Abstract

The invention discloses an active memory prediction migration method in a virtual machine migration process and belongs to the technical field of virtual machine migration. The method comprises the following steps of: firstly, preprocessing a pre-recorded page set consisting of an address of an accessed memory and accessed time recorded by a virtual machine manager by adopting a method of expressing each memory page by using a six-tuple; and then calculating a priority weight of the memory page, and performing clustering analysis by adopting an ISS-DBSCAN clustering algorithm to determine an active memory range; and finally, adjusting the sending sequence of the active memory pages by taking the priority weight of the memory pages as a judgment basis of the priority. According to the method, a theoretical basis and a method are provided for active memory analysis, the activity degree of the memory page can be effectively predicted, and the memory migration efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of virtual machine migration, in particular to a method for predicting and migrating active memory during virtual machine migration. Background technique

[0002] With the generation of big data, the world today has entered an era of data explosion. Despite the rapid development of computer hardware performance, computing power is still the bottleneck of applications. Cloud computing forms a high-performance, high-utilization, and high-reliability computing cluster by providing a configurable shared pool of computing resources. The scale is dynamically scalable, which brings infinite possibilities to computing and can meet the growing number of users. scale and mission requirements. In order to achieve this unlimited computing capacity, the cloud computing platform needs to provide different users with a completely isolated operating environment, and also dynamically allocate massive computing resources and...
