Problems solved by technology

ARM processors are widely used in mobile terminals and embedded systems, and the network environment is often relatively complex
However, the current virtual machine online migration technology is widely used on the x86 platform. Compared with the ARM platform, the x86 platform has a relatively simple network environment, so the virtual machine migration technology based on the x86 platform is not suitable for the ARM platform.
[0005] The virtualization research based on the ARM platform is still in a relatively blank stage, and it is imperative to provide a virtual machine migration method suitable for the ARM platform

Abstract

The invention discloses a virtual machine migration method and device; the method comprises the following steps: identifying memory pages with to be migrated data in a source virtual machine memory to be dirty pages; migrating the to be migrated data stored in the memory pages identified as dirty pages to a target virtual machine in a set time period; determining a migration strategy when the migration time reaches the set time period, and the migration strategy is used for migrating non-migrated to be migrated data stored in the memory pages identified as dirty pages in the source virtual machine; migrating the non-migrated to be migrated data stored in the memory pages identified as dirty pages from the source virtual machine to the target virtual machine according to the migration strategy. The virtual machine migration method can adapt to network environments, and is suitable for an ARM platform.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a virtual machine migration method and device. Background technique [0002] With the continuous development of science and technology, virtualization technology, as a key technology applied to servers, has the advantages of integrating heterogeneity, facilitating real-time maintenance and management, saving power consumption and security, etc., and the application of virtualization technology is becoming more and more Widely, and virtual machine (Virtual Machine, VM) online migration (onlinemigration) technology is a hotspot among virtualization technologies. [0003] The virtual machine online migration technology refers to the migration of the virtual machine between different physical hosts while ensuring the normal operation of the services on the virtual machine. In order to ensure the availability of services on the virtual machine, the migration proc...
