现象是 neutron-linuxbridge-agent 不断重启，但是不生产日志文件，最后启动失败，坑了我2天，找到问题 "neutron-linuxbridge-agent: AttributeError: 'module' object has no attribute 'is_coroutine_function'"

找到/usr/lib/python2.7/site-packages/tenacity/init.py 里面找到这个代码注释掉。

如下：

以前是：

def wrap(f):

if asyncio and asyncio.iscoroutinefunction(f):

r = AsyncRetrying(*dargs, dkw)
elif tornado and tornado.gen.is_coroutine_function(f):
r = TornadoRetrying(*dargs, *dkw)
else:
r = Retrying(dargs, dkw)

return r.wraps(f)    return wrap

改变后：

def wrap(f):

if asyncio and asyncio.iscoroutinefunction(f):

r = AsyncRetrying(*dargs, **dkw)

#elif tornado and tornado.gen.is_coroutine_function(f):

r = TornadoRetrying(*dargs, **dkw)

else:            r = Retrying(*dargs, **dkw)        return r.wraps(f)    return wrap
