it will then add the Xen architecture files. You can tell the
makefile the location of the appropriate Linux compressed tar file by
setting the LINUX\_SRC environment variable, e.g. \\
-\verb!# LINUX_SRC=/tmp/linux-2.6.8.1.tar.bz2 make world! \\ or by
+\verb!# LINUX_SRC=/tmp/linux-2.6.9.tar.bz2 make world! \\ or by
placing the tar file somewhere in the search path of {\tt
LINUX\_SRC\_PATH} which defaults to `{\tt .:..}'. If the makefile
can't find a suitable kernel tar file it attempts to download it from
If you have an existing Linux kernel configuration that you would like
to use for domain 0, you should copy it to

+install/boot/config-2.6.9-xen0. During the first build, you may be
asked about some Xen-specific options. We advise accepting the
defaults for these options.
Files in \path{install/boot/} include:
\begin{itemize}
\item \path{install/boot/xen.gz} The Xen 'kernel'

The difference between the two Linux kernels that are built is due to
The \path{install/boot} directory will also contain the config files
used for building the XenLinux kernels, and also versions of Xen and

\begin{description}
\item[kernel] Path to the kernel image (on the server).
\item[memory] Memory size in megabytes.
\item[cpu] CPU to assign this domain to.
\item[nics] Number of virtual network interfaces.
-\item[vif] List of MAC addresses (random addresses are assigned if not given).
-\item[disk] Regions of disk to export to the domain.
+\item[vif] List of MAC addresses (random addresses are assigned if not given) and /

+\item[disk] List of block devices to export to the domain. e.g. \\
+ \verb_disk = [ 'phy:hda1,sda1,r' ]_ \\
+ exports device \path{/dev/hda1} to the domain, as \path{/dev/sda1} with

\item[dhcp] Set to {\tt 'dhcp'} if you want to DHCP allocate the IP address.
\item[netmask] IP netmask.
\item[gateway] IP address for the gateway (if any).
