Now that you're really using the SVM emulation, please bear in mind that the upper SVM exits don't work due to the 64-bit int limits. I haven't really found a proper solution for that, but in the meantime you can't intercept instructions like MONITOR or WBINVD, as they get shifted out of the TB identifier.

Just so you know.

This one is really important as it makes current kvm versions run. Please apply.
