Virtual machine system, hypervisor in virtual machine system, and scheduling method in virtual machine system

Attempts are made to reduce the system overhead generated at the time of context save/restore processing to perform process switching in a virtual machine system. In a CPU occupancy mode that a physical CPU is exclusively allocated to virtual machines, a logical CPU process running on the physical CPU is static, so that it is not necessary to save/restore the context every time the processes are switched. When a switching source process is a logical CPU process in a CPU occupancy mode, a context save is temporarily suspended. When switching to the same logical CPU process is made again continuously, save/restore is skipped. When the logical CPU process of a VMM control VM runs in that period, the logical CPU process whose save is delayed is recorded and saved late.
