  This was fixed in grub2-bhyve upstream with
 
https://github.com/grehan-freebsd/grub2-bhyve/commit/370fa455d41212282bf63cea7b048e87a821a31a

  I'm gathering a few more fixes before doing a point release of 
grub2-bhyve, at which point the FreeBSD port will be updated.

  You'll need to do a 'bhyvectl --destroy' until then, or build 
grub2-bhyve from upstream.

later,

Peter.
