What is the primary role of a hypervisor in a virtual

Solution

A hypervisor, also known as a Virtual Machine Monitor (VMM), is a software layer that creates and manages virtual machines on a host system. It allows multiple virtual machines (VMs) to run on a single physical machine by sharing hardware resources like CPU, memory, and storage. There are two types of hypervisors: Type 1, which runs directly on the hardware (bare-metal), and Type 2, which runs on top of an operating system. The hypervisor ensures that each VM operates independently while allocating and managing system resources. Option A (Manage hardware clock cycles) is incorrect because the hypervisor manages resource allocation but does not specifically manage hardware clock cycles, which is the responsibility of the processor. Option B (Act as the operating system for virtual machines) is incorrect because the hypervisor is not an operating system; it is a layer that allows VMs to run their own independent operating systems. Option C (Allocate storage resources between physical machines) is incorrect because the hypervisor primarily manages resource allocation for virtual machines on a single physical machine, not between multiple physical machines. Option D (Provide network connectivity for VMs) is incorrect because while a hypervisor may manage network resources for VMs, its primary role is creating and managing the VMs themselves.
