Method for realizing platform migration by using virtualization technology

Abstract

The invention discloses a method for realizing platform migration by using virtualization technology. The method comprises the following steps of: building a virtualization platform on a source server, configuring a source memory device and establishing mapping relationship between the original memory device and the source server to form a source virtualization platform; determining whether the migration is online migration or offline migration, if the migration is the online migration, stopping trunking services and normally operating application on a single source virtual machine so as to ensure the non-interruption of the services; deploying virtualization backup software on a backup server to form a virtualization backup tool; backing up a mapping file of the source virtual machine by using the virtualization backup tool; building, deploying and storing a target virtualization platform; recovering the mapping file to the target virtualization platform; and starting the application on the target virtualization platform and stopping the application on the source virtualization platform at the same time so as to realize the cross-hardware platform online migration of the application. In the method, as the online backup function of the virtualization backup tool is utilized, so that all the services operated in a trunking environment are not interrupted.

Description

technical field [0001] The present invention relates to a method for implementing platform migration by using virtualization technology, specifically a method for migrating applications on different hardware platforms, and a method for implementing online migration of a virtualization platform that has deployed a cluster environment by using a virtualization backup function Methods. Background technique [0002] With the rapid development of virtualization technology, more and more enterprises have deployed virtualized applications in the production environment. Virtualization technology improves resource utilization through the integration of servers, and the many-to-one integration method makes enterprises pose higher challenges to application security. Therefore, many enterprises will deploy traditional cluster software (such as Microsoft MSCS) to protect critical enterprise applications. The development speed of hardware technology is increasing geometrically. The new ...

To achieve the above conditions, the current traditional backup method cannot achieve cross-hardware platform migration. The reasons are as follows: 1. Through backup software: traditional backup software installs a backup agent on the virtual machine, and then backs up the data in the virtual machine through the agent , but the entire system image cannot be backed up, and platform migration cannot be realized by only backing up data to a new hardware platform; second, through virtualization migration tools: the premise of using virtualization migration tools is that the target server and the source server must be shared Storage, and the new hardware platform uses new storage devices, which cannot be realized through virtualization migration tools
