HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

2 Installing and configuring VSP for HP-UX vPars and
Integrity VM V6.1
Installation of the VSP is the same whether you want to run a vPars only environment or a VM only
environment. The software bundles that need to be installed on the VSP are the same in either case.
This chapter describes the following:
• VSP installation requirements
• Configuring the VSP
• VSP cores
• VSP memory
• Hyperthreading setting on VSP
• VSP I/O configuration
• VSP kernel tunables
2.1 VSP installation requirements
The following software bundles must be installed on the VSP:
• HP-UX 11i v3 March 2012 (AR1203) (Base OE, VSE-OE, or DC-OE)
• BB068AA, VirtualBase (included with VSE-OE and DC-OE or as a separate install from the
application media)
• HP-UX GUID Manager
NOTE: The vPars and Integrity VM V6.1 bundle BB068AA does not include the HP Integrity
Virtual Server Manager software or the HP-UX GUID Manager software. You must install the HP-UX
GUID Manager, but the HP Integrity Virtual Server Manager is optional. Both these products are
separately installed ISU (Independent Software Unit) bundles. HP Integrity Virtual Server Manager
and the HP-UX GUID Manager can be downloaded from the HP Software Depot at http://
www.software.hp.com.
2.2 Configuing the VSP
After installation of the vPars and Integrity VM V6.1 product, the VSP is ready for use, you can
now create and manage vPars or VMs. As mentioned earlier, the V6.1 product supports either a
VM-only environment or a vPars-only environment. If you are planning to have a vPar environment,
create only vPars. If you are planning to have a VM environment, create only VMs.
Before creating vPars or VMs, you should be aware of the VSP settings. Note that the core and
memory setting in the VSP is configured appropriately when the product is started. There is no
change needed unless otherwise documented.
2.3 VSP cores
There are two CPU pools in the VSP: one for the dedicated VSP cores, and the other for use by
vPars/VMs. Use the hpvmhwmgmt -p cpu -l command to display the allocation of CPU cores.
2.3.1 vPar environment
As in vPars V6.0, you need at least one core reserved/dedicated to the VSP for starting vPars. In
vPars6.0, the cores reserved/allocated for VSP is one by default, even when there are no vPars
configured. In V6.1. VSP core is reserved/allocated automatically when the first vPar is created.
Also note that in vPars V6.0, all the non-VSP cores (cores available for allocation to vPars) were
