名称描述
kvm_get_wallclockThe wallclock is the time of day when we booted. Since then, some time may* have elapsed since the hypervisor wrote the data. So we try to account for* that with system time
kvm_clock_read
kvm_get_tsc_khzIf we don't do that, there is the possibility that the guest* will calibrate under heavy load - thus, getting a lower lpj -* and execute the delays themselves without load
