libvirt won't have such a simple command line.  There could be other
KVM options which affect things at boot.

I have a couple of suggestions:

(1) Find out the full libvirt command line.  Easiest is to start the
domain under virt-manager and quickly use the 'ps ax' command.  (There
is a more "official" way to convert libvirt XML into a qemu command
line but I cannot recall what that is at the moment).

(2) Use virt-rescue or guestfish and see if you can install grub in
the domain.  In guestfish it'd be something like this:

  guestfish -i GuestName
  ><fs> mkdir-p /boot/grub
  ><fs> grub-install /boot /dev/sda1

(You might need to change those command slightly and read the man page
for virt-rescue, guestfish and/or grub-install).
