One question I still have, is the network-manager packages installed?

So you are asking for a bridge that doesn't have an external address, and
further, you want the domU to get an address through that bridge right?

I don't know if it is possible or not, but you could do a simple test to see

add the following to your /etc/network/interfaces

auto br0
  bridge_ports eth0
  bridge_fd 9
  bridge_hello 2
  bridge_maxage 12
  bridge_stp offi

eth0 can be replaced with any eth* that you want to use as your
bridge port.

Then configure a test domU to use bridge=br0 as its vif option.

If the domU can get an address and get out, then you are successful,
If it can't then my best guess is that it probably won't work (or there is
another way that I don't know about)

Hope that helps,
Cheers,
Todd
