any word on this?  If this is not considered for adoption, i would like
to know the reason, so that we can have better predictions about what to
do for entropy in a QEMU system.

Title:
  virtio-rng backend should use getentropy() syscall when available

Status in QEMU:
  New

Bug description:
  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.
