Xen users - Sep 2013 - fresh xcp 1.6 & xenserver install fails on first boot (kernel not found).

Hi - I posted the question to the xenserver install forum a couple days ago but
haven''t had any luck (no reply) - then tried xen-api about a day ago,
but I haven''t seen any traffic on that list - I checked the archives to
confirm my message is there - just low low low traffic.

I know this isn''t really the right place (I''m sorry), but
I''m betting (hoping) someone can help and getting more desparate for an
answer.

http://forums.citrix.com/thread.jspa?threadID=337104

I''ve tried XCP 1.6 and the current Xenserver download.

I have installed both xen and xcp several times previously, but this is the
first time I''ve seen this issue.

The install completes as expected, and I''m asked to remove the media
from the dvd drive.

On reboot I get a page of gibberish.  After pressing ENTER a few times I noticed
what I thought was text...

Could not find kernel image: <gibberish and seeming random crud>
boot:

The hardware (I have used similar before) has an intel srcs16 RAID controller -
the controller is detected by the installer - the install seems fine - a rescue
linux disk (centos) can see the installed xcp partition and mount them / read
the files.

Before I realized xenserver / xcp use gpt I thought maybe the issue was a bad
MBR - but that didn''t help.

I can boot into a centos rescue and see the installed partition.

I tried installing xenserver and xcp to a usb stick to see if I was better able
to access the raid array after xenserver / xcp were running - that
didn''t help.

Any idea what I''ve done wrong or need to do to fix is appreciated.
Or is the issue with a non-completely supported controller??

Thank you!

Mitch

I can''t imagine it not booting if the ISO booted just fine.

Errol - thanks!

I saw a post people made about rebuilding initrd (mkinitrd --with-usb) and gave
that a shot.

My backgroud is more freebsd than linux - and that feels rusty. It feels like it
may be the issue (a missing driver) but how do I tell?

Dump dmsg from a shell boot on the xenserver and compare it how?

Thanks again. I tried copying /sys/block/* (I read it in a seemingly related how
to) and ran mkinitrd but that did not help.

Thanks again,

Mitch

I think you might need to be a bit more patient than that, you've given
the forums ~1 working day (posted Thursday evening) and the xen-api list
no working days at all (posted yesterday/Saturday).

That's true - hadn't thought of it in working days tobe honest owing to
how big I'd presumed the community was - with time shifts and so on :-) but
good point. Thanks Ian!

I belive there Is a bug in xcp centos 6.4 were xen.tar.gz is pointing to
wrong folder. I had to correct  menu entry to add /boot If I was you I
would either boot from rescue disk and check that grub2 config file is
pointing to right files and location or edit grub at boot time. I believe
xcp is really  buggy when I played with it there was no way to create lvm
based storage pool.

Do you know what the correct setting is? Presumably i could correct that from
the rescue boot.

I was able to reproduce the issue with the latest xenserver install disk as well
- so I suspect Errol is on the right track - there might be a driver in the
bootable iso which is missing from the installed boot process.

I just need to know how to identify that & fix it.

The intel scrs16 seems to be an lsi megaraid with intel brand.

I can read the installed gpt partition both in xenserver / advanced /shell bot
& other rescue options so it seems to work until the installed bootloader
process tries to access it.

That seems to be where the missing link is?

Thanks!

You stated that the error you are getting is  "Could not find kernel

if you are missing a driver for hard drive controler you would get error
message that states could not find root partition.
look into /boot see what files are there and then edit /boot/grub/grub.cfg

Interesting - I don''t have a grub.cfg
I''ve reinstalled - I still don''t have one. Xcp1.6 and
xenserver produce seem to have the same result.
Is there another location where a backup might be stored? Currently I''m
trying to rebuild one based on what I see from yours, and what I see in the
/boot folder.
I''m not sure how to figure out the root UUID but that''s what
I''m working on.

Thanks Jacek!

I manually build a grub.conf
That didn''t work - not sure if I''m supposed to do something
after editing it, but I couldn''t figure out grubby and found a lot of
people indicating it could simply be edited.

