why tag are created when booting vm

     Hi Team

    I'm using Openstack Newton all in one node setup using devstack on ubuntu using ml2 plugin.Whenever I'm booting Vm,the virtual interface is getting associated with vlan tag.Below is the output of ovs-vsctl show ..

           Interface patch-tun
                    type: patch
                    options: {peer=patch-int}
            Port "ni0"
                Interface "ni0"
            Port "qvo6661eb1a-fb"
                Interface "qvo6661eb1a-fb"
            Port "veth1"
                Interface "veth1"
            Port br-int
                Interface br-int
                    type: internal
            Port "qvo8c9b170b-57"
                Interface "qvo8c9b170b-57"
                tag:1
            Port "qvo07afd92c-55"
                Interface "qvo07afd92c-55"
                tag:2
        ovs_version: "2.4.1"

I want to know the actual reason for this functionality.

Thanks
