This is the /etc/xen/anya_zanet config:


kernel = "/boot/vmlinuz-2.6.23.1-42.fc8"
ramdisk = "/boot/initrd-2.6.23.1-42.fc8.img"

You are trying to boot off of a non-xen kernel. Fedora xen kernels would look something like vmlinuz-2.6.21.7-3.fc8xen. Also, at some time, you will probably want to switch over to pygrub, to boot off of the ubuntu kernel on your image.

Hi Jim,

I now have the following config:

cat /etc/xen/anya
bootloader = '/usr/bin/pygrub'
memory = 512
name = "anya"
disk = ['phy:/dev/backup/anya,ioemu:hda1,w']
vif = [ '' ]



But I still get the same error:

xm create anya
Using config file "/etc/xen/anya".
Error: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader found\n')



So, I presume I don't have the right kernels for Ubuntu, yet they are there:
ll boot/

So, what else can I do?
