Also, looks like the network traffic is bridged at dom0, does that mean
dom0 can see all the network traffic to all domU?
I'm not sure I fully understand your questions.

dom0 feeds each domU's console input. The current source of that input is a TCP socket via Xend.

All network traffic is funnelled through the network device's backend which currently lives in dom0.

If the answers to the two questions above are "yes", can someone point me
to the right place in source codes that bridge user terminal inputs and
network traffic?
It depends on what you're trying to do. If you want to do some sort of traffic shaping or routing the normal Linux hooks should work in dom0.

If you want to trap console input, you're probably going to be looking in Xend.

Regards,

Many thanks!
