I have tried your setup on my machine with the following host
configuration:<br>
<br>
<tt># brctl show<br>
bridge name bridge id STP enabled interfaces<br>
br0 8000.001a64d00016 no eth0<br>
virbr0 8000.000000000000 yes <br>
</tt><br>
If I use the configuration as you have shown it doesn't work for me,
either. However, if I use<br>
<br>
<source dev='br0' mode='bridge'/><br>
<br>
then it works as expected. Do you happen to have a similar
configuration on the host with the interface the macvtap device
wants to use as 'source' being bridged? <br>
