Bug#912087: openssh-server: Slow startup after the upgrade to 7.9p1

[Ryan Goodfellow]

For people using libvirt, I've found that adding the following to a
domain solves this problem.

    <rng model="virtio">
      <backend model="random">/dev/urandom</backend>
    </rng>

Thanks for the useful pointer in this direction Ted.
