Which two are characteristics of block I/O in a fully hardware virtualized configuration?

The virtual machine I/O path only uses the block device driver from dom0.

The virtual machine relies onemulation of the hardware in dom0 for block I/O.

The virtual machine I/O path includes the native block device drivers from the guest operatingsystem.

The virtual machine does not need a block device driver.

The virtual machine must provide emulation of the hardware through its own IOEMU drivers.
