HP Insight Control for Linux 6.0 User Guide

12 Installing and setting up virtual machines
This chapter addresses the following tasks, which you must complete in this order:
1. “Installing virtual hosts” (page 139)
2. “Registering the virtual host with HP Insight Control virtual machine management” (page 140)
3. “Creating and installing virtual guests” (page 141)
4. “Obtaining virtual guest and virtual host associations” (page 143)
5. “Establishing monitoring for virtual hosts and virtual guests” (page 144)
NOTES:
• By default, CPU virtualization enhancements are disabled in HP servers. For servers to be
used for virtualization, especially for fully virtualized guests, change the following BIOS
setting on the server accordingly; for example:
Advanced options→Processor Options...→Intel(r) Virtualization Technology.
Advanced options→Processor Options...→AMD Virtualization.
These enhancements are required for virtualization using Xen and are recommended for
VMware ESX and VMware ESXi virtualization operating systems.
The BIOS settings in your server might vary slightly.
• The following BIOS setting needs to be enabled for VMware ESX and VMware ESXi
virtualization operating systems:
Advanced options→Processor Options...→No-Execute Memory Protection
By default, this option is set to Disabled.
12.1 Installing virtual hosts
The next step is to install the operating system that enables a physical server to act as a virtual
host.
HP provides templates for the installation configuration files for virtual hosts; use a copy of the
configuration file, edited for your environment. These templates are located in the Insight Control
for Linux repository; they are identifiable by the text -virt-host; for example:
rh052–virt-host
Kickstart for RHEL 5 Update 2 with Virtualization – Host
sl102–virt-host
AutoYaST for SLES 10 Update 2 with Virtualization – Host
esx040
Installation configuration file for VMware ESX
Use these templates to create your own installation configuration files, suited your environment.
Remember to register your installation configuration files in the Insight Control for Linux
Repository.
The steps to install a virtual host are:
1. Discover the physical host.
The host must appear as a managed system recognized by HP SIM.
2. Set the Global Sign-In credentials for the virtual host with the
Options→Security→Credentials→Global Credentials... menu item.
3. Install the appropriate operating system with virtualized configuration on the physical
server of your choice. Chapter 7 (page 81) describes the steps for using Insight Control for
Linux to install a Linux operating system.
4. Run Options→Identify Systems... to verify the installation.
The next step is to register the virtual host with the virtual machine management.
