Abstract

An embodiment of the invention provides a method for virtual machine migration in a network. The method comprises: before a virtual machine migrating from a second entity gateway to a first entity gateway, the first entity gateway configuring a virtual gateway IP address; after the virtual machine migrating from a second entity gateway to a first entity gateway, the first entity gateway receiving a free address resolution protocol (ARP) message sent by the virtual machine, the free ARP message comprising an IP address of the virtual machine and an MAC address; the first entity gateway generating routing of the virtual machine according to the IP address of the virtual machine; and the first entity gateway issuing the routing of the virtual machine to a data center. The embodiment of the invention also provides an entity gateway and a system for virtual machine migration. Through the technical scheme provided in the embodiment, when the virtual machine migrates, default gateway configured in the virtual machine does not need reconfiguration. The virtual machine cannot aware changes of the gateway, so that a problem of flow interruption in a process of the virtual machine migration caused by gateway changing is prevented.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, gateway and system for virtual machine migration in a network. Background technique [0002] A virtual machine (English full name is Virtual Machine, English abbreviation VM) is a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Wherein, in some cases, a virtual machine migration (migration) technology needs to be applied. Virtual machine migration technology utilizes full virtualization of servers, storage and network connections to instantly move an entire running virtual machine from one server to another. [0003] An important requirement for virtual machine migration is to avoid service interruption. After virtual machine migration in a three-tier network, the Internet Protocol (Internet Protocol, English abbreviated as IP) address o...
