All Hosts host group
The default host group, which contains all host groups and all virtual machine hosts that are managed by Virtual Machine Manager.
The process by which a virtual machine is automatically deployed on the most suitable host that is available in a host group. Automatic placement occurs when self-service users create virtual machines and when an administrator migrates a virtual machine to a host group by using the drag-and-drop method.
See also: virtual machine placement
A point-in-time snapshot of a virtual machine that enables an administrator to roll the virtual machine back to its state at the moment when the checkpoint was created.
child host group
A host group contained within another host group, which can inherit host reserve settings and virtual machine permissions from its parent host group. All host groups are child host groups of the root host group, All Hosts.
The process by which a new virtual machine is created from an existing virtual machine. The new virtual machine has the same identity as the source machine.
A command-line element, formatted as a verb-noun pair, used to manipulate objects in Windows PowerShell.
A name with as many as 15 characters that identifies a computer to the network. The computer name cannot be the same as any other computer or domain name in the network. For a virtual machine, the computer name is the hostname assigned to the guest operating system.

Domain Name System (DNS)
A technology that translates Internet address names into numerical addresses (IP addresses) so that the address can be found over the Internet. For example, if you type www.microsoft.com into a Web browser, the name is translated into a numerical address and that address is used to connect you to the Microsoft Web site.
guest operating system profile
In Virtual Machine Manager, a library resource containing the most common settings from a Sysprep.inf file, including the computer name and domain or workgroup settings, which can be applied to a virtual machine template.
In Virtual Machine Manager, a library resource containing hardware specifications that can be applied to a new virtual machine or a virtual machine template. A hardware profile can contain specifications for CPU, memory, network adapters, a DVD drive, a floppy drive, COM ports, and the priority given the virtual machine when allocating resources on a virtual machine host.
See definition for: virtual machine host
A feature of Virtual Machine Manager that enables administrators to create custom groups of virtual machine hosts for ease of monitoring and management. Host groups can be used to determine the resources reserved for host operating systems and to administer virtual machine self-service.
A sequence of host group names that specifies the location of a virtual machine host or host group within the hierarchy of host groups. All host paths begin with the root host group, All Hosts. For example, the host path All Hosts\New York\Site21\VMHost05 indicates that the host VMHost05 belongs to the host group Site21, which is a child host group of the host group New York.
A rating, consisting of zero through five stars, that is assigned to each host during virtual machine placement to indicate the host’s suitability for hosting the virtual machine. The host rating is based on the virtual machine's hardware and software requirements and anticipated resource usage. Host ratings also take into consideration the placement goal: either resource maximization on hosts or load balancing among hosts. The metrics for rating hosts can be customized for Virtual Machine Manager and for individual virtual machines during placement.
The percentage of CPU, memory, disk space, disk I/O, and network throughput that are set aside for the use of the host operating system on the physical host computer. A virtual machine cannot be placed on a host if the virtual machine’s resource requirements cannot be met without using host reserves.
An informal term for a disk image (.iso file) of an ISO 9960 file system or any optical disk image. The disk image contains data files and all file system metadata.

A series of steps that are performed sequentially to complete an action. In Virtual Machine Manager, each job is represented by one or more cmdlets in the Windows PowerShell – Virtual Machine Manager command shell. A complex action in Virtual Machine Manager, such as performing a physical-to-virtual machine conversion, may incorporate a series of jobs known as a "job group."

See definition for: Virtual Machine Manager library
A property of a library server that can be used to sort and group library servers.
The process by which all files stored on library shares are indexed in Virtual Machine Manager and file-based resources are updated in the Virtual Machine Manager library.
A server that makes shares available to store resources in the Virtual Machine Manager library. The library is managed centrally through the Library view of the Virtual Machine Manager Administrator Console. A Virtual Machine Manager agent installed on the library server provides metadata to Virtual Machine Manager about the shares that have been identified as library shares and the resources on those shares.
See also: Virtual Machine Manager library
A share on a library server, which stores resources that are used to create virtual machines.
One of two placement goals during virtual machine placement. When load balancing is the goal, the suitability of each virtual machine host is rated based on the intent to minimize the processing load on any one host.
See also: resource maximization, placement defaults
A virtual machine host that is managed by Virtual Machine Manager.
See definition for: virtual machine migration
See definition for: physical-to-virtual machine conversion (P2V)
parent host group
A host group that contains another host group, which is known as a "child host group."
physical-to-virtual machine conversion (P2V conversion)
The process by which a functioning physical computer is "converted" to an identical, or nearly identical, virtual machine. During a P2V conversion, disk images of the hard disks on the physical computer are created and formatted as virtual hard disks (.vhd files) for use in the new virtual machine. The new virtual machine has the same computer identity as the physical computer on which it is based.
See definition for: virtual machine placement
One of two placement goals during virtual machine placement. When resource maximization is the goal, the suitability of each virtual machine host is rated based on the purpose of consolidating multiple low-utilization workloads on a single host. Virtual machine placement in these cases involves determining the capacity limits for a particular host and placing virtual machines on that host until the limits are reached.
See also: load balancing, placement defaults
root host group
The default host group, All Hosts, which is the parent host group of all hosts and host groups in Virtual Machine Manager. The name of the root host group can be assigned during Setup.
A collection of configuration settings that determine the conditions under which a user or group can manage their own virtual machines through virtual machine self-service. The self-service policy assigns virtual machine permissions and templates. Self-service policies are configured for a host group.
