Abstract

The invention provides a method for dynamic migration of WAN (Wide Area Network) virtual machines. The method aims to perform dynamic migration of one or more virtual machines from a source host to a destination host in a wide area network. The method comprises the following steps of: establishing a distributed index of the internal memory and external memory data of all virtual machines in operation in a data center to which the destination host belongs, thus forming a destination host environment; in the migration process of the virtual machines, retrieving the internal memory and external memory data of the virtual machines in the source host in the destination host environment, and transmitting the internal memory and external memory data not present in the destination host environment only through the wide area network; and simultaneously, in the transmission process, marking internal memory and external memory dirty blocks by the virtual machine manager of the source host, iteratively sending the internal memory and external memory dirty blocks until reaching a stop condition, and then stopping the transmission of the internal memory and external memory, causing the virtual machines in the source host to enter a stop stage, and starting the virtual machines by the destination host. The method is capable of reducing the network bandwidth occupied by the migration of the virtual machines in the wide area network and shortening the time of the dynamic migration of the virtual machines.

Description

technical field [0001] The invention belongs to the field of virtual machine migration, in particular to a fast and dynamic migration method and system for virtual machine memory and external storage data on a wide area network. Background technique [0002] Virtualization means that the computing elements run on the virtual infrastructure instead of the real infrastructure. Virtualization technology is used to integrate distributed physical computer resources, and to manage processing power, storage and network infrastructure in a unified manner. These computer resources are provided in the form of services and allocated to different virtual machines. Through the integrated management of resources, IT complexity is reduced, resource utilization is improved, computer room space is saved, costs are reduced, system availability is reduced, and System interruption time ensures data security and business continuity. [0003] After the virtual machine manager (Virtual Machine Mo...
