Parallels vm.provider creating duplicate disks when using --device-add

[lonedevel]

I'm trying to create multi-node environment for distributed database testing. The database can run on multiple VMs and I'm trying to configure each with a separate separate disk and mount point for the database content.

In my Vagrantfile I'm only calling the provider.customize option once, yet I see 2 new SATA hdd definitions in each VM configuration that have the same size (128GB). I attached debug output log from the vagrant up command.

Here is the Vagrantfile:

Vagrant.configure("2") do |config|
  config.vm.box = "bento/ubuntu-18.04"
  config.vm.provider "parallels" do |prl|
    prl.update_guest_tools = true
    prl.memory = "8192"
    prl.customize ["set", :id, "--device-add", "hdd", "--size", "128G"]
  end
  (1..3).each do |i|
    node_num = i.to_s.rjust(2, '0')
    node_name = "mynode-#{node_num}"
    config.vm.define "#{node_name}" do |node|
      node.vm.hostname = "#{node_name}"
      node.vm.provider "parallels" do |prl|
        prl.name = "#{node_name}"
      end
      node.vm.provision "shell", inline: <<-SHELL
        apt-get update -y
        SHELL
      end
   end
end

Here is the VM Configuration.

Grepping the debug.log for the specific prlctl command yields:

Hi @lonedevel ,

Sorry for a late reply. The disk is added twice because the VM is getting rebooted during the initial vagrant up run (due to prl.update_guest_tools = true) and you have a configuration which makes prl.customize command to run on every boot:

    prl.customize ["set", :id, "--device-add", "hdd", "--size", "128G"]

^ This is a default behavior. In your case you definitely need to run it only once, after the VM is created, so please add "post-import" to that line :

    prl.customize "post-import" ["set", :id, "--device-add", "hdd", "--size", "128G"]

See more details in docs: https://parallels.github.io/vagrant-parallels/docs/configuration.html

Thank you @legal90! Much appreciated!
