This will make it easier to move into the existing infra step. The module source syntax used in the README is documented in [1,2,3], and means "the modules/libvirt/bootstrap subdirectory of the github.com/openshift/installer repository cloned over HTTPS".

Bootstrap Module
This Terraform module manages libvirt resources only needed during cluster bootstrapping. It uses implicit provider inheritance to access the libvirt provider.
Example
Set up a main.tf with:
provider "libvirt" {
uri = "qemu:///system"
}
resource "libvirt_network" "example" {
name = "example"
mode = "none"
domain = "example.com"
addresses = ["192.168.0.0/24"]
}
resource "libvirt_volume" "example" {
name = "example"
source = "file:///path/to/example.qcow2"
}
module "bootstrap" {
source = "github.com/openshift/installer//modules/libvirt/bootstrap"
addresses = ["192.168.0.1"]
base_volume_id = "${libvirt_volume.example.id}"
cluster_name = "my-cluster"
ignition = "{\"ignition\": {\"version\": \"2.2.0\"}}",
network_id = "${libvirt_network.example.id}"
}
Then run:
$ terraform init
$ terraform plan
