There's two possible ways to approach this: (1) Use a guestfish command like: sh "grub-install [...]" (2) Forget about grub, and use extlinux: https://rwmj.wordpress.com/2013/04/04/new-in-libguestfs-use-syslinux-or-extlinux-to-make-bootable-guests/#content Unfortunately the grub-install API, while nice to use, only works for grub1, and that is now obsolete.
