摘要：
According to one embodiment, a virtual machine manager (VMM) virtualizes hardware including a CPU to construct a plurality of virtual machines. A plurality of guest OSes are executed on the respective virtual machines. A detector included in VMM detects a change in the operating frequency of CPU. A scheduler is included in VMM. If a change in operating frequency is detected, and the operating frequency decreases below a prescribed frequency, the scheduler performs scheduling so as to increase a time for which the CPU is to be allocated to one or more predetermined particular guest OSes of the plurality of guest OSes.
