Cross-data-center virtual machine migration method, service control gateway and cross-data-center virtual machine migration

Abstract

Embodiments of the invention provide a cross-data-center virtual machine migration method, a service control gateway and a cross-data-center virtual machine migration. The migration method comprises: a target service control gateway of a target data center receives virtual machine migration information sent by a source service control gateway of a source data center; the target service control gateway configures a response strategy, an internal data channel between an ingress router of the target data center and a target switch, and an external data channel between the target data center and a user on the target switch; the target service control gateway sends configuration success information to the source service control gateway; and the target service control gateway installs an virtual machine to be migrated on the target server and provides service for the user. According to the embodiments of the invention, the strategy of the target switch can be automatically installed, the external data channel from the user to the target data center can be automatically installed, and the internal data channel between the ingress router of the target data center and the target switch can be automatically installed, thereby achieving the automatic virtual machine migration across data centers.

Description

technical field [0001] The invention relates to virtual machine migration technology, and in particular to a method, service control gateway and system for virtual machine migration across data centers. Background technique [0002] As a data integration system, a data center is usually composed of components such as computing systems, storage systems, communication systems, network equipment, environmental control systems, and security systems. It is often used for computing and storage of core business at the company level, or company organization operations Computation and storage of data. With the continuous development of science and technology and the emergence of technologies such as cloud computing / distributed computing, computing power, storage, etc. have also become an information technology service that is provided to customers. These services can be provided to customers by using the network, information technology, security and other capabilities of the data ce...

AI Technical Summary

Problems solved by technology

For example, virtual machine migration software cannot perceive the security policy and / or QoS policy configured for the virtual machine on the hardware switch, so it cannot configure the security policy and / or QoS policy for the switch corresponding to the target physical server during the migration process; and For example, the virtual machine migration software is not aware of the network conditions inside the data center, and cannot automatically configure the network inside the target data center

All these configuration tasks need to be done manually. When a large number of virtual machines need to be migrated, the configuration volume is huge and error-prone
