Re: [Xen-users] PUZZLES WITH A CUSTOM XENLINUX BUILD

[Andreas Seuss <mam04exx@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

you did everything in the right way. A 'make world' will download the
respective kernel sources from kernel.org and unpack them into two
directories. The make file applies the necessary patches. In my case,
it's linux-2.6.11-xen0 and linux-2.6.11-xenU under ../xen-2.0/. I build
from the stable sources, but it works the same way.

With the "download (if necessary) and unpack the Linux 2.6 source code"
is meant, that make will download the kernel in case it is not already
in that directory. If you called "make world" for the first time it will
download the kernel-src.

In your case I would do the following:

'make world'  #It builds xen and downloads and compiles the kernels

Then cd into the directory of the kernel you want to customize (probably
xen0)

'make ARCH=xen xconfig' (or make ARCH=xen oldconfig with your existing
config file)

go back to the main xen directory and do a 'make kernels'

And then, to install the xen binaries and the kernels: 'make install'.
