Reorganize the high-level design docs to align with a work-in-progress HLD document. Migrate previous web content (and images) into the new organization. From here we'll continue inclusion of new design chapters as they're reviewed and edited. Signed-off-by: David B. Kinder <david.b.kinder@intel.com>

The virtio-rnd entropy device supplies high-quality randomness for guest
|
|
use. The virtio device ID of the virtio-rnd device is 4, and it supports
|
|
one virtqueue, the size of which is 64, configurable in the source code.
|
|
It has no feature bits defined.
|
|
|
|
When the FE driver requires some random bytes, the BE device will place
|
|
bytes of random data onto the virtqueue.
|
|
|
|
To launch the virtio-rnd device, use the following virtio command::
|
|
|
|
-s <slot>,virtio-rnd
|
|
|
|
To verify the correctness in user OS, use the following
|
|
command::
|
|
|
|
od /dev/random
