Any interest to create box with 2 hdd?

[rubisher]

Describe the Enhancement

Looking to create a custom vagrant box with 2 hdd.

Describe the Need

To be able to create an Ansible lab with VM like in our prod ;)

Current Alternative

The alternate stand in a cutom vboxmanage var like:

vboxmanage = [
    [
      "createmedium", "disk",
      "--format", "VDI",
      "--filename", "disk_02.vdi",
      "--size", "69632",
    ],
    [
      "storageattach", "{{.Name}}",
      "--storagectl", "SATA Controller",
      "--port", "1", "--type", "hdd",
      "--medium", "disk_02.vdi",
    ]
  ] 

but 'packer' is able to manage more efficiently (imho)?

Can We Help You Implement This

I just have to add a new var definition like:

$ diff -Nau ./packer_templates/pkr-variables.pkr.hcl.orig ./packer_templates/pkr-variables.pkr.hcl

 variable "vbox_hard_drive_interface" {

to be able to add it to the 'source "virtualbox-iso" "vm" ' like:

and also add its requirement in a custome os_pkrvars/centos/rudy-centos-7-x86_64.pkrvars.hcl:
vbox_disk_additional_size = [ 69632 ]

After a quick run, it seems that the box contains well the 2 virtual disks I wanted:

$ tar -tlpvf ./packer_templates/../builds/centos-7.9-x86_64.virtualbox.box

-rw-r--r-- jlst/sysadmins        26 2023-08-13 10:09 metadata.json

PS: I think that we would need different var for each type of VM tool (not sure but qm would need a list(string)?)

Take care,
Rudy

Adding the feature doesn't hurt anything so I'm open to PR's to help implement. We won't be modifying the default OS templates and publishing them with multiple drives to the bento vagrant hub account though. Those boxes are meant to be simple install for temporary testing purposes.
