VM Migration Triggered by Host Memory Crash Probability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a memory failure occurs in a host machine, existing systems cause all virtual machines on the host machine to stop providing services, leading to decreased user experience and quality of service.
Innovation Solution
Detect memory failures in host machines, determine the crash probability based on failure parameters, and transfer virtual machines to a target host machine with a lower crash probability when the probability exceeds a predetermined threshold, thereby avoiding service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all virtual machines on the host machine are stopped when memory failure occurs, then system stability is maintained, but service continuity deteriorates
Solution Approach 1:
The system segments the host machine into multiple independent virtual machines, allowing selective migration of affected VMs while leaving others running. This segmentation enables partial service continuity even when memory failure occurs on the host machine.
Solution Approach 2:
The system performs preliminary health assessment of candidate host machines before migration, and pre-establishes migration capabilities. When memory failure occurs, VMs can be quickly migrated to pre-validated healthy hosts, maintaining service continuity without complete system shutdown.
2Productivity
If virtual machines are migrated to avoid crash failure, then service continuity is maintained, but system complexity increases
Solution Approach 1:
The system implements automated health assessment, crash probability calculation, and migration decision-making without requiring manual intervention. The virtualization management system self-monitors memory health metrics and autonomously triggers migration when thresholds are exceeded, reducing operational complexity.
Solution Approach 2:
The system continuously monitors memory failure parameters and crash probability, using this feedback to dynamically adjust migration decisions. Health assessment results and service continuity metrics feed back into the migration management system to optimize future decisions, creating a self-regulating mechanism.

AI summary
A method and an apparatus for handling a memory failure is provided. The method includes: in response to detecting a failure occurring in memory of a host machine, acquiring (101) a failure parameter of the memory, determining (102) a crash probability of the host machine based on the failure parameter, and transferring (103) all virtual machines on the host machine to a target host machine when the crash probability is greater than or equal to a first predetermined threshold. A crash probability of the target host machine is less than a second predetermined threshold. The second predetermined threshold is less than the first predetermined threshold. Further, an electronic device and storage medium are provided.
