DNS is just a cherry on the cake, first you need to establish the network
connection.
I'm not using netctl for some time, but I'm pretty sure it does not launch any
DHCP server. If you want to use DHCP, you will need to start the server on your
own.
I have written several scripts [1-4] to manage a bridge interface for QEMU VMs,
see if you can reuse some of it. Especially [2] might be useful for you, though
you probably do not need to create the tap interface. Note that the original
author of [3] and [4] is Xyne, see his excellent tutorial [5].
