the name 'eth0' normally means wired nic. However, they stopped using 
the names eth0, eth1, etc. a while ago and now use names based on the 
nic you have. So, you need to find the name and use that.

My bridges don't need an ip address, so I would substitue 'iface br0 
inet manual'

Your /etc/network/interfaces should look more this:


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto br0
iface br0 inet dhcp
         bridge_ports eth0
         bridge_stp off
         bridge_fd 0
         bridge_maxwait 0
