This is verified OK.

Rolf installed a Power system w/ PowerKVM in one disk, then installed Ubuntu Xenial in another disk, then installed grub2 packages from xenial-proposed.

The comparison of grub.cfg files before/after shows that the entries to boot PowerKVM in the other disk are no longer present (only present in the .orig file, as shown in the diff below).

$ diff /boot/grub/grub.cfg /boot/grub/grub.cfg.orig|grep menuentry
> menuentry 'unknown Linux distribution (on /dev/mapper/ibmpkvm_vg_root-ibmpkvm_lv_system)' --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-simple-7a7bdea5-29ac-4b23-86a6-2cd6f9c510b0' {

And this is the Petitboot screen.
No extra entries to boot PowerKVM other than its own.
