Hi Ahmet, 
sorry I couldn´t reply earlier.
Thanks for your latest comments.
Right. I was under the impression you were talking about cli-commands.
I see now you were referring to the GUI. 
Well, I have that installed as well. My version however seems to be lower than yours:
It´s version 2.2.1.
But it works very well and apart from trying EasyOS to get to run/install I never ran into any problems.
I guess I still have to download the latest EasyOS version 4.3.4 and see whether this is better suited for running in a vm.
Thanks also for the link and many greetings.