Here is my manually created grub.conf - I used blkid to determine the uuid - I
found the other "id" matched the list in the /etc/fstab

I took your grub.conf and used it to create my missing one.

I found a tool "boot repair disk" and downloaded an iso - it
couldn''t do an "automatic repair" but if provided me the
ability to create a status report.

Here is the tool I used: http://sourceforge.net/p/boot-repair-cd/home/Home/

Here''s the results: http://paste.ubuntu.com/6143774/

But this doesn''t look like I''d expect it to... please take a
look at the results?

Hi again...

I'm pretty sure the missing grub.conf is relevant if not key - though
I'm still sure how to fix it.

The resulting info from theboot-repair-cd seem to point to grub not being
properly installed. But I'm not sure hwo to remedy that.

Thanks again!

Here is the tool I used: http://sourceforge.net/p/boot-repair-cd/home/Home/

Here’s the results: http://paste.ubuntu.com/6143774/

But this doesn’t look like I’d expect it to… please take a look at the results?

You stated that the error you are getting is  "Could not find kernel

error message that states could not find root partition.
look into /boot see what files are there and then edit /boot/grub/grub.cfg
on mine install of centos 6.4 xcp grub.cfg was pointing to / instead of /boot

I was able to reproduce the issue with the latest xenserver install disk as well
- so I suspect Errol is on the right track - there might be a driver in the
bootable iso which is missing from the installed boot process.



I just need to know how to identify that & fix it.



The intel scrs16 seems to be an lsi megaraid with intel brand.



I can read the installed gpt partition both in xenserver / advanced /shell bot
& other rescue options so it seems to work until the installed bootloader
process tries to access it.



That seems to be where the missing link is?



Thanks!

I think you might need to be a bit more patient than that, you've given
the forums ~1 working day (posted Thursday evening) and the xen-api list
no working days at all (posted yesterday/Saturday).

Jacek appears to be using the form of XCP which you can "yum install"
onto an existing CentOS (or Debian with apt) platform. You appear to be
using the XCP "main.iso" style self-contained distro. It is unlikely
that boot problems with one would translate into boot problems with the
other.

IIRC (caveat: I've been nowhere near an XCP of either flavour nor a
XenServer system for years, apply pinch of salt...) the main.iso XCP
uses syslinux (or more precisely extlinux), I expect you'll find a
config file with such a name under /boot somewhere.

You say you've wiped the boot sector -- you might want to try booting a
rescue disk and rerunning extlinux to reinitialise the boot partition
stuff. You might also want to make sure you have a suitable MBR.

http://www.syslinux.org/wiki/index.php/EXTLINUX has more info on both of
those steps.

The other thing which can confuse the boot on a RAID system is a
disparity between what the BIOS sees and what the RAID system makes up.
I don't know if your disk controller is doing hardware or software RAID
but it is something to be aware of e.g. if the BIOS offers a choice of
boot devices including the RAID device and the individual disks, choose
the RAID.

Thanks Ian!
I''ll look into that in the morning.
It is hardware raid - (intel/megaraid) and at install time I can only see the
raid volumes available. Each piece seems to get me closer. Seems to be the same
on xenserver as xcp.
Thanks!

I''m probably several threads behind on this one, but the grub
bootloader is not a part of XenServer/XCP. It uses EXTLINUX
http://www.syslinux.org/wiki/index.php/EXTLINUX
Is your RAID device a fakeraid device?

Nope real raid. 
Scrs16 intel which uses a megaraid driver iirc.
An mentioned that - which would explain why my attemptsto repair grub have been
fruitless
Will be looking at the extlinux config as soon as I get to a desk 

Side question. Xen proper uses xl ? Which is newer than xcp and xenserver?
Xcp won''t be released anymore since xenserver open sourced. So will
xenserver upgrade to the new xen?

Or am I better to roll my own combination as so many of you seem to be doing? (I
guess I''m a slow learner but I can learn ;-) )

Thanks! Will let you know what I see when I look at extlinux config.

