Naturally, if you turn off the physical server, the illusion will disappear – the hypervisor will stop working. However, each of these virtual machines is simply a set of files in the host’s memory. This way, one computer appears to be multiple computers at the same time, and each works with its own software independent of the others. This illusion is created using hypervisors.Ī schematic representation of a virtual machine In other words, virtualization is the illusion that multiple separate computers, or virtual machines, are present on the same physical equipment. The physical resources are distributed using a hypervisor to create a number of independent virtual machines. This physical machine is referred to as a host it has its own CPU, RAM and storage configuration. Virtualization is a technology which creates the appearance of multiple computers or servers based on one physical computer, server or server cluster. This connection can be used for shared access to certain files or exchanging data through the local network. If needed, a hypervisor can allow the operating systems of separate virtual machines to interact. Users can install guest operating systems on each of the virtual machines with no ties to the host hardware.Ī hypervisor isolates the operating systems from each other so that each one gets exclusive use of the resources dedicated to it. Each clone is presented to the user as a separate device. In other words, a hypervisor creates copies or clones of one physical computer’s hardware resources. Virtualization systems & hypervisorsĪ hypervisor is a program which controls the physical resources of a computing machine and distributes those resources between a number of various operating systems, which allows them to be run at the same time. What is a hypervisor and what is it used for? In this article, we will explain the basics of virtualization, describe the types of this technology and look into the most popular specific solutions. ![]()
