[!NOTE] This project is maintained on a best effort basis. I am not actively working on it.

From time to time I go over interesting PRs and do minor improvements.

New features are, by default not welcomed or accepted unless discussed and agreed upon.

If you are willing to contribute, this is what the project accepts as contributions:

  • maintainers, who take over an area and actively keep the code in good shape
  • improvements to testing, including enabling the acceptance testsuite in CI
  • modernizing the codebase and removing exceptions from the linters
  • writing v2, simplified versions of the resources

Terraform provider for libvirt

alpha Tests Registry

This is a terraform provider that lets you provision servers on a libvirt host via Terraform.

Introduction & Goals

This project exists:

What is NOT in scope:

Getting started

The provider is available for auto-installation from the Terraform Registry.

In your main.tf file, specify the version you want to use:

terraform {
  required_providers {
    libvirt = {
      source = "dmacvicar/libvirt"
    }
  }
}

provider "libvirt" {
  # Configuration options
}

And now run terraform init:

$ terraform init

Creating your first virtual machine

Here is an example that will setup the following:

(create this as main.tf and run terraform commands from this directory):

provider "libvirt" {
  uri = "qemu:///system"
}

You can also set the URI in the LIBVIRT_DEFAULT_URI environment variable.

Now, define a libvirt domain:

resource "libvirt_domain" "terraform_test" {
  name = "terraform_test"
}

Now you can see the plan, apply it, and then destroy the infrastructure:

$ terraform init
$ terraform plan
$ terraform apply
$ terraform destroy

Look at more advanced examples here and check the documentation.

Manual installation

You can also manually download the provider from the releases section on Github. To install it, refer to the Terraform documentation.

Building from source

git clone https://github.com/dmacvicar/terraform-provider-libvirt.git
cd terraform-provider-libvirt
make

The binary will be called terraform-provider-libvirt.

Using multiple hypervisors / provider instances

You can target different libvirt hosts instantiating the provider multiple times. Example.

Using qemu-agent

From its documentation, qemu-agent:

It is a daemon program running inside the domain which is supposed to help management applications with executing functions which need assistance of the guest OS.

Until terraform-provider-libvirt 0.4.2, qemu-agent was used by default to get network configuration. However, if qemu-agent is not running, this creates a delay until connecting to it times-out.

In current versions, we default to not to attempt connecting to it, and attempting to retrieve network interface information from the agent needs to be enabled explicitly with qemu_agent = true, further details here. Note that you still need to make sure the agent is running in the OS, and that is unrelated to this option.

Note: when using bridge network configurations you need to enable the qemu_agent = true. otherwise you will not retrieve the ip addresses of domains.

Be aware that this variables may be subject to change again in future versions.
