Interesting, especially reducing the effort for the maintainance.
For the performance, we still have some tasks(NUMA, VTd...)
But reducing the maintainance efforts is great.
Is the reason that VT-dom0 can use the same privilegde operation
as native kernel? We maintain just PV driver and some firmware codes?
