Secure VM Throttle Control for Guest Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual machine communication technologies fail to effectively manage resource utilization across guest virtual machines, leading to overconsumption of resources on physical platforms, as guest virtual machines lack information about available resources and the state of other virtual machines.
Innovation Solution
Implementing a method for inter-virtual machine communication using tagged control blocks that allow a secure virtual machine to monitor platform environment attributes and adjust resource usage by setting throttle values in guest virtual machines, specifically for processes like virus scanning and antivirus updates, to reduce resource consumption when thresholds are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If guest virtual machines are configured to use more resources than physically available, then resource utilization flexibility is improved, but resource overconsumption occurs leading to system instability
Solution Approach 1:
The patent implements a feedback mechanism where the secure virtual machine continuously monitors resource consumption by guest virtual machines and platform environment attributes. When resource thresholds are exceeded, the system sends feedback signals to throttle resource usage, creating a closed-loop control system that maintains stability while allowing flexible resource allocation
Solution Approach 2:
The secure virtual machine acts as an intermediary between the guest virtual machines and the physical platform resources. It mediates resource access by monitoring consumption patterns and enforcing throttle values, preventing direct overconsumption while maintaining the illusion of abundant resources for guest VMs
2Ease of operation
If guest virtual machines lack information about available resources, then resource management autonomy is improved, but resource overconsumption occurs
Solution Approach 1:
The secure virtual machine serves as an intermediary information source, providing guest virtual machines with controlled knowledge about resource availability through monitored platform environment attributes, enabling informed resource usage decisions without compromising guest autonomy
Solution Approach 2:
The system provides feedback to guest virtual machines about resource consumption status and throttle values, allowing them to adjust their behavior autonomously based on platform conditions while maintaining overall resource balance
3Adaptability or versatility
If resource-intensive processes are allowed to run without restriction, then process execution freedom is improved, but system performance deteriorates under resource constraints
Solution Approach 1:
The patent implements dynamic throttle values that adjust resource allocation for processes based on real-time platform conditions. Resource-intensive processes can execute freely when resources are abundant, but automatically receive throttled allocation when platform capacity is constrained, optimizing overall system performance
Solution Approach 2:
The system changes the throttle parameter dynamically based on platform environment attributes and resource consumption patterns, allowing process execution freedom to vary with system conditions rather than being fixed, thereby maintaining performance under varying loads
