Sorry, I forgot to add to this before.

If you want to use bridging in KVM you need to set up bridge interfaces 
on the host (br0 and so on) and assign the main IP address to that 
interface, instead of to the underlying physical one.

One more thing, if you assign a bridge to a VLAN interface, you do not 
need to add the VLAN on the guest, just treat it as a normal interface 
and the guest will take care of the tagging for you.
