Subject: [PATCH 1/2] rngd: add udev rule to source from hwrng if virtio-rng present
Date: Thu, 7 Aug 2014 18:38:59 +0530 [thread overview]
Message-ID: <dd2ddb8458e5ab5cffceb7fac2e3f71e9e2197f3.1407416628.git.amit.shah@redhat.com> (raw)
In-Reply-To: <cover.1407416628.git.amit.shah@redhat.com>
In-Reply-To: <cover.1407416628.git.amit.shah@redhat.com>
On KVM guests where the virtio-rng device is available, and set as the
current rng, this udev rule will start rngd which will feed in the
host-provided entropy to /dev/random.
