> Currently the
> [vagrant-puppet|https://github.com/apache/bigtop/tree/master/bigtop-deploy/vm/vagrant-puppet]
> deployment use Virtualbox as VM provider. The visualized hardware in
> Virtualbox does not have good performance on entropy generation since such
> randomness often collected from hardware sources.
> The poor entropy performance directly impact the use in cryptography or use
> that required random data, which in our case is kerberos. In order to test
> our code snipes for real world usage instead of suffering on virtual
> machines, we can improve the entropy performance on VMs using rng-tools when
> provisioning those test VMs.
