Xen users - May 2005 - Re: Problems building a xen0 kernel on Suse 9.3

Following up my previous post and searching around a
bit, Itried the following:

cd /usr/src/linux
make mrproper
./arch/i386/defconfig.xen .config
make ARCH=xen menuconfig (I just change general
setup-> Local version)
make ARCH=xen prepare

make: Zirkuläre Datei

wird nicht verwendet.

  CHK     include/asm-i386/asm_offsets.h
  UPD     include/asm-i386/asm_offsets.h

there are symlinks in ./include which I do not
understand:
~.asm-ignore -> asm-xen (delete or not?)
~asm -> asm-i386 (shouldn''t that point to asm-xen?)

nevertheless I continue:
make ARCH=xen
  CHK     include/linux/version.h
  SYMLINK include/asm -> include/asm-i386
make[1]: »arch/i386/kernel/asm-offsets.s« ist bereits
aktualisiert.

next I removed support for reiserfs4 and BeFs, same
results

Any hints?

Have you seen Gert Knorr''s reply to Xen-users?
  http://lists.xensource.com/archives/html/xen-users/2005-05/msg00443.html

Thank you Gert!

I think you are on the right track using KOTD, but are you aware that
that you need two pieces to get sources that you can build the SuSE
Xen kernel from?

 
ftp://your.suse.mirror.here/pub/projects/kernel/kotd/i386/HEAD/kernel-xen-2.6.11.10-20050524103609.abuild-extra.tar.gz
 
ftp://your.suse.mirror.here/pub/projects/kernel/kotd/i386/HEAD/kernel-source-2.6.11.10-20050524103609.src.rpm

In fact I tried using the stuff in following place
instead:
  ftp://your.suse.mirror.here/pub/projects/kernel/kotd/9.3-i386/SL93_BRANCH/

i.e. not kernel-source-<version>.i586.rpm
but kernel-source-<version>.src.rpm
and kernel-xen-<version>.abuild-extra.tar.gz

you need to do

rpm -i kernel-source-<version>.src.rpm
cat kernel-xen-<version>.abuild-extra.tar.gz | \
   (cd /usr/src/packages/SOURCE/ && tar xf - )

Then either build using rpmbuild and the kernel-xen.spec file
or manually with make ARCH=xen config ; make ARCH=xen

Remember to set CONFIG_BLK_DEV_MD=y

I am busy compiling this at the moment :)

Not sure how often this is updated, but I think tomorrow that place
should have binary rpms configured with CONFIG_BLK_DEV_MD=y
