That could be done. it would require replacing the generic /dev/random with
a UML one, and I don't know whether the kernel build makes that easy.
Another alternative is to add an mconsole interface to dump randomness into
a UML when it starts running out.
The current UML practice of feeding /dev/random from the drivers is a bit
suspect. The randomness obtained there is related to the host randomness,
but the host random pool isn't depleted accordingly.
I think the right solution is to feed UML /dev/random from the host /dev/random
somehow.
