Molecule libvirt Plugin

Molecule libvirt is designed to allow use of libvirt for provisioning test resources.

Please note that this driver is currently in its early stage of development, do not even try to install or use it until this message is removed.

Quickstart

Installation

pip install molecule-libvirt

Create a scenario

With a new role

  molecule init role -d libvirt my-role

This will create a new folder my-role containing a bare-bone generated role like you would do with ansible-galaxy init command.

It will also contain a molecule folder with a default scenario using the libvirt driver (using ansible community.libvirt collection).

Install the collection using:

ansible-galaxy install -r test_requirements.yml.

Optional parameters

molecule_bridge: existing bridge on local host. Can be useful if you want to set network interface name created for molecule. default value is: molecule-br0.

molecule_network_cidr: ip address range that should be bind to molecule virtual network. default value is: 10.10.10.0/24.

qemu_user: qemu process user. On RHEL like system qemu user is qemu. On Debian like, qemu user is libvirt-qemu. default value is: qemu.

cpu_model: specifies CPU model requested by the guest virtual machine. default is : qemu64.

arch: specifying the CPU architecture to virtualization. default is x86_64.

timezone: vm's timezone. default is America/Toronto.

bridge_name: existing bridge on remote host. This bridge should allow VM being reachable with an ip address.

libvirt_host and libvirt_user: remote host parameters. libvirt_user should belongs to libvirt group.

Once set, you will have to run:

molecule test
