It abstracts various physical resources \(such as processors, memory, disks, and network adapters\) of a computer, converts the resources, and presents the resources for segmentation and combination into one or more computer configuration environments. This resource management technology breaks the inseparable barrier of the physical structure, and makes these resources not restricted by the architecture, geographical or physical configuration of the existing resources after virtualization. In this way, users can better leverage the computer hardware resources and maximize the resource utilization. +In computer technology, virtualization is a resource management technology. It abstracts and transforms various physical resources (processors, memory, disks, and network adapters) of a computer, and can be divided and combined into one or more computer configuration environments. This resource management technology breaks the inseparable barrier of the physical structure, and makes these resources not restricted by the architecture, geographical or physical configuration of the existing resources after virtualization. In this way, users can better leverage the computer hardware resources and maximize the resource utilization. Virtualization enables multiple virtual machines \(VMs\) to run on a physical server. The VMs share the processor, memory, and I/O device resources of the physical server, but are logically isolated from each other. In the virtualization technology, the physical server is called a host machine, the VM running on the host machine is called a guest, and the operating system \(OS\) running on the VM is called a guest OS. A layer of software, called the virtualization layer, exists between a host machine and a VM to simulate virtual hardware. This virtualization layer is called a VM monitor, as shown in the following figure.
