Rocky9 and Rocky10 generic cloud images hang when building with Terraform

Rocky Linux Help & Support

I am trying to build test servers using Terraform on KVM. It works if I use:

source = “https://download.rockylinux.org/pub/rocky/8/images/x86_64/Rocky-8-GenericCloud-LVM.latest.x86_64.qcow2”

But hangs if I change this to R9 or R10 images?

The other issue I have is if I try to create a fixed-IP it is ignored and I still get a DHCP address?

data "template_file" "network_config" {
  template = file("${path.module}/network.cfg")
}

# cat network.cfg

version: 2
ethernets:
  ens3:
    dhcp4: false
    dhcp6: false
     addresses:
       - 10.21.184.199
    gateway4: 10.21.184.1

I also tried via the cloud_init.cfg:

 cat cloud_init.cfg

#cloud-config

..

network:
version: 2
ethernets:
ens3:
dhcp4: no

gateway4: 10.21.184.1
nameservers:

Does anyone know why Terraform doesn’t work with Rocky9 and 10, and has anyone managed to create a VM with a fixed-IP?

I have created a main.tf that works for Rocky-10 but not 9?

cat main.tf

resource “libvirt_volume” “qcow_volume” {
name   = “${var.vm_name}.qcow2”
pool   = “default”
#source = “https://download.rockylinux.org/pub/rocky/9/images/x86_64/Rocky-9-GenericCloud-LVM.latest.x86_64.qcow2”
source = “https://download.rockylinux.org/pub/rocky/10/images/x86_64/Rocky-10-GenericCloud-LVM.latest.x86_64.qcow2”

format = “qcow2”
}

data “template_file” “user_data” {
template = file(“${path.module}/cloud_init.cfg”)

vars = {
hostname = var.host_name
domain   = var.domain
}
}

data “template_file” “network_config” {
template = file(“${path.module}/network.cfg”)
}

resource “libvirt_cloudinit_disk” “commoninit” {
name = “commoninit.iso”
pool           = “default”
user_data      = data.template_file.user_data.rendered
network_config = data.template_file.network_config.rendered

}

Define KVM domain to create

resource “libvirt_domain” “default” {
name       = var.vm_name
memory     = var.memory
vcpu       = var.cpu
qemu_agent = true

cloudinit = libvirt_cloudinit_disk.commoninit.id

#machine = “q35”
cpu {
mode = “host-passthrough”
}

disk {
volume_id = libvirt_volume.qcow_volume.id
}

console {
type        = “pty”
target_type = “serial”
target_port = “0”
}

graphics {
type        = “vnc”
listen_type = “address”
autoport    = true
}

network_interface {
network_name = “default”
addresses    = [var.ip_address]
hostname     = “${var.host_name}.${var.domain}”
wait_for_lease = false
}

connection {
type        = “ssh”
user        = var.ssh_username
host        = libvirt_domain.domain-.var.vm_name.network_interface[0].addresses[0]
private_key = file(var.ssh_private_key)
timeout     = “2m”
}
}

The biggest problem is creating a cloud_init.cfg and network.cfg as Rocky8, 9, and 10 all treat them differently.

Any ideas how I can get this working for Rocky-9 as 8 is too old and 10 is a bit unstable at present.

network.cfg:

cat network.cfg
