Description of Issue/Question

Terraform crashes while creating a virtual machine

Setup

Latest updated Fedora 27 (updated 6th Feb 2018)
Latest Terraform built from git
Latest terraform-provider-libvirt built from git

Terraform Plan

[root@laptop k801]# cat k801.tf
provider "libvirt" {
uri = "qemu:///system"
}

// blank 32GB image for net install.
resource "libvirt_volume" "k801-qcow2" {
name = "k801-qcow2"
pool = "default"
format = "qcow2"
size = 343597383680
}

// set boot order hd, network
resource "libvirt_domain" "k801-qcow2" {
name = "k801"
memory = "2048"
vcpu = 2

network_interface {
network_name = "dc00-10"
}
boot_device {
dev = [ "hd", "network"]
}
disk {
volume_id = "${libvirt_volume.k801-qcow2.id}"
}
graphics {
type = "spice"
autoport = "yes"
address = "0.0.0.0"
listen_type = "address"
}
}

Steps to Reproduce Issue

Latest updated Fedora 27 (updated 6th Feb 2018)
Latest Terraform built from git
Latest terraform-provider-libvirt built from git

---

Additional Infos:

Virtual machine is still created and installs as expected.

Appears Terraform simply time out after 30seconds and then crashes due to
panic: runtime error: invalid memory address or nil pointer dereference:

Shell session:

[root@laptop k801]# terraform apply -auto-approve

Initializing provider plugins...

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform.
A crash log has been placed at "crash.log" relative to your current
working directory. It would be immensely helpful if you could please
report the crash with Terraform1 so that we can fix this.

When reporting bugs, please include your terraform version. That
information is available on the first line of crash.log. You can also
get it by running 'terraform --version' on the command line.

!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

Perhaps my libvirt setup is incorrect. I'm using a separate dhcp service rather then the libvirt dhcp.

WIll change and re-test

Fixed!

I shutdown my dhcp service and configured the libvirt network's dhcp.... problem solved.
