From 16c915ba42b45df7a64a6908287f03bfa3764bed Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Wed, 20 Jun 2012 12:29:32 +0530 Subject: virtio-rng: hardware random number generator device The Linux kernel already has a virtio-rng driver, this is the device implementation. When the guest asks for entropy from the virtio hwrng, it puts a buffer in the vq. We then put entropy into that buffer, and push it back to the guest.
