1. a method for cpu power management in computer system, is characterized in that, comprising:

  • Be the first client operating system simulation virtual center processor VCPU;

    According to the power management demand of predetermined described VCPU, configure the power management states that described VCPU supports, comprising;

    configure the first low power consumpting state that described VCPU supports, identical with the second low power consumpting state that the physical cpu of described computer system is supported;

    Configure the first performance management function that described VCPU supports, to report the second performance management function supported identical with the CPUID of described physical cpu;

    And the process resource relevant to the open described power management states of described first client operating system;

    In the start-up course of described first client operating system, report the power management states of described VCPU support to described first client operating system;

    In the operational process of described first client operating system, according to the first power management policy of described first client operating system current setting, by performing corresponding power management to described VCPU, control the current power supervisor status of the physical cpu of described computer system.
