Well to be fair to Microsoft, the only reason SuSE driver would even
load on RHEL is if the virtio devices running on SuSE look to Windows
sufficiently like the virtio devices running on RHEL.  It's not the
normal thing to have two completely different vendors writing drivers
for nearly identical (yet incompatible) hardware, so it's not terribly
surprising that they didn't start out with checks for this kind of
thing.
