from sqlalchemy import Column, Integer, String
from sqlalchemy.orm import exc
from quantum.db.models_v2 import model_base

class QoSPortBinding(model_base.BASEV2):
    __tablename__ = 'ovs_qos_port_binding'

    port_id = Column(String(20), primary_key=True)
    
    qos_id  = Column(String(20), primary_key=True)

    def __init__(self, port_id, qos_id):
        self.port_id = port_id
        self.qos_id  = qos_id

    def __repr__(self):
        return "<QoSPortBinding(%s, %s, %s)>" % (self.port_id, self.qos_id)

将代码置于/usr/share/pyshared/quantum/plugins/openvswitch# 中

2. 引入该模块

    在/usr/share/pyshared/quantum/plugins/openvswitch#下的ovs_db_v2.py中，导入上述模块 

from quantum.plugins.openvswitch import ovs_qos_db

3. 创建软连接

/usr/lib/python2.7/dist-packages/quantum/plugins/openvswitch#   ln -s ../../../../../../share/pyshared/quantum/plugins/openvswitch/ovs_qos_db.py  ovs_qos_db.py

4. 重启quantum-server

    service quantum-server restart
