I haven't added it myself and it says that it's an inherited permission

You probably added the user role to the user from the users tab, rather
than just adding at vm level . You don't need to add the user first.

creating/editing VMs. I mentioned this more as a way to explain why UserB
was initially not able to connect to UserA's VM where in fact, it was
possible upon a clean boot.
