libcloud.security.VERIFY_SSL_CERT = False

Openstack = get_driver(Provider.OPENSTACK)
openstack_ip="10.48.1.99"
con = Openstack(
'justuser', 'justpp',
ex_force_auth_url="http://{openstack_ip}:5000/".format(openstack_ip=openstack_ip),
ex_force_auth_version='2.0_password',
ex_tenant_name='harmonyqa',secure=False)
