Open Stack

HI Trinath,
just add the right credentials into your .bashrc or any file the system user can source : 

> export SERVICE_TOKEN=admin
>                                     
> export OS_TENANT_NAME=admin
> export OS_USERNAME=admin
> export OS_PASSWORD=openstack
> export OS_AUTH_URL=http://$keystone-IP:5000/v2.0/
> export SERVICE_ENDPOINT=http://$keystone-IP:35357/v2.0/
and it would work

Regards,
