Msvm_ResourcePool class
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
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.
