Breakthrough? VT-d and API forwarding are old hats, the former doesn't 
allow any kind of sharing which means it's out for most of the users, 
and API forwarding is already available.

The GVT-g approach is so far not known to be feasible in a type 2 
hypervisor, so only a thorough analysis of the truth behind the press 
digestable message will tell if this is more than hot air for VirtualBox.

It's still a giant amount of work, as when Intel says "support nested 
virtualization" it always implies that a lot still needs to be done in 
software.
