OpenShiftのVagrantfileはParallelsには対応してないようだ

環境: OSX Yosemite, Parallels, Vagrant(v1.6.5)

Vagrantのparallelsプラグインはインストール済み。

OpenShiftを引っ張ってくる。

$ mkdir -p $GOPATH/src/github.com/openshift        
$ cd $GOPATH/src/github.com/openshift              
$ git clone git://github.com/openshift/origin
$ cd origin

Parallelsだとエラーが出る。

$ vagrant up --provider=parallels
Bringing machine 'openshiftdev' up with 'parallels' provider...
There are errors in the configuration of this machine. Please fix
the following errors and try again:

vm:
* A box must be specified.

Virtualboxだと大丈夫。

$ vagrant up --provider=virtualbox
Bringing machine 'openshiftdev' up with 'virtualbox' provider...
==> openshiftdev: Box 'fedora_inst' could not be found. Attempting to find and install...
(略)

Vagrantfileを見ると、それっぽい記述がある。
