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.
!> Scan for sensitive information! Vagrant debug logs include information about your system including environment variables and user information. If you store sensitive information in the environment or in your user account, please scan or scrub the debug log of this information before uploading the contents to the public Internet.
~> Submit debug logs using GitHub Gist. If you plan on submitting a bug report or issue that includes debug-level logs, please use a service like Gist. Do not paste the raw debug logs into an issue as it makes it very difficult to scroll and parse the information.
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:
$ VAGRANT_LOG=info vagrant up
On Windows, multiple steps are required:
$ set VAGRANT_LOG=info
$ vagrant up
You can also get the debug level output using the --debug command line
option. For example:
$ vagrant up --debug
If you are saving the output to a file, you may need to redirect stderr and
stdout using &>:
$ vagrant up --debug &> vagrant.log
