错误日志如下：
N版存在问题，其它版本不知道
解决方法(代码问题)：
/usr/lib/python2.7/site-packages/neutron/common/utils.py
在这个方法上(def load_class_by_alias_or_classname)面增加下面代码：
class_SilentDriverManager(driver.DriverManager): """The lamest of hacks to allow us to pass a kwarg to DriverManager parent. DriverManager doesn't accept the warn_on_missing_entrypoint param to pass to its parent on __init__ so we mirror the __init__ here and bypass the one in DriverManager in order to silence the warnings. TODO(kevinbenton): remove once Ia6f5f749fc2f73ca6091fa6d58506fddb058902a is released or we stop supporting loading by class path. """ def __init__(self, namespace, name): p = super(driver.DriverManager, self) #pylint: disable=bad-super-call p.__init__( namespace=namespace, names=[name], on_load_failure_callback=self._default_on_load_failure, warn_on_missing_entrypoint=False )
在修改下这个方法def load_class_by_alias_or_classname：
mgr =driver.DriverManager(namespace, name)
将上面代码改成下面
mgr = _SilentDriverManager(namespace, name)重启服务即可：
systemctl restart neutron-dhcp-agent.service neutron-metadata-agent.service
