Method, migration management apparatus, network device, and virtual machine server for migrating virtual machine parameters

摘要

The present invention provides a method and an apparatus for migrating virtual machine parameters and a virtual machine server. The method includes receiving a virtual machine parameter migration message at a not-running stage of a virtual machine, where the virtual machine parameter migration message is used to cause an upstream network device of the virtual machine to migrate virtual machine parameters of the virtual machine at the not-running stage of the virtual machine, and the virtual machine parameter migration message includes an identifier of the virtual machine. The present invention may implement migration of the virtual machine parameters correctly and solve a service interruption problem in virtual machine migration.

1. A method for migrating virtual machine parameters, comprising:
receiving a virtual machine parameter migration message sent by a first server at an out-migration location of a virtual machine, at a not-running stage of the virtual machine; and migrating virtual machine parameters according to the virtual machine parameter migration message by causing an upstream network device corresponding to the out-migration location of the virtual machine to migrate the virtual machine parameters of the virtual machine at the not-running stage of the virtual machine, so that the virtual machine parameters of the virtual machine stored in the upstream network device corresponding to the out-migration location of the virtual machine are migrated to an upstream network device corresponding to an in-migration location of the virtual machine; wherein the virtual machine parameter migration message comprises an identifier of the virtual machine; wherein the virtual machine parameters are dynamic information stored in the upstream network device corresponding to the out-migration location of the virtual machine; wherein the upstream network device corresponding to the out-migration location of the virtual machine is a network device that is between the first server from which the virtual machine is migrating and a first gateway; and wherein the upstream network device corresponding to the in-migration location of the virtual machine is a network device that is between a second server to which the virtual machine is migrating and a second gateway.
