Using the config.vagrant namespace we will look at configuring Vagrant specifically. There are not many options available within this namespace compared to the others we have already looked at. The commands for the config.vagrant namespace are as follows:

• config.vagrant.host is used to set the host machine that is running Vagrant. The default value is :detect, which allows Vagrant to intelligently auto-detect the host. Certain features Vagrant offers are host-specific and this value is only recommended to be changed if auto-detection fails.
• config.vagrant.sensitive is used to supply a list or array of items that will not be displayed in Vagrant's output or logged output. These values are often passwords or keys.
