@Paresh Adhia, You are correct, the VM is there to run docker. This allows the same sandbox container to be run on many different virtualization platforms, which reduces the variability of the experience for different users.

In fact, there is a github repository of tools for running multi-node clusters in docker. You can find a link to that here: https://community.hortonworks.com/repos/75668/a-multi-node-docker-cluster-platform-to-quickly-sp.html ... View more
