IIRC UML RNG device reads directly from host.

Yes, but that's a /dev/hwrng device, so you still need some userspace to feed entropy from that into /dev/random.

If you are using UMLs own /dev/random you are effectively using the host one.

So unless I am mistaken, you need extra randomness only if you do not have UMLs /dev/random compiled in.

No, neither of those is true.
