problems with openssi and xen

Hi

I am trying to build an openssi cluster inside of a xen virtualisation
and having some problems. I am new to this, so sure some of you can help.

First I built a xen host and guest kernel using the current xen version,
 which is xen 3.1.0 with linux kernel 2.6.18. The xen environment works,
i can boot serval guests, debian sarge or etch.
Then I tried to build an openssi guest kernel but get compile errors. I
used ci and openssi from cvs, and a vanilla kernel 2.6.10 (Is it still
2.6.10 ?). Then make xenkern, copied
openssi/kernel.configs/kernel-ssi-xenU.config to linux-ssi/.config,
make ARCH=xen oldconfig and make ARCH=xen vmlinuz which dies with

   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

Furthermore there is no file cputime.h in the whole source tree.

I also tried to boot the precompiled openssi xen guest kernel from
http://deb.openssi.org/openssi-v2/xenU-vmlinuz, but xen dies.
 mrpink:~# xm create -c /etc/xen/guests/guest01.cfg
 Using config file "/etc/xen/guests/guest01.cfg".
 Error: (2, 'Invalid kernel', 'elf_xen_note_check: ERROR: Xen will only
load images built for Xen v3.0\n')

So I need to know how to compile this openssi-xen guest kernel to boot
inside my xen 3.1.0 host system.
Any help is appreciated, thank you.
