Creation method of virtual machine, management system of virtual machine and related equipment thereof

Abstract

The invention discloses a creation method of a virtual machine, a management system of the virtual machine and related equipment of the management system. The creation method of the virtual machine, the management system of the virtual machine and related equipment thereof are used for improving performance of the network and an image storage server, and shortening the consumed time to create the virtual machine. The creation method of the virtual machine includes that receiving creation request initiated by a user, confirming a specified type of the virtual machine operating system image requested by the virtual machine creation in an image buffer pool, selecting an objective physical machine to deploy the virtual machine in a hardware resource pool composed of a large number of physical machines according to the creation request of the virtual machine for specified resource requirements, wherein the image buffer pool is built in hardware resources and composed of all physical machines for catching various types of virtual machine operating system images; transferring the specified type of the virtual machine operating system image requested by the virtual machine creation in the image buffer pool to virtual machine running directories of the physical machines; and ordering the physical machine to start the virtual machine.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method for creating a virtual machine, a virtual machine management system and related equipment. Background technique [0002] The IaaS (Infrastructure-as-a-Service) model is a typical service model of cloud computing. It encapsulates computing resources, network resources and storage resources in the data center through virtualization technology and provides them to users in the form of virtual machines. . Users can apply for virtual machine resources on demand through the web (World Wide Web) self-service form. [0003] A typical IaaS virtual machine management system has such figure 1 In the structure shown, a large number of physical machines form a hardware resource pool, and a virtual machine monitor (VMM) runs on each physical machine. The virtual machine monitor is responsible for managing the underlying hardware resources and the upper-level virtual machines. Each vir...

Problems solved by technology

Moreover, the size of the virtual machine operating system image is usually between several G to dozens of G, and a large amount of network bandwidth and storage I / O (input and output) bandwidth will be occupied during the copying process of the virtual machine operating system image.

[0009] Since the virtual machine application is provided to users through web self-service, and the user's demand for virtual machine resources is relatively uncertain, when a large number of users apply for virtual machine resources intensively, on the one hand, it will cause network and image storage server On the other hand, users need to wait for a long time for the replication of the virtual machine operating system image, which seriously affects the user experience
