Libvirt uses gnulib for making winsock look like POSIX sockets. This means that in the libvirt event handle callbacks the application will be given a file descriptor rather than a winsock HANDLE object. The g_io_channel_unix_new method will detect that it is an FD and delegate to the g_io_channel_win32_new_fd method. Unfortunately the glib Win32 event loop impl is not very good at dealing with FD objects, simulating poll() by doing a read() on the FD :-( The API docs for g_io_channel_win32_new_fd say "All reads from the file descriptor should be done by this internal GLib thread. Your code should call only g_io_channel_read()." This isn't going to fly for libvirt, since it has zero knowledge of glib at all, so is just doing normal read(). Fortunately we can work around this problem by turning the FD we get from libvirt back into a HANDLE using the _get_osfhandle() method. Signed-off-by: Daniel P. Berrange <berrange@redhat.com> |

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
