Yunfeng,

Good news is that I can't reproduce the problem with kvm.tip as of
today. Both Win XP and Win 2000 Server boot happily (note: before those
fixes 2000 would crash complaining about PFN list corruption) and all of
their memory is mapped with 2MB pagetables.

Bad news is that I can't reproduce the problem at all anymore, so its
hard to pinpoint which change fixed it (assuming the bug is actually
fixed).

So, since there have been two important hugetlb fixes since
ff5bdac4be0230e0bb33e4208ac0a91343c72929, it would be good if you can
try a recent kvm.tip on the host.
