Public bug reported:
After I upgrade one of my xen pvm ubnutu 13.10 installations to 14.04, I was
not able to boot them any more on my ubutntu 12.04 dom0. Starting them results
in following mesage:
sudo xm create /etc/xen/lisa.cfg
Boot loader didn’t return any data!
Within /var/log/xen/xend.log I found the following messages:

After some time of try and error I also found a workaround for this
issue, by removing the grub2 packages and installing the god old grub
package within a chroot, as described here: http://0x23.de/2012/05/xen-
ubuntu-12-04-upgrade-boot-loader-didnt-return-any-data/
