Hi Narcis, Thank you for the extra details: the documentation is quite terse if not insufficient. I mean: https://qemu.weilnetz.de/doc/qemu-doc.html linked as the official user manual from http://wiki.qemu.org/Manual.
According to your experience, which approach is the "lightest" among "-display vnc" and "-ncurses"? Finally, may I ask you where did you pull these details from?
