Msvm_ResourcePool class

[アーティクル]
05/31/2018

Describes a type of virtual resource available for use in virtual systems. The resource pool aggregates physical resources and is used to allocate resources to virtual systems. In Hyper-V, all resource pools are primordial, and there is exactly one pool for each specific type of resource which may be allocated to a virtual machine.

The following syntax is simplified Managed Object Format (MOF) code, and it includes all of the inherited properties.

Members

The Msvm_ResourcePool class has these types of members:

Properties

Properties

The Msvm_ResourcePool class has these properties.

AllocationUnits

Data type: string
Access type: Read-only

The units of allocation used by the resource pool. This property is inherited from CIM_ResourcePool and it is set to "Megabyte".

Capacity

Data type: uint64
Access type: Read-only

The maximum amount (in units of AllocationUnits) of active reservations that the resource pool can support. This property is inherited from CIM_ResourcePool.

Caption

Data type: string
Access type: Read-only
Qualifiers: MaxLen (64)

A short textual description (one-line string) of the object. This property is inherited from CIM_ManagedElement and its value depends on the type of resource being aggregated.

Description

Data type: string
Access type: Read-only

A textual description of the object. This property is inherited from CIM_ManagedElement.

ElementName

Data type: string
Access type: Read-only

A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of the CIM_ManagedSystemElement class is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. This property is inherited from CIM_ManagedElement.

HealthState

Data type: uint16
Access type: Read-only

The current health of the element. This property is inherited from CIM_ManagedSystemElement and it is always set to 5 (OK).

OK (5)

The element is fully functional and operates within normal operational parameters and without error.

InstallDate

Data type: datetime
Access type: Read-only
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")

The date and time at which the virtual system was created. This property is inherited from CIM_ManagedSystemElement.

InstanceID

Data type: string
Access type: Read-only
Qualifiers: Key

A unique identifier for this resource pool. This property is inherited from CIM_ResourcePool and it is always set to "Microsoft:GUID\Root".

Name

Data type: string
Access type: Read-only
Qualifiers: MaxLen (1024)

The label by which the object is known. When subclassed, this property can be overridden to be a key property. This property is inherited from CIM_ManagedSystemElement.

OperationalStatus

Data type: uint16 array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")

The current status of the element. This property is inherited from CIM_ManagedSystemElement and it is always set to 2 (OK). Hyper-V will only ever use the first element of this array.

OtherResourceType

Data type: string
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_ResourcePool.ResourceType")

A string that describes the resource type when a well-defined value is not available and ResourceType is set to 0 ("Other"). This property is inherited from CIM_ResourcePool and it is set to NULL.

PoolID

Data type: string
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_ResourceAllocationSettingData.PoolId")

This value is referenced by the CIM_ResourceAllocationSettingData instances which were allocated from this pool. This property is inherited from CIM_ResourcePool and it is always set to "Microsoft:GUID\Root".

Primordial

Data type: boolean
Access type: Read-only

If True, "Primordial" indicates whether this resource pool is the base from which resources are drawn and returned in the activity of resource management. Being primordial means that this resource pool shall not be created or deleted by consumers of this model. However, other actions, modeled or not, may affect the characteristics or size of primordial resource pools. This property is inherited from CIM_ResourcePool.

Reserved

Data type: uint64
Access type: Read-only

The current reservations (in units of AllocationUnits) spread across all active allocations from this pool. In a hierarchical configuration, this represents the sum of all descendant resource pool current reservations. This property is inherited from CIM_ResourcePool.

ResourceSubType

Data type: string
Access type: Read-only

A string that describes an implementation specific sub-type for this pool. For example, this may be used to distinguish different models of the same resource type. This property is inherited from CIM_ResourcePool.

ResourceType

Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_ResourceAllocationSettingData.OtherResourceType")

The type of resource this resource pool may allocate. This property is inherited from CIM_ResourcePool and it is set to 4 ("Memory").

Status

Data type: string
Access type: Read-only
Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

This property is inherited from CIM_ManagedSystemElement but it is not used.

StatusDescriptions

Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.OperationalStatus")

Strings that describe the various OperationalStatus array values. This property is inherited from CIM_ManagedSystemElement and it is always set to "OK". Hyper-V will only ever use the first element of this array.

Remarks

Access to the Msvm_ResourcePool class might be restricted by UAC Filtering. For more information, see User Account Control and WMI.
