Feel free to send some patches to implement this! Alternatively, you could also try to write a mail to the virtio-rng maintainer (see the MAINTAINER file in the top directory of the sources), maybe he can help.

Alternately, the user can point it to a different backend file, like `/dev/urandom`. However, both of these files have suboptimal behavior in one way or another, as documented in `random(7)`. Instead, the default behavior should be to pull the requested octets from the `getrandom()` system call, if available, called with no flags set.
