[Xen-devel] [HOWTO] Setting up Xen4 + pvops 2.6.32.21.x on CentOS 5.5
Hi, I spent some time configuring the latest Xen with pvops 2.6.32.x on CentOS 5.5. It hasn¹t been easy, to say the least. My HOWTOs on this are located at http://ppadala.net/blog/2010/09/how-to-setup-xen4-pvops-2-6-32-x-on-centos-5 -5/ and http://ppadala.net/blog/2010/09/how-to-setup-xen4-and-pvops-2-6-32-x-on-cent os-5-5-using-gitco-repository/ Hope they are helpful. Any comments are welcome. Feel free to add this to Xen4 Wiki.

RE: [Xen-devel] [HOWTO] Setting up Xen4 + pvops 2.6.32.21.x on CentOS 5.5
Pradeep, Yours "Howto" worked for me in some unexpected way. There is well known issue with failure OSOL 134 ( Indiana in meantime) DHCPREQUEST success on system with pvops kernel mostly have all xen backend drivers hard linked to the kernel. At the same time same OSOL 134 behaves fine on OpenSuse 11.3 , loading xen-backend drivers via xend at every boot up. I just decided try to load as module xen-netback on systems with pvops kernel ( on top of F13,Ubuntu 10.04.1 Server) and got positive results. The final conclusion is :- for OSOL 134 (OI 147) xen-netback driver should be loaded as module, otherwise in 90% off attempts DHCP request for Solaris DomU will fail right away.

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

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.
