If you already have account on FutureGrid, you can use it with this steps.
ssh <username>@india.futuregrid.org
module load novaclient
source ~/.futuregrid/openstack_havana/novarc
If you belong to multiple projects, you can easily switch your tenant/project, with this.
source ~/.futuregrid/openstack_havana/<project_id>
Other than the initial setting, the rest of how-to is the same as our OpenStack Grizzly Manual.
