Hypervisor Reporting Authority Design for Virtualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtualization environments, the consolidation of redundant reports from multiple hypervisor reporters leads to increased network traffic and processing burdens on monitoring nodes, hindering scalability and accuracy in maintaining information about virtual machines and hypervisors.
Innovation Solution
Designating a single hypervisor reporter as the current authority for each hypervisor, requesting a full initial report, and subsequently only differential reports, to eliminate redundant information and reduce network traffic and processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple hypervisor reporters generate reports about the same hypervisor, then comprehensive information is collected, but network traffic and processing loads increase
Solution Approach 1:
Multiple hypervisor reporters are merged into a single authoritative reporter per hypervisor. The system designates one reporter as the current authority that consolidates information from multiple sources, eliminating redundant report generation while maintaining comprehensive information collection.
Solution Approach 2:
The hypervisor reporter system is designed to be universal by allowing any reporter to potentially report on any hypervisor, but through the current authority mechanism, ensures only one reporter actively reports per hypervisor. This multi-functional design adapts to dynamic environments where reporters may join or leave.
2Reliability
If multiple hypervisor reporters generate reports about the same hypervisor, then comprehensive information is collected, but processing burden on monitoring node increases
Solution Approach 1:
The monitoring node processes reports from a single authoritative source per hypervisor rather than consolidating multiple redundant reports. This merging approach simplifies processing logic while maintaining information completeness through the current authority designation.
Solution Approach 2:
The system extracts the essential function of information collection from multiple reporters and concentrates it in a single current authority reporter. This extraction eliminates the need for complex consolidation logic at the monitoring node while preserving comprehensive information gathering.
3Loss of information
If a full report is requested from the current authority, then complete information is obtained, but initial network traffic is high
Solution Approach 1:
A full report is sent as a preliminary action when a hypervisor reporter is first designated as current authority, establishing the baseline information. Subsequent differential reports only transmit changes, significantly reducing ongoing network traffic while maintaining information completeness.
Solution Approach 2:
Instead of continuous full reporting, the system uses periodic differential reporting where only changes since the last report are transmitted. This periodic action with the current authority maintains information completeness while dramatically reducing network traffic compared to continuous full reports.
Data Source
AI summary
Mechanisms for efficient hypervisor reporting are disclosed. A first communication from a first hypervisor reporter is received that identifies a first hypervisor as a hypervisor about which the first hypervisor reporter can generate reports over time. It is determined that no other hypervisor reporter is a current authority for the first hypervisor. The first hypervisor reporter is designated as a current authority for the first hypervisor. A first full report is requested from the first hypervisor reporter about the first hypervisor.
