HIERARCHICAL SCHEDULER FOR A VIRTUAL MACHINE AND A METHOD FOR SCHEDULING THE VIRTUAL MACHINE CAPABLE OF SATISFYING BOTH REAL TIME CHARACTERISTIC AND NON-REAL TIME CHARACTERISTIC

摘要

PURPOSE: A hierarchical scheduler for a virtual machine and a method for scheduling the virtual machine are provided to schedule both a real time virtual machine and a non-real time virtual machine by hierarchically forming a real time scheduler and a non-real time scheduler based on an interfacial virtual machine.;CONSTITUTION: A first scheduler(201) schedules an interfacial virtual machine representing a real time virtual machine and a non-real time virtual machine according to a real time scheduling policy. A second scheduler(202) is called by the interfacial virtual machine. The second scheduler schedules the non-real time virtual machine according to a non-real time schedule policy. A first queue(203) stores the real time virtual machine and the interfacial virtual machine. The first queue is managed by the first scheduler.;COPYRIGHT KIPO 2012
