Well, that depends. If you expect you guest to consume all bandwidth
then you need to set a floor on root eth. Guest is then still able to
use the full bandwidth, however if there are some packets for the host
those get prioritized. In general, it's a good idea, but to tell for
sure one should learn more about your usage scenario.
