3.2 Preparation Edit source

This section describes the preparatory steps that must be taken before the actual installation of SUSE Linux Enterprise Server. The installation procedure depends on the system used. The following methods are supported:

If SUSE® Linux Enterprise Server needs to be installed on several systems or partitions, it is recommended you create a network installation source. The same source can also be used for the concurrent installation on several partitions or several systems. The configuration of a network installation source is described in Section 8.1, “Setting Up an Installation Server Using YaST”.

3.2.1 Installation on Servers with IBM PowerKVM using Kimchi Edit source

This section covers the preparatory steps for installing on IBM PowerLinux systems with PowerKVM. It explains the installation from an ISO image with the Kimchi Web interface. Kimchi is a tool for administrating IBM PowerKVM.

This section assumes you have PowerKVM running on your IBM PowerLinux server. If PowerKVM is not preinstalled see Configuring IBM PowerKVM on Power Systems at http://www.ibm.com/support/knowledgecenter/linuxonibm/liabp/liabpkickoff.htm for installing and setting up PowerKVM.

3.2.1.1 Creating a SUSE Linux Enterprise Server Template with Kimchi Edit source

Templates are the installation source for PowerKVM guests. You can create a template, edit an existing template, or clone a template. To clone a template from an existing guest, that guest must be deactivated.

Procedure 3.1: Creating a Template with Kimchi
  1. In the Web browser, enter the URL of the PowerLinux server where PowerKVM is running, for example https://POWERLINUX_IP:8001 (replace POWERLINUX_IP with the IP address of your system).

  2. Click the Templates tab to activate the Templates page.

  3. Click the green plus sign (+) to create the SUSE Linux Enterprise Server template.

  4. On the Add Template dialog, select from the following options:

Now you can continue with the default installation via VNC as described in Section 6.3, “Steps of the Installation”.

3.2.2 Installation on Servers with IBM PowerKVM using virt-install Edit source

Alternatively to installing with Kimchi, use the virt-install command line tool to install on servers with IBM PowerKVM. This is especially useful you need to install multiple virtual machines on IBM PowerLinux Server systems. virt-install allows many installation scenarios; in the following a remote installation scenario via VNC and PXE boot is outlined. For more information about virt-install, see Section 9.2, “Installing from the Command Line with virt-install.

Prepare a repository with the installation sources and PXE boot enabled target system as described in Section 10.1.3, “Remote Installation via VNC—PXE Boot and Wake on LAN”.

On the command line, enter something similar as follows (adjust the options according to your needs and matching your hardware):

virt-install --name server_sle12 --memory 4096 --vcpus=2 --pxe \
--graphics vnc --os-variant sles11 \
--disk pool=default,size=3000,format=qcow2,allocation=1G,bus=virtio \
-w mac=MAC_ADDRESS,model=spapr-vlan

It will use VNC graphics, and it will automatically launch the graphical client. Complete the installation as described in Section 6.3, “Steps of the Installation”.

3.2.3 Installation in a Partition Using IVM Edit source
