I upgraded to Parallels 12 Pro on my Mac because it says it supports Vagrant. I installed vagrant and VirtualBox like the instructions said but it gave me an error saying I needed VT-x. So I instead tried Vagrant-Parallels. Here is what I tried. vagrant plugin install vagrant-parallels vagrant add box parallels/ubuntu-14.04 mkdir vagranttest cd vagranttest vagrant init parallels/ubuntu-14.04vagrant vagrant box list (returns parallels/ubuntu-14.04 (parallels, 2.0.4)) vagrant up --provider=parallels (error: "The provider 'parallels' that was requested to back the machine 'default' is reporting that it isn't usable on this system. The reason is shown below: Parallels provider works only on OS X (Mac OS X) systems.' vagrant up (default: Box Provider: virtualbox)(Erorrs because box does not support virtual box as provider.) Any thoughts? Thanks.
