This is a very old release (4 to 5 years old) and it is not supported anymore.

Since this was written it could really be that Renesas updated their support so 
you might try to check an newer version of the gen3 support:
https://elinux.org/R-Car/Boards/Yocto-Gen3/v4.7.0

and use the corresponding version of meta-virtualization.

There are some patches for pygrub on meta-virtualization master that you might 
want to look at:
https://git.yoctoproject.org/cgit/cgit.cgi/meta-virtualization/tree/recipes-extended/xen/files/0001-python-pygrub-pass-DISTUTILS-xen-4.14.patch
