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

Disclosed are a virtual machine migration method and device. In the present invention, the method comprises: marking a memory page in a memory of a source virtual machine, in which data to be migrated is stored, as a dirty page; within a set time, migrating the data to be migrated, which is stored in the memory page marked as the dirty page, to a target virtual machine; if the migration time reaches the set time, determining a migration policy, the migration policy being used for migrating the data to be migrated, which is stored in the memory page marked as the dirty page and is not migrated; and in accordance with the migration policy, migrating the data to be migrated, which is stored in the memory page marked as the dirty page and is not migrated, to the target virtual machine. The virtual machine migration method provided in the present invention can be adapted to a network environment 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 the virtual machine (Virtual Machine, VM) online migration (online migration) technology is a hot spot in the virtualization technology. [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...
