VM Migration via Prioritized Storage Parameter Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud environments, migrating virtual machines to new host nodes often results in performance degradation due to unverified storage resource compatibility, leading to unsatisfied service level agreements for storage performance and security, as existing mechanisms lack automatic verification of storage and network configurations.
Innovation Solution
A method for running virtual machines on destination host nodes involves requesting prioritized target configuration parameters, checking actual configuration parameters, and selecting the host node based on these priorities, allowing for flexible operation while maintaining compliance with service level agreements by considering configuration weight costs and allowing deviations within specified percentages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual machine migration is performed without verifying storage resource compatibility, then migration speed and operational flexibility are improved, but storage performance and service level agreements deteriorate
Solution Approach 1:
The system performs preliminary verification of storage resource compatibility by checking actual configuration parameters against target configuration parameters before completing the virtual machine migration. This preliminary action ensures that storage performance requirements are met while maintaining fast migration speeds, resolving the contradiction between migration speed and storage performance reliability.
2Reliability
If strict verification of all configuration parameters is performed, then service level agreement compliance is improved, but deployment flexibility and operational capacity worsen
Solution Approach 1:
The system applies different verification strictness levels to different configuration parameters based on their importance. Critical parameters such as storage performance and security are verified strictly to ensure service level agreement compliance, while less critical parameters allow for greater flexibility. This local differentiation resolves the contradiction between strict compliance and deployment flexibility.
Solution Approach 2:
The system dynamically adjusts verification thresholds and acceptance criteria for configuration parameters based on service level agreement requirements and operational context. By changing parameter verification standards rather than applying uniform strict verification, the system maintains compliance with critical service level agreements while preserving deployment flexibility for non-critical parameters.
3Measurement precision
If manual verification of storage configuration is performed, then accuracy of parameter checking is improved, but operational complexity and time consumption worsen
Solution Approach 1:
The system implements automated self-verification of storage configuration parameters by having the storage resource manager automatically check actual configuration parameters against target configuration parameters. This self-service mechanism maintains high measurement precision for parameter checking while eliminating manual verification complexity and time consumption, resolving the contradiction between accuracy and operational complexity.

AI summary
The present invention relates to a method for running a virtual machine on a destination host node in a computer cluster, comprising the steps of requesting (S101) a set of target configuration parameters assigned to the virtual machine, wherein the target configuration parameters have prioritizations; requesting (S102) a set of actual configuration parameters of the destination host node for checking against the requested set of target configuration parameters; and running (S103) the virtual machine on the destination host node, if the set of actual configuration parameters of the destination host node falls within the set of target configuration parameters, wherein when selecting destination host node, the prioritization of the target configuration parameters is considered.
