Hi Andy,
thanks for the reply.
OK, so I purged all the xen-related packages and configs, and installed grub-legacy and linux-image-686-pae. dpkg-query -l |grep xen returns nothing
/boot/grub/menu.lst looks OK, but to be safe I backed it up and generated a new one with update-grub, and zeroed out /boot/grub2/grub.cfg
still, same problem when I drop back into console, destroy the running instance, and try to boot.
Using config file "/etc/xen/travelkazoo.conf”.
Error: Boot loader didn't return any data!
Here are the non-default entries in /boot/grub/menu.lst:
title Debian GNU/Linux, kernel 3.2.0-4-686-pae
root
kernel /boot/vmlinuz-3.2.0-4-686-pae root= ro
initrd /boot/initrd.img-3.2.0-4-686-pae
title Debian GNU/Linux, kernel 3.2.0-4-686-pae (single-user mode)
root
kernel /boot/vmlinuz-3.2.0-4-686-pae root= ro single
initrd /boot/initrd.img-3.2.0-4-686-pae
Anything else you can suggest for me to try?
Best,
-John

I’ve been searching like mad and can’t seem to find anything else to try.
