This seems to be the part in nova/wsgi.py :

eventlet.patcher.monkey_patch(all=False, socket=True)

which patch the socket implementation with a greenlet which in this case using the twisted implementation and try to start the reactor but has been started already somewhere in Nova...

Is there a need for having socket eventlet'et?

 I have upgraded the eventlet library to latest version and this seems to work now... Sorry about the nosie :)
