Download the OpenShift Origin Version 3 VM image. The VM is over 2 GB in size. You can run the following command:

$ wget https://mirror.openshift.com/pub/origin-server/release/3/images/openshift-origin.zip –secure-protocol=SSLv3

Windows users can download either via the browser, or they can first download the wget software for Windows at http://gnuwin32.sourceforge.net/packages/wget.htm, and then use it to download the OpenShift Origin VM.

The advantage of using wget is that you can resume the partial download using the -c option. This will help if you are at a location where the Internet connection is not stable, so you can resume the download using the following command:

$ wget -c  https://mirror.openshift.com/pub/origin-server/release/3/images/openshift-origin.zip --secure-protocol=SSLv3

Next, unpack the zip archive using the 7-Zip file archiver:

$ 7z x openshift-origin.zip

Typing in this command will result in three additional files, as shown in the next command:

$ ls -1t

These are OpenShift Origin Release 3.vmx, OpenShift Origin Release 3.vbox, and origin-rel3.vmdk.

Start the VirtualBox manager, and click on the New button. Have a look at the following screenshot:
