I'm confused by the inclusion of rng-tools into the Vagrant VM. Is your intent to expose the hardware RNG on the host machine to the VM and use rng-tools daemon to seed the entropy pool using that hardware RNG from the host?
If your hypervisor doesn't support passthorugh of a hardware RNG or your server doesn't have one, you can use http://www.issihosts.com/haveged/ to generate entropy to be used in VM's.
