Thanks this is excellent information, and definitely puts me on the track.

Does this seem at all, unusual, to you? To me it sounds like it was by
design, but it is clearly buggy (from the perspective of those of us
trying to use hardware virtualization on machines which have this
problem). I wonder if this is going to change at some point.

In any case, I will take your advice and try to patch grub to see if
it fixes my problem. Will post an update here with my progress.


Thanks again,
Chuck
