Virtual Machine Processor Isolation for Cloud Speed

The patent introduces a virtual processor as an intermediary layer between the physical processor and the application program. The virtual processor receives instructions from the application program and translates them into physical processor instructions, enabling the physical processor to execute instructions for multiple virtual machines while maintaining isolation. This mediator approach allows the physical processor to efficiently manage multiple virtual environments without requiring full software simulation for each, thus improving data processing speed while preserving isolation capabilities.

The patent replaces the mechanical software simulation approach with a more efficient instruction translation mechanism. Instead of using software to fully simulate hardware instructions (which is slow), the system uses a virtual processor that directly translates virtual machine instructions into physical processor instructions, leveraging the physical processor's native execution capabilities. This substitution of the execution mechanism maintains hardware isolation while dramatically improving data processing throughput.

The patent makes the physical processor universal by introducing the virtual processor layer. The physical processor can function as a dedicated processor for a specific virtual machine when needed, or it can be dynamically allocated to different virtual machines based on workload demands. The virtual processor acts as a flexible interface that allows the same physical processor to serve multiple virtual machines sequentially or concurrently, achieving both high performance for individual virtual machines and efficient resource allocation across multiple virtual machines.
