Virtualisation of hardware

Hello guys,

I want to ask for some interresting things before I can start doing what I want. What about: I want to setup my roommate's PC to Ubuntu Server in the way I can access to it from my laptop (a.k.a I want to virtualised his PC).

I'm not asking for steps like "how I can do that, please help", no no no, I can use google :)

His PC has installed Windows 10 on HDD. Also has Intel i5 / 16 GB of RAM etc. I want to add my personal HDD to his PC and on this HDD (separate from his one) want to install server and virtualised hardware.

My question: If I do this and all hardware tranform to VM so I can work on it and then I close the session / VM and reboot PC back to Win10, will be the hardware de-virtualised or stay in some king of virtualised-form and will not be used in other way (also in way, that I fully shut the server and the server will not longer use these components).

Thanks for your opinnion :)

Also I'm sorry if someone create same thread and this is just a copy...

Cheers,
Michal
