Virtual machine resource management device, method and system

Abstract

The present invention relates to a device, method and system for managing resources of a virtual machine. The device comprises: a management rule generating module used for generating a virtual machine resource management rule according to the received user-defined virtual machine resource management parameters, the virtual machine resource management rule at least comprising a virtual machine resource change condition; a state information receiving module used for receiving state information about a virtual machine sent by a virtual machine monitoring module; and a resource allocation scheme generating module used for generating a resource allocation scheme for the virtual machine according to the state information about the virtual machine and the virtual machine resource management rule when the state information about the virtual machine meets the virtual machine resource change condition, wherein the resource allocation scheme for the virtual machine is used for updating the resource configuration of the virtual machine.

Description

technical field [0001] The present invention relates to virtual machine resource management in the field of IT technology, and in particular to a resource management device, method and system for virtual machines in a distributed virtual machine resource deployment scenario. Background technique [0002] Resource virtualization technology represented by cloud computing is one of the most active technical fields at present, and is widely used in communication, security, storage, Internet of Things and other fields. Resource virtualization technology virtualizes traditional hardware, network, computing and other resources into a "resource pool". When using resources in this resource pool, users can dynamically apply for them on demand, thereby minimizing user IT expenses. [0003] Resource virtualization technology requires an efficient virtual machine resource management mechanism. Taking cloud computing as an example, all systems based on cloud computing (hereinafter referr...

AI Technical Summary

Problems solved by technology

This method of allocating virtual machine resources based on user applications requires manual monitoring, evaluation, and application for re-allocation of resources when user business changes lead to insufficient or excess virtual machine resources, which is not only difficult to achieve in engineering or real-time Insufficient, and because this reallocation is based on manual evaluation, it cannot be completely consistent with the user's business load, and it cannot be completely "assigned on demand"
