-\section{Getting the stuffs used for building guest image}
+\section{Getting the guest image build tools}
+
+In order to build the bootable guest ISO image, we need to build a Linux kernel
+ from source and an initial ramdisk file system containing a set of useful
+tools. We will use a new directory for demonstration; the root directory for the
+following examples is ``\verb+test/+":
-In order to build the bootable guest iso image, we need to build Linux kernel image from its source,
-an initial file system containing a set of useful binary files and other necessary directories and files,
-which will be specified in the following text.
+\begin{verbatim}
+[jdoe@newskysaw ~]$ mkdir test/
+\end{verbatim}
-We will use a new directory for demonstration,
-the root directory for our following examples are all in the \verb+test/+ as root directory.
+\noindent
+There are a set of tools and sources that are useful for the guest image
+building procedure. You can obtain these resources from our git repositories.
+Change to the ``\verb+test/+" directory and clone the resources:
\begin{verbatim}
-mkdir test/
-cd test/
+[jdoe@newskysaw test]$ git clone http://hornet.cs.northwestern.edu:9005/busybox
+[jdoe@newskysaw test]$ git clone http://hornet.cs.northwestern.edu:9005/initrd
+[jdoe@newskysaw test]$ git clone http://hornet.cs.northwestern.edu:9005/linux-2.6.30.y
\end{verbatim}
-There are a set of tools and sources that are useful for this building procedure. You can checkout these resources from our git repositories. To checkout them to your local directory, using commands:
+\section{Building the ramdisk filesystem}
+The guest requires an initial ramdisk filesystem. Jack has made one that you can
+leverage; it is temporarily located in his home directory. You will need sudo
+or root access to create the device files when you unpack the archive:
\begin{verbatim}
-git clone http://hornet.cs.northwestern.edu:9005/busybox
-git clone http://hornet.cs.northwestern.edu:9005/initrd
-git clone http://hornet.cs.northwestern.edu:9005/linux-2.6.30.y
+[jdoe@newskysaw test]$ cp /home/jarusl/initrd/disks/v3vee_initramfs.tar.gz .
+[jdoe@newskysaw test]$ sudo tar -C initrd -xzf v3vee_initramfs.tar.gz
\end{verbatim}
-\section{Build the ramdisk filesystem}
+\noindent
+If you require a custom initial ramdisk filesystem, change to the
+``\verb|initrd/initramfs/|" directory and perform the following steps:
-Copy needed devices into the \verb+initramfs/dev/+ directory,
-for minimal support, you need console, ram, null, tty.
-(You probably need root privilege to copy and make the device files)
+\begin{verbatim}
+[jdoe@newskysaw initramfs]$ mkdir -p proc sys var/log
+\end{verbatim}
-There is an already costumed initial ramdisk system made
-by Jack which you can leverage. The file is temporarily
-in \verb|/home/jarusl/initrd/disks/v3vee_initramfs.tar.gz|
-in newskysaw machine.
+\noindent
+Edit the ``\verb|init_task|" script and uncomment these lines:
-\section{Configure and Install Busybox tools}
+\begin{verbatim}
+#mknod /dev/tty0 c 4 0
+#mknod /dev/tty1 c 4 1
+#mknod /dev/tty2 c 4 2
+\end{verbatim}
-BusyBox is a software application released as Free software
-under the GNU GPL that provides many standard Unix tools. BusyBox
-combines tiny versions of many common UNIX utilities into a single
-small executable. For more details on Busybox, visiting http://busybox.net.
+\pagebreak
-To configure BusyBox, in the \verb+busybox/+ directory, type
+\noindent
+Create the ``\verb|console|" device. If you have sudo or root access it is
+possible to create this device manually:
\begin{verbatim}
-make meunconfig
-make xconfig (X version)
+[jdoe@newskysaw initramfs]$ sudo mknod dev/console c 5 1
+[jdoe@newskysaw initramfs]$ sudo chmod 0600 dev/console
\end{verbatim}
-You can add tools as you needed into the guest image. There are
-two specified configurations are required here:
-First, in the "\verb|Build Options|", check the option
-"\verb|Build BusyBox as a static binary (no shared libs)|",
-as shown in figure \ref{fig:busyboxcf1}. Second,
-in the "\verb|Installation Options|", Change
-the "\verb|Busybox installation prefix|" to be the path
-of your "\verb|initramfs|" directory, as shown in figure \ref{fig:busyboxcf2}.
