Starting rng-tools in SLES guest in VirtualBox
Clash Royale CLAN TAG#URR8PPP
I am trying to start rng-tools in a SLES 11 SP3 installation inside of VirtualBox.
vagrant@sles11sp3x64:~> uname -a
Linux sles11sp3x64 3.0.93-0.8-default #1 SMP Tue Aug 27 08:44:18 UTC 2013 (70ed288) x86_64 x86_64 x86_64 GNU/Linux
All attempts have been un-successful, with the following output:
vagrant@sles11sp3x64:/etc/init.d> sudo /sbin/service rng-tools status
Checking for RNG daemon unused
vagrant@sles11sp3x64:/etc/init.d> sudo /sbin/service rng-tools start
Starting RNG daemon No Hardware RNG support available skipped
here is the contents of /etc/default/rng-tools :
vagrant@sles11sp3x64:~> cat /etc/default/rng-tools
HRNGDEVICE=/dev/urandom
What am I missing to get VirtualBox to expose my hardware correctly?
linux virtualbox virtual-machine random

What exactly do you expect should happen? In a VM there usually are no HWRNGs. Clarify please.

@peterph For a VM, the “hardware RNG” is the RNG of the host.
– Gilles

@Gilles not really - you would have to emulate the HWRNG in the VM (feeding through it the entropy from the host system)./dev/randomis not a HWRNG, by the way.

You should be able to use the virtio-rng kernel module (in the guest). See this article for more details. I'm not sure whether VirtualBox supports it yet - if not, you might want to give QEMU a try.
