[openstack-dev] FW: how to configure cisco plugin in devstack environment

Hi Yuling -

Here are instructions I found on installing configobj: http://www.voidspace.org.uk/python/articles/configobj.shtml

Also, you didn't get the latest (master) cisco quantum code.
In localrc please add/change:
OFFLINE=False
RECLONE=yes

Also, are you using a nexus hardware switch in your topology?

Thanks,
Rich

Thanks very much for the information... I just tried commenting out #QUANTUM_BRANCH=stable/grizzly. However, when I ran 'stack.sh' again, I still hit the same issue.

>From reading the log, I can see quantum was trying to pick up cisco plugin. However, it failed at importing configobj at cisco_configparser.py. Could this be PYTHONPATH issue? (However, I don't see any instructions for changing this environment variable)

When you mentioned that

Do I need to pick up this change as well? The only thing I picked up was Robert's file of lib/quantum_plugins/cisco...the rest running on my environment was devstack grizzly release...


Thanks,

YuLing
