I don't recall any specific guest version dependency.  I've got an old
4.9 guest around and that's about the only direct IGD assignment VM I
test on a semi-regular basis.  I do keep that host relatively updated,
so it's currently a 5.0/4.9 combination.  No reason to keep them in sync
that I know of.  Thanks,

Alex
