virtualbox – VMWare suspension stages

I have VMWare Workstation Pro 15.x installed on Windows 10 Pro x64.
The guest operating system is Ubuntu 20.04.1 x64.

I was wondering and looking for literature/docs regarding the stages of suspension. Basically, when I hit suspend, what are the stages that take place in the Host OS(such as .vmss creation) and within the Guest OS.

I can’t find some in-depth information about these stages, only some basic stuff such as .vmss creation.

So my question is regarding information, anything would help, but books/papers/docs/tutorial with some in-depth explanation of these stages is really what I’m looking for.
