Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] In order to illustrate the virtual machine memory migration method based on the downtime threshold, a virtual machine and memory migration example as shown in Figure 3 is given here. Currently, there is a virtual machine (virtual machine A) on the source server (59.64.11.100) , the memory (memory A) has 100 pages, and the virtual ma...

Abstract

The present invention relates to a virtual machine internal storage migration method based on down time threshold, consisting of a virtual machine internal storage page transmit module, a virtual machine internal storage dirty page monitoring module, and a virtual machine internal storage migration decision-making module. The method realizes the migration of virtual machine internal storage from an original server to a targeted server through negotiation of page migration transmission speed, calculation of down time threshold and disposition of two core points, and may realize virtual machine on-line migration in a true sense in a retransmission process of a dirty page.

Description

technical field [0001] The invention relates to a virtual machine memory migration method based on a downtime threshold, which is applied to a network operating system based on cloud computing and belongs to the field of computer science and technology. Background technique [0002] At present, cloud computing technology has begun to support search engines and network applications. Cloud computing can not only reduce the cost of informatization, speed up the process of informatization, better serve the society, but also promote the popularization and development of advanced computing and storage applications. Most of the technologies of cloud computing are integrated into the network operating system. [0003] Virtual machine migration is a key technology in cloud computing. Virtual machine migration is to keep the virtual machine running while migrating it from one computer (source computer) to another computer (target computer) and restore the virtual machine on the target...
