    // Processor object
    // #1463: Showing the CPU can make the guest do bad things on it like SpeedStep.
    // In this case, XP SP2 contains this buggy Intelppm.sys driver which wants to mess
    // with SpeedStep if it finds a CPU object and when it finds out that it can't, it
    // tries to unload and crashes (MS probably never tested this code path).
    // So we enable this ACPI object only for certain guests, which do need it,
    // if by accident Windows guest seen enabled CPU object, just boot from latest
    // known good configuration, as it remembers state, even if ACPI object gets disabled.
