Assistance is welcome in verifying that the settings on this wiki page match those we are using in Whonix source code. This ensures that no settings have been forgotten. If interested, click on Expand on the right.

In Whonix source code, examine build-steps.d/2500_create-vbox-vm for the functions general_setup and workstation_specific. Apply any missing settings from build-steps.d/2500_create-vbox-vm. It is also sensible to drop the "sudo -u $USERNAME" setting.

The following settings are not required. They are either recommended earlier on, or done by the gui creation process:

  • --name
  • storagectl
  • storageattach
  • --memory
  • --pae
  • --intnet1
  • --cableconnected
  • --macaddress1
  • --audiocontroller
  • --audio
  • --rtcuseutc

  1. The Whonix-Custom-Workstation template already comes with these settings by default.
  2. For further reading on why these settings are beneficial, see build-steps.d/2500_create-vbox-vm in the Whonix source code folder.
  3. This is a precautionary measure.
