Looks like the root cause of the problem was this:

Rebuilding grub2-bhyve-0.40_11 from source fixed the problem.

I have tracked this down to https://reviews.freebsd.org/D44565

Adding COMPAT_FREEBSD14 to the kernel and/or rebuilding grub-bhyve with 
libvmmapi.so.7
fixes the problem.

It would be great if this ABI change got documented in RELNOTES/UPDATING, thank 
you...
