Emulated Hardware
Just like running in a non-virtualized computer, a non-paravirtualized guest OS communicates with the hardware as usual. The VMM presents a "device model" to the guest OS, which emulates the hardware. In these illustrations and the one following, the emphasis is on the device drivers. Paravirtualization also refers to modifying the calls to the virtual memory tables.

Paravirtualized Guests
In a paravirtualized OS, the drivers are replaced with calls to the VMM interface. This example shows one VMM model. For more VMM architectures, see virtual machine monitor.
