\subsubsection{Create Keys}
\subsection{Create Keys}
Create (if needed) a public/private key pair and register it with OpenStack. If you do not have a key pair, generate one using
nova. (I prefer to name these with the OpenStack cluster/environment name, and then the key name with an extension that
indicates private key: agave.scooter.pk.)

\subsubsection{Start Tiny Boot-up VM}
Create and initialise a tiny VM that will act as the initial gateway to the virtual environment for processes running on the workstation.
\subsection{Start Boot-up VM}
Create and initialise a tiny\footnote{If you are going to need to create OS images during setup, use a meidum VM.}
VM that will act as the initial gateway to the virtual environment for processes running on the workstation.
For the examples used in the remainder of this document, the boot-up VM is given the name \verb!scooter_bv.!
The VM should be started with the key that was registered with OpenStack.
\small\begin{verbatim}
nova boot --image centos --flavor m1.tiny --key_name shared \
--security_groups default scooter_bv
}
\end{verbatim}\normalsize
\noindent
The VM should boot quickly and once it is active you may continue.
\subsubsection{Add A Floating IP Address}
\subsection{Create O/S Images}
If suitable inception cloud images are not already available in the current virtual environment, they must be created.
The following lists the steps necessary to create the O/S images:
\begin{enumerate}
\item Ssh to the boot-up VM.
\item Copy inception utility scripts from the source installed on the workstation.
\item Run the script \verb!pre_switch_kernel.sh! to convert from a vertual kernel to a generic kernel.
\item Wait for the VM to reboot and log in again.
\item Run the script \verb!pre_install_ovs.sh! to install open vswitch.
\item Using nova, or the dashboard, take a snapshot of the VM giving it an image name of XXX-gv.
\item Run the script \verb!pre_install_chefserver.sh! to install the Chef software.
\item Create another image naming it XXX-gvc.
\end{enumerate}
Image names (shown as XXX in the above list), can be anything that aligns with local policy and are used
with the \verb!--image! and \verb!--chefserver_image! options on the \verb!orcehestrator! command line.
\subsection{Add A Floating IP Address}
Add a floating (public) IP address to the new VM so that it can be reached from the "real world."

\subsubsection{Start sshuttle}
\subsection{Start sshuttle}
The sshuttle programme creates a tunnel through ssh allowing programmes on the workstation to access VMs created on the
same internal network as the boot-up VM without having to assign each VM a public address.
The sshuttle command is given the private key portion of the key pair that was used to start the boot-up VM; this is
