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.gitnohv 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.
