I believe I just tripped this bug; I compressed some qcow2 images using this:

for f in sec-{lucid,precise,quantal,saucy,trusty}-{amd64,i386} ;
  do echo $f ;
  qemu-img convert -s pristine -p -f qcow2 -O qcow2 $f.qcow2 reclaimed.qcow2 ;
  mv reclaimed.qcow2 $f.qcow2 ;
  virsh snapshot-delete $f --snapshotname pristine ;
  uvt snapshot $f ;
done

The 'uvt snapshot' command makes a snapshot named 'pristine'.

AMD64 guests:
sec-lucid-amd64 booted without trouble.

sec-precise-amd64 reports:
Booting from Hard Disk...
Boot failed: not a booktable disk

No bootable device.

sec-quantal-amd64 reports:
Booting from Hard Disk...
error; file `/boot/grub/i386-pc/normal.mod' not found.

sec-saucy-amd64 reports:
Booting from Hard Disk...
error: file `/boot/grub/i386-pc/normal.mod' not found.

grub rescue>

sec-trusty-amd64 reports:
Booting from Hard Disk...
Boot failed: not a bootable disk

No bootable device.

i386 guests:

sec-lucid-i386, sec-precise-i386, sec-quantal-i386, sec-saucy-i386 all booted fine.

sec-trusty-i386 reports:
Booting from Hard Disk...
Boot failed: not a bootable disk

No bootable device.

I use the i386 VMs significantly less often than the amd64 VMs.
