I have suspision that it is very close to the bhyve checkin:

------------------------------------------------------------------------
r245652 | neel | 2013-01-19 08:18:52 +0400 (сб, 19 янв 2013) | 9 lines

Merge projects/bhyve to head.

'bhyve' was developed by grehan@ and myself at NetApp (thanks!).

Special thanks to Peter Snyder, Joe Caradonna and Michael Dexter for their
support and encouragement.

Obtained from:  NetApp

------------------------------------------------------------------------

since this is the code that started to utilize VT-x.

Can you please check this revision and -1 revision to it?
