Yup, build a traditional bridge instead of using qemu's 'default' virbr0
NAT'ed bridge.
I do it this way:

You can ignore the bonds if you're not using them, and just put the
'BRIDGE="vbrX"' in the ethX file. Move the IP from the ethX to vbrX.
With that, your VMs will effectively be on the same network, no
translation, and the bridge will act just like another switch on your
network.
