cpu utilization problem displayed by top

When the physical machine has multiple virtual machines, use top on the physical machine to check the CPU utilization rate, and the utilization rate is far below 100%. procps-ng version is v4.0.0.

eg:

%cpu0 : 46.2 us, 3.9 sy, 0.0 ni, 4.5 id, 0.0 wa, 0.6 hi, 0.6 si, 0.0 st

%cpu1 : 44.7 us, 5.7 sy, 0.0 ni, 7.9 id, 0.0 wa, 0.8 hi, 0.6 si, 0.0 st

And version 3.3.17 does not have this problem.
