I am working on a project that runs many concurrent qemu sessions with vnc.
Adding the following option:
-vnc-socket sd [force VNC server on an already opened Socket Descriptor]

Just redirect each port to a unique unix domain socket and then you can forward traffic to TCP sockets to your heart's content.

Hi Anthony,

Thanks for your comment.

The problem with the solution you suggest is that all VNC traffic will be first sent to the unix domain socket, and then copied to the TCP socket. This double work may be acceptable if we're talking about one instance of qemu, but as I said, I run many concurrent sessions which create too much load. In the solution I suggest, this extra copying is not needed.
