[Xen-users] Problem compiling a custom kernel for xen-3.0

["Angel L. Mateo" <amateo@xxxxx>]

Hello,

        I am trying to run xen-3.0 in some of my dell servers. I have tried the
binary distribution of xen, but it doesn't boot in my test system (a
dell poweredge 750) because a module driver problem (I get an error
message during booting saying it doesn't load a NFS root filesystem).

        So I am trying to compile a custom kernel. So I have downloaded linux
source 2.6.12. I am doing the next steps (found at
http://www.howtoforge.com/perfect_xen_setup_debian_ubuntu_p3):

1. cp -al linux-2.6.12 linux-2.6.12-xen0
2. cd xen-3.0.1/linux-2.6.11-xen-sparse/
3. ./mkbuildtree ../../linux-2.6.12-xen0/
4. cd ../..
5. echo "-xen0" > linux-2.6.12-xen0/localversion-xen
6. diff -Naur linux-2.6.12 linux-2.6.12-xen0 >
archive/linux-2.6.12-xen0.patch

7. cd linux-2.6.12
8. patch -p1 < ../archive/linux-2.6.12-xen0.patch
9. cd ../
10. mkdir install
11. cd linux-2.6.12-xen0
12. cp arch/xen/configs/xen0_defconfig .config
13. ARCH=xen; INSTALL_PATH=../install; INSTALL_MOD_PATH=../install
14. export ARCH INSTALL_PATH INSTALL_MOD_PATH
15. make oldconfig
16. make menuconfig
17. make modules

        But I get an error:
  CHK     include/linux/version.h
  CC      arch/i386/kernel/asm-offsets.s

make[1]: *** [arch/i386/kernel/asm-offsets.s] Error 1
make: *** [arch/i386/kernel/asm-offsets.s] Error 2

        so I can't compile it. I have tried to compile the 2.6.12 kernel with
the same configuration (but without xen options) and it compiles
perfectly.

        Any idea?
