What documentations have you read?

One of them, yes. Not the only one.

Because that's the easiest setup to start with. Similar to vbox's NAT
networking.

Did you read "Networking" section on
https://help.ubuntu.com/lts/serverguide/lxc.html ?

Again, what documentations have you actually read?

The basics should be explained in the link I sent, including how to "bridge
the host's network interfaces".

The networking setup (e.g. bridge-with-nat, or bridge-host-interface) is
generic, in that it applies to lxc, xvm, xen, whatever.
