Decision method and control module facing to cloud computing virtual machine migration

Abstract

The invention provides a decision method and a control module facing to cloud computing virtual machine migration. The control module is composed of a migration trigger module, a virtual machine choosing module and a destination node choosing module. The method includes: firstly setting load threshold value of the system through the migration trigger module, and enabling the system to effectively prevent instant load peak value from triggering unnecessary virtual machine migration by utilizing the load forecast technology; enabling the virtual machine choosing module to choose the virtual machine needing migration according to the migration cost minimum strategy, and reducing the migration cost of the virtual machine to the minimum value to save system resources; and finally, enabling the destination node choosing module to provide the destination node choosing strategy based on weighting probability choosing algorithm. Therefore, the problem of aggregation collision caused by migration of a large number of virtual machines is effectively solved. At last, the decision method can well achieve load balancing and enables resources to be used fair and reasonably.

Description

technical field [0001] The invention relates to a decision-making method and a control module for cloud computing virtual machine migration. The method is applied to virtual machine migration in a cloud computing network system and belongs to the field of computer science and technology. Background technique [0002] Cloud computing (cloud computing) is a technology direction that has risen internationally in recent years, and it is also a research hotspot in the field of information technology. Cloud computing is a new computing method based on the Internet. In this way, the hardware resources of the entire system are virtualized into a unified virtual resource pool, and then all resources in the system are allocated to users according to actual needs or other policies with the help of a virtualization management platform. Because cloud computing realizes the unified management of computer resources, users no longer participate in the construction, management and maintenan...

Problems solved by technology

[0005] The existing migration mechanism generally manages the entire migration process through the virtual machine controller, and mainly uses the host CPU utilization as the basis for the node to start the migration, and the selection strategy of the migration destination node is usually based on random selection or based on the minimum bandwidth occupation, resulting in Existing migration strategies generally lack comprehensiveness in system resource sensitivity and resource analysis

In addition, the use of existing migration strategies for virtual machine migration can easily lead to unnecessary virtual machine migration triggered by instantaneous load peaks, or cause migration service conflicts caused by clustering effects, and even trigger secondary migration due to unreasonable selection of migration destination nodes

In view of the fact that the migration of virtual machines in the cloud computing system has the characteristics of large amount of migration data transmission and long time consumption, this patent proposes a decision-making method and control module for cloud computing virtual machine migration, which includes a migration trigger module, a virtual host selection module and Destination node selection module
