where the value of the -geometry parameter can be any valid screen width and height.

4. Save and close the file.

4.8.2. Setting up SLES-based VMs for VNC

Note

Before setting up your SUSE Linux Enterprise Server VMs for VNC, be sure that you have installed

the Linux guest agent. See Section 4.5, “Installing the Linux guest agent” for details.

SLES has support for enabling “Remote Administration” as a configuration option in YaST. You can select

to enable Remote Administration at install time, available on the Network Services screen of the SLES

installer. This will allow you to connect an external VNC viewer to your guest to view the graphical console;

the methodology for using the SLES remote administration feature is slightly different than that provided by

XenCenter, but it is possible to modify the configuration files in your SUSE Linux VM such that it is integrated

with the graphical console feature.

4.8.2.1. Checking for a VNCserver

Before making configuration changes, you should verify that you have a VNC server installed. SUSE ships

the tightvnc server by default; this is a suitable VNC server, but you can also use the standard RealVNC

distribution if you prefer.

You can check that you have the tightvnc software installed by running the command:

rpm -q tightvnc

4.8.2.2. Enabling Remote Administration

If Remote Administration was not enabled during installation of the SLES software, you can enable it as

follows:

1. Open a text console on the VM and run the YaST utility:

# yast

2. Use the arrow keys to select Network Services in the left menu, then Tab to the right menu and use

the arrow keys to select Remote Administration. Press Enter.

3. In the Remote Administration screen, Tab to the Remote Administration Settings section. Use the arrow

keys to select Allow Remote Administration and press Enter to place an X in the checkbox.

4. Tab to the Firewall Settings section. Use the arrow keys to select Open Port in Firewall and press Enter

to place an X in the checkbox.

5. Tab to the Finish button and press Enter.

6. A messsage box appears telling you that you will need to restart the display manager for your settings

to take effect. Press Enter to acknowledge the message.
