Openstack unable to assign ip to Instance

I am using os_server anisble module to spinup an instance. I am able to spinup instance and attach ip to it but after creating the instance I have to manually configure the ip. How can I make it assign the Ip automatically to instance while creating. Here is my module - name: Deploy on OpenStack hosts: localhost gather_facts: false tasks: - name : Create a new instance os_server: state: present auth: auth_url: http://xx.xxx.xx.xx:x000/v2.0 username: automation password: automation project_name: Automation name: test image: rhel-guest-image-7.2 key_name: ansible timeout: 200 flavor: ucc.as auto_floating_ip: yes nics: - net-name: corenet - net-name: nmnet - net-name: public meta: hostname: test1 On the openstack dashboard I can see the ip assigned to the instance but when I open the console on login the instance ip are not present. I have to manually configure it.
