Terraform Modules for libvirt provider

This repository contains terraform modules to quickly create libvirt VMs from cloud images using Terraform with libvirt provider.

test Terraform-Version libvirt-Version license

Requirements

  • KVM supported Linux Machine
  • libvirtd is up and running
  • Terraform.

Usage

  • modules/net - Creates a Network

    module "vnet" {
  source = "git::https://github.com/tprasadtp/tfm-libvirt.git//modules/net"
  name   = "test"
  domain = "test.kvm"
  subnet = "192.168.127.0/24"
}

  • modules/vm - Creates VM

    module "vm" {
  source            = "git::https://github.com/tprasadtp/tfm-libvirt.git//modules/vm"
  cloudimage        = pathexpand("~/Virtual/installers/focal-server-cloudimg-amd64.img")
  cloudimage_format = "raw"
  name              = "test"
  network           = "test"
  vcpu              = 1
  memory            = 256
  vcpu_model_host   = true
  user_data         = file("${path.module}/user-data.cfg")
}

Notes

  • This module is meant to quickly create headless machines in a reproducible way.
  • VMs with UI are NOT supported!, vm module even strips off all video/spice devices!
  • Advanced configs are not supported. You might look into provider's documentation for creating VMs which support additional features.

Tests

  • Tests spin up VMs and asserts they are running with right config using ansible.
  • You can use already installed version of ansible if you wish. Otherwise, poetry install

Cloud images

VMs use cloud images as its easier to configure them them using cloud-init.

Supported Guest OS
