Hey all, I have moved 10_Linux to 50_Linux and ran update-grub which is fine. The problem I have is that there is xen-syms in /boot And that is being put first in the boot list which is incorrect. How do you make /xen.gz at the top so it is booted first?

Indeed,
I searched deeper and found that grub use dpkg --compare-version to find the
latest version , if you''re not on debian i suppose it''s
another method
So it clean up the names with :
echo <your-version> |sed -e
"s/[^-]*-//;s/[._-]\(pre\|rc\|test\|git\|old\|trunk\)/~/g"
and then compare it with :
dpkg --compare-version <version1> gt <version2>
exemple :
dpkg --compare-versions 2.6.32 gt syms-2.6.32
wich gives syms winner, never mind the numbers
3 possible workaround :
The simplest is to rename your xen hypervisors, by prepending
''xen-'' to them : mv xen-4.0.2-rc3-pre.gz
xen-xen-4.0.2-rc3-pre.gz
i tested and it works.
The second is to modify the regexp : i didn''t even tried ^^
The third is to patch : /usr/lib/grub/grub-mkconfig_lib
add the bold lines to this function :
version_test_gt ()
{
local
sedexp="s/[^-]*-//;s/[._-]\(pre\|rc\|test\|git\|old\|trunk\)/~\1/g"
local a=`echo $1 | sed -e "$sedexp"`
local b=`echo $2 | sed -e "$sedexp"`
local cmp=gt
if [ "x$b" = "x" ] ; then
return 0
fi
case $a:$b in
*.old:*.old) ;;
*.old:*) a=`echo -n $a | sed -e s/\.old$//` ; cmp=gt ;;
*:*.old) b=`echo -n $b | sed -e s/\.old$//` ; cmp=ge ;;
syms-*:syms-*) cmp=gt;;
*:syms-*) cmp=lt;;
syms-*:*) cmp=lt;;
esac
dpkg --compare-versions "$a" $cmp "$b"
return $?
}
I tested too, it works fine and it''s my prefered.

Brilliant, it worked!
I used the 3rd option so everthing else it left as standard. Im not sure how
you managed to figure that out but thanks very much.
BTW what does
syms-*:syms-*) cmp=gt;;
*:syms-*) cmp=lt;;
syms-*:*) cmp=lt;;
actually do?

The issue is when compiling from source it creates another file in /boot called xen-syms-4.1.0 When running update-grub its puts the xen-syms-4.0.1 higher in the list but its not correct, it should be /xen.gz or similar. When the server boots it fails therefore you have to manually select the correct boot entry, obviously not practical. You can either manually edit /boot/grub/grub.cfg which isn''t the right way or edit the file that that the previous person mentioned, and this worked. Hope that makes sense.

Has anyone tried to write a patch to fix this? If someone was so inclined to submit such a patch to the Debian BTS, that would be awesome :) I know the Debian Xen packages (at least the 4.0.1 stuff) do not put this xen-syms file and if you delete it, from my experience everything still works. If you are not as daring to delete it, you may also place this file in another folder such as /boot/xen/ and the non-working grub entry is no longer created as well. -M _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi, If I recall most versions I have installed put a syms file in /boot I know the deb packages don''t but I rarely use debs for xen, mainly because I can only upgrade when someone writes a new deb which is rare and upgrading from source over debs has always caused more problems than its worth. If the syms file can be deleted then that''s fine but what is its purpose?

Hey Ian, I believe the symbols are used for debugging, and helping trace crashes. I could be wrong, but I believe it is fair to say its like the system.map[1] file equivalent for the Xen Hypervisor.
