HP Insight Control for Linux 6.2 User Guide

11 Installing and setting up virtual machines
This chapter addresses the following tasks, which you must complete in this order:
1. “Installing virtual hosts” (page 125)
2. “Registering the virtual host with HP Insight Control virtual machine management” (page 126)
3. “Creating and installing virtual guests” (page 127)
4. “Obtaining virtual guest and virtual host associations” (page 133)
5. “Establishing monitoring for virtual hosts and virtual guests” (page 134)
6. “Virtual guest operations” (page 134)
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.
11.1 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; the text -virt-host identifies them; for example:
rh055–virt-host-xen
Xen Kickstart for RHEL Version 5 Update 5 with Virtualization
Host
rh055–virt-host-kvm
KVM Kickstart for RHEL Version 5 Update 5 with Virtualization
Host
sll103–virt-host-xen
Xen AutoYaST for SLES Version 10 Service Pack 3 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.
For information on which virtualization operating systems Insight Control for Linux supports,
see HP Insight Control for Linux Support Matrix.
The steps to install a virtual host are:
1. Discover the physical host.
The host must appear as a managed system that HP SIM recognizes.
