I've made some research here and there about virtualization of Linux. I will put quite large chunk text beneath, please correct me when wrong:
Using Linux Full Virtualization distribution like this one, I can use .iso images of both Linux and Windows to start running both machines at exactly same time independantly from one another and without having Linux to be able to see Windows and Windows being able to see Linux. As if they were physical computers. This solution is much more efficient qua CPU, RAM, storage and GPU when compared to Windows and Linux virtualized in let's say VirtualBox or VMware Player/Workstation within working Linux OS, let's say Ubuntu.
This is how I understood it, please correct me when wrong.