-
-\begin{figure}\begin{center}\colfigsize\epsffile{busyboxConf1.eps}\end{center}\caption{BusyBox configuartion}\label{fig:busyboxcf1}\end{figure}
+\noindent
+If you do not have sudo or root access it is still possible to create the
+``\verb|console|" device indirectly through the kernel build. Change to the
+``\verb|initrd/|" directory and create a file called ``\verb|root_files|". Add
+the following line:
-\begin{figure}\begin{center}\colfigsize\epsffile{busyboxConf2.eps}\end{center}\caption{BusyBox configuartion}\label{fig:busyboxcf2}\end{figure}
-
-After you finish the configuration, save your configuration
-and quit the window. Then, to make the Busybox tools, type
\begin{verbatim}
-make
+nod /dev/console 0600 0 0 c 5 1
\end{verbatim}
-And then install the tools to your inital ramdisk directory
+
+\noindent
+The ``\verb|root_files|" file is used when building the Linux kernel in the
+section Configuring and building the Linux kernel. Finally, create any
+additional directories and copy any additional files that you need. Your initial
+ramdisk filesystem is prepped and ready for installation of the BusyBox tools as
+described in the section Configuring and installing BusyBox tools.

+\section{Configuring and installing BusyBox tools}
+
+BusyBox is a software application released as Free software under the GNU GPL
+that provides many standard Unix tools. BusyBox combines tiny versions of many
+common UNIX utilities into a single, small executable. For more details on
+BusyBox visit \url{http://busybox.net}. To configure BusyBox, in the
+``\verb+busybox/+" directory, type the following:
\begin{verbatim}
-make install
+[jdoe@newskysaw busybox]$ make menuconfig
\end{verbatim}
-\section{Configure and Compile Linux Kernel}
+\noindent
+or
+
+\begin{verbatim}
+[jdoe@newskysaw busybox]$ make xconfig
+\end{verbatim}
-Go to \verb|linux-2.6.30.y/| directory (or whatever your
-Linux kernel source directory). Type
+\noindent
+The BusyBox tools will be installed in the guest's initial ramdisk filesystem;
+you can add any tools that you need. There are two required configuration
+options. In the
+``\verb|BusyBox settings->Build Options|" menu check the
+``\verb|Build BusyBox as a static binary (no shared libs)|" option, as shown in
+figure \ref{fig:busyboxcf1}, and in the
+``\verb|BusyBox settings->Installation Options|" menu set the
+``\verb|Busybox installation prefix|" to the path of the
+``\verb|initrd/initramfs|" directory, as shown in figure \ref{fig:busyboxcf2}.
+After you finish configuring BusyBox, save your configuration and quit the
+window. Then, to make the BusyBox tools, type the following:
\begin{verbatim}
-make menuconfig
-make xconfig (X version)
+[jdoe@newskysaw busybox]$ make
+\end{verbatim}
+Install the tools to the guest's initial ramdisk filesystem directory:
+\begin{verbatim}
+[jdoe@newskysaw busybox]$ make install
\end{verbatim}
-To configure the kernel as your need.
-There is a customed configuration file "\verb|jrl-default-config|"
-which is configured with minimal kernel options (all of
-unnecessary stuffs are turned off to keep guest booting process faster).

+\section{Configuring and building the Linux kernel}
-\section{Configure guest devices}
-Checkout the updated Palacios repository to \verb|palacios/|.
-(You can find the instruction of how to get the Palacios and
-Kitten repository in http://www.v3vee.org/palacios/).
+The following procedure demonstrates how to configure and build a 32-bit Linux
+kernel. Change to the ``\verb|linux-2.6.30.y/|" directory. There is a custom
+configuration file ``\verb|jrl-default-config|" which is configured with minimal
+kernel options (all unnecessary options are removed to keep the guest booting
+process fast). If you are using the custom configuration file type the
+following:
-In the "\verb|palacios/utils/guest_creator|", Type
\begin{verbatim}
-make
+[jdoe@newskysaw linux-2.6.30.y]$ cp jrl-default-config .config
\end{verbatim}
-You will get the guest configuration files creator "\verb|build_vm|".
