Method and Apparatus for Migrating Virtual Machine Parameters and Virtual Machine Server

A method for migrating virtual machine parameters, comprising:

• sending a virtual machine parameter migration message at a not-running stage of a virtual machine, wherein 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 comprises an identifier of the virtual machine.

A migration management apparatus, comprising a receiving unit and a migrating unit, wherein:

• the receiving unit is configured to receive a virtual machine parameter migration message at a not-running stage of a virtual machine, wherein 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 comprises an identifier of the virtual machine;
• and
• the migrating unit is configured to migrate virtual machine parameters according to the virtual machine parameter migration message.

A network device, wherein the network device is located on an upstream path of a virtual machine, and the network device comprises a receiving unit and a migrating unit, wherein:

• the receiving unit is configured to receive a virtual machine parameter migration message at a not-running stage of the virtual machine, wherein the virtual machine parameter migration message comprises an identifier of the virtual machine and a virtual machine parameter migration indication, wherein the virtual machine parameter migration indication is used to instruct an upstream network device of the virtual machine to migrate virtual machine parameters at the not-running stage of the virtual machine and used to indicate a migration state of the virtual machine, wherein the migration state comprises in-migration and out-migration;
• and
• the migrating unit is configured to migrate virtual machine parameters according to the virtual machine parameter migration message.

A virtual machine server, comprising a triggering unit and a sending unit, wherein:

• the triggering unit is configured to trigger, at a not-running stage of a virtual machine, the sending unit to send a virtual machine parameter migration message;
• and
• the sending unit is configured to send the virtual machine parameter migration message, wherein 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 comprises an identifier of the virtual machine.
