After rebooting guest, CPPC initialization failed because _CST and _CPC missed in DSDT table. When writing _CST and _CPC in DSDT table, it gets cx_cnt or px_cnt as condition. Getting cx_cnt or px_cnt triggers the hypercall hcall_get_cpu_pm_state. The hypercall hcall_get_cpu_pm_state uses VM_CREATED as VM state's condition. While, after rebooting guest, the VM state is VM_PAUSED when writing _CST and _CPC in DSDT table. Therefore, changing VM state's condition from VM_CREATED to VM_CREATED or VM_PAUSED for hcall_get_cpu_pm_state can solve the CPPC initialization failed issue after rebooting guest.
