Problems solved by technology

However, many early-developed applications and some small enterprise-oriented applications directly use IP addresses to address servers or clients, and their architectures are not designed for virtualized cloud platforms.
When migrating to the cloud platform for virtual machine migration, because the associated virtual machine does not know the IP address mapping relationship before and after the virtual machine migration and still uses the IP address before the migration to address the migrated virtual machine, the application connection will be lost

Embodiment Construction

[0032] The content of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0033] figure 1 is an exemplary block diagram of a virtual machine migration system according to an embodiment, and the system may include, for example, multiple virtualized cloud data center networks 100-101 located in the same geographic location or different geographic locations, for connecting multiple data centers IP network 160, global migration manager 140, external network 150 and clients 170-171.

[0034] Each virtualized cloud data center network 100-101 includes, for example, multiple physical hosts 120-122, a number of virtual machines 200-205 running on the physical hosts 120-122, and gateways (border gateways) 130-131, executing various The virtual machines 200-205 of the application program provide cloud services to external users by connecting to the border gateway of the data center. The following virtualized clou...

Abstract

The invention provides a global migration manager, a gateway, a virtual machine migration system and a method thereof. The business continuity and the cloud service quality are ensured in the migration among different subnets. The global migration manager comprises a memory used for storing a virtual machine information management table of global unique virtual machine identification information; a virtual machine migration controller which is used for receiving a virtual machine migration request and notifying a source subnet to migrate a virtual machine in the source subnet to a target subnet and is further used for receiving a virtual machine migration completion notification, updating the virtual machine information management table and generating a virtual machine destination address transition request according to the global unique virtual machine identification information, a network address of the virtual machine before the migration and a network address of the virtual machine after the migration; and a gateway controller used for sending the generated virtual machine destination address transition request to each gateway and sending a false ARP update request message to the gateway of the source subnet. By adopting the technical scheme, the business continuity and the cloud service quality are ensured.

Description

technical field [0001] The invention relates to a global migration manager, a gateway, a virtual machine migration system, a control method using the global migration manager, a gateway control method and a virtual machine migration method of the virtual machine migration system. Background technique [0002] With the rapid development of computer hardware performance, virtualization technology is being widely used in all levels of data centers based on cloud computing, such as network virtualization, storage virtualization and server virtualization. Server virtualization uses a virtualization management program (or virtualization software) to virtualize a physical host into multiple virtual machines, each virtual machine is independent of each other, and shares various hardware resources on the host, including CPU, storage, network, etc. . Server virtualization can not only improve the resource utilization efficiency of the entire data center IT environment, but also manag...
