Permanently add this parameter to your boot loader conguration by adding

the parameter dom0_mem=VALUE to your Xen kernel boot conguration. Either

use YaST > System > Boot Loader or edit /boot/grub/menu.lst. See Sec-

tion 2.3, “Managing Domain 0 Memory” (page 11) for more information.

Updates are available through your update channel. To be sure to have the latest updates

installed, run YaST Online Update after the installation has nished.

2.1 Best Practices and Suggestions

When installing and conguring the SUSE Linux Enterprise operating system on the

host, be aware of the following best practices and suggestions:

•

If the host should always run as Xen host, run YaST System > Boot Loader and acti-

vate the Xen boot entry as default boot section.

•

In YaST, click System > Boot Loader.

•

Change the default boot to the Xen label, then click Set as Default.

•

Click Finish.

• Disable powersave functionality on the host and all guest operating systems. On the

host computer and other Linux computers, you can use the chkconfig

powersaved off command.

• Close Virtual Machine Manager if you are not actively using it and restart it when

needed. Closing Virtual Machine Manager does not affect the state of virtual machines.

• For best performance, only the applications and processes required for virtualization

should be installed on the virtual machine host.

• When using both, iSCSI and OCFS2 to host Xen images, the latency required for

OCFS2 default timeouts in SUSE Linux Enterprise Server may not be met. To recon-

gure this timeout, run /etc/init.d/o2cb configure or edit

O2CB_HEARTBEAT_THRESHOLD in the system conguration.
