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

Glossary
This glossary defines the terms and abbreviations as they are used in the Integrity VM
product documentation.
Accelerated
Virtual
Input/Output
See AVIO
adoptive node The cluster member where the package starts after it fails over.
APA Auto Port Aggregation. An HP-UX software product that creates link aggregates, often called
“trunks,” which provide a logical grouping of two or more physical ports into a single “fat
pipe”. This port arrangement provides more data bandwidth than would otherwise be available.
application A collection of processes that perform a specific function. In the context of virtual machine
clusters, an application is any software running on the guest.
asymmetric
Serviceguard
configuration
A cluster configuration in which the cluster nodes do not have access to the same physical
storage and network devices.
autoboot A characteristic of a virtual machine whereby it is set to start whenever Integrity VM starts.
Virtual machines can be set to either auto or manual boot using the -b option to the
hpvmcreate, hpvmmodify, hpvmmigrate, or hpvmclone commands.
available
resources
Processors, memory, and I/O resources that are not assigned to a virtual machine. These resources
are available to be used in new partitions or can be added to existing partitions.
AVIO Accelerated Virtual Input/Output. An I/O protocol that improves virtual I/O performance for
network and storage devices used within the Integrity VM environment. The protocol also
enables support for a greater number of virtual I/O devices per guest. Special drivers are required
on both the VM host and guests. Participating guests must include a virtual I/O device configured
to use the AVIO protocol.
backing store The physical device on the VM Host that is allocated to guests, such as a network adapter, disk,
or file.
BMC Baseboard Management Controller. The Management Processor (MP) console for Intel® Itanium
systems.
boot virtual
machines
To load a virtual machine's operating system and start it. Once a virtual machine has been
configured with an operating system, it is considered a guest, and is started automatically when
Integrity VM starts, or manually using the hpvmstart command.
See also start virtual machines.
captive virtual
console account
A special-purpose user account created on the VM Host for each guest administrator or operator.
cluster Two or more systems configured together to host workloads. Users are unaware that more than
one system is hosting the workload.
cluster member A cluster node that is actively participating in the Serviceguard cluster.
cluster node A system (VM Host or guest) configured to be a part of a Serviceguard cluster.
dedicated device A pNIC or storage unit that is dedicated to a specific virtual machine. A dedicated device cannot
be used by multiple virtual machines.
distributed guests Guests that has been configured as a Serviceguard package.
EFI Extensible Firmware Interface. The boot firmware for all HP Integrity systems.
entitlement The amount of a system resource (for example, a processor) that is guaranteed to a virtual
machine. The actual allocation of resources to the virtual machine can be greater or less than
its entitlement, depending on the virtual machine's demand for processor resources and the
overall system processor load.
event log Information about system events. An event log indicates what event has occurred, when and
where it happened, and its severity (alert level). Event logs do not rely on normal I/O operation.
