You can pretty much find all the information you need in the
documentation and readme.  Go ahead and install xen.  Find the kernel
you want to customize (e.g., 2.4 or 2.6, xen0 or xenU) in the xen
directory.  Customize it as with any kernel but adding the setting
ARCH=xen, e.g.,

make ARCH=xen menuconfig
make ARCH=xen
make ARCH=xen modules
etc.

Hope this helps.  If you need more help, I do have a step by step
instruction sheet on how we set it up in our test lab.  It is very
specific to us.  I sent it to some others on this list at their request.
Perhaps they could comment if they found it helpful; I won't be the
least bit offended if they say it was not -- it was very specific and
based upon our first, ignorant attempt!

 

 

When I untar the xen sources, I get a top level dir "xen-2.0" under which there is a directory called "xen". Per your instruction "Find the kernel you want to customize (e.g., 2.4 or 2.6, xen0 or xenU) in the xen directory. " , I did the following:

 

cd xen-2.0

mv xen xen_orig

ln -s /usr/src/linux xen  (since I want to customize the sles9 kernel residing in /usr/src/linux)

Then I try to configure the kernel but this failed (as expected, since it does not know anything about xen):

 

# cd /xen/xen-2.0/xen

# make ARCH=xen menuconfig
scripts/kconfig/mconf arch/xen/Kconfig
can't find file arch/xen/Kconfig
make[1]: *** [menuconfig] Error 1
make: *** [menuconfig] Error 2
 

I guess I need to apply some patch to the sles kernel. The only patch I find in the xen sources is :

# cd /xen/xen-2.0/patches/linux-2.6.11

# ls
.  ..  .makedep  agpgart.patch  iomap.patch  linux-2.6.11.10.patch  nettel.patch
 

which seem to be for the 2.6.11 kernel, but the sles9 kernel I have is  2.6.5-7.97-smp.

 

John, If you can send me your instructions from your test lab, that will be really helpful.

 

thanks

Shavian.
