Thank you very much for the contribution! I don't have experience with other provider than virtualbox when using vagrant, how are we supposed to use parallels instead of virtualbox? Comment the virtualbox part and uncomment the paralles part?

[beardedeagle]

You can uncomment all of them all at once if you would like as calling with a specific provider will ignore the other provider directives, I just commented them out for this commit. You basically have to preconfigure your provider or call it during your vagrant up command like such:
vagrant up --provider=parallels

I have a work provided mac that comes with parallels so I usually use it over VirtualBox or VMWare since the integration into the mac desktop is superb. I have tested these configurations and they work. I will link the docs below if you would like to look though:

http://parallels.github.io/vagrant-parallels/docs/usage.html
https://docs.vagrantup.com/v2/vmware/usage.html

Will it works if the providers specific sections are commented?

[beardedeagle]

They would need to uncomment if they were using a provider other than VirtualBox before running the vagrant up command.

Do you need me to do anything else to get this merged?

[Lothiraldan]

Hi @beardedeagle, I wanted to try to play with multiple providers before merging, will do that right now.

I give it a try, I would prefer to have all providers uncommented as it isn't disturbing when we don't have parallels installed for example.

For the parallels custom vm box, we may use the override argument like that:

  # Parallels provider specifics
  config.vm.provider "parallels" do |prl, override|
   prl.memory = 1024
   prl.cpus = 2
   # Parallels specific Ubuntu 14.04 Vagrant box
   override.vm.box = "parallels/ubuntu-14.04"
  end

to use the ubuntu/trusty64 in all case except with parallels. With this modification I see no barrier to uncomment all providers blocks, maybe we just need to put a phrase in the README saying to users can use the --provider argument of vagrant to choose the one they want.

Could you give it a try with the override modification?

[beardedeagle]

yeah, I will get this done and updated asap.