It''s not newer, rather it (xl) is orthogonal/alternative to xapi (the

I''m sure XCP/Xenserver will be sticking with xapi, even when they pick

Hi Errol - so I went through the rescue disk boot, mounted /dev/sda1, and once
mounted I looked for /boot/extlinux.conf - and found it - also found a
/boog/extlinux folder with lots of files in it - I wondered if part of the issue
was a bad mbr - I found examples of people initializing the mbr by copying the
mbr.bin from the extlinux or syslinux install.

I don''t see one in the extlinux folders - this is xenserver on the
machine at the moment - but I found /usr/share/syslinux/mbr.bin

So I did:
cp /tmp/sda/usr/share/syslinux/mbr.bin /tmp
umount /tmp/sda
dd if=/tmp/mbr.bin of=/dev/sda

When I rebooted I got a different result.

Missing operating system.

I know that the syslinux mbr file probably isn''t right for the extlinux
in place - so now I''ll try to track down an extlinux mbr file - I
figured it was worth a shot. But I don''t see one in the installed
xenserver. Maybe I''ll find one on the xenserver iso.

Thanks - any more advice / insite appreciated - still wondering if I will get
past this only to find xenserver / xcp are missing a driver or if it''s
really all just about extlinux not installing properly for some reason.

Does anyone know if there is a way from the xenserver or xcp iso to force a
reinstall of extlinux?

Thank you all,

Mitch.

Yes. Reboot back into the XenServer installer. When fully booted, don''t
being the install. Switch virtual terminals then mount the install directory

mkdir /mnt
mount /dev/sda1 /mnt
mount --bind /dev /mnt/dev
mount -t sysfs none /mnt/sys
mount -t proc none /mnt/proc
chroot /mnt /sbin/extlinux --install /boot
dd if=/mnt/usr/share/syslinux/gptmbr.bin of=/dev/sda


See if that fixes it for you.

Ugh! Exact same problem. No missing os message just the gibberish that hides the
no kernel found message.

I''m going to try reinstalling to a single disk on the on board sata
controller while I''m here.

Someone mentioned I should verify the installed kernel had the proper driver in
it (which the iso obviously has as I can mount the file system from it).

Does anyone have any ideas how to do that?

Thanks for the command line errol that made it easy!

Yes. Take the initrd and decompress it:

zcat initrd > /tmp/initrd
Then open it up
mkdir /tmp/initrd_tmp
cd /tmp/initrd_tmp
cpio -idmv < ../initrd

Then examine the files and ensure your driver is there..

I guess I could do this from the cd / iso and compare the results? Or is there a
way to confirm from the working kernel which driver. Is bound to the sda device?

Cpio doesn''t seem to be present.

Looks like there is no cpio in the xcp install disk.

There is a cpiofile python library. But that won''t execute. 

I opted to go back to centos 5.2 (convenient iso) and when I extract initrd I
done see a file containing "megaraid" or mega anything.

I''m going to try to compare the initrd from the xcp disk or the
xenserver disk and see if I can see what''s different.

Then I guess I need to copy the missing driver, recompress the initrd and cross
my fingers?

Thanks!

Will keep plugging away...

I think this is a red-herring.  From the description you have given I
don''t think you are getting anywhere near the point at which the kernel
would want a driver for the hardware. You are failing at the bootloader
stage to even load the kernel in the first place.

Are you able to get a full log of the boot, gibberish and all, perhaps
using a serial console?

Have you validated the content of /boot/extlinux.conf?

There is a console option. Will do. iirc I mentioned seeing a message
"can''t find kernel" followed by a "boot:" buried in
the gibberish. I posted a picture before.

The /boot/extlinux.conf looked ok, and I reinstalled the mbr - changing the mbr
changes the results - but I''ll capture that and post as well.

And when I un pack the initrd I don''t see a file that looks like a
megaraid driver but I haven''t done a thorough search yet. I''d
expect to see one though?

Will go back and do a serial capture later today. 

Thanks :)

I think this is a red-herring.  From the description you have given I
don''t think you are getting anywhere near the point at which the kernel
would want a driver for the hardware. You are failing at the bootloader
stage to even load the kernel in the first place.

Are you able to get a full log of the boot, gibberish and all, perhaps
using a serial console?

Have you validated the content of /boot/extlinux.conf?
