[Xen-devel] Invalid or unsupported executable format, or is it a reiserfs problem?
Our newly build xen kernel does not boot. The error message is : Invalid or unsupported executable format. I have build xen from the xen-2.0.4 source (make world, make install) on a debian sarge system. I have not changed any of the kernel configurations, I did make an initrd image. The entry in my menu.lst is : title Debian GNU/Linux, kernel 2.6.10-xen0 root (hd0,0) # I also tried without this line. kernel /boot/xen.gz dom0_mem=64000 module /boot/vmlinuz-2.6.10-xen0 root=/dev/hda1 ro module /boot/initrd.img-2.6.10-xen0 # Also tried without this line The server''s / (/boot) partition is reiserfs. I wonder if this is the problem? I found messages saying that it doesn''t work with reiserfs and others that say it should work. What is the final answer? Looking in the kernel config file: reiserfs is build into the kernel, not as a module. As a side note: the standard debian 2.6.8-2 kernel works perfectly. == from the grub manual == Invalid or unsupported executable format: This error is returned if the kernel image being loaded is not recognized as Multiboot or one of the supported native formats (Linux zImage or bzImage, FreeBSD, or NetBSD). == end == since xen is multiboot and I would be surprised that the xen.gz kernel image file is not in native format; I have a strong feeling that this error message is not giving the root cause. Anybody any thoughts?

That said I believe some people have reported happiness with reiserfs.

What does `file /boot/xen.gz'' say?
/boot/xen.gz: gzip compressed data, from Unix, max compression
What does `cat /boot/xen.gz | gunzip -c | file -` say?
/dev/stdin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
statically linked, stripped

You may well be right; we''ve not used reiserfs extensively and so
it is possible some weird condition is being triggered. That said
I believe some people have reported happiness with reiserfs.
Can you reproduce the error with just xen (i.e. no xenlinux and
no initrd and hence no "module" lines at all)?
I think yes, the machine instantly reboots like it did with xenlinux
"enabled". The only way to prevent the instant reboot was by starting
in
recovery mode (= passing "single" as an argument to the xenlinux
kernel). Then I saw error 13: Invalid or unsupported executable format.
I also tried with -noreboot argument like the grub documentation says,
but that had no effect.
We have no serial console available (no serial cable).
Thinking ahead, suppose reiserfs has to be dropped, will it suffice to
just convert the /boot partition to ext3 or does the entire / partition
need to be converted?
Thanx in advance,

Hmm: what is the menu.lst you use for that? In particular, is the
kernel you boot in the same directory as xen.gz?
=== original debian entry in menu.lst (grub-update)==title Debian
GNU/Linux, kernel 2.6.8-2-386
root (hd0,0)
kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/hda1 ro
initrd /boot/initrd.img-2.6.8-2-386
savedefault
boot
=== end ==
Yes, xen.gz is in the same directory (/boot).
Nothing about -o notail inhere.
What''s the overall makeup of your partitions + filesystems in the
machine? I''m guessing /dev/hda1 is { /boot, reiserfs } -- what
about the rest of the system?
/dev/hda1 / (reiserfs 700MB, no separate partition for /boot)
/dev/hda2 swap (120 MB)
/dev/hda5 /home (reiserfs 1,3GB)
> Thinking ahead, suppose reiserfs has to be dropped, will it suffice to

Well ideally it should all "just work" even with reiserfs as
/boot.
How did you get xen.gz onto /boot? Did you copy it from an ext2/3
partition? There seems to be something weird about reiserfs and
grub involving the "-notail" mount option...
xen-2.0.4.tgz was copied and unfolded in my /home/<user> directory
cd xen-2.0
make world
wait, wait very long (200Mhz, testing machine - proof of concept setup)
make install # this copied everything in place automatically: xen.gz
and vmlinuz-2.6.10-xen0 and the other stuff to /boot, /etc/init.d
/lib/modules, ...
mkinitrd -o /boot/initrd.img-2.6.10-xen0 2.6.10-xen0
change menu.lst in /boot/grub, add the xen stuff as described earlier
reboot -> oops: not working ... damn
Would an attache serial console provide more information that is usefull
to you? If yes, I go buy a cable.

