## Container with CPU constraint
The runtime calculates the number of vCPUs required by a container with CPU
constraints using the following formula: `(quota + (period -1)) / period`, where

`quota` specifies the number of microseconds per CPU Period that the container is
guaranteed CPU access and `period` specifies the CPU CFS scheduler period of time
in microseconds. The result determines the number of vCPU to hot plug into the
