Hypervisor Guest Status Collection via Intermediary Virtual Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtualized systems, hypervisors face challenges in effectively communicating user-specific information to virtual machine users, as they need to access and manage user status without disturbing the virtual machine operations.
Innovation Solution
The method involves booting an information collection guest from the hypervisor media library, exposing it to the virtual machine memory, detecting the guest status, generating an information message, and sending it to a message display agent to ensure targeted information delivery to the user, while managing the display through a virtual graphics card to force the overlay onto the user's screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the hypervisor directly accesses virtual machine memory to collect guest status, then information collection efficiency is improved, but the virtual machine operation stability deteriorates
Solution Approach 1:
The patent introduces an information collection guest as an intermediary component that runs within the virtual machine environment. This guest acts as a mediator between the hypervisor and the virtual machine memory, collecting status information without direct hypervisor access. The intermediary approach maintains virtual machine encapsulation and operational stability while enabling efficient information gathering through controlled interactions.
Solution Approach 2:
The system segments the information collection function into a separate virtualized guest environment rather than implementing it directly in the hypervisor. This segmentation isolates the collection process from the core virtual machine operations, allowing independent execution and reducing interference. The collected information is then transmitted through controlled interfaces, maintaining system stability.
2Reliability
If the hypervisor forces overlay display to ensure information delivery, then information delivery reliability is improved, but user control flexibility deteriorates
Solution Approach 1:
The display overlay mechanism implements dynamic behavior by allowing users to configure overlay preferences and control parameters. The system adapts between forced overlay display for critical information and user-controlled display options for non-critical notifications. This dynamic approach ensures reliable delivery of important status information while maintaining user flexibility for routine communications.
Solution Approach 2:
The system changes display parameters based on information priority and user preferences. Critical alerts use forced overlay display with high visibility parameters, while routine notifications allow user-configurable display options. The overlay position, timing, and persistence parameters are dynamically adjusted based on the nature of the information being conveyed, balancing reliability and user control.

AI summary
The present disclosure provides new and innovative methods and systems for guest status collection in a virtual environment. An example method includes accessing a hypervisor media library and booting an information collection guest from the hypervisor media library. The method may also include exposing the information collection guest to a memory of a virtual machine, detecting a first guest status of the virtual machine, generating an information message based on the first guest status, and sending the information message to a message display agent.
