By adding a Random Number Generator device to Instances we can prevent
entropy starvation inside guest.
The default source is /dev/random on the host, but this can be configured
to another source when present, for example a hardware RNG.
When enabled it will add the following to the Instance's XML definition:
<rng model='virtio'>
<rate period='1000' bytes='2048' />
<backend model='random'>/dev/random</backend>
</rng>
If the Instance has the proper support, which most modern distributions have,
it will have a /dev/hwrng device which it can use for gathering entropy.
