2.3.3 Custom XenLinux Builds

If you wish to build a customized XenLinux kernel (e.g. to support additional devices

or enable distribution-required features), you can use the standard Linux conﬁguration

mechanisms, specifying that the architecture being built for is xen, e.g:

# cd linux-2.6.11-xen0

# make ARCH=xen xconfig

# cd ..

# make

You can also copy an existing Linux conﬁguration (.config) into linux-2.6.11-

xen0 and execute:

# make ARCH=xen oldconfig

You may be prompted with some Xen-speciﬁc options; we advise accepting the de-

faults for these options.

Note that the only difference between the two types of Linux kernel that are built is

the conﬁguration ﬁle used for each. The ”U” sufﬁxed (unprivileged) versions don’t

contain any of the physical hardware device drivers, leading to a 30% reduction in

size; hence you may prefer these for your non-privileged domains. The ‘0’ sufﬁxed

privileged versions can be used to boot the system, as well as in driver domains and

unprivileged domains.

2.3.4 Installing the Binaries

The ﬁles produced by the build process are stored under the dist/install/ direc-

tory. To install them in their default locations, do:

# make install

Alternatively, users with special installation requirements may wish to install them

manually by copying the ﬁles to their appropriate destinations.

The dist/install/boot directory will also contain the conﬁg ﬁles used for build-

ing the XenLinux kernels, and also versions of Xen and XenLinux kernels that contain

debug symbols (xen-syms-2.0.6 and vmlinux-syms-2.6.11.11-xen0) which

are essential for interpreting crash dumps. Retain these ﬁles as the developers may

wish to see them if you post on the mailing list.

2.4 Conﬁguration

Once you have built and installed the Xen distribution, it is simple to prepare the

machine for booting and running Xen.
