Chapter 25. Tips and tricks

This chapter contains a number of scripts, tips and hints for using and enhancing Red Hat Virtualization.

25.1. Automatically starting domains during the host system boot

This section explains how to make guest systems boot automatically during the host system's boot phase. You need to configure soft links in /etc/xen/auto to point to the guest configuration file of the guests you want to automatically boot. It is recommended to keep the number of guests small because the boot order of guests is serialized. More guests automatically started at boot cause the boot sequence to take a significantly longer time.
The example below shows how you can configure the softlink for a guest image named example to automatic boot during the system boot.
# cd /etc/xen/auto
# ls
# ln -s /var/lib/xen/images/example .
# ls -l
lrwxrwxrwx 1 root root 14 Dec 14 10:02 example -> ../example
