[Qemu-devel] [PATCH] Add an info vnc monitor command |

Thunderbird 1.5.0.9 (X11/20070103) |
The following patch adds an info vnc monitor command. When writing a
front-end, it's useful to be able to determine 1) if a client is current
connected to the VNC server and 2) what the VNC server is actually
listening on.
Regards,
Anthony Liguori
