Embodiment approach

[0048] VMM22 is used for: sampling and obtaining the data packets of the virtual machine 23 in the virtual machine list, according to the IP information and the corresponding quantity of the data packets, counting the inflow source IP address and the corresponding flow data of the corresponding virtual machine 23, the outflow target IP address and the corresponding traffic data, and output the corresponding statistical results to the network traffic monitoring module 24, and after receiving the virtual machine migration command issued by the virtual machine deployment adjustment module 11, migrate the virtual machine 23 to be migrated to the corresponding virtual machine migration command according to the virtual machine migration command on the target service node 2;

[0049] The network traffic monitoring module 24 is specifically used to: count the virtual machine list exceeding the traffic threshold, and output the virtual machine list to the VMM22; obtain the data flow rec...

Abstract

The embodiment of the invention provides a method and equipment for migrating virtual machines based on a network data flow direction, and a cluster system. Each network flow monitoring module of the cluster system is used for interacting with a virtual machine monitor (VMM) to acquire network flow information of each virtual machine on the current service node; a virtual machine deployment adjustment module is used for acquiring network flow information of the virtual machines from network flow monitoring modules on a plurality of service nodes in the cluster system, determining a data flow direction relation among the virtual machines in the cluster system according to the network flow information, and transmitting a virtual machine migration command or outputting a corresponding virtual machine migration suggestion to the VMM on which the determined virtual machines to be migrated are operated according to a virtual machine migration strategy and the data flow direction relation among the virtual machines in the cluster system; and a VMM unit is used for receiving the virtual machine migration command transmitted by the virtual machine deployment adjustment module and migrating the virtual machines to be migrated to a target service node. By the method and the equipment, communication flow among the virtual machines in the cluster system can be effectively reduced, and network burden is reduced.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a virtual machine migration method, device and cluster system based on network data flow. Background technique [0002] With the development of computer technology, virtualization technology has been more and more widely used. Among them, the most widely used virtualization segmentation technology is to run multiple virtual machines (Virtual Machine; VM) on a physical server, between the physical server and multiple VMs, through the virtual machine monitor (Virtual Machine Monitor; VMM) manages the central processing unit (Central Processing Unit; CPU), memory, storage, network and other peripheral resources. The VMM schedules and manages these physical resources, allocates these physical resources for multiple VMs, and realizes the communication between each VM. operate in isolation from each other. [0003] In order to effectively utilize the resources on each physical s...
