We have not been able to try this, but I can't see how it will be different. Looking at what imgexport grabs, I don't see any changes from what I grabbed manually. I tarred up the /install/netboot/rhels6.4/x86_64/compute directory (including the kernel and initrd files). The table definitions all called to the default xCAT compute templates in /opt/xcat/share/xcat/netboot/rh. lsdef on my VM and the cluster MN showed the same information as did lsdef -t osimage rhels6.4-x86_64-netboot-compute.
Considering that I built a default xCAT compute netboot image on the MN and
got the error below, and got the same error from an image built the same
way with the same settings copied over from a fresh install of xCAT, I
don't see how imgexport/imgimport is going to change things unless there's
some special sauce in those commands that I'm not seeing.

If the kernel you're referring to is
in /install/netboot/rhels6.4/x86_64/compute/, then yes I included it. I
tar'ed up that directory. I can try imag{export|import].

You mentioned that the unpatched osimage also did not work on vm, did you
copy the kernel from the build node too? Try the imgexport and imgimport if
you want to build image on another node.
Does this unpatched osimage work in the other cluster like a new xCAT MN
and new xCAT node (bare metal or vm)?
Did you see any dracut error message when running genimage?
Thanks
Best Regards

Subject: Re: [xcat-user] Strange xCAT stateless image behavior
Right, so at first, we upgraded from 2.7.3 to 2.8.3, killed the running
xcatd daemons and ran service xcatd start. Then we used the compute.pkglist
and compute.exlist from /opt/xcat/share/xcat/netboot which didn't work.
Then we used the compute.rhels6.x86_64.pkglist and .exlist. But all of this
was done on a management node that had been patched (including a kernel
patch to 2.6.32-358.18.1), and the updates are not local (it was patched
from a satellite server). I have tried adding a line to
compute.rhels6.x86_64.postinstall "yum --installroot=$IMGROOT update -y"
which applies the kernel patch, but it appears that dracut still wants to
use the base 6.4 kernel (2.6.32-358) to build the initrd. The only times
I've seen errors in building the initrd was the first build (using
compute.pkglist|.exlist which we now know was wrong) and when I included
the yum update in the postinstall script.
Still, it think all of this is actually causing the problem. Last night, I
built a stock 6.4 netboot image using an unpatched 6.4 install on a VM. I
tarred up /install/netboot/rhels6.4/x86_64/compute and uploaded that to the
management node this morning. After booting a system to this image, we
still get the same error:
dracut Warning: Boot has failed. To debug this issue add "rdshell" to the
kernel command line.
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init Not tainted 2.6.32-358.el6.x86_64 #1

? sys_exit_group+0x17/0x20
? system_call_fastpath+0x16/0x
This is the same error we get no matter how we build the image (built on
the MN or on an unpatched VM, applying updates or not). Adding rdshell
returns the same error, but drops me to a shell, and I really don't know
what I'm looking for at that point.
I've also included an lsdef for the node:

Trying to set up the default compute stateless template in v2.8.3 on rhel
6.4. This system was first upgraded from xCAT 2.7.3 to 2.8.3 w/ latest
deps. We took the default compute.pkglist and compute.exlist from
$XCATROOT/share/xcat/netboot/rh. When genimage is building the initrd, I
see the following:

The management node has a patched kernel, and it appears the stateless
image is running the stock rhel 6.4 kernel. Could this be the problem, or
am I missing something:
