thanks for the quick answer.

so what is the proper procedure for building a xen kernel ?

this is what i do, knowing that xen sources are located
in /xen/xen-2.0 :

#  cd /xen/xen-2.0/linux-2.6.10-xen0/
# make menuconfig ARCH=xen
...
# cd /xen/xen-2.0/
# make
# ./install.sh

am i missing something ?

regards
