Driver vagrant does not provide a schema

[OGrigorios]

I am currently facing the issue of wanting to run molecule with vagrant+libvirt. I have verified that I can create virtual machines with vagrant+libvirt via vagrant-cli. This perhaps leads to the error of:

TASK [Gather system info] ******************************************************
fatal: [test-wg-debianbull]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: ssh: Could not resolve hostname test-wg-debianbull: Name or service not known", "
unreachable": true}

My molecule.yml:

---
dependency:
  name: galaxy
driver:
  name: vagrant
  provider:
    name: libvirt
    type: libvirt
    options:
      memory: 192
      cpus: 2
platforms:
  - name: test-debianbull
    box: debian/bullseye64
    interfaces:
      - auto_config: true
        network_name: private_network
        type: static
        ip: 192.168.10.10
provisioner:
  name: ansible
verifier:
  name: ansible

And my converge.yml

---
- name: Converge
  hosts: all
  become: true
  remote_user: vagrant
  tasks:
    - name: "Include g7s.unbound"
      ansible.builtin.include_role:
        name: "g7s.unbound"

And the output from molecule --version

❯ molecule --version
molecule 5.1.0 using python 3.11
    ansible:2.15.1
    azure:23.4.1 from molecule_plugins
    containers:23.4.1 from molecule_plugins requiring collections: ansible.posix>=1.3.0 community.docker>=1.9.1 containers.podman>=1.8.1
    delegated:5.1.0 from molecule
    docker:23.4.1 from molecule_plugins requiring collections: community.docker>=3.0.2 ansible.posix>=1.4.0
    ec2:23.4.1 from molecule_plugins
    gce:23.4.1 from molecule_plugins requiring collections: google.cloud>=1.0.2 community.crypto>=1.8.0
    podman:23.4.1 from molecule_plugins requiring collections: containers.podman>=1.7.0 ansible.posix>=1.3.0
    vagrant:23.4.1 from molecule_plugins

I would appreciate any indicators of what might be wrong here. There was a similar issue in 2017, but that did not help me.

I don't see libvirt among the Molecule modules, and it seems molecule-libvirt has been archived.

Can you run a verbose molecule test?

[OGrigorios]

Hm, that is true. But I am using libvirt through Vagrant, so I thought vagrant handles libvirt and molecule handels Vagrant. Maybe I am wrong in this assumption. The moleucle test:

The schema warning is just a warning. It could have been written at "info" severity level but it's better to have it as warning so that we don't forget to provide driver specific schema.

Looks like you're missing python-vagrant. Did you install it ?

[OGrigorios]

It wasn't installed... Ouch. It is running now. Thank you for your quick help, guys!
