This looks great, but do we have a vagrant file?

[KrishMunot]

Yes, we do have a vagrant file
I hope this can get merged. 😃

Oh, ok didn't realize that this was on top of the other PR. It might be nice to rebase your commit on top of that other PR and then submit them together as the PR, since we would want to merge them at the same time (not one without the other).

Your doc mentions the tools/vagrant directory, which doesn't look like it exists. Does that get created somehow?

[KrishMunot]

Yes, that makes sense. :)

Yea, the directory gets created automatically that way.

Hi @KrishMunot , I saw your PR is using vagrant and ansible, but #1104 dosen't using ansible, and the Vagrantfile is in the project's root folder (I think it's common usage for most projuect).
