17.3. Running the Installation Program

After following the steps outlined in Chapter 16, Steps to Get You Started for booting an LPAR or VM system, ssh to the configured Linux install system on the IBM System z.
Although the text mode installation program is run by default for most installations, you can optionally run the graphical installation program available for both VM and LPAR installations via the NFS installation method.

Note

If you have a slow network connection or prefer a text-based installation, do not set the DISPLAY= variable in the parm file. The text-based installation is similar to the graphical installation; however, the graphical installation offers more package selection details and other options not available in text-based installs. It is strongly recommended to use the graphical installation whenever possible.
To run the graphical installation, use a workstation that has an X Window System server or VNC client installed. Use an SSH client that allows X11 forwarding or a Telnet client. SSH is strongly recommended for its security features as well as its ability to forward X and VNC sessions. Enable X11 forwarding in your SSH client prior to connecting to the Linux image (the Linux guest running on z/VM).

17.3.1. Installation using X11 Forwarding
For example, to connect to the Linux image and display the graphical installation program using OpenSSH with X11 forwarding on a Linux workstation, type the following at the workstation shell prompt: 
ssh -X 
linuxvm.example.com
The -X option enables X11 forwarding.
The graphical installation program cannot be started if your DNS or hostnames are not set correctly, or the Linux image is not allowed to open applications on your display. You can prevent this by setting a correct DISPLAY= variable. Add the parameter DISPLAY= workstationname :0.0 in the parameter file, replacing workstationname with the hostname of the client workstation connecting to the Linux Image. Allow the Linux image to connect to the workstation using the command xhost +linuxvm on the local workstation.
If the graphical installation via NFS does not automatically begin for you, verify the DISPLAY= variable settings in the parm file. If performing a VM installation, rerun the installation to load the new parm file on the reader. Additionally, make sure when performing an X11 forwarded display that the X server is started on the workstation machine. Finally, make sure either the NFS, FTP or HTTP protocols are selected, as all 3 methods support graphical installations.
