HP Integrity Virtual Server Manager 6.3 User Guide

6 Working with VMs or vPars
This chapter describes tasks you can perform to create and manage VMs or vPars and their
resources.
NOTE: Integrity Virtual Server Manager version 6.1 supports only one type of guest. If the first
guest created on Virtual Server Manager is a vPar, then only vPar guests can be created on that
VSP. If the first guest created is a VM, then only VMs can be created on that VSP. But, with Integrity
Virtual Server Manager version 6.2, VMs and vPars coexist on the same host.
Working with VMs
Planning VMs
To achieve your goals using VMs, plan the configuration of each VM by assessing its requirements
for resources on the HP Integrity system on which it will run. For information about how to assess
your system's resources as well as the VMs you will run on the system, and how to map your VM
requirements to the system's resources, see the HP-UX vPars and Integrity VM Administrator Guide
manual, located on the HP Technical Documentation website (click on the HP Matrix Operating
Environment for HP-UX tab):

For information about AVIO performance tuning, see the latest Integrity VM white papers available
from this website.
Creating VMs
To create a VM, Integrity Virtual Server Manager uses the Create Virtual Machine wizard to guide
you through the process. Each step presents a dialog that allows you to specify the required
information. At any time you can get help, return to previous steps, or exit the wizard. By creating
a new VM, you assign attributes and resources to it. This creates an association among the virtual
devices known to the VM and the physical devices managed by the VSP.
Where possible, reasonable default values are provided for each dialog. However, the default
values are not necessarily optimal. You must determine what values are optimal based on the
unique requirements of your machine (such as the applications you plan to run and the performance
you expect).
To access the Create Virtual Machine wizard, select Create→Virtual Machine... from the Integrity
Virtual Server Manager menu bar. The Create Virtual Machine wizard leads you through several
screens in the following order. For more information about any screen, see the corresponding
Integrity Virtual Server Manager help topic.
1. Specify VM Identity
Specify the VM name, an optional description, the intended guest operating system, and the
VM hardware startup value (autoboot).
2. Specify Processor Entitlements
The processor entitlement sets the guaranteed amount of processing power for each virtual
CPU in a VM. The processor entitlement is the default entitlement (10%), a percentage of
physical processor power, or a specific, fixed processor speed. If supported by the version
of Integrity VM running on the VSP, you can specify an entitlement cap and the minimum and
maximum number of vCPUs to be allotted to the VM. An entitlement cap is the maximum
amount of computing power allotted to a VM for each vCPU.
To enable online migration between Itanium 9300 and Itanium 9500 based systems, select
Enable Online Migration between Itanium 9300 and Itanium 9500 check box. By default, this
checkbox is not selected.
