HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

SGeRAC Serviceguard extension for real application clusters.
SGeSAP Serviceguard extension for SAP.
shared device A virtual device that can be used by more than one virtual machine.
SLM Non-interleaved memory that can be quickly accessed by processors residing on the same cell
as the memory. This is the same concept as CLM.
socket local
memory
See SLM
start virtual
machines
To start a virtual machine that has been booted before.
See also boot virtual machines.
storage unit A file, DVD, disk, or logical volume on the VSP that is used by the virtual machines running on
the VSP.
symmetric
Serviceguard
configuration
A cluster configuration in which the nodes share access to the same storage and network devices.
TOC Transfer of control
Transfer of control See TOC.
virtual console The virtualized console of a virtual machine that emulates the functionality of the Management
Processor interface for HP Integrity servers. Each virtual machine has its own virtual console from
which the virtual machine can be powered on or off and booted or shut down, and from which
the guest OS can be selected.
virtual device An emulation of a physical device. This emulation, used as a device by a virtual machine,
effectively maps a virtual device to an entity (for example, a DVD) on the VSP.
virtual machine Virtual hardware system. Also called VM.
virtual machine
application
The executable program on the VSP that manifests the individual virtual machine. The program
communicates with the loadable drivers based on information in the guest-specific configuration
file, and it instantiates the virtual machine.
virtual machine
console
The user-mode application that provides console emulation for virtual machines. Each instance
of the virtual machine console represents one console session for its associated virtual machine.
virtual machine
host
See VSP.
Virtual Machine
Manager (VMM)
The management application responsible for managing and configuring HP Integrity Virtual
Machines.
virtual machine
migration
Migration of a virtual machine from one VSP system to another by using the Integrity VM command
hpvmmigrate. Do not use this command for virtual machine packages.
virtual machine
package
A virtual machine that is configured as a Serviceguard package.
virtual network A LAN that is shared by the virtual machines running on the same VSP or in the same Serviceguard
cluster.
virtual switch See vswitch.
Virtualization
Services Platform
See VSP.
VM See Virtual machine.
vNIC Virtual network interface card (NIC). The network interface that is accessed by guest applications.
vPar Virtual partition. A partition that is created and managed from the VSP. A vPar is assigned CPU
cores, and memory.
VSP Virtualization Services Platform. The management platform for creating and managing virtual
partitions. Provides both command-line interface and graphical user interface for configuring and
managing vPars.
vswitch Virtual switch. A component in the guest virtual network. By associating the vswitch with a physical
working LAN on the VSP, you provide the guest with the capability of communicating outside the
localnet.
