##### Hi All,

I tried setting multiple group names using nova meta tag as below but couldn’t get that working using openstack.py dynamic inventory script for openstack. Can you please suggest?

[http://docs.ansible.com/ansible/intro\_dynamic\_inventory.html#example-openstack-external-inventory-script](http://docs.ansible.com/ansible/intro_dynamic_inventory.html#example-openstack-external-inventory-script)

```auto
$nova meta hostname set "group=mesos_masters"

$ansible -i inventory/openstack.py mesos_masters -m ping
b9d2e61e | SUCCESS => {
    "changed": false,
    "ping": "pong"
}

$nova meta hostname set "group=mesos_masters,consul_bootstrap"

$ansible -i inventory/openstack.py mesos_masters -m ping
 [WARNING]: provided hosts list is empty, only localhost is available

##### STEPS TO REPRODUCE
<!---
see above
-->

##### EXPECTED RESULTS
Should be able to run the playbook fetching the list of hosts

##### ACTUAL RESULTS
: provided hosts list is empty, only localhost is available
