[Xen-users] should packages be removed before installing xen from source?

I have some xen servers running on sles10sp2. I''d like to try and run
the latest stable release from source to see if it improves any issues
I''m having. Should I remove the xen packages before installing from
source?

Thanks,
James

Yes, you will almost certainly need to do this, as the locations for source file
installation and the packages are different, and this can lead to (and has led
to, in my experience) Xen getting confused about which Python files it needs to
run.  Removing the Xen packages should help resolve these issues.  Once caveat
to this is that you''ll probably have to build *everything* - packages
like virt-manager and libvirt require the Xen packages to be installed, so you
should either plan on building new Xen packages and installing those, or making
sure you download and compile code for all of the components, not just the xen-*
packages.

Nick, 

I uninstalled all the xen packages, including all the supporting virt
stuff. I installed a newer kernel-xen and kernel-source. I copied xen.gz
from 3.4.1 to /boot and then booted the new kernel. 

When I try to make dist on 3.4.1 it errors out saying it can''t find the
source files:
make[2]: Entering directory `/install/xen-3.4.1''
set -e ; \
if [ ! -e linux-2.6.18-xen.hg/.hg ] ; then \
    __repo=$(sh buildconfigs/select-repository
linux-2.6.18-xen.hg .:..) ; \
    if [ -d ${__repo} ] ; then \
        echo "Linking ${__repo} to linux-2.6.18-xen.hg." ; \
        ln -s ${__repo} linux-2.6.18-xen.hg ; \
    else \
        echo "Cloning ${__repo} to linux-2.6.18-xen.hg." ; \
        hg clone ${__repo#file://} linux-2.6.18-xen.hg ; \
    fi ; \
else \
    __parent=$(hg -R linux-2.6.18-xen.hg path default) ; \
    echo "Pulling changes from ${__parent} into linux-2.6.18-xen.hg."
;
\
    hg -R linux-2.6.18-xen.hg pull ${__parent} ; \
fi

Falling back to linux-2.6.18-xen Mercurial repository.
Cloning http://xenbits.xensource.com/linux-2.6.18-xen.hg to

make[1]: *** [linux-2.6-xen-install] Error 2
make[1]: Leaving directory `/install/xen-3.4.1''
make: *** [install-kernels] Error 1

I think it''s looking at the wrong kernel. I''m running
2.6.16.60-0.42.5-xen with the source at /usr/src/linux, but it seems to
be looking for 2.6.18-xen. Do I need to install that specific kernel?

If I do need 2.6.18-xen, where do I get it? Looking at kernel.org but
not finding it. 

Thanks,
James

Oops, I see it right on the xen.org website sorry. Downloading it now...

I installed the new 2.6.18-xen kernel. I did:
make menuconfig (basically took defaults)
make dist
make install

This updated /boot/grub/menu.lst. When I try and boot the new kernel I
get his error:

Error 13: Invalid or unsupported executable format

If you google this you get 1000''s of hits, most seem to have something
to do with windows. Anybody know how to fix this for my situation?

Thanks,
James

They appear to be the same type:

# file vmlinuz-2.6.18.8-xen
vmlinuz-2.6.18.8-xen: gzip compressed data, from Unix, max compression
# file vmlinuz-2.6.16.60-0.42.5-xen
vmlinuz-2.6.16.60-0.42.5-xen: gzip compressed data, from Unix, max compression

It's actually looking for the Mercurial command so that it can download
the latest version of the Linux 2.6.18 kernel from the repository.  You
can either download the source yourself, download the Mercurial and have
it download the source, or you can use various arguments to the make
command to avoid building the Xen/Linux kernel at all.

So you''re saying I can build xen-3.4.1 with the current running kernel?
In this case it''s 2.6.16.60-0.42.5-xen.

Where can I find the make commands you are referring to? 

Thanks,
James
