The -vnc argument is documented as accepting two syntaxes for the 'websocket' option, either a bare option name, or a port number. If using the bare option name, it is supposed to apply the display number as an offset to base port 5700. e.g. -vnc localhost:3,websocket should listen on port 5703, however, this was broken in 2.3.0 since commit 4db14629c38611061fc19ec6927405923de84f08 Author: Gerd Hoffmann <kraxel@redhat.com> Date: Tue Sep 16 12:33:03 2014 +0200 vnc: switch to QemuOpts, allow multiple servers instead qemu tries to listen on port "on" which gets looked up in /etc/services and fails.
