The only thing that actually works is to "pierce the virtualization" and give the VM access to true random number generation on the host (assuming *it* has a decent source of random numbers).  This is pretty universally available in VMM's these days, and modern guest OS's make use of the facilities provided.

No, getting this right isn't trivial.  And it introduces new potential attacks.
