None, indeed.

My host is a headless server and I'd like to save all resources I can
from it to give them to the guests.
So I need remote access to the guests that I would like to do with
SSH, RDP or VNC
(the latter two with SSH tunnels).

VNC seems to me a solution, but I couldn't find enough details about
the curses solution which
would be my preferred solution because of its low requirements.
Where is the ncurses output pushed to? A local PTY? A Unix socket?

Why cannot I use -nographic with -daemonize (and VNC)?
