finally I've managed to test both physical PowewNV hardware and a KVM
guest and the is no problem in the installer. KVM guest installation
works as before. The bare metal PowerNV one prints a error during the
"bootloader installation" phase, but succeeds anyway. The problem is
in grub due
"grub2-install: error: the chosen partition is not a PReP partition."
which will need fixing there by loosening that requirement.
I think I have a solution for this problem as well. There is already a
request to loosen the check in grub2 , but IMHO a more appropriate
solution is to skip installing the grub binaries in anaconda and let
anaconda write only the grub config. Which could be achieved by
introducing of a PowerNVGRUB2 class with an empty install() method.
