Hello,
Everybody,  I have a problem ,  I developed a component based on nox (like 
pyswitch in nox), the enviroment as follow gragh, the three VMs connect the ovs 
, the nox component  is the ovs's controller , when VM1 connect to HOST, I add 
a vlan tag on the packet (openflow.OFPAT_SET_VLAN_VID ), then output it to 
peth0(openflow.OFPAT_OUTPUT), but I can't capture the modified packet on peth0 
with wireshark, if I don't add the vlan tag, I can capture this kind packet as 
normal. Besides, I didn't configure the ovs's port to set a vlan tag(e.g. 
ovs-vsctl set port vnet0 tag=15), what's wrong? the NIC driver not support 
802.1q?  Thank you very much!
