Virtio rng is a paravirtualized random number generator device, it provides a hardware rng device to the guest.

Only two property is supported for virtio-rng.
|

|
|
* random_file: the path of character device generates with random number in host

* bytes_per_sec: the number of bytes that the character device generates with a random number per second,
