Re: [Xen-users] fresh xcp 1.6 & xenserver install fails on first boot (kernel not found).



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!

M

I manually build a grub.conf

That didnât work â not sure if Iâm supposed to do something after editing it, but I couldnât figure out grubby and found a lot of people indicating it could simply be edited.

 

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

 

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

 

multiboot /boot/xen-4.1.5.gz dom0_mem=1024M,max:1024M loglvl=all guest_loglvl=all elevator=noop iommu=0 cpufreq=dom0-kernel cpuidle

module /boot/vmlinuz-2.6-xen root=UUID=45f8b3d8-cb27-46f1-be49-2e56766faf5f ro iommu=no-intremap  quiet

module /boot/initrd-2.6-xen.img

 

I found a tool âboot repair diskâ and downloaded an iso â it couldnât do an âautomatic repairâ 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/

 

Hereâs the results: http://paste.ubuntu.com/6143774/

 

But this doesnât look like Iâd expect it toâ please take a look at the results?

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

on mine install of centos 6.4 xcp grub.cfg was pointing to / instead of /boot 

Mine grub.cfg is 

    multiboot /boot/xen-4.4-unstable.gz dom0_mem=1024M,max:1024M loglvl=all guest_loglvl=all elevator=noop iommu=0 cpufreq=dom0-kernel cpuidle

    module /boot/vmlinuz-linux-xen  root=UUID=4f7314c5-fa15-4b3e-9c37-2543f9f26ab6 ro  iommu=no-intremap  quiet

    module /boot/initramfs-linux-xen.img

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!

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.

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 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).

Ian.
