because one of the veth devices will be seen in the host.so we can set tc rules on this

I want to know if it's necessary to limit container's network bandwidth when the
container
uses a physical nic device. because this nic device is only used by this container.
And if this is necessary,Be there any good idea?
Thanks!
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.
