  • Support for the VirtIO RNG device has been added to the QEMU sources starting from commit a9b7b2ad7b075dba5495271706670e5c6b1304bc. This is part of the QEMU 1.3 release. The Linux kernel contains the guest driver for the device since version 2.6.26.

Detailed Description

VirtIO RNG is a paravirtualized device that is exposed as a hardware RNG device to the guest. On the host side, it can be wired up to one of several sources of entropy, including a real hardware RNG device as well as the host's /dev/random if hardware support doesn't exist.
