Abstract

The present invention provides a virtual machine migration method and device. The method is applied to a mapping server in a LISP network, including: after the virtual machine migrates from the first data center in the LISP network to the second data center in the LISP network, receiving the second data center The registration address of the virtual machine sent by the router of the second data center; a migration notice corresponding to the virtual machine is generated according to the registration address of the virtual machine, and the migration notice is used to instruct the virtual machine to migrate from the first data center to the second data center; The notification is sent to all remote servers in the LISP network, so that the remote server updates the routing information corresponding to the locally saved virtual machine according to the migration notification, and uses the updated routing information to send data packets to the virtual machine. By applying the embodiment of the present invention, during the virtual machine migration process, the flow between the remote server and the migrated virtual machine can be restored as soon as possible, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a virtual machine migration method and device. Background technique [0002] With the development of network communication technology, virtual machine migration technology has also been widely used. [0003] In the prior art, after a virtual machine (Virtual Machine, VM) migrates from a first data center in a Locator Identifier Separation Protocol (LISP) network to a second data center, and the remote server learns that the virtual machine has migrated Before entering the routing information of the second data center, when the remote server sends a data packet to the virtual machine that has migrated out of the first data center, the router of the first data center will The data packets corresponding to the virtual machine are discarded, so that during the virtual machine migration process, the traffic between the remote server and the virtual machine will be tempo...
