Virtual Machine Thread Switching for Privacy Isolation

The patent creates a copy of the vCPU thread structure to enable resource sharing. Specifically, it creates a thread group that copies the parent vCPU thread's binding settings to multiple child vCPU threads, allowing multiple virtual machines to share the same physical computing core resources while maintaining independent management control. This copying mechanism reduces overhead by reusing existing thread configurations rather than creating entirely new thread structures.

The patent segments the vCPU thread into a hierarchical structure with a parent vCPU thread and multiple child vCPU threads. This segmentation allows the system to divide CPU resource management into manageable units where the parent thread handles binding settings and child threads represent different virtual machine instances sharing those resources. This segmentation reduces management complexity by organizing resources in a tree structure rather than managing flat, independent thread objects.

The patent performs preliminary action by pre-establishing a thread group structure with inherited binding settings before virtual machines need to use the resources. The parent vCPU thread's binding configuration is copied to child threads in advance, enabling efficient resource allocation. When adjustments are needed, the system has already prepared the hierarchical structure that facilitates centralized control through the parent thread.

The patent inverts the traditional management approach by making the parent vCPU thread the central control point rather than managing each child thread independently. Instead of adjusting settings on each child thread when modifications are needed, the system adjusts the parent thread's binding settings, and these changes are automatically propagated to all child threads. This inversion simplifies control by reversing the direction of configuration management from bottom-up to top-down.
