Dan Berrange and I have been talking about being able to move VNC server into a central process such that all of the VMs can have a single VNC port that can be connected to. This greatly simplifies the firewalling logic that an administrator has to deal with. That's a problem I've already had to deal with for our management tools. We use a private network for management and we bridge the VNC traffic into the customers network so they can see the VGA session. But since that traffic can be a large range of ports and we have to tunnel the traffic through a central server to get into the customer network, it's very difficult to setup without opening up a mess of ports. I think we're currently opening a few thousand just for VNC.
Seems to me the best way to handle this is to run an accept() in a server and hand the resulting fd to the vnc server in qemu using ... wait for it ... SCM_RIGHTS.
I'm just happy every time someone lobs a question into the air that can be answered using SCM_RIGHTS.
