If we go down that path, we have to come up with a way of feeding that
information to guest userspace. Patches welcome. If we meanwhile assume
entropy == #bits, it fits the current /dev/hwrng model, and we can add an
entropy count later if we want to change that.
I'll change my lguest implementation to suck from /dev/random, since noone
else seems to consider its depletion to be a real issue. It's no worse than
what any other process can do.
Thanks,
Rusty.
