Problems solved by technology

[0006] However, the above configuration has changed a lot to the virtual machine itself.
On the other hand, all the user data is stored in the virtual machine, and entering the virtual machine for configuration will affect the privacy of the user and bring unsafe factors to the user

Abstract

The invention discloses a load balancing method, server and system for a virtual machine cluster. The method is applied to a server where at least one virtual machine is established and comprises the steps that an agency unit which is arranged between a virtual network interface card of the virtual machine and a physical network interface card of the server in the server intercepts ARP requests sent by a client, the agency unit can configure a virtual IP address identical with the IP address of a load balancer for each virtual machine, the virtual machine chosen by the load balancer can receive second request message sent by the load balancer, the chosen virtual machine can generate response message according to the second request message, a source address of the response message is the virtual IP address, and the agency unit can send the response message to the client. By means of the load balancing method, load balance can be achieved without carrying out configuration in the virtual machine, and the safety of the system is improved.

Description

technical field [0001] The invention relates to the field of virtual machine clusters, in particular to a load balancing method, server and system for virtual machine clusters. Background technique [0002] With the development of computer technology, especially the development and utilization of network technology, people have put forward higher requirements for computer systems, especially network servers. It is becoming more and more difficult to improve server performance simply by improving the processing power of a single processor. It's getting harder and harder. Therefore, computer cluster services are widely used. A computer cluster, referred to as a cluster for short, is a computer system that is connected through a group of loosely integrated computer software or hardware to work closely together to complete computing tasks. When the cluster works through one or more virtual machines simulated on the server, the computer cluster is a virtual machine cluster. ...
