Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current virtual machine password reset methods require technical expertise, are complex, and consume additional virtual machine resources, necessitating manual operations and auxiliary virtual machines.

Innovation Solution

A method where a virtual machine sends a password obtaining request to a cloud service computing node, which queries a metadata server to retrieve and return a reset password, allowing the virtual machine to automatically configure the new password without user intervention or additional resource consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the traditional manual password reset method is used, then the user can reset the virtual machine password, but the user needs technical expertise and the operation is complex

Engineering Contradiction:

Improveease of password reset operationVSAvoidcomplexity of password reset process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The virtual machine performs password reset automatically without requiring user intervention. The system uses metadata storage to store reset passwords and the virtual machine autonomously retrieves and applies the password, eliminating the need for user technical expertise and manual operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A metadata server acts as an intermediary between the user and the password reset process. The metadata server stores reset passwords and provides them to the virtual machine through standardized interfaces, simplifying the overall process while maintaining security

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the traditional manual password reset method is used, then the user can reset the virtual machine password, but additional virtual machine resources are consumed

Engineering Contradiction:

Improveease of password reset operationVSAvoidvirtual machine resource consumption

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The password reset function is extracted from the virtual machine environment and placed in a centralized metadata server. This eliminates the need for auxiliary virtual machines and reduces resource consumption by using lightweight data storage and retrieval operations

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of creating a copy of the virtual machine in an auxiliary VM, the system stores password reset information as metadata and retrieves it when needed. This approach avoids the resource-intensive process of spinning up additional virtual machine instances

Inventive Principle:

Principle #26Copying

AI summary

A virtual machine password reset method includes a virtual machine first sending a password obtaining request to a cloud service computing node, the cloud service computing node querying a reset password of the virtual machine in a metadata server based on the password obtaining request, the cloud service computing node returning a password obtaining response based on a result of querying the reset password of the virtual machine in the metadata server, the virtual machine configuring the reset password as a password of the virtual machine, to complete virtual machine password reset.
