Upgrading,

    zypper in --force \
     grub2 \
     grub2-branding-upstream \
     grub2-i386-pc \
     grub2-x86_64-efi \
     grub2-x86_64-xen

Notice the "no such file or directory" messages

Checking

    rpm -qa | grep -i grub
        grub2-2.02~beta2-300.2.x86_64
        grub2-branding-upstream-2.02~beta2-300.2.x86_64

        grub2-x86_64-xen-2.02~beta2-300.2.x86_64

Mod'ing the grub config

    EDIT /etc/default/grub
    +    SUSE_CMDLINE_XENEFI=" /mapbs"

Then

    grub2-mkconfig -o /boot/grub2/grub.cfg

Results in

    grep mapbs  /boot/grub2/grub.cfg

        chainloader  $cmdpath/xen-4.6.0_08-405.efi xen-4.6.0_08-405.efi  /mapbs
config.1
                        chainloader  $cmdpath/xen-4.6.0_08-405.efi
xen-4.6.0_08-405.efi  /mapbs config.2

On reboot, no errors on startup. And this error,

    https://bugzilla.suse.com/show_bug.cgi?id=956526#c16

gone as well on subsequent reboot, indicating the " /mapbs" was properly
inserted.
