Petro,
That did not change anything. I still can’t figure out where Cobbler
is configure to tell the system to look for /boot.cfg. If I can get
past that, I can complete this task.
There's at 4 different systems or packages interacting here. DHCP, TFTP,
PXE. My bet at this point is that Cobbler isn't doing anything (whether
it should or not I'm not sure. I think most of these files are outside
of cobbler control. The Cobbler Devs can certainly tell me I'm wrong).
This is from your first email (or at least the first email I've seen):

What happens here is that the pxeboot stuff on your physical host is
making a request for "pxelinux.0" which loads and runs. Pxelinux.0 then
starts making requests for
pxelinux.cfg/40867f18-bb4b-df11-93ef-8843e1c2b2e8 and then
pxelinux.cfg/01-88-43-e1-c2-b2-ee. It finds
pxelinux.cfg/01-88-43-e1-c2-b2-ee which is a configuration file which
originally had:

When mboot.c32 runs it makes a request for "/boot.cfg". I suspect that
something in pxelinux.cfg/01-88-43-e1-c2-b2-ee isn't quite right and the
"-c images/ESX-5.0-x86_64/boot.cfg" isn't getting passed properly.
We changed the images/ESX-5.0-x86_64/boot.cfg file to look like:
default linux
prompt 0
timeout 1
label linux
kernel images/ESX-5.0-x86_64/mboot.c32
ipappend 2
append -c images/ESX-5.0-x86_64/boot.cfg
right? But it's still looking for /boot.cfg.
What happens if you do:
label linux
kernel images/ESX-5.0-x86_64/mboot.c32
append -c images/ESX-5.0-x86_64/boot.cfg
And if that works, stick the ipappend 2 back in and see if that breaks
it again.
What does your DHCP config look like for this group?
On a side note I was able to get this to work by a few manual steps.
1.) Copy the boot.cfg from the
/var/lib/tftpboot/images/ESX-5.0-x86_64 directory to the /var/lib/tftpboot
Yeah, that doesn't surprise me.
2.) Manually copy all files from
/var/www/cobbler/ks_mirror/ESX-5.0-x86_64
to /var/lib/tftpboot/images/ESX-5.0-x86_64
I think I can fix #2 by listing out each file explicitly in the
TFTP_boot files for the distro instead of asking for *.* which causes
the copy failure on an existing file (kernel and initrd specified in
the distro).
I haven't got that far in Cobbler, but "*.*" is a windows thing and will
*only* match files that have a "." in them. If you do a "ls *.* | wc -l"
in that directory and then do a "ls * | wc -l" you'll find a very
different number. Any file that doesn't have an extension won't get copied.
If you do a "*" you should get everything.
However I have no idea how to really fix #1. :(
I was working on that first.
Just to see if it changes something try:
default linux
prompt 0
timeout 1
label linux
kernel images/ESX-5.0-x86_64/mboot.c32
ipappend 2
append -c images/ESX-5.0-x86_64/boot.cfg
**just** that and see if it gets further.
Note also relative paths.
And make sure boot.cfg

I even tried adding the line:
append -c /images/ESX-5.0-x86_64/boot.cfg
Which made no difference, still searching for //boot.cfg.
This is what I’m seeing while running cobbler sync, towards the end
of the run.

Petro,
Thank you for the quick response.
I’m wondering why this is the case. I am only using the default options for
tftp and cobbler in this regard. Something must be instructing the system to
look for /boot.cfg instead of /images/ESX-5.0-x86_64/.
I can't really answer that, sorry. It's been a *long* time since
I've been that deep in PXE booting/TFTP, and I haven't done cobbler
with TFTP, and I haven't used either for ESX.
I suspect that something in the ESX process is looking for the
boot.cfg. My best guess is something in menu.
This might help:

Note these bits in particular:

> /tftpboot/pxe/esxi-5.1.0u1-1065491/boot.cfg
and

Why would the cobbler templates not generate the boot.cfg in the proper
location if it is infact in the tftpboot directory and not in the distro
directory? I would imagine if you had more than one ESX distro you would then
have collisions on the boot.cfg. I think something else is at play here.
Also how do I get the system to properly copy all the boot files to the tftp
directory when running cobbler sync?
What happens right now when you run cobbler sync?
The top few lines of my output are:

But this is a non-production "I'm just playing with it" environment
that I started setting up last week, so I haven't really dug into
it yet, and since my soon to be future employer doesn't use it, it
might get blown away.
Regards,
Petro.
