I DO SEE the tag on VM profile when agent start, but I didn't see them on
OVS ports.

After this, vnet2 should be tagged with 1610, but:
root@yasker-box1:~# ovs-vsctl list port vnet2
_uuid : 012a6140-bd87-4917-84cc-7190829c695a
bond_downdelay : 0
bond_fake_iface : false
bond_mode : []
bond_updelay : 0
external_ids : {}
fake_bridge : false
interfaces : [95bcf67b-12c1-44e5-87da-5663c6644da3]
lacp : []
mac : []
name : "vnet2"
other_config : {}
qos : []
statistics : {}
status : {}
tag : []
trunks : []
vlan_mode : []
So it cannot access the public network.
After:
root@yasker-box1:~# ovs-vsctl set port vnet2 tag=1610
root@yasker-box1:~# ovs-vsctl list port vnet2
_uuid : 012a6140-bd87-4917-84cc-7190829c695a
bond_downdelay : 0
bond_fake_iface : false
bond_mode : []
bond_updelay : 0
external_ids : {}
fake_bridge : false

lacp : []
mac : []
name : "vnet2"
other_config : {}
qos : []
statistics : {}
status : {}
tag : 1610
trunks : []
vlan_mode : []
It can access the public network with vlan 1610.
