When using a custom fullscreen display configuration, it's possible to specify that e.g. a single screen should be fullscreen on client monitor #4. Since we send down absolute positions and disable alignment when all windows are in fullscreen, we can send configurations with a very large offset to the top-left corner. This could result in the guest trying to create a screen that was much larger than necessary. For example when sending a configuration of 1280x1024+4240+0, the guest would need to allocate a screen of size 5520x1024, which might fail if video memory was too low. To avoid this issue, we shift all displays so that the minimum X coordinate for all screens is at x=0, and the minimum y coordinate is at y=0. |

Virt Viewer =========== Virt Viewer provides a graphical viewer for the guest OS display. At this time is supports guest OS using the VNC or SPICE protocols. Further protocols may be supported in the future as user demand dicatates. The viewer can connect directly to both local and remotely hosted guest OS, optionally using SSL/TLS encryption. Virt Viewer can be built with either GTK2 or GTK3, with the default option currently being GTK2. The choice can be made with: ./configure --with-gtk=3.0 (or =2.0) Virt Viewer uses the GTK-VNC (>= 0.4.3) widget to provide a display of the VNC protocol, which is available from http://gtk-vnc.sourceforge.net/ Virt Viewer uses the SPICE-GTK (>= 0.22) widget to provide a display of the SPICE protocol, which is available from: http://spice-space.org/page/Spice-Gtk Use of either SPICE-GTK or GTK-VNC can be disabled at time of configure, with --without-gtk-vnc or --without-spice-gtk respectively. Virt Viewer uses libvirt to lookup information about the guest OS display. This is available from http://libvirt.org/ Further information about the Virt Viewer application can be found on the Virt Manager website: http://virt-manager.org/ Feedback should be directed to the mailing list at http://virt-manager.org/mailinglist.html -- End
