* Network rate must be multiplied by 125 not 128
In a libvirt domain xml when nw_rate=5000 the kilobytes per second
configured in the interface is 640000 which is 5.12 Gbit/s. Which is
more than the configured network rate of 5Gbit/s. So instead multiply by
125.
* Apply suggestions from code review
