# bk clone bk://xen.bkbits.net/xen-2.0.bk

Under your current directory, a new directory named xen-2.0.bk has been

created, which contains all the source code for Xen, the OS ports, and the control

tools. You can update your repository with the latest changes at any time by

running:

# cd xen-2.0.bk # to change into the local repository

# bk pull # to update the repository

2.3.2 Building from Source

The top-level Xen Makeﬁle includes a target ‘world’ that will do the following:

• Build Xen

• Build the control tools, including xend

• Download (if necessary) and unpack the Linux 2.6 source code, and patch it for

use with Xen

• Build a Linux kernel to use in domain 0 and a smaller unprivileged kernel, which

can optionally be used for unprivileged virtual machines.

After the build has completed you should have a top-level directory called dist/

in which all resulting targets will be placed; of particular interest are the two kernels

XenLinux kernel images, one with a ‘-xen0’ extension which contains hardware device

drivers and drivers for Xen’s virtual devices, and one with a ‘-xenU’ extension that just

contains the virtual ones. These are found in dist/install/boot/ along with the

image for Xen itself and the conﬁguration ﬁles used during the build.

The NetBSD port can be built using:

# make netbsd20

NetBSD port is built using a snapshot of the netbsd-2-0 cvs branch. The snapshot is

downloaded as part of the build process, if it is not yet present in the NETBSD SRC PATH

search path. The build process also downloads a toolchain which includes all the tools

necessary to build the NetBSD kernel under Linux.

To customize further the set of kernels built you need to edit the top-level Makeﬁle.

Look for the line:

KERNELS ?= mk.linux-2.6-xen0 mk.linux-2.6-xenU

You can edit this line to include any set of operating system kernels which have con-

ﬁgurations in the top-level buildconfigs/ directory, for example mk.linux-2.4-

xenU to build a Linux 2.4 kernel containing only virtual device drivers.
