For my PhD thesis I wrote a simple tool to measure VM-entry and VM-exit turnaround time - vmlatency. The tool was initially implemented for Linux only. Later ported to macOS. Windows port wan’t finished because I have other activities to deal with prior to the PhD defense. In 2021 I ported the tool on Windows but the port only worked with ICC compiler. The main reason for using ICC was GNU-style inline assembler that was heavily used to execute various processor instructions.
