Accepted Answer

With paravirtualization, the guest OS can be made aware of the VMM (Virtual Machine Monitor) and invoke it directly for special functions.

Answer

With VT-x, there is no support for paravirtualization.

Answer

No response (no penalty if only option answered).

Answer

With VT-x, the scheduling of guest VMs no longer requires executing VMM code between one guest VM losing the CPU and another one entering execution.

Answer

With paravirtualization, the guest OS is offered a standard interface to VMM services and can easily switch to another VMM.
