The phenomenon is that neutron-linuxbridge-agent constantly restarts, but does not produce log files, finally failed to start, pit me for 2 days, find the problem "Neutron-linuxbridge-agent:attributeerror: ' module ' object has no attribute ' is_coroutine_function ' "
Locate the/usr/lib/python2.7/site-packages/tenacity/init. PY and find this code commented out.
As follows:
Used to be:
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
After the change:
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
OpenStack Queens version of Linux Bridge does not come up with a workaround
