Xen users - Dec 2008 - Installation Problem: exec of init (/sbin/init) failed!!!: No such file or directory

Hi folks:

I''m having the exact problem with /sbin/init described at
http://lists.xensource.com/archives/html/xen-users/2007-04/msg00570.html
The environment is CentOS but the problem and the steps I''ve taken are
exactly the same.

The guest''s fstab is

dev/sda10       /               ext3    defaults        1 1
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=SWAP-sda2         swap                    swap    defaults        0 0


My config script is

kernel = "/boot/vmlinuz-2.6.18-92.1.18.el5xen"
ramdisk = "/boot/2.6.18-92.1.18.el5xen-custom-3"
memory = 256
name = "ExampleDomain"
vif = [ '''' ]
disk = [ ''tap:aio:/home/admin/vm1disk,sda10,w'', ]
root = "/dev/sda10 rw"
extra = "4"

The error log is attached..

Thanks for your help
Manu

That thread is somewhat hard to follow, but the suggestions seem good.

The basic idea is that you have a guest on a different partition and you
are trying to boot it?

The guest was/is a normal linux install?


Are you just missing a forward slash in the fstab below?
(/dev/sda10)? or is that just a typo?

Do make sure that everything is in the right spot...

chroot in the the partition for example.

Is it bootable as a normal linux system with grub
(not as a xen guest, just to test)?

don''t put the rw in the root line.
root="/dev/sda10"

and



Try it instead in the extra
extra="ro 4"


Hope that helps.

Cheers,
Todd

Hey Todd:

That missing / was a typo.
I re-generated the initrd file anyways and it still fails with the same
error.

The only thing that I''m doing differently is that I created a new
device
file /dev/sda10 for the guest
However the linux kernel is the same as the one that DomU is using.

I cannot reboot the system to check out whether the boot loader will be able
to load the new image.
I''ll try that tomorrow.
I''m playing with some centos specific install programs (virt-install,
virt-image etc) in the meantime..

Thanks for your help
