1:问题的提出:
经常出现:
calcru: runtime went backwards from 8370817 usec to 8370811 usec for pid 435 (vmware-guestd)
经查找,得到解决办法:
2:问题产生原因:
The problem is likely that WMware doesn't correctly simulate the
timer we use to tickle softclock.
3:解决办法:
"sysctl kern.timecounter.hardware=TSC" may help you, if kernel uses ACPI-fast as a timecounter.
4:效果:
使用root执行了以下命令:
#sysctl kern.timecounter.hardware=TSC
kern.timecounter.hardware: ACPI-safe --> TSC
现在,系统不再出现calcru的提示了。
