You've got two physical devices on this single bridge. I don't know if
that is problematic but it is a bit unusual and might require other
tweaks to the network configuration.

Can you try with just one or the other device and see if that helps.

Once you've confirmed that and if you still want to make use of both
physical devices then you should use the bonding driver to link the two
devices and then put the bondN device on the bridge.

If that doesn't help then can you tell us where on the network your DHCP
server and gateway are (are they in dom0, elsewhere on the network etc).
Are you able to ping domU->dom0 and domU->gateway?

Ian.
