> What's your bridge setup/configuration?

not sure what you want here, i just followed the guide at
https://help.ubuntu.com/community/KVM/Networking#bridgednetworking to
get everything set up

my /etc/network/interfaces and ifconfig:

$ cat /etc/network/interfaces
# 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

# The primary network interface
auto eth0
iface eth0 inet dhcp

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