HP Integrity Virtual Machines Installation, Configuration, and Administration Version A.03.50

PMAN Platform Manager. See VM Host.
pNIC Physical network interface card.
primary node The cluster member on which a failed-over package was originally running.
redundancy A method of providing high availability that uses mltiple copies of storage or network units to
ensure services are always available (for example, disk mirroring).
restricted device A physical device that can be accessed only by the VM Host system. For example, the VM Host
boot device should be a restricted device.
Serviceguard Serviceguard allows you to create high-availability clusters of HP 9000 or HP Integrity servers.
Many customers using Serviceguard want to manage virtual machines as Serviceguard packages.
A Serviceguard package groups application services (individual HP-UX processes) together
and maintains them on multiple nodes in the cluster, making them available for failover.
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.
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 VM Host that is used by the virtual machines running
on the VM Host.
symmetric
Serviceguard
configuration
A cluster configuration in which the nodes share access to the same storage and network devices.
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, s a DVD) on the VM Host.
virtual machine Virtual hardware system. Also called VM.
virtual machine
application
The executable program on the VM Host 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 VM Host.
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 VM Host 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 VM Host or in the same
Serviceguard cluster.
virtual switch See vswitch.
VM See Virtual machine.
VM Host The virtual machine host system.
vNIC Virtual network interface card (NIC). The network interface that is accessed by guest applications.
vswitch Virtual switch. A component in the guest virtual network. By associating the vswitch with a
physical working LAN on the VM Host, you provide the guest with the capability of
communicating outside the localnet.
