Interesting use case. My experience has been in the past that packets tcpreplay/tcpbridge send on a host are not visible by that host's IP stack. So to make this work, you'd have to run tcpbridge on the guest host. Using a TAP interface should be able to work in theory, but I think it would require some changes in my sendpacket.[ch] code to support those devices properly. I'll open a feature ticket in trac to see about adding that, but right now I couldn't even guess when something like that might be done by me.
