bullshit alert
With a strict technical point of view, all those benefits do not come from hypervisor being type-1 or type-2, this is completely uncorrelated.
A host OS running (only?) a type-2 hypervisor is enough to enable all the benefits depicted.
Running a type-1 hypervisor is mostly a matter of increasing performances of virtual machines. Don't be fooled, the performance i am talking about is only relevant for servers (latency, throughput), not for everyone's personal computer (which is anyway already slowed down by all the bloated software pre-installed).
