The binary voreentool (built by default alongside voreenve) can be used to run computations specified by workspaces or python scripts without a display.

Starting from Qt5 (and thus Voreen 5.0) you have to specify -platform minimal as a command line parameter which is then passed to Qt and makes it not require a display, e.g.:

./voreentool -platform minimal -w /path/to/my/workspace.vws --script /path/to/my/script.py
