SDB:Cloud OpenStack Quickstart
OpenStack installation from RPM packages on openSUSE
Packages for OpenStack are built under sub-projects of the OBS Cloud:OpenStack repository. See OpenStack and Crowbar development process for the workflow.
OpenStack Installation Guide for openSUSE and SUSE Linux Enterprise Server
The OpenStack documentation site contains an Installation Guide that covers installation and setup of OpenStack for openSUSE and SUSE Linux Enterprise Server. If you would like to setup OpenStack manually via RPM packages, this is a well documented route.
Automated deployment via SUSE Cloud
The easiest way to try out OpenStack on SUSE-based distributions is probably to use SUSE OpenStack Cloud which is an enterprise product based on SLES which uses Crowbar for automated deployment. You can download the evaluation version of SUSE OpenStack Cloud.
