Public bug reported:
According to https://wiki.qemu.org/Features/VirtIORNG the default
backend for `virtio-rng-pci` is `/dev/random`. 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.