Re: [Xen-devel] Invalid or unsupported executable format, or is it a reiserfs problem?
I;m using reiserfs without any issues, however I do have the following in my /etc/fstab: /dev/md2 / reiserfs noatime 0 0 /dev/md0 /boot reiserfs noatime,notail 0 0 maybe this helps? B.

Re: [Xen-devel] Invalid or unsupported executable format, or is it a reiserfs problem?
I have reinstalled that machine with a ext3 /boot partition and a
reiserfs / partition
/dev/hda1 /boot (ext3)
/dev/hda2 swap
/dev/hda4 / (reiserfs)
Installation from source
tar xvf xen-2.0.4.tgz
cd xen-2.0
make world
make install
mkinitrd -o /boot/initrd.img-2.6.10-xen0 2.6.10-xen0
Edit menu.lst in /boot/grub
add serial support for grub:
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console
Entry for Xen:
title Xen-2.0
root (hd0,0) # also tried without
kernel /xen.gz dom0_mem=64000
module /vmlinux-2.6.10-xen0 root=/dev/hda4 ro console=tty0
console=ttyS0,115200n8
module /initrd.img-2.6.10-xen0 #also tried without
Connect to another host with null modem cable.
start minicom and configure with serial parameters to 115200,
parity=no, data=8, stop=1
hardware flow control = yes
software flow control = no
terminal = VT102
backspace sends BS
Result:
-------
The xen kernel does not boot
I don''t see anything on the terminal from grub or xenlinux (I do see
the output when booting the normal debian kernel)
I am lost !
Does anybody know how to go on from here or do I have no other choice
then to download fedora core 3 and try it with that distribution?
Thanks in advance for any help.

Filip Sergeys

How did you get xen.gz onto /boot? Did you copy it from an ext2/3
partition? There seems to be something weird about reiserfs and
grub involving the "-notail" mount option...

[Xen-devel] xen brings machine in a boot loop. Serial console output attached.
was subject: Re: [Xen-devel] Invalid or unsupported executable format,
or is it a reiserfs problem?
continuation under new subject header
OK, made the changes to menu.lst, also grub serial console works
(unreleated error)
The entire root (including /boot) partition is now ext3.
menu.lst looks like:
=== start ==title Xen 2.0
kernel /boot/xen.gz dom0_mem=64000 com1=115200n81
module /boot/vmlinuz-2.6.10-xen0 root=/dev/hda1 ro console=tty0
console=ttyS0
module /boot/initrd.img-2.6.10-xen0
=== end ==
this is what the serial console shows when booted without initrd:
=== start ==kernel /boot/xen.gz dom0_mem=64000 com1=115200,n81
[Multiboot-elf, <0x100000:0x3ef7c:0x3536c>, shtab=0x175078,
entry=0x100000]
module /boot/vmlinuz-2.6.10-xen0 root=/dev/hda1 ro console=tty
console=ttyS0
[Multiboot-module @ 0x176000, 0x40919c bytes]
=== end ==
with initrd:
=== start ==kernel /boot/xen.gz dom0_mem=64000 com1=115200,n81
[Multiboot-elf, <0x100000:0x3ef7c:0x3536c>, shtab=0x175078,
entry=0x100000]
module /boot/vmlinuz-2.6.10-xen0 root=/dev/hda1 ro console=tty
console=ttyS0
[Multiboot-module @ 0x176000, 0x40919c bytes]
=== end ==
And then the machine reboots automatically. Is my hardware simply
inadequate for xen?
Pentium 200Mhz (P6-class)
64 MB ram
2.0 GB HD
=> It''s just a proof of concept setup to convice our IT manager of
the
benefits.
Does this provide any usefull information?
Thanx in advance,
Regards,
Filip Sergeys

You need to pass com1=115200,8n1 on the "kernel /xen.gz" line and
don''t need the ",115200n8"-part on the "module
/vmlinux..." line.

Do you not see the output from grub? Then you will need to fix that
first. Since you have a working menu.lst for booting the normal
debian kernel, you could start from that and only change the entry.
