I am virtualizing some machines from Dell 2950s running RHEL5 to ESX 3 using my own script running on Kanotix (a Knoppix 64-bit variant).

I have a script that builds and copies the data, but I need to rebuild the kernel due to device changes.

chroot /mnt/sysimage/root/mkinitrd fails. It is an edited copy of mkinitrd. In attempting to debug this problem, I find that chroot /mnt/sysimage fails also.

I do the following:
vgscan --mknodes
vgchange -ay
lvscan
mkdir /mnt/sysimage
mount /dev/VG00/LVroot /mnt/sysimage
mkdir /mnt/sysimage
mount /dev/VG00/LVroot /mnt/sysimage
mount -o remount,dev,exec,data=ordered /dev/VG00/LVroot /mnt/sysimage
mount -o exec,data=ordered /dev/sda1 /mnt/sysimage/boot
mount -o exec,data=ordered /dev/VG00/LVtmp /mnt/sysimage/tmp
mount -o exec,data=ordered /dev/VG00/LVusr /mnt/sysimage/usr
mount -o exec,data=ordered /dev/VG00/LVvar /mnt/sysimage/var
mount -o exec,data=ordered /dev/VG00/LVopt /mnt/sysimage/opt
mount -o exec,data=ordered /dev/VG00/LVoradata /mnt/sysimage/oradata
mount --bind /proc /mnt/sysimage/proc
mount --bind /sys /mnt/sysimage/sys
mount --bind /dev /mnt/sysimage/dev
mount --bind /dev/pts /mnt/sysimage/dev/pts

and then
chroot /mnt/sysimage

this gives
chroot: cannot run command `/bin/bash': Exec format error

also
/mnt/sysimage/bin/bash gives the message
chroot: cannot run command `/bin/bash': Exec format error

uname -a on the real machine gives

uname -a on the Kanotix guest gives

file /mnt/sysimage/bin/bash gives

and for reference,
file /bin/bash gives
/bin/bash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.4.1, dynamically linked (uses shared libs), for GNU/Linux 2.4.1, stripped

the pertinent section of mount shows

ls -al /mnt/sysimage/bin/bash gives

I have tried all kinds of things to get this to work. I've used a couple of other Knoppix64- and Knoppix-type distros. I've done all kinds of Google searches. Somehow I'm guessing these just won't run the bash off of the target sysem due to architecture differences.

Any suggestions?
