Hey there,

New to Packer but am very close to getting my first base box for vagrant working properly. I have a script that will ensure our developers are using VirtualBox 5.2.0. I downloaded the VBoxGuestAdditions.iso and am placing it via my builder. I tried moving it around and placing it in /tmp then using a bootstrap to move it to the proper location but it isn't working. Once my base box is created, running vagrant up produces the following error:

[default] GuestAdditions versions on your host (5.2.0) and guest (5.0.18) do not match.

As we want to keep our hosts 5.2.0, I need to have my base box created with 5.2.0. Here is my current builder:

"builders": [

{

"type": "virtualbox-iso",

"guest_os_type": "Ubuntu_64",

"guest_additions_url": "./VBoxGuestAdditions.iso",

"iso_url": "http://releases.ubuntu.com/16.04.3/ubuntu-16.04.3-server-amd64.iso",

"iso_checksum": "f3532991e031cae75bcf5e695afb844dd278fff9",

"iso_checksum_type": "sha1",

"vm_name": "packer-ubuntu-16.04-amd64",

"disk_size": "{{ user `disk_size` }}",

"headless": "{{ user `headless` }}",

"boot_wait": "5s",

"http_directory": "http",

"boot_command": [

"<enter><wait>",

"<f6><esc>",

"<bs><bs><bs><bs><bs><bs><bs><bs><bs><bs>",

"<bs><bs><bs>",

"/install/vmlinuz ",

"initrd=/install/initrd.gz ",

"auto=true ",

"priority=critical ",

"net.ifnames=0 ",

"url=http://{{ .HTTPIP }}:{{ .HTTPPort }}/preseed.cfg",

"<wait><enter>"

"ssh_wait_timeout": "30m",

"ssh_username": "ubuntu",

"ssh_password": "ubuntu",

"shutdown_command": "sudo systemctl poweroff",

"vboxmanage": [

["modifyvm", "{{ .Name }}", "--memory", "{{ user `memory` }}"],

["modifyvm", "{{ .Name }}", "--cpus", "{{ user `cpus` }}"]

]

}

The guest_additions_url is the download straight from virtualbox.org for 5.2.0. When Packer is building my image, I see the following info messages so not sure why it gets downgraded to 5.0.18:

==> virtualbox-iso: Downloading or copying Guest additions checksums

virtualbox-iso: Downloading or copying: http://download.virtualbox.org/virtualbox/5.2.0/SHA256SUMS

==> virtualbox-iso: Downloading or copying Guest additions

virtualbox-iso: Downloading or copying: file:///Users/matt.denton/config_management/puppet/packer/VBoxGuestAdditions.iso

==> virtualbox-iso: Uploading VirtualBox version info (5.2.0)

==> virtualbox-iso: Uploading VirtualBox guest additions ISO...

Getting into my base box via vagrant up (and taking the time to update the guest additions via vagrant-vbguest plugin) I see the following broken symlink:

lrwxrwxrwx 1 root root 52 Oct 29 14:35 VBoxGuestAdditions -> /opt/VBoxGuestAdditions-5.2.0/lib/VBoxGuestAdditions

If I change the symlink to point /usr/lib/VboxGuestAdditions to the same .iso I have in my builder, it all works. Really been beating my head against the wall and any assistance on this would be appreciated. Thanks!

Hello

packer will do something with the additions iso, like copy it to the home user of the ssh user, or mount it in the dvd or do nothing.

From here you need to have a provisioning step to make the installation

something like this:

https://github.com/cbednarski/packer-ubuntu/blob/master/scripts-1604/virtualbox.sh

I don't see the provisioning part on your template, so not sure if you are installing it or not.

The message you see is just a note, not an error:

[default] GuestAdditions versions on your host (5.2.0) and guest (5.0.18) do not match.

Can you share your scripts and packer template in a github repo ?

Alvaro.
