This paper presents GearV, a two-gear lightweight hypervisor architecture to address the some known challenges. By dividing hypervisor into some partitions, and dividing scheduling policies into Gear1 and Gear2 respectively, GearV creates a consolidated platform to run best-effort system and safety-critical system simultaneously with managed engineering effort. The two-gears architecture also simplifies retrofitting the virtualization systems. We believe that GearV can serves as a reasonable hypervisor architecture for the mix-critical IoT systems.
