The use of hardware and hardware resources, including memory, processor, disk, network card, and more. In a computer system, we call virtualization more than one operating system for launching and using (hosted) more than one operating system. By definition, systems with two or more boot options and when booting a selected operating system and controlling hardware are not in the virtualization area.

Virtualization is generally done in two ways: The Type1 Type One and its professional term also referred to as the baremetal hypervisor:

Includes the use of a virtualization operating system on the host server and the acquisition of the main resources, such as RAM, processor and disk in the host system, and the assignment and management of resources between the operating systems that are installed as guest (Guest). This type of virtualization is called a hypervisor to a host operating system that is responsible for controlling and dividing I / O and server resources between operating systems.

Type2 or Type II laboratory and home applications In this type of virtualization, an application that is very easy to install and use has been installed on our operating system in the next few steps and, like any other application or application, is installed on the operating system, and it is possible to create a virtual machine or other operating system On a laptop and a personal computer. One of the most famous examples of this type is the VMWare Workstation and the Virtual Box.

The Type One virtual machines are divided into two types. Hypervisors that allow sharing resources between guest operating systems, such as OpenVZ And other types of proprietary devices that give each operating system a specified amount of hardware resources, and if another guest is not filled with resources, another guest will not be in trouble. This virtual type is very important for leasing virtual servers VPS-VDS for leased-outs because it is sure that the amount of memory or client-specific one is very specific. Among the pro-variants of this category are vmWare ESXi, Ms HyperV and Cytrix Xen.


Maybe for you that the administrator of a network is an organization or a big company, you have to start a new program on your network, but to do this you need one or more new servers. A company that sells this software to you may ask you to provide a dedicated server, or you may want to ask your servers for fear that the new software will interfere with your previous software. Separate. In such cases, you should not...
