Title:
  update-grub thinks my kernel is a xen one

Status in “grub” package in Ubuntu:
  Fix Released
Status in “grub” source package in Lucid:
  Triaged
Status in “grub” source package in Natty:
  Fix Released

Bug description:
  SRU justification:
  The version of grub included in lucid has code for detecting Xen-only kernels which misfires on later kernel releases, where Xen guest support may be built into a kernel that can also be run on bare hardware.  The distro kernels for natty and later are built in precisely this way, which means that the LTS backport kernels for natty and oneiric are also built this way - making it impossible to use these backported kernels on a 10.04 LTS system that's using grub 1 as its bootloader.

  Test case:
  1. Configure 10.04 LTS with grub as its bootloader.
  2. Install the linux-image-server-lts-backport-oneiric package.  Observe that the newly installed kernel is ignored by update-grub as in the below messages.
  3. Install the grub package from lucid-proposed.  Observe that the 3.0.0 kernel is no longer ignored by update-grub.

  Binary package hint: grub

  I noticed I'm not running that latest kernel and it seems that update-
  grub doesn't like the newest ones I have available.
