virtio-rnd is implemented as a virtio legacy device in the ACRN Device
Model (DM), and is registered as a PCI virtio device to the guest OS
(User VM). Tools such as :command:`od` (dump a file in octal or other format) can
be used to read random values from ``/dev/random``. This device file in the
User VM is bound with the frontend virtio-rng driver. (The guest kernel must
be built with ``CONFIG_HW_RANDOM_VIRTIO=y``). The backend
virtio-rnd reads the HW random value from ``/dev/random`` in the SOS and sends
them to the frontend.
