--OgqxwSJOaUobr8KG Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, I have virtualbox-ose-4.1.14 and libvncserver-0.9.9 installed on FreeBSD 9 and while I could start one VM using VBoxHeadless fine, the 2nd one would start but if I tried to attach to the VNC server it would crash with a bus error. The only thing I noticed in the startup messages was 12/05/2012 19:01:24 Listening for VNC connections on TCP port 5901 12/05/2012 19:01:24 rfbListenOnTCP6Port: error in bind IPv6 socket: Address already in use I tracked this down to libvncserver having IPv6 support but virtualbox not setting the IPv6 port, just the IPv4 port. I recompiled with debugging symbols and the attached patch and the crashes have stopped. I'm inclined to suspect that the patch stops the crash. I'm half pondering altering the patch a little so that if a port isn't specified it uses the autoprobe feature of libvncserver to find a free port rather than blindly assuming 5900 all the time.
