Abstract

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.
