<p class=MsoNormal><span lang=EN-US>First, I connected the switch and server

<p class=MsoNormal><span lang=EN-US>When I use sub-interface eth1.12 for
vlan12,br12 bridged to eth1.12, and then using tap0 ..tapN, the qemu guest networking
works fine.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>But when I use br1 bridged to eth1 without
sub-interface, also use tap0… tapn , it does not work. <o:p></o:p></span></p>
