Appendix A. Lab 1
Xen Guest Installation
Goal: To install RHEL 3, 4, or 5 and Windows XP Xen guests.
Prerequisites: A workstation installed with Red Hat Enterprise Linux 5.0 with Virtualization
component.
For this lab, you will configure and install RHEL 3, 4, or 5 and Win XP Xen guests using various
virtualization tools.
Lab Sequence 1: Checking for PAE support
You must determine whether your system has PAE support. Red Hat Virtualization supports
x86_64 or ia64 based CPU architectures to run para-virtualized guests. To run i386 guests the
system requires a CPU with PAE extensions. Many older laptops (particularly those based on
Pentium Mobile or Centrino) do not support PAE.
1. To determine if your CPU has PAE support, type:
grep pae /proc/cpuinfo
2. The following output shows a CPU that has PAE support. If the command returns nothing,
then the CPU does not have PAE support. All the lab exercises require a i386 CPU with PAE
extension or x86_64 or ia64 in order to proceed.

Lab Sequence 2: Installing RHEL5 Beta 2 Xen para-virtualized guest using virt-install.
For this lab, you must install a Red Hat Enterprise Linux 5 Beta 2 Xen guest using
virt-install.
1. To install your Red Hat Enterprise Linux 5 Beta 2 Xen guest, at the command prompt type:
virt-install.
2. When asked to install a fully virtualized guest, type: no.
