Method, device and system for link management in virtual machine environment

Abstract

The present invention provides a link management method, device and system in a virtual machine environment; the method includes: establishing a heartbeat handshake link with the virtual machine; after the heartbeat handshake link is successfully constructed, obtaining the physical Link aggregation control protocol LACP state information of the port; sending the LACP state information to the virtual machine through the heartbeat handshake link.

Description

technical field [0001] The present invention relates to the communication field, in particular to a link management method, device and system in a virtual machine environment. Background technique [0002] In traditional IT network equipment, in order to reduce the complexity of server network interface management, and at the same time, application software has an increasing demand for network interface bandwidth, Link Aggregation Control Protocol (LACP, Link Aggregation Control Protocol) is generally used for multiple external network interfaces of servers. ), aggregate multiple physical ports into one aggregation port for use by OS and upper-layer services. [0003] In a non-virtualized host operating system (Operation System, OS), by running the 802.3ad link aggregation control protocol, the negotiation and management of multiple ports connected to the switch side can be automatically completed. In the virtual machine environment, the network card device realizes multipl...

AI Technical Summary

Problems solved by technology

[0009] It can be seen from the above that the above two methods have the problem that the full path detection of the virtual machine network link cannot be realized, resulting in the occurrence of packet loss in the LACP aggregation group of the virtual machine when the internal port of the VF is abnormal.
