VM Shutdown Management via File Lock Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computing environments, conflicts arise when multiple virtual machines request access to the same file, leading to resource overhead due to file locks, and existing solutions fail to efficiently manage virtual machine shutdowns and resource allocation based on priority and lock ownership.
Innovation Solution
A method is implemented to identify virtual machine files with locks, prioritize virtual machines, and manage resource allocation by stopping execution of virtual machines without locks and reallocating resources to higher-priority ones, using a management service that monitors file requirements and lock metadata to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If files are locked in a file system to prevent conflicts when multiple virtual machines request access to the same file, then file access conflicts are resolved, but additional computing resource overhead is consumed by processes attempting to access locked files
Solution Approach 1:
The patent extracts the resource overhead problem by identifying and stopping virtual machine processes that are attempting to access locked files. The management service monitors file access requests and terminates virtual machines that would cause conflicts, thereby removing the source of computing resource overhead while maintaining file lock integrity
Solution Approach 2:
The patent implements a feedback mechanism where the management service continuously monitors file lock status and virtual machine access requests. When a lock conflict is detected, the system provides feedback by stopping the conflicting virtual machine process, creating a closed-loop control system that dynamically adjusts resource allocation based on real-time file access conditions
2Use of energy by moving object
If virtual machines are stopped to resolve file lock conflicts, then computing resource overhead is reduced, but virtual machine execution continuity is interrupted
Solution Approach 1:
The patent applies preliminary action by having the management service proactively monitor and identify potential file lock conflicts before they occur. By detecting lock status in advance and pre-stopping virtual machines that would cause conflicts, the system prevents execution interruptions rather than reacting after conflicts arise, thereby reducing the perceived time loss
3Productivity
If resources are reallocated from one virtual machine to another based on priority, then resource utilization efficiency is improved, but system complexity increases due to priority management
Solution Approach 1:
The patent applies universality by designing the management service to perform multiple functions: monitoring file locks, identifying conflicting virtual machines, stopping processes, and reallocating resources. This multi-functional approach consolidates complexity into a single management component rather than distributing it across multiple specialized systems, thereby improving resource utilization while containing overall system complexity

AI summary
Described herein are systems, methods, and software to manage virtual machine shutdowns in a computing environment. In one example, a management service identifies a virtual machine file in a file system associated with a first virtual machine and one or more additional virtual machines and identifies a lock on the virtual machine file by the first virtual machine. The management service further stops execution of the one or more additional virtual machines in response to identifying the lock.
