In the past it was possible to set the port for vnc with: -vnc :1 That would mean the port would be 5901, Starting from 5900 plus the given number. However, it was also possible to set the port directly with a custom given port. Usually i set the port to something like 5801. With qemu-1.1.1 and qemu-1.2.2-r3 (maybe prior versions too, i usually use spice) that's not possible anymore. For example: -vnc 192.168.1.1:5804 Here the 'real' port would be 11704 (that's 5900 + 5804). I'm sure that worked correctly in the past, as i'm used it quite often. I already made an upstream bugreport without any answer so far. However, i just though to report it here too. Qemu version also changed to the latest stable.

I can't remember a version where it behaved like that ever. I did however read this and immediately think of XKCD. http://xkcd.com/1172/
I would take this to the qemu users ML, https://lists.nongnu.org/mailman/listinfo/qemu-discuss
(In reply to Doug Goldstein from comment #2) > I would take this to the qemu users ML, > https://lists.nongnu.org/mailman/listinfo/qemu-discuss Thanks for the reminder on that issue, i just send an mail on that list. In the meantime i have an workaround for that issue which i'm using in my start/stop script for qemu guests. It actually calculates the port via: "${given_port} + 59635 - 65535" Starting a guest with port 5804 would actually start the guest with -vnc ${ip}:-96 It's a bit strange, but it works :) BTW, nice analogy with xkcd. love this one :D
Going to mark this as upstream since we'll really want the change for this to land upstream rather than carrying a downstream patch.
