For all of you posting the sudo command claiming it works, and to others claiming it does not:
I have 3 parallels machines on my mac, Linux, Windows 10 enterprise, Windows server 2019 + bootcamp .
I also have bootcamp, well obviously for playing only with Windows 10 Pro. Other 3 are for work. When lunching the command it FORCED bootcamp windows into PD. I did not even have it added. Yes it works, it has network. BUT its bootcamp. I do not want that VM, I need other 3 that are not.
So My guess is this ONLY works on bootcamp VMS for some reason and for others is failing. Not all people use bootcamp.
BTW; Big sur, PD 16.1.1 business edition.
