The lowest 3 bits of the segment selector is a tag which indicates some
properties of the segment (iirc).  111b means a LDT selector, and that's
what the above assertion tests.   I think you've probably hit a 
GDT selector (011b iirc).

But anyway, as Tom says, R H 8.1 contains NPTL, which V can't emulate
well enough to be useful, and we don't have an ETA on fixing it either.
Best advice is to avoid 8.1 if you want to use V.  At least for the
moment.
