I think the cause of this was actually a generic grub/anaconda issue -
I'm sure I've seen other reports of grub failing with F11 virt preview.
I think it's been known to hang in the "installing bootloader" installer
step? I can't find any references now, anyone else seen it?

With the fix (i.e. grub-0.97-50.fc11) for:


the following works for me:

  $> grub-install /dev/vda1

with "(hd0) /dev/vda" in /boot/grub/device.map

you need to actually pass it the device map:

  $> grub --device-map=/boot/grub/device.map
  grub> root (hd0,0)
  setup --prefix=/grub (hd0)
