Today in both virtualized and non-virtualized systems the entire I/O functionality is based on device drivers. They are central to any system structure; both anecdotal and informed evidence indicates device drivers as a major source of trouble in the classical OS and a source of scaling and performance issues in virtual I/O, due to "trusted intermediary" required for the shared I/O. We propose an architecture which virtualizes the entire I/O subsystem rather than each I/O device, and provides device-independent I/O at higher level of abstraction than the traditional I/O interfaces. In our suggested architecture the system robustness is increased by isolating drivers; efficient and scalable virtualization becomes possible by a complete separation of the I/O and compute function and introducing a protection model that does not require a trusted intermediary for I/O.
