摘要： A hypervisor calculates the total number of processor cycles (the number of processor cycles of one or more physical processors) in a first length of time based on the sum of the operating frequencies of the respective physical processors and the first length of time for each first length of time (for example, a scheduling initialization cycle T1, which will be explained further below). The hypervisor calculates for each virtual computer the number of possessing cycles, which is a value obtained by the total number of processor cycles being distributed in proportion to the service ratios of multiple virtual computers. In virtual processor scheduling, the hypervisor runs a virtual processor inside a virtual computer on any physical processor based on the number of hold cycles of each virtual computer.

摘要： 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.
摘要翻译：尝试减少在上下文保存/恢复处理时产生的系统开销，以在虚拟机系统中执行进程切换。在物理CPU被分配给虚拟机的CPU占用模式下，在物理CPU上运行的逻辑CPU进程是静态的，因此在每次进程切换时不需要保存/恢复上下文。当切换源进程是CPU占用模式下的逻辑CPU进程时，上下文保存被暂停。当切换到相同的逻辑CPU进程再次连续进行时，将跳过保存/恢复。当VMM控制VM的逻辑CPU进程在该时间段内运行时，保存延迟的逻辑CPU进程被记录并保存得较晚。

摘要： Each virtual computer is arranged to have an exclusive-use timer mechanism in a physical computer in the form of a virtual timer with a physical timer as a timer source. Upon execution of virtual computer scheduling processing, a hypervisor uses information, such as “virtual timer value” or “accumulation of processor usage times” of each virtual computer, to perform dispatching while determining a virtual computer to be dispatched by priority and computing its dispatch time. With this approach, a scheduling method capable of simultaneously satisfying “(1) least possible interruption delay,” “(2) uniformization of accumulation of processor use times of each virtual computer” and “(3) effective use of processor idle time” is provided. In particular, regarding the requirement (1), the function of causing a report to virtual computer upon at the time of timer interruption to become zero in delay is realized.
