I did that...and I suppose this is the problem: I mean there are some dependancies problems this is what I did wget https://launchpad.net/quantum/folsom/2012.2/+download/quantum-2012.2.tar.gz (https://launchpad.net/quantum/folsom/...) tar xf quantum-2012.2.tar.gz cd quantum-2012.2/tools pip-python install -r pip-requires cd .. sed -i 's/quantum-l3-agent = quantum.agent.l3_nat_agent:main/quantum-l3-agent = quantum.agent.l3_agent:main/g' setup.py sed -i '128a \tif self.conf.use_namespaces:' quantum/agent/l3_agent.py sed -i 's/ self._destroy_all_router_namespaces()/\t\ \ \ \ self._destroy_all_router_namespaces()/g' quantum/agent/l3_agent.py sed -i 's/def wait(self, check_interval=0.01):/def wait(self, check_interval=0.01,timeout=None):/g' /usr/lib/python2.6/site-packages/eventlet/green/subprocess.py python setup.py install

I need to rollback everything bu I don't know how

I fixed the problem by reinstalling all the dependencies with easy_install and not with pip. But unfortunately when I start the ovs agent, I get this issue:

Yes I'm using CentOs 6.3. I checked the file and the timeout parameter is already there. This is the error traceback
