There are two ways to implement OpenShift on your own hardware:
* The easiest way to run OpenShift locally is to [http://openshift.github.io/documentation/oo_deployment_guide_vm.html download an image] suitable for running on a VM. The image will work on KVM,VirtualBox or VMWare.
* You can also deploy OpenShift Origin manually.
**Note that this must be done on your host. Using these instructions on a VM results in an installation that works, but will not allow access to the GUI.
