Introduction
Before knowing about the virtualization management with the hypervisor, we must understand what virtualization and hypervisor are?
Virtualization
Virtualization is a process that allows you to construct useful IT services using resources that are traditionally bound to hardware. It lets you take maximum advantage of a physical machine's capabilities by distributing them among several users or environments.
Hypervisor
A hypervisor is a kind of virtualization software that divides and allocates resources across many pieces of hardware in Cloud hosting. A hypervisor allows multiple guest operating systems (OS) to run simultaneously on a single host machine. A virtual machine manager (VMM) is another name for a hypervisor (VMM).
Managing Virtualization with Hypervisor
We don't want to bother about the underlying operating system or physical hardware in an ideal world. A hypervisor is a technology that ensures resource sharing is done consistently and orderly. It allows multiple guest operating systems (OS) to run simultaneously on a single host machine. The hypervisor sits at the lowest level of the hardware environment and utilizes a thin layer of code (commonly referred to as a fabric) to enable dynamic resource sharing. The hypervisor gives the impression that each operating system has its own set of physical resources.
We may be required to handle a variety of operating environments in the area of big data. For the technical components of the big data stack, the hypervisor becomes an ideal delivery mechanism.
- The hypervisor allows you to run the same program on several platforms without copying it to each system.
- The hypervisor architecture also allows it to load many different operating systems as though they were just another application.
- As a result, the hypervisor is a highly useful tool for quickly and effectively virtualizing objects.
We must understand the hypervisor's nature. It's more like a server OS than a Windows OS. A guest machine is a virtual machine that runs on top of a physical machine. As a result, the hypervisor schedules guest operating systems' access to all resources, including the CPU, RAM, disc I/O, and other I/O mechanisms. The operating systems that operate on the virtual machines are referred to as guest operating systems. We can use virtualization technology to set up a hypervisor that divides the physical computer's resources. For example, resources can be distributed 50/50 or 80/20 between two guest operating systems.
The benefit of this setup is that the hypervisor does all the heavy lifting. The guest operating system is completely unaware that it is running in a virtual partition; it believes it has its own computer.
