The first thing i want to ask why on gateway by default “Shared Clipboard” is enabled (Host To Guest) ? On workstation it is disabled, i think if its useful is more usefull on workstation.
In the link above you talking about removing floppy,dvd from virtualbox instance. Do you mean removing these from boot order and/or storage menu ?
If removing from storage menu, do i only need remove DVD device only or controler also ?
I notice that i have VNC extension in my virtualbox, can i remove that for hardering ?
If talking about virtualbox devices boot order, i see no need to have floppy.dvd here. Can you confirm that it is ok to remove them from boot sequence?
