"broken" domU config:

#kernel = "/boot/vmlinuz-2.6-xenU"
kernel = "/boot/vmlinuz-2.6.16-1.2080_FC5xenU"
ramdisk= "/boot/initrd-1.6.16-1.2080_FC5xenU.img"
memory = 128
name = "fedora.fc5"
#nics = 1
vif = [ '' ]
dhcp = "dhcp"
disk = ['file:/var/xen/xen-get-fedora/fedora.fc5.img,sda1,w', 
'file:/var/xen/xen-get-fedora/fedora.swap,sda2,w']
root = "/dev/sda1 ro"

#bootloader="/usr/bin/pygrub"


like this, I get:

Using config file "/etc/xen/xen-get-fedora".
Error: Error creating domain: Kernel image does not exist:

When I remove the comment before the bootloader line, I get:

Using config file "/etc/xen/xen-get-fedora".
Traceback (most recent call last):
   File "/usr/bin/pygrub", line 256, in ?
     cf = get_config(file, isconfig)

     return Ext2Fs(fn, offset = offset)

Error: Boot loader didn't return any data!


The working config generated by the fedora5 script described in the wiki 
looks like:

# Automatically generated xen config file
name = "fedora-simple"
memory = "256"
disk = [ 'file:/var/xen/fedora-simple,xvda,w' ]
vif = [ 'mac=00:16:3e:16:03:83' ]
bootloader="/usr/bin/pygrub"

on_reboot   = 'restart'
on_crash    = 'restart'

I'll see if I can try the same with a jailtime image instead. This can 
take a while because the hardware I had for testing will not be 
available much longer.
