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?

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 Call Trace: ? panic+0xa7/0x16f ? do_exit+0x862/0x870 ? fput+0x25/0x30 ? do_group_exit+0x58/0xd0 ? 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.
