I got this question during an online interview.

This key question is from Hypervisors in chapter Abstraction and Virtualization Layer and Capacity Planning of Cloud Computing

Answer 1

Correct answer is (a) Full virtualization requires that the host operating system provide a virtual machine interface for the guest operating system and that the guest access hardware through that host VM

Easiest explanation: An operating system running as a guest on a paravirtualization system must be ported to work with the host interface.
