Public bug reported:

This is more of a feature request than a bug.

Please include the virtio-rng hw_random module in the -virtual kernel
package along with the other virtio drivers.

Virtual machines often do not have much of hardware randomness
available. This can negatively affect performance of cryptographic
operations (HTTPS/TLS handshakes, SSH connections, running GPG etc.) as
well as simple things such as opening TCP connections.

This virtio driver solves the problem with QEMU/KVM by providing
randomness available in the host machine to the guests which have this
driver loaded. This is then used to seed /dev/random.

This module seems to be currently available in the -generic and -server
packages (where it is not really needed).

** Affects: linux (Ubuntu)
