This section describes how to configure VNC on each of the supported Linux operating system distributions to allow proper interactions with XenCenter.

In the recommended configuration, a standard display manager controls the console so that a login dialog box is provided. Install your Debian guest with the desktop system packages, or install GDM the display manager using apt following standard procedures. Install the Xvnc server using apt-get or similar :. Uninstall the Gnome Display Manager gdm3 package and install the gdm package as follows:. Set up a VNC password not having one is a serious security risk by using the vncpasswd command.

Pass in a file name to write the password information to. For example:. Modify your gdm. You can check that the VNC server is running using a command like ps ax grep vnc. The GDM configuration is held in a file whose location varies depending on the version of Red Hat Linux you are using.

Before modifying it, first determine the location of this configuration file. This file is modified in several subsequent procedures in this section. This file is a split configuration file that contains only user-specified values that override the default configuration. This type of file is used by default in newer versions of GDM.

It is included in these versions of Red Hat Linux. The package names vnc-server and gdm appear, with their version numbers specified. The package names that are displayed show the packages that are already installed. If you see a message that says that a package is not installed, you might have not selected the graphical desktop options during installation. Install these packages before you can continue. Open the GDM configuration file with your preferred text editor and add the following lines to the file:.

With configuration files on Red Hat Linux, add these lines into the empty [servers] section. Modify the configuration so that the Xvnc server is used instead of the standard X server:. If you are using Red Hat Linux, add the above line just below the [servers] section and before the [server-VNC] section. Red Hat Linux uses runlevel 5 for graphical startup.

If your installation starts up in runlevel 3, change this configuration for the display manager to be started and get access to a graphical console. For more information, see Check Run levels. The firewall configuration by default does not allow VNC traffic to go through. Consult your firewall documentation to ensure that these ports are open. If you want to use IP connection tracking or limit the initiation of connections to be from one side only, further configure your firewall.

For Red Hat Linux, use system-config-securitylevel-tui. Select Customize and add to the other ports list. Alternatively, you can disable the firewall until the next reboot by running the command service iptables stop , or permanently by running chkconfig iptables off. This configuration can expose extra services to the outside world and reduce the overall security of your VM.

For example, the VM display is too large to fit comfortably in the Graphical Console pane. Control this behavior by setting the VNC server geometry parameter as follows:. Open the GDM configuration file with your preferred text editor.

Find the [server-VNC] section you added above. The value of the geometry parameter can be any valid screen width and height. During the operating system installation, select Desktop mode. Open the GDM configuration file with your preferred text editor and add the following lines to the appropriate sections:. Enter the following command to start the xinetd service:. Enter the following command to restart iptables :. Enter the following command to restart gdm :.

If your installation starts up in runlevel 3, change this configuration for the display manager be started and to get access to a graphical console. For more information, see Check run levels. This feature allows you to connect an external VNC viewer to your guest to allow you to view the graphical console.

The method for using the SLES remote administration feature is slightly different than the method provided by XenCenter. However, it is possible to modify the configuration files in your SUSE Linux VM such that it is integrated with the graphical console feature. Before making configuration changes, verify that you have a VNC server installed.
