Subject: Virt RNG?

Has anyone yet written a "hw" RNG module for virt, that reads the host's 
random number pool?

All this talk[1] about IRQF_SAMPLE_RANDOM in network drivers reminds me 
that virt guest instances should be grabbing random numbers from the 
host, especially if the host has a hardware RNG.
