Nowadays there are a few works which are concerned with the virtualization technology and the fault-tolerance technology, because virtualization system can provide an environment allowing multiple operating systems running in concurrent way. In this paper, we based on a real-time hypervisor-XtratuM, propose the architecture of a fault-tolerant real-time control system (XFTRTS), which provide local backup execution and to support different level diversity including N-version programming on a single host. Furthermore, we implement a prototype of XFTRTS and test its important performance metric–latency, which is within two microseconds.
