Service method and system based on virtual machine one-button packaging migration

Abstract

The invention provides a service method and system based on virtual machine one-button packaging migration. The memory transfer method includes the steps that in a source host mainframe, a client mainframe memory is locked, and information in the client mainframe memory is transferred to a target host mainframe; in the transfer process, a new memory partition is opened in the source host mainframe to provide services for a client mainframe, wherein the new memory partition only stores changed content of the client mainframe memory; the new memory partition is locked, and the information in the new memory partition is transferred to the target host mainframe. According to the service method and system, no data or service on a virtual machine is influenced, and services will not be interrupted in the migration process; service interruption generated in a traditional mode can be avoided, and the service method and system are suitable for scenarios with high service availability requirements.

Description

technical field [0001] The present invention relates to the field of virtualization-based cloud computing services, in particular to a virtual machine-based one-click packing and moving service method and system. Background technique [0002] In order to improve the overall availability, security and continuity of the IT system, the high availability requirements of business applications are getting higher and higher. All applications running in virtual machines provide easy-to-use, cost-effective high availability. [0003] While ensuring the normal operation of the services on the virtual machine, the virtual machine is migrated between different physical hosts. The logical steps are similar to the traditional offline migration. There is only a very short millisecond-level downtime in the process, and users do not feel the interruption of services. In the previous stage of the move, the service runs on the source host. When the move reaches a certain stage, the destinatio...

AI Technical Summary

Problems solved by technology

[0005] 1) When the original computing server fails in the existing service application, the failure will lead to business interruption and affect business use

[0006] 2) When migrating a virtual machine in the traditional way, the virtual machine needs to be suspended for a period of time, and the business needs to be interrupted

[0007] 3) If the migrated node has insufficient resources, there may be a risk of migration failure