-The guest configuration file is using XML format. There is a sample configuration file: \verb|default.xml|.
-You can create your own guest configuration, after creating your file, type
+\noindent
+Configure the kernel to meet your requirements. For more on configuring and
+building Linux kernels, check online. Type the following:
\begin{verbatim}
-./build_vm myconfig.xml -o guest.iso
+[jdoe@newskysaw linux-2.6.30.y]$ make ARCH=i386 menuconfig
\end{verbatim}
-Where \verb+myconfig.xml+ is your guest configuration file,
-and \verb+guest.iso+ is the output image file that can be
-feed into kitten¡¯s configuration (see next section).
+\noindent
+or
-\section{Configure and Make Palacios and Kitten}
-\subsection*{Configure and build Palacios}
+\begin{verbatim}
+[jdoe@newskysaw linux-2.6.30.y]$ make ARCH=i386 xconfig
+\end{verbatim}
-You can find the detail manual of getting and building Palacios and Kitten
-from scratch in the Palacios website (http://www.v3vee.org/palacios).
-Here we only give the specific requirements related to the booting guest procedure.
+\noindent
+The kernel must be configured with the initial ramdisk file system directory
+(e.g. ``\verb|initrd/initramfs/|"): in the ``\verb|General setup|" menu under
+option
+``\verb|Initial RAM filesystem and RAM disk support|" set the
+``\verb|Initramfs source file(s)|" option to the path of the
+``\verb|initrd/initramfs/|" directory, as shown in figure \ref{fig:linuxcf}.
+Additionally, if you are using the ``\verb|root_files|" file to create devices
+files, add the ``\verb|root_files|" file path, separated by a space, after the
+initial ramdisk filesystem directory. When you are finished configuring the
+kernel, save your configuration, and build a bootable ISO image:
-To configure Palacios, in Palacios root directory, such as \verb+palacios/+, type
+\begin{verbatim}
+[jdoe@newskysaw linux-2.6.30.y]$ make ARCH=i386 isoimage
+\end{verbatim}
+
+\noindent
+The ISO image can be found here: ``\verb|arch/x86/boot/image.iso|", and will be
+used in the section Configuring and building the guest image.
+
+
+\section{Configuring and building the guest image}
+
+Checkout the updated Palacios repository to the ``\verb|palacios/|" directory.
+(You can find instructions for checking out the Palacios repository at
+\url{http://www.v3vee.org/palacios/}). The guest creator utility is required for
+building the guest image. Change to the ``\verb|palacios/utils/guest_creator|"
+directory and build the guest creator utility:
+
+\begin{verbatim}
+[jdoe@newskysaw guest_creator]$ make
+\end{verbatim}
+\noindent
+You will get the ``\verb|build_vm|" utility:
\begin{verbatim}
-make config
+[jdoe@newskysaw guest_creator]$ file build_vm
+build_vm: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked
+(uses shared libs), for GNU/Linux 2.6.9, not stripped
+\end{verbatim}
+
+\noindent
+The guest configuration file is written in XML. A sample configuration file is
+provided: ``\verb|default.xml|". Make a copy of the default configuration file
+named ``\verb|myconfig.xml|" and edit the configuration elements that you are
+interested in (if a device is included in the guest configuration file, it
+must be configured in the section Configuring and building Palacios or the guest
+will not boot). Of particular importance is the ``\verb|files|" element. Comment
+out this attribute:
+
+\begin{verbatim}
+<file id="boot-cd" filename="/home/jarusl/image.iso" />
+\end{verbatim}
+
+\noindent
+Add an attribute that specifies the location of the Linux ISO image:
+
+\begin{verbatim}
+<file id="boot-cd" filename="../../../linux-2.6.30.y/arch/x86/boot/image.iso" />
+\end{verbatim}
+
+\noindent
+When you are finished editing the guest configuration save the configuration
+file. The guest image consists of the guest configuration file and the Linux
+ISO image. Build the guest image with the guest creator utility:
+
+\begin{verbatim}
+[jdoe@newskysaw guest_creator]$ ./build_vm myconfig.xml -o guest.iso
+\end{verbatim}
+
+\noindent
+The guest image, ``\verb+guest.iso+", is embedded in Kitten's
+``\verb|init_task|" in the section Configuring and building Kitten.
