[Qemu-devel] [PATCH 1/8] ui: fix regression handling bare 'websocket' option to -vnc |
Date: |

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

vnc: switch to QemuOpts, allow multiple servers
instead qemu tries to listen on port "on" which gets looked up in
/etc/services and fails.
Fixes bug: #1455912
