Method and device for upgrading virtual switch

Abstract

The invention provides a method and a device for upgrading a virtual switch. The method is applied to main control equipment, the main control equipment forms a cluster with at least one other control equipment, all the control equipment in the cluster are respectively connected with at least two servers, an OVS (Open Virtual Switch) is mounted on each server, and each OVS is connected with at least one virtual machine. The method comprises the following steps: configuring a port made for the migration of the virtual machine based on the second OVS and updating stored virtual machine information; thermally migrating the virtual machine to the lower part of the second OVS based on the updated virtual machine information; configuring a port made for the emigration of the virtual machine based on the first OVS and adding an identifier to corresponding information in the virtual machine information; upgrading the first OVS based on the identified information; after the completion of upgrading, migrating back the virtual machine from the second OVS to the upgraded first OVS based on the identified information. According to the method and the device provided by the invention, the virtual machine can be guaranteed not to be off line and cut off in the OVS upgrading process and not to influence the user experience.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to a method and device for upgrading a virtual switch. Background technique

[0002] OVS (Open Virtual Switch, Open Virtual Switch) is a virtual switch that can support multiple standard management interfaces and protocols, and can support a distributed environment of multiple physical servers.

[0003] When the OVS on the server needs to be upgraded, all online virtual machines under the server need to be offline before the upgrade, and all OVS port information on the server needs to be deleted, and then the control component controls the server to perform the OVS version Updates and upgrades.

[0004] It can be seen that in the prior art, all virtual machine services under the server where the OVS is located are all interrupted during the upgrade process of the OVS, and the virtual machine of the entire network is offline and interrupted, which will greatly reduce t...
