Description of Issue/Question

Setup

terraform {
  required_version = ">= 0.13"
    required_providers {
      libvirt = {
        source  = "dmacvicar/libvirt"
        version = "0.6.11"
      }
    }
}

Steps to Reproduce Issue

After Guest Agent connect on libvirt host I use: virsh qemu-agent-command dhcp-test-00 '{"execute": "guest-network-get-interfaces"}' --pretty Return:

.....
{
      "name": "ens3",
      "ip-addresses": [

        },
        {
          "ip-address-type": "ipv6",
          "ip-address": "fe80::5054:ff:fe7e:ec72",

if run TF_LOG=DEBUG terraform refresh return:
