systems under Matrix Operating Environment for HP-UX. Other providers of virtual machines
include VMware ESX, VMware ESXi, or Microsoft Hyper-V.
virtual machine
console
The user-mode application that provides console emulation for virtual machines. Each instance
of the virtual machine console is one console session for its associated virtual machine.
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.
VLAN Virtual LAN. Defines logical connectivity instead of the physical connectivity defined by a LAN.
A VLAN provides a way to partition a LAN logically such that the broadcast domain for a VLAN
is limited to the nodes and switches that are members of the VLAN.
VM See virtual machine.
VM Host A server running software such as HP Integrity Virtual Machines, VMware ESX, VMware ESXi,
or Microsoft Hyper-V, that provides multiple virtual machines, each running its own instance of
an operating system.
VM Provider The WBEM services provider for Integrity VM host and guest configuration data. The VM Provider
allows Integrity VM Manager to have visibility to VM Host and guest resources. For VM Manager
VM Host views, the provider gives information about the VM Host and its guests. For VM Manager
virtual machine views, the provider gives information about a particular virtual machine and the
identity of its host.
vswitch Virtual switch. Refers to both a dynamically loadable kernel module (DLKM) and a user-mode
component implementing a virtual network switch. The virtualized network interface cards (NICs)
for guest machines are attached to the virtual switches. 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.
WBEM Web-Based Enterprise Management. A set of web-based information services standards developed
by the Distributed Management Task Force, Inc. A WBEM provider offers access to a resource.
WBEM clients send requests to providers to get information about, and access to, the registered
resources.
