No, this is not going to happen.
But qemu-dm in this case doesn't use many resources; if you are using
vnc and you don't have any client connected it is basically doing nothing,
otherwise just exporting the framebuffer or rendering to X11.
It is the same binary but this is the only thing in common between the
two qemu cases.
