Open Stack

Naveen try re-starting the whole suite  (devstack/unstack.sh followed by devstack/stack.sh) without any reboot.
I have noticed that there may be some race conditions and waits that do not wait long enough etc, so the system can come up in an inconsistent state.
:) Bugs that we shall have to harden against going forward.
Encountered a similar situation with keystone not coming up and consequently authentication failed when trying to use Horizon.
Hope it helps.

Subject: [openstack-dev] Run time error - Quantum OVS Agent

I am getting a run time error when starting up the ovs_quantum_agent. This setup was working before I rebooted the system . Any idea what the cause could be?. Looks like the agent has the wrong port ID.

#sudo python /usr/local/bin/ovs_quantum_agent.py  /etc/quantum/ovs_quantum_plugin.ini
kwargs = {'priority': 1, 'actions': 'normal'}
kwargs = {'in_port': '-1', 'delete': True}
Traceback (most recent call last):

Thanks a lot,
