no, XEN stays here at BSD! 
bhyve is this fast as tmc!

this is the output for information purpose:

"Intel® Virtualization Technology for Directed I/O (VT-d) continues from the 
existing support for IA-32 (VT-x) and Itanium® processor (VT-i) virtualization 
adding new support for I/O-device virtualization. Intel VT-d can help end 
users improve security and reliability of the systems and also improve 
performance of I/O devices in virtualized environments."

aeh! bulls*! but pitty, pitty, you can't request from an 7 year old machine 
everything you want. so heaven stays cloudy but RAPTOR9 willl do? no troubles 
with (U)EFI there?
