How to build libvirt box from scratch

Question

I'm trying to build vagrant libvirt box from scratch.

I insttalled ubuntu 14.04 and used this tutorial to prepare machine for vagrant using and then I used command virsh domblklist test to find my image file, so i find it here /var/lib/libvirt/images/test.img and then copied to place where I'm going to package my vagrant box. Then I converted my raw image file to qcow2 format (beacause this page says that only qcow2 format supported) with sudo qemu-img convert -f raw -O qcow2 test.img test.qcow2 command. Finally to get things done I executed vagrant init test and created metadata.json file with this in it

{
  "provider"     : "libvirt",
  "format"       : "qcow2",
  "virtual_size" : 8
}

And then I used command tar cvzf vltest.box ./metadata.json ./Vagrantfile ./box.img to get things together in one box. Then I added box to vagrant with vagrant box add test.img test.

Then I tried to run machine with

vagrant init test
vagrant up --provider=libvirt

But it stuck here:

...
==> default:  -- Video VRAM:        9216
==> default:  -- Keymap:            en-us
==> default:  -- INPUT:             type=mouse, bus=ps2
==> default:  -- Command line : 
==> default: Creating shared folders metadata...
==> default: Starting domain.
==> default: Waiting for domain to get an IP address...

Then I decided to open machine and that was what I saw:

Here is origin machine configurations:

Update: Also I tried packer but get the same error, when grub shows up. Here is my template for packer:

{
    "builders":
    [
      {
        "type": "qemu",
        "iso_url": "/home/galiaf95/Downloads/ubuntu-14.04.3-desktop-amd64.iso",

        "disk_interface": "virtio"
      }
    ],
    "post-processors": [
        {
            "keep_input_artifact": false,
            "output": "box/ubuntu-1404-server.box",
            "type": "vagrant"
        }
    ]
}

ISO file of ubuntu 14.04 I downloaded from ubuntu site.

So my questions are:

1. What I did wrong and how to solve that
2. Is there more proper way of building vagrant libvirt boxes from scratch

Answer 1

What I did wrong and how to solve that

can't really help from my side

Is there more proper way of building vagrant libvirt boxes from scratch

I would recommend using packer as from [v 0.7.2]( https://www.polibyte.com/blog/packer_supports_vagrant-libvirt) packer supports for vagrant-libvirt
