So whilst trying to get boxen to work I needed a good method to test, so of course I turned to Vagrant and standing on the works of others (namely Graham Gilbert ) I used the following steps:

Requirements

Steps

Download and install packer, the easiest method to do this I found was using homebrew

$ brew install packer

Get the OSX template for packer

$ mkdir $HOME/tmp && cd $HOME/tmp
$ git clone https://github.com/timsutton/osx-vm-templates.git
Cloning into 'osx-vm-templates'...
remote: Reusing existing pack: 193, done.

Prepare packer to install Mavericks

$ cd $HOME/tmp/osx-vm-templates
$ sudo prepare_iso/prepare_iso.sh "/Applications/Install OS X Mavericks.app" out

This should result in :

$HOME/tmp/osx-vm-templates/out/OSX_InstallESD_10.9.2_13C64.dmg
-- Fixing permissions..
-- Checksumming output image..
-- MD5: dbe60cbeab09208e3ed20985975068b9
-- Done. Built image is located at out/OSX_InstallESD_10.9.2_13C64.dmg. Add this iso and its checksum to your template.

Then change packer/template.json to insert the DMG source and checksum

$ cd packer/ && packer build template.json

And once that has done it's thing you will end up with :

$ vagrant box add osx packer_vmware-iso_vmware.box
==> box: Adding box 'osx' (v0) for provider:
    box: Downloading: file://.../packer/packer_vmware-iso_vmware.box
==> box: Successfully added box 'osx' (v0) for 'vmware_desktop'!
