I’m trying to use the libvirt kvm terraform provider (https://github.com/dmacvicar/terraform-provider-libvirt) to connect an example virtual machine to an existing network bridge I’ve created. I’m using the simple example from here; https://github.com/fabianlee/terraform-libvirt-ubuntu-examples.git . Here’s the tf, the bridge details are below that; any suggestions would be gratefully received.
# variables that can be overriden
variable "hostname" { default = "simple" }
variable "domain" { default = "example.com" }
variable "memoryMB" { default = 1024*1 }
variable "cpu" { default = 1 }
# instance the provider
provider "libvirt" {
uri = "qemu:///system"
}
# fetch the latest ubuntu release image from their mirrors
resource "libvirt_volume" "os_image" {
name = "${var.hostname}-os_image"
pool = "default"
source = "https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img"
format = "qcow2"
}
# Use CloudInit ISO to add ssh-key to the instance
resource "libvirt_cloudinit_disk" "commoninit" {
name = "${var.hostname}-commoninit.iso"
pool = "default"
user_data = data.template_file.user_data.rendered
network_config = data.template_file.network_config.rendered
}
resource "libvirt_network" "vm_network" {
name = "test_net"
mode = "bridge"
bridge = "br0"
}
data "template_file" "user_data" {
template = file("${path.module}/cloud_init.cfg")
vars = {
hostname = var.hostname
fqdn = "${var.hostname}.${var.domain}"
}
}
data "template_file" "network_config" {
template = file("${path.module}/network_config_dhcp.cfg")
}
# Create the machine
resource "libvirt_domain" "domain-ubuntu" {
name = var.hostname
memory = var.memoryMB
vcpu = var.cpu
disk {
volume_id = libvirt_volume.os_image.id
}
network_interface {
network_name = "default"
}
cloudinit = libvirt_cloudinit_disk.commoninit.id
# IMPORTANT
# Ubuntu can hang is a isa-serial is not present at boot time.
# If you find your CPU 100% and never is available this is why
console {

# show IP, run 'terraform refresh' if not populated
