Abstract

A control unit including at least one processor and at least one memory connected to the at least one processor, a virtualization system, the virtualization system including a scheduler for scheduling a plurality of virtual machines to assign processing time to each of the virtual machines according to a predetermined fixed sequence of virtual machine switches forming a cycle period, which is repeated, the cycle period being the minimum time period after which the scheduling is repeated, wherein the virtualization system and the plurality of virtual machines are real-time systems, the virtual machines having respectively at least one real-time attribute, wherein at least one the real time attribute of a first virtual machine are different to the corresponding real-time attribute(s) of a second virtual machine, wherein predetermined fixed sequence of virtual machine switches is calculated based on the at least one real time attribute.
