Comment 0 for bug 1549074

This is 3 Node Liberty setup (controller, Network and Compute) configured with neutron Network option 2 : Self servicing network and is with openvswitch.
I found everything is working fine except while launching instance I'm getting error as follows , By tracing keystone.log and nova-api.log and based on time stamp I see Keystone fails the authentication followed by nova-api started throwing the exception errors.

Attached the config files and logs for you reference ... Request you to help me ASAP.

Thank You
