Question

Which interface simulates hardware and occurs in such a way that a system itself can run unmodified on top of the hypervisors?

Answer 1

Since the options are not given, I am giving a general assumed answer.

The correct answer could be - Guest system interface.

In hardware virtualization, Guest systems are interfaces that simulate the hardware and they occur in a way that the guest system can run independently by itself in an unmodified state on top of the hypervisor.

A guest operating system using emulation does not need to be modified in any way.
