Virtual Machine Image Migration via Platform-Specific Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual machine migration technologies face challenges in implementing efficient cross-platform offline migration due to differences in underlying implementation technologies, leading to low migration efficiency and the need for manual user intervention.
Innovation Solution
A method and apparatus for virtual machine migration that involves downloading an image file from object storage, processing it with a preset command configured for the source and destination virtualization platforms, and provisioning a virtual machine on the destination platform, which includes modifying disk partition names, converting formats, and loading or importing required drivers, thereby enabling automatic migration without manual user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static migration method is used for cross-platform virtual machine migration, then the migration can be implemented between different virtualization platforms, but the migration efficiency is low and manual user intervention is required
Solution Approach 1:
The patent applies preliminary action by pre-configuring conversion commands for different virtualization platform combinations. The system stores multiple conversion commands in advance, each corresponding to a specific source-destination platform pair, and automatically selects and executes the appropriate command during migration, eliminating the need for manual intervention and improving migration efficiency while maintaining cross-platform capability
Solution Approach 2:
The patent implements self-service by enabling the migration system to automatically detect the source and destination virtualization platforms, select the appropriate conversion command from the pre-configured set, and execute the migration process without requiring manual user input. The system autonomously completes the entire migration workflow, including platform identification, command selection, and migration execution
2Ease of operation
If manual user operations are required for virtual machine migration, then the migration process can be customized and controlled, but the migration efficiency is reduced and time consumption increases
Solution Approach 1:
The patent applies self-service by designing an automated migration system that performs all migration operations without requiring manual user intervention. The system automatically detects platform types, selects appropriate conversion commands, and executes the migration process autonomously, significantly reducing migration time while maintaining operational control through pre-configured command sets
3Adaptability or versatility
If different virtualization platforms use different implementation technologies, then each platform can be optimized for its specific requirements, but cross-platform migration becomes difficult and complex
Solution Approach 1:
The patent applies segmentation by dividing the migration solution into distinct components: a database storing conversion commands for different platform pairs, a detection module for identifying source and destination platforms, and an execution module for running the appropriate conversion command. This segmented architecture manages complexity by organizing platform-specific conversion logic into discrete, selectable units
Solution Approach 2:
The patent implements universality by creating a unified migration framework that can handle multiple virtualization platform combinations through a single system. The framework stores multiple conversion commands that can be selectively applied based on the detected platform pair, enabling one system to serve multiple platform migration needs without requiring separate migration tools for each platform combination
Data Source
AI summary
A virtual machine migration method and apparatus, that the method includes: downloading an image file of a to-be-migrated virtual machine from an object storage; starting a preset command to process the downloaded image file, to obtain a private image corresponding to the image file of the to-be-migrated virtual machine, and provisioning, by using the private image, a virtual machine that runs on a destination virtualization platform, where the preset command is configured based on a difference between a source virtualization platform and the destination virtualization platform. According to the foregoing method, the image file of the to-be-migrated virtual machine is processed by executing the preset command, so that automatic migration of the image file of the to-be-migrated virtual machine can be implemented, and a user does not need to perform a manual operation. This effectively improves migration efficiency and meets a user requirement.
