This option enables UML's "hardware" random number generator. It

attaches itself to the host's /dev/random, supplying as much entropy
|
|
as the host has, rather than the small amount the UML gets from its

own drivers. It registers itself as a standard hardware random number

generator, major 10, minor 183, and the canonical device name is

/dev/hwrng.

The way to make use of this is to install the rng-tools package
|
|
(check your distro, or download from
|
|
http://sourceforge.net/projects/gkernel/). rngd periodically reads
|
|
/dev/hwrng and injects the entropy into /dev/random.
