Studio and the WDK for compilation.

Once compiled, nohv.sys must be loaded with SEH support. This means that you can't manual map the driver (unless you're a wizard) since it'll crash the moment an exception is thrown. I recommend restarting Windows while holding SHIFT and disabling Driver Signature Enforcement, then load the driver normally (OSR Loader if you're lazy) and hope you don't BSOD 😃.

This is a fairly old project of mine and it's missing a lot of common detections (such as NMI checks). Also this WILL bluescreen you if your hypervisor sucks. Make sure to test this BEFORE loading your hypervisor, as well as after.
