数据库相应操作已完成，对OVS-Plugin进行修改。
在quantumpluginsopenvswitchovs_quantum_plugin.py中
使OVSQuantumPluginV2继承于上一篇所写的数据库操作类QuanlityOfServiceDbMixin。
- class OVSQuantumPluginV2(db_base_plugin_v2.QuantumDbPluginV2,
- ovs_qos_db.QualityOfServiceDbMixin,
- l3_db.L3_NAT_db_mixin):
在OVSQuantumPluginV2中，将相应的服务请求转到db类中去处理
- def get_ovsqoss(self, context, filters=None, fields=None):
- qoss = super(OVSQuantumPluginV2, self).get_ovsqoss(context, filters, fields)
- return qoss
- def get_ovsqos(self, context, id, fields=None):
- qos = super(OVSQuantumPluginV2, self).get_ovsqos(context, id, fields)
- return qos
- def delete_ovsqos(self, context, id):
- result = super(OVSQuantumPluginV2, self).delete_ovsqos(context, id)
- return result
- def update_ovsqos(self, context, id, ovsqos):
- result = super(OVSQuantumPluginV2, self).update_ovsqos(context, id, ovsqos)
- return result
- def create_ovsqos(self, context, ovsqos):
- qos = super(OVSQuantumPluginV2, self).create_ovsqos(context, ovsqos)
- return qos
