This add vlan=XXX to network interfaces config. I have succesfully tested it with eth0--vmbr0 eth0- |bond0--vmbr0 eth1- eth0.X--vmbr0vX eth0 |bond0.X--vmbr0vX eth1 I'll do more test with vlan over bonding this week, with iperf to see if I dont have packet loss. I'm currently testing bonding in active-backup mode
