Problems solved by technology

[0004] However, according to the experiment of the compression algorithm, it can be known that for some data such as h.264 movies and mp3 files, the compression consumes a lot of CPU resources but the compression effect is not obvious. Therefore, it has a certain impact on the hot migration efficiency of the virtual machine.

Abstract

The invention provides a virtual machine thermal migration memory processing method, device and system. The method comprises the following steps: compression processing of a current to-be-transmitted first memory page block of a virtual machine on a source physical machine is performed by using the first compression algorithm, and storing compression information of the first memory page block; if N memory page blocks containing the first memory page block do not meet preset compression performance after being subjected to compression processing through judging according to the compression information of the first memory page block and compression information of (N-1) memory page blocks transmitted before the first memory page block, and then M memory page blocks after the first memory page block are not subjected to compression processing and are directly transmitted to a target physical machine, wherein the N is greater than 1 and the M is greater than 1. According to the method, the device and the system provided by the invention, the thermal migration performance of the virtual machine is improved, the CPU (Central Processing Unit) overhead of the source physical machine is reduced and processing resources are saved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for processing virtual machine hot migration memory. Background technique [0002] Virtual machine live migration is a key technology in the field of virtualization and an important means to realize dynamic load balancing in the cluster and replace and maintain hosts without interrupting business conditions. The basic principle of virtual machine live migration is to migrate the running virtual machine from the source physical machine to the target physical machine without affecting the user's business or the user's perception, and reducing the migration time and resource consumption is to improve the efficiency of live migration means. [0003] Since the memory data volume of the virtual machine is much larger than other information of the virtual machine, optimizing the memory page transfer method of the virtu...
