ack and assigned, apparently the right API to use for that is g_socket_set_timeout() (reset it once connected) Sent patches to both Spice: http://lists.freedesktop.org/archives/spice-devel/2013-May/013408.html and gtk-vnc: https://bugzilla.gnome.org/show_bug.cgi?id=700240 fixed in spice-gtk-0.20-1.el6 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: When remote-viewer connecting to a unreachable graphic server, the waiting time longer than 60 seconds. No error message pop up in the period of time. The waiting time should be shorter when connecting to a unreachable server. This issue scenario happened after remote-viewer has connected a guest successfully. Here is the detail: #remote-viewer vnc://1.2.3.4:59000 --debug ** (remote-viewer:4225): DEBUG: Insert window 0 0x132c010 ** (remote-viewer:4225): DEBUG: fullscreen display 0: 0 ** (remote-viewer:4225): DEBUG: fullscreen display 0: 0 ** (remote-viewer:4225): DEBUG: Opening display to vnc://1.2.3.4:59000 ** (remote-viewer:4225): DEBUG: Guest vnc://1.2.3.4:59000 has a vnc display ** (remote-viewer:4225): DEBUG: After open connection callback fd=-1 ** (remote-viewer:4225): DEBUG: Opening connection to display at vnc://1.2.3.4:59000 ** (remote-viewer:4225): DEBUG: notebook show status 0x132d020 ** (remote-viewer:4225): DEBUG: Disconnected ** (remote-viewer:4225): DEBUG: close vnc=0x136fb10 ** (remote-viewer:4225): DEBUG: notebook show status 0x132d020 ** (remote-viewer:4225): DEBUG: Guest vnc://1.2.3.4:59000 display has disconnected, shutting down ** (remote-viewer:4225): DEBUG: Disposing window 0x132c010 At the same time, use tcpdump catch the tcp packages: remote-viewer try to establish a tcp connection for some times.

Expected results: The timeout value should not set 60 seconds, which make user wait for a bit long time. Additional info: This issue scenario happened after remote-viewer has connected a guest successfully.
