  # walk through install with all defaults

  install fails at grub stage.

  I chose defaults for disk setup (lvm) and the chose 'install grub to MBR'.
  The error message is:

  --
  Install the GRUB boot loader on a hard disk
        Unable to intsal GRUB in /dev/vda5
    Executing 'grub-install /dev/vda5' failed.
  This is a fatal error.
