Members

The Msvm_ResourceAllocationSettingData class has these types of members:

Properties

The Msvm_ResourceAllocationSettingData class has these properties.

Address

Data type: string

Access type: Read-only

The address of the resource. This property is inherited from CIM_ResourceAllocationSettingData.

This is a read-only property, but if the ResourceType property is 20 (Graphics controller) it can be changed using the ModifyVirtualSystemResources method of the Msvm_VirtualSystemManagementService class.

AllocationUnits

Data type: string

Access type: Read-only

The units of allocation used by the Reservation and Limit properties. This property is inherited from CIM_ResourceAllocationSettingData.

AutomaticAllocation

Data type: boolean

Access type: Read-only

Indicates whether the resource will be automatically allocated. This property is inherited from CIM_ResourceAllocationSettingData.

AutomaticDeallocation

Data type: boolean

Access type: Read-only

Indicates whether the resource will be automatically de-allocated. This property is inherited from CIM_ResourceAllocationSettingData.

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.

Connection

Data type: string array

Access type: Read-only

The device to which this resource is connected. This property is inherited from CIM_ResourceAllocationSettingData.

This is a read-only property, but if either (1) the ResourceType property is 17 (Serial port) or (2) the ResourceType property is 21 (Storage Extent) and the ResourceSubType property is "Microsoft Virtual Hard Disk" then it can be changed using the ModifyVirtualSystemResources method of the Msvm_VirtualSystemManagementService class.

ConsumerVisibility

Data type: uint16

Access type: Read-only

The consumer's visibility to the allocated resource. This property is inherited from CIM_ResourceAllocationSettingData.

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

Qualifiers: Required

A user-friendly name for the object. This property is inherited from CIM_SettingData. Changing this property will change the element name of the associated logical device derivative.

This is a read-only property, but it can be changed using the ModifyVirtualSystemResources method of the Msvm_VirtualSystemManagementService class.

HostResource

Data type: string array

Access type: Read-only

Qualifiers: HyperVEmbeddedInstance ("CIM_LogicalDevice")

Only one host resource may be assigned to each device in the virtual machine, so only the first element of this array may be set. For devices that support this feature, set the first element of the HostResource array to contain a reference to the underlying host resource which is to be assigned. This property is inherited from CIM_ResourceAllocationSettingData.

This is a read-only property, but if the ResourceType property is 22 (Disk) and the ResourceSubType property is "Microsoft Physical Disk Drive" then it can be changed using the ModifyVirtualSystemResources method of the Msvm_VirtualSystemManagementService class.

InstanceID

Data type: string

Access type: Read-only

Qualifiers: Key

For instances associated with a virtual system, this will be "Microsoft:GUID\device-specific data". For instances which define potential settings for a virtual system, this will be "Microsoft:Definition\GUID\Type", where Type can be one of "Maximum", "Minimum", "Default", or "Increment". This property is inherited from CIM_SettingData.

Limit

Data type: uint64

Access type: Read-only

The maximum amount of corresponding host resources which may be consumed by the virtual system. This property is inherited from CIM_ResourceAllocationSettingData.

MappingBehavior

Data type: uint16

Access type: Read-only

Specifies how this resource maps to underlying resources. This property is inherited from CIM_ResourceAllocationSettingData.

Unknown (0)

Not Supported (1)

Dedicated (2)

Soft Affinity (3)

OtherResourceType

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourceAllocationSettingData.ResourceType")

A string that describes the resource type when a well-defined value is not available and ResourceType has the value 1(Other). This property is inherited from CIM_ResourceAllocationSettingData.

Parent

Data type: string

Access type: Read-only

The parent of the resource. This property is inherited from CIM_ResourceAllocationSettingData.

PoolID

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourcePool.PoolId")

The identifier of the resource pool from which this resource was allocated. For instances associated with a virtual system, this will be "Microsoft:GUID\device-specific data". For instances which define potential settings for a virtual system, this will be "Microsoft:Definition\GUID\Type", where Type can be one of "Maximum", "Minimum", "Default", or "Increment". This property is inherited from CIM_ResourceAllocationSettingData.

Reservation

Data type: uint64

Access type: Read-only

The amount of CPU resources that are reserved for use by the virtual system. These resources are guaranteed to be available for consumption by the virtual system. This property is inherited from CIM_ResourceAllocationSettingData.

ResourceSubType

Data type: string

Access type: Read-only

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

ResourceType

Data type: uint16

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourceAllocationSettingData.OtherResourceType")

The type of resource this allocation setting represents. This property is inherited from CIM_ResourceAllocationSettingData.

VirtualQuantity

Data type: uint64

Access type: Read-only

The total number of cores in the virtual system. This property is inherited from CIM_ResourceAllocationSettingData.

VirtualSystemIdentifiers

Data type: string array

Access type: Read-only

Qualifiers: ArrayType ("Indexed")

A free-form string array of identifiers of this resource presented to the virtual computer system's operating system. These values are used only if the ResourceType property is set to 6 (Parallel SCSI HBA) and the ResourceSubType property is set to "Microsoft Synthetic SCSI Controller". This property is set to "GUID".

This is a read-only property, but it can be changed using the ModifyVirtualSystemResources method of the Msvm_VirtualSystemManagementService class.

Windows Server 2008: The VirtualSystemIdentifiers property is not supported until Windows Server 2008 R2.

Weight

Data type: uint32

Access type: Read-only

An integer defining the weight for each virtual machine processor. After all reserves have been met, the remaining physical processor capacity of the hosting platform will be allocated to virtual systems based on their relative weights. This property is inherited from CIM_ResourceAllocationSettingData.

Range: 0 1000

Remarks

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