Ansible modules extremely slow

Hello,

I'm using the Ansible module from the Collection to create a VM. It works, but compared to the openstack CLI it's very very slow. Ansible takes 4.5 mins versus few seconds with the CLI.

Check below with the CLI: 10 seconds, and I immediately see the VM, with the IP, in the control plane.

Here's with Ansible: 4.5 minutes!

$ ansible-playbook play.yml 
PLAY [PROVISION HOSTS AND BUILD ANSIBLE HOSTS INVENTORY] ***********************************************

TASK [openstack.cloud.server] **************************************************************************
2020-06-03 08:48:55 (0:00:00.017)       0:00:00.018 *************************** 
ok: [localhost]

TASK [debug] *******************************************************************************************
2020-06-03 08:53:23 (0:04:28.521)       0:04:28.540 ***************************

Below is the playbook:

---
- name: PROVISION HOSTS AND BUILD ANSIBLE HOSTS INVENTORY
  hosts: localhost
  connection: local
  gather_facts: no
  become: no
  tasks:       
    - openstack.cloud.server:
        name: fab-vm1
        state: present
        region_name: Fabnet
        availability_zone: STANDARD
        network: INTERNAL_NET
        image: "CentOS-7"
        key_name: fusion
        security_groups: default
        flavor: m5.xlarge
        auto_ip: no

      register: out

    - debug: var=out

I must be doing something very very wrong, but can't see it. any suggestion, please?

I would check the documentation. How does the Ansible module determine that the instance is "present"? Perhaps it waits until the instance is ACTIVE? Or until it can ssh into it?

after I start the play, I refresh the openstack control plane to see if my instance comes up. but it doesn't. It just takes ages to create the instance, let alone waiting for it to be ready
