[Following the Guide “Discourse as Your First Rails App”](http://blog.discourse.org/2013/04/discourse-as-your-first-rails-app/) (hopefully), I’m having trouble running:

```
vagrant up

```

When doing so, I get some messages:

```

I’m really clueless:

- Is there anything fundamentally that I forgot?
- Do I have to set up my own virtual machine first?
- Is it a problem that I have VMware Workstation also installed?

[It seems to be an issue with Virtual Box](http://stackoverflow.com/a/38427158/107625). You could either downgrade Virtual Box or [manually do some steps](https://github.com/mitchellh/vagrant/issues/7465#issuecomment-233157377) to fix it.

I’ve followed the steps to manually fix it and now `vagrant up` seems to work.
