RodosVisor - an Object-Oriented and Customizable Hypervisor: The CPU Virtualization

RodosVisor is an object-oriented and bare-metal virtual machine monitor (VMM) or hypervisor designed for the aerospace industry, mainly to provide time and spatial separation to the NetworkCentric core avionics machine, Montenegro and Dittrich (2009). The NetworkCentric core avionics machine consists of several harmonized components working together to implement dependable computing in a simple way, with computing units managed by the local real-time operating system RODOS. To support partitioned software architectures such as AIR, Rufino et al. (2009), and MILS, DeLong, R. (2007), RodosVisor adapted the Popek and Goldberg’s fidelity, efficiency and resource control virtualization requirements, Popek and Goldberg (1974), to the space application domain by extending them with extra ones, like timing determinism, reactivity and improved dependability. Another distinctive RodosVisor feature is the customized design based on generative programming techniques, such as aspect oriented programming and template meta-programming.
