Virtualize OSX on Linux

"I've been a Linux user for something like 10 years now. In order to develop and maintain psutil on different platforms I've been using the excellent VirtualBox. With it, during the years, I've been able to virtualize different versions of Windows, FreeBSD, OpenBSD, NetBSD and Solaris and implement and protract support for such platforms inside psutil. Without VirtualBox there really wouldn't exist psutil as it stands nowadays.

At some point I also managed to virtualize OSX by using an hacked version of OSX called iDeneb which is based on OSX 10.5 / Leopard (note: 9 years old), and that is what I've been using up until today. Of course such an old hacked version of OSX isn't nice to deal with. It ships Python 2.5, it kernel panicks, I had to reinstall it from scratch quite often.

I'm really not sure how I could  have been missing this for all this time, but it turns out emulating OSX on Linux really is as easy as executing a one-liner:
vagrant init AndrewDryga/vagrant-box-osx; vagrant up
And that really is it! I mean... you're literally good to go and start developing! That will create a Vagrant file, download a pre-configured OSX image via internet (10GB or something) and finally run it in VirtualBox. The whole package includes:

OSX 10.10.4 / Yosemite

XCode 6.4 + gcc

brew

Python 2.7

In a couple of hours I modified the original Vagrantfile a little and managed to mount a directory which is shared between the VM and the host (my laptop) and ended up with this Vagrantfile."
