Virtualbox has three start modes:
- normal (with a window for the VM but window cannot be closed)
- headless start (no window for the VM, but you can see a screenshot in VBox UI)
- detachable start (a mix of the above two; window can be closed without turning off VM)
I was wondering, why do they have these three options when the third one satisfies the first and second? Is it possible there are also performance reasons?
In other words, why should I ever need to use the other options?
