  So, I'm experimenting with setting up templated DomUs using Xen, and I wanted 
to try out
some of the Jailtime.org images, so I grabbed an Ubuntu 8.04 LTS 32-bit image.

  It supplies an image and a config file (which I tweaked for the location of 
the .img):

-rw-r--r-- 1 root root 1049624576 2008-07-16 22:39 

kernel = "/boot/vmlinuz-2.6-xen"
memory = "256"
name = "ubuntu.8-04"
vif = ['']
dhcp = "dhcp"
disk = ['file:/etc/xen/images/ubuntu.8-04.64.img,sda1,w']
root = "/dev/sda1 ro"

  When I try to boot it:

 xm create /etc/xen/configs/ubuntu.8-04.64.xen3.cfg -c
Using config file "/etc/xen/configs/ubuntu.8-04.64.xen3.cfg".
Error: Kernel image does not exist: /boot/vmlinuz-2.6-xen

  Ok, so this comes down to an issue I don't quite understand -- the 
bootstrapping the
DomU guest kernel. Here the config says it's /boot/vmlinuz-2.6-xen

  Well, if I mount the image and look into it, there's nothing in /boot at all.

  Is this referring to a kernel in my Dom0's /boot? This wouldn't seem to make 
sense, as
you might have dozens of different DomUs of different varieties and versions of 
Linux, and
they could fight with each other in the Dom0's /boot namespace.

  So, what namespace exactly is the kernel line referring to, and why isn't the 
image happy about it?

  I ran into the same issue trying to use the ttylinux image from here:

  What should the kernel line read? Obviously "/boot/..." is a stand-in, but 
for what?

  Thanks in advance. I'm just missing this critical nugget of understanding.
