Step 1) Pls open http://paste.openstack.org/show/802767/
Step 2) Observe the error log
Step 3) As per the explanation by 1 of the expert at
#openstack-ansible IRC channel, the error is due to connectivity issue
after executing following command = # scripts/bootstrap-ansible.sh

I guess the issue is for users connecting from India.
Do we have any users from India who can try the bootstrap command?
We just need to validate if bootstrap drops/stops/breaks connectivity
at 1 point.
I guess bootstrap copies those files under /etc/openstack_deploy/ & if
bootstrap itself fails, we wont see those files under /etc/ right?
