VM Migration Strategy for Resource Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud computing environments, virtual machines cannot be created when idle resources on individual physical hosts do not meet the resource requirements, despite total idle resources across multiple hosts being sufficient, leading to high costs and low resource utilization.
Innovation Solution
A method and apparatus for generating a virtual machine migration strategy that acquires resource information and service information from multiple physical hosts, determining a strategy to migrate virtual machines from hosts with insufficient idle resources to those with adequate resources, ensuring the resource requirement is met without adding new physical hosts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual machine creation is attempted on individual physical hosts when total idle resources are sufficient but individual hosts have insufficient resources, then the system maintains distributed resource allocation, but virtual machine creation fails and resource utilization is low
Solution Approach 1:
The patent merges idle resources from multiple physical hosts by selecting target virtual machines for migration from hosts with insufficient idle resources to hosts with sufficient resources, effectively combining dispersed idle resources into usable allocations that meet virtual machine requirements
Solution Approach 2:
The system dynamically identifies and responds to resource allocation opportunities by continuously monitoring idle resource distributions across physical hosts and automatically triggering migration strategies when favorable conditions arise, transforming static resource constraints into dynamic allocation opportunities
2Productivity
If new physical hosts are added to meet resource requirements, then virtual machine creation succeeds, but system cost increases
Solution Approach 1:
The patent merges idle resources from multiple existing physical hosts through coordinated virtual machine migration, creating sufficient contiguous resource blocks on target hosts without requiring additional physical hardware, thereby avoiding the cost of expanding the physical host infrastructure
3Loss of energy
If virtual machines are migrated to integrate resources across physical hosts, then resource utilization improves, but system complexity increases
Solution Approach 1:
The system implements self-service through automated identification of migration opportunities, automatic selection of source and target hosts based on resource states, and autonomous execution of migration strategies without requiring complex manual intervention or oversight mechanisms
Solution Approach 2:
The patent changes the operational parameters of physical hosts by migrating virtual machines between them, transforming the resource allocation state from insufficiently distributed to optimally utilized, while using configurable parameters like migration thresholds and host selection criteria to control complexity

AI summary
According to a method for processing virtual machine migration, in a case where idle resources on each single one of multiple physical hosts in a system do not meet a resource requirement from a virtualized network function (VNF) but total idle resources on the multiple physical hosts meet the resource requirement from the VNF, a virtual machine migration strategy is determined according to resource information about resources currently occupied on each of the multiple physical hosts and corresponding service information, and live migration may be performed on virtual machines.
