The error of "ELF image has no shstrtab" happens
when you try to get paravirtualized xen to boot a non-Xen kernel
which was the default kernel in grub.conf.
Now trying to figure out what is wrong with the vmlinuz/initrd
combo of my actual Xen kernel.

----------------------
My question is the following--it looks like from the dump below, the
xen is trying to boot with a kernel and ramdisk in dom0
even though I specified bootloader=/usr/bin/pygrub and wanted
it to take the xen kernel from inside the image. Are there
other things I need to do to make that happen? I am presuming
that if I specify a KERNEL= and RAMDISK= in the template
then it will try to find those kernel and ramdisk in dom0.
These are the relevant entries from my template
OS = [ bootloader = "/usr/bin/pygrub" ]
DISK = [ image = "cloudmysql-hybrid" ]

Docs show that I need the "bootloader" option in the OS section.
Adding that got me past the error mentioned below.

------------
My OS image has a kernel-xen loaded in it but is otherwise
the same format as the KVM images I have been using,
i.e. it has a boot sector and one partition which is supposed to mount
as /dev/sda1.
As far as I can tell, I never got as far as trying to launch the
Xen VM.
