[Bug 589108] [NEW] pae kernel installed by kvm will not boot

[Ralph Green]

Public bug reported:

Binary package hint: qemu-kvm

I am running an AMD-64 system with 32 bit kernel and all updates as of today for Release 10.04.  I have 2 GB of ram and I installed kvm and a couple of related tools today.  My hard drive is laid out like this.
  sda1 - /boot ext2
  sda2 - encrypted swap
  sda3 - /usr xfs
  sda5 - / xfs
  sda6 - /public xfs

 Installing kvm caused a new kernel to be installed and grub.cfg was modified to make the new kernel the default.  The menu entry for the new kernel describes it as: Ubuntu, with Linux 2.6.32-22-generic-pae.  These 3 lines in grub.cfg(last part is munged because I don't know if this is sensitive) were also edited:
- - It used to say- - - - -
insmod ext2
set root='(hd0,1)'
search --no-floppy --fs-uuid --set eab686fd-b09a-4386-bb51-xxxxxxxxx
- - It now says- - - - -
insmod xfs
set root='(hd0,3)'
search --no-floppy --fs-uuid --set 83428bb0-2072-4330-b0a5-xxxxxxxxx

 When the computer boots this kernel, it stop and says "uuid=c239b85b-
fbd4-4d6e-9524-xxxxxxx does not exist. Dropping to shell!" and I get an
initramfs prompt.  That is the uuid of /dev/sda5, which is the root
partition.  I edited grub.cfg to fix the 3 lines, and put /dev/sda5 on
the kernel line and now I get  "/dev/sda5 does not exist. Dropping to
shell!"

 I then edited the default to make it boot my old kernel and the system
comes up fine.

 I found the bug when installing kvm, but I don't know if that is the
right package to report this under.  It may be the kernel, and so I
specified the kernel above.
