Debugging

As much as we try to keep Vagrant stable and bug free, it is inevitable that issues will arise and Vagrant will behave in unexpected ways. In these cases, Vagrant has amazing support channels available to assist you.

When using these support channels, it is generally helpful to include debugging logs along with any error reports. These logs can often help you troubleshoot any problems you may be having.

To enable detailed logging, set the VAGRANT_LOG environmental variable to the desired log level name, which is one of debug (loud), info (normal), warn (quiet), and error (very quiet). When asking for support, please set this to debug. When troubleshooting your own issues, you should start with info, which is much quieter, but contains important information about the behavior of Vagrant.

On Linux and Mac systems, this can be done by prepending the vagrant command with an environmental variable declaration:

  1. $ VAGRANT_LOG=info vagrant up
  2. ...

On Windows, multiple steps are required:

  1. $ set VAGRANT_LOG=info
  2. $ vagrant up
  3. ...

You can also get the debug level output using the --debug command line option. For example:

  1. $ vagrant up --debug
  2. ...

If you plan on submitting a bug report, please submit debug-level logs along with the report using gist or some other paste service.
