1. Good catch, updated HOWTO
2. It is needed on CentOS 5.5. Otherwise it doesn't work, updated HOWTO with a
note.

5.5
I have two more questions regarding yours "Howto"
1. Quote
***********************************************************************************************
OR, add the following to /etc/rc.local (I had trouble making the modprobe work)
if ( uname -r | grep "2.6.32.21") ; then
for mod in xen-evtchn xen-netback xen-blkback xenfs; do
/sbin/modprobe $mod
done
/etc/init.d/xend restart
fi
**************************************************************
Xend will fail to start as service if module xenfs has not been loaded yet. So
nothing to restart. Should be
service xend start
2.Quote
Install Xen and kernel
*******************************************************************************************
make install-xen
make install-tools PYTHON_PREFIX_ARG=
cd build-*
make modules_install
make install
***********************************************************
I would guess that on CentOS 5.5 just
make install-tools
due to standard default location of python packages
/usr/lib/python2.x/site-packages . I haven't alive CentOS 5.5
instance, but on Fedoras it's unnecessary
Boris.

If i will follow :-
http://ppadala.net/blog/2010/09/how-to-setup-xen4-and-pvops-2-6-32-x-on-centos-5-5-using-gitco-repository/
Recommended .config (fragment)
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XEN_BACKEND=y
CONFIG_XEN_BLKDEV_BACKEND=y
CONFIG_XEN_NETDEV_BACKEND=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
I believe in this case modules :-
xen-evtchn xen-netback xen-blkback xenfs
won't be created because they are hard linked to kernel.
To get them as modules i need :-
CONFIG_XEN_DEV_EVTCHN=m
CONFIG_XEN_BACKEND=y
CONFIG_XEN_BLKDEV_BACKEND=m
CONFIG_XEN_NETDEV_BACKEND=m
CONFIG_XENFS=m
At least on my system (F14) with .config
Fragment from .config
#
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XEN_BACKEND=y
CONFIG_XEN_NETDEV_BACKEND=m
CONFIG_XEN_BLKDEV_BACKEND=y
CONFIG_XEN_BLKDEV_TAP=y
#
[root@fedora14 2.6.32.23]# pwd
/lib/modules/2.6.32.23
[root@fedora14 2.6.32.23]# find . -name "xen-*back.ko" -print
./kernel/drivers/xen/netback/xen-netback.ko
[root@fedora14 2.6.32.23]# find . -name "xen-evtchn.ko" -print
Module xen-netback.ko has been created only due to :-
CONFIG_XEN_NETDEV_BACKEND=m
May be i am missing something here ?
Boris.
P.S.
I just need xen-netback to be loaded as module for OpenIndiana 147 PV Guest
stable networking with PVOPS kernel ( OSOL 134 aswell). In other words i need
to configure PVOPS kernel like XenLinux kernel in regards of loading xen
backend drivers.

Thanks for the tutorials!
