Vagrant with extra disks

Vagrantfile

Vagrant.configure("2") do |config|

  config.vm.box = "trusty"
  config.vm.box_url = "https://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box"

  config.vm.hostname = "devstack"

  # forward ssh keys from main host - handy for gerrit and github
  config.ssh.forward_agent = true

  # eth1 will be the primary interface for access to the vagrant box.
  # It's plugged into a virtualbox bridge, so its IP can be accessed
  # directly from the main host without nat port-forwarding hassle.
  # You can configure devstack so OpenStack services listen on this
  # address by putting HOST_IP=192.168.2.2 in localrc
  config.vm.network :private_network, ip: "192.168.2.2"

  # Add eth2 and eth3 - these can be used by Neutron or nova-network
  # It's necessary to specify IPs here - but they won't be configured.
  config.vm.network :private_network, ip: "192.168.3.2", auto_config: false
  config.vm.network :private_network, ip: "192.168.4.2", auto_config: false

  config.vm.provider "virtualbox" do |v|
    v.customize ["modifyvm", :id, "--cpus", "4"]
    v.customize ["modifyvm", :id, "--memory", "6000"]
    # enable serial port just in case vagrant image does not
    v.customize ["modifyvm", :id, "--uart1", "0x3F8", 4]

    file_to_disk = 'disk2.vdi'
    unless File.exist?(file_to_disk)
      # 50 GB
      v.customize ['createhd', '--filename', file_to_disk, '--size', 50 * 1024]
    end
    v.customize ['storageattach', :id, '--storagectl', 'SATAController', '--port', 1, '--device', 0, '--type', 'hdd', '--medium', file_to_disk]

    file_to_disk = 'disk3.vdi'
    unless File.exist?(file_to_disk)
      # 50 GB
      v.customize ['createhd', '--filename', file_to_disk, '--size', 50 * 1024]
    end
    v.customize ['storageattach', :id, '--storagectl', 'SATAController', '--port', 2, '--device', 0, '--type', 'hdd', '--medium', file_to_disk]

  end

end

is it possible to do that via vmdk type disk? does that applies to it too?

donno, haven't used vagrant in years - this gist is from 2014
