Abstract
Hardware interrupts are routed to one of multiple processors of a virtualized computer system based on priority values assigned to the codes being executed by the processors. Each processor dynamically updates a priority value associated with code being executed thereby, and when a hardware interrupt is generated, the hardware interrupt is routed to the processor that is executing a code with the lowest priority value to handle the hardware interrupt. As a result, routing of the interrupts can be biased away from processors that are executing high priority tasks or where context switch might be computationally expensive.
