[Qemu-devel] patch to change window title in qemu vnc

Hi,

enclosed you find a patch, that changes the window title as seen by VNC 
clients connecting to qemu vnc-sessions from "QEMU" to "QEMU VNC:" 
followed by the displaynumber you specified with the command line 
parameter -vnc :0.

This comes in very handy in case you have different qemu instances 
running on a remote host, and you access them via vnc, as the client's 
window title gives you a hint to which virtual machine you are connected 
right now.

Regards, Andreas

This is already supported via the -name parameter.  Your patch is 
against an old copy of QEMU.
