Abstract

The present invention discloses a method and device for smooth switching of a virtual machine entity live migration network, including: the virtual machine entity hot migration from the source physical server to the target physical server enters the final stage, and before the virtual machine entity is shut down, start the network migration assistance The program caches the datagram sent to the virtual machine entity on the source physical server; after obtaining the power-on status information of the virtual machine entity on the target physical server, forwards the cached datagram to the virtual machine entity on the target physical server. The method and device for smooth switching of virtual machine entity hot migration network provided in the present invention overcome the problem of data packet loss during hot migration, and can be applied to any form of Ethernet network.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and device for smooth switching of a virtual machine entity hot migration network. Background technique [0002] VM (virtual machine) and container (container) are commonly used virtualization technologies, and live migration technology has been developed on them. In this article, the virtual machine entity is used to refer to both virtual machines and containers. [0003] Virtual machine entity hot migration is to migrate a serving virtual machine entity from one physical server to a new physical server. [0004] The hot migration technology of the virtual machine entity refers to the migration of the virtual machine entity between different physical servers while ensuring the normal operation of the service on the virtual machine entity. The advantage of live migration is to simplify system maintenance and management, improve system load balance, enhance sys...
