Comment 12 for bug 692691

This is not a Xen-only issue as qemu-kvm is also affected.

My current work-around is to use OpsCode Chef to detect if grub1 in installed and replace /usr/sbin/update-grub with a working version.

* QEMU guest environment:

$ lsb_release -sd
Ubuntu 10.04.3 LTS

$ uname -srv
Linux 2.6.38-11-server #50~lucid1-Ubuntu SMP Tue Sep 13 22:10:53 UTC 2011

$ cat /boot/grub/device.map
(fd0) /dev/fd0
(hd0) /dev/vda

$ dpkg -l | awk '/grub/ {print $2 " " $3}'
grub 0.97-29ubuntu60.10.04.1
grub-common 1.98-1ubuntu12

* Before replacing /usr/sbin/grub-update

$ sudo update-grub
