Abstract
A method for migrating configuration information during live migration of a virtual machine is disclosed. The method includes, after receiving a message of live migration that a virtual machine migrates from a source physical host to a target physical host sent by a virtual machine management server, acquiring an identifier of a source forwarding switch of the virtual machine and an identifier of a target forwarding switch of the virtual machine, and sending prestored configuration information to the target forwarding switch corresponding to the identifier of the target forwarding switch, so that the target forwarding switch stores the configuration information. The method also includes sending a configuration information deletion instruction to the source forwarding switch corresponding to the identifier of the source forwarding switch, so that the source forwarding switch deletes the prestored configuration information.
