Msvm_VirtualSystemManagementServiceSettingData class

  • Article

Represents the settings for the virtualization service present on a single host system. The properties for this class cannot be modified directly. The client must call the ModifyServiceSettings method of the Msvm_VirtualSystemManagementService class to modify any of these properties.

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

Properties

The Msvm_VirtualSystemManagementServiceSettingData class has these properties.

BiosLockString

Data type: string

Access type: Read-only

Qualifiers: Maxlen (32)

Used by OEMs to allow BIOS-locked Windows operating systems to run in the virtual machine. This string must be exactly 32 characters in length.

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

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

A short textual description of the object.

This property is inherited from CIM_ManagedElement.

CurrentWWNNAddress

Data type: string

Access type: Read-only

The world wide node name (WWNN) address for dynamically generated world wide name addresses used for synthetic host bus adapters.

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

DefaultExternalDataRoot

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("Msvm_VirtualSystemSettingData.ConfigurationDataRoot")

The default external data root. By default, "root\ProgramData\Microsoft\Windows\Virtualization".

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

DefaultVirtualHardDiskCachingMode

Data type: uint16

Access type: Read-only

Indicates whether in-memory file caching should be used for disks by default. This value can be overridden on a per-disk basis in the CachingMode property of the Msvm_StorageAllocationSettingData class.

The possible values are:

Unknown (0)

No Caching (3)

Cache Sharable Parents (4)

DefaultVirtualHardDiskPath

Data type: string

Access type: Read-only

The default virtual hard disk path. By default, "root\Users\Public\Documents\Virtual Hard Disks".

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

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

The user-friendly name for an instance of this class. In addition, the user-friendly name can be used as an index for a search or query. The name does not have to be unique within a namespace.

This property is inherited from CIM_SettingData.

EnhancedSessionModeEnabled

Data type: boolean

Access type: Read-only

Indicates whether enhanced session mode is permitted on the server. true indicates permitted, otherwise false.

HbaLunTimeout

Data type: uint32

Access type: Read-only

Specifies the amount of time that the synthetic Fibre Channel virtual device will wait for a logical unit number (LUN) to appear before starting a virtual machine.

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

InstanceID

Data type: string

Access type: Read-only

Qualifiers: Key

Uniquely identifies an instance of this class within the scope of the containing namespace.

[!Important]

In order to ensure uniqueness within the namespace, the value of the InstanceID property should be constructed in the following pattern: OrgID:LocalID

  • OrgID must include a copyrighted, trademarked or otherwise unique name that is owned by the business entity that defines the InstanceID property, or be a registered ID that is assigned by a recognized global authority.
  • OrgID must not contain a colon. The first colon in InstanceID must be between the OrgID andLocalID.
  • LocalID is chosen by the business entity and should not be re-used to identify different underlying real-world elements.
  • If the above pattern is not used, the defining entity must assure that the resultant InstanceID value is not re-used across any InstanceID properties that are produced by this provider or other providers for this namespace.
  • For DMTF defined instances, the pattern must be used with the OrgID set to "CIM".

This property is inherited from CIM_SettingData.

MaximumMacAddress

Data type: string

Access type: Read-only

The maximum MAC address for dynamically generated MAC addresses.

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

MaximumWWPNAddress

Data type: string

Access type: Read-only

The maximum world wide port name (WWPN) address for dynamically generated world wide name addresses used for synthetic host bus adapters.

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

MinimumMacAddress

Data type: string

Access type: Read-only

The minimum MAC address for dynamically generated MAC addresses.

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

MinimumWWPNAddress

Data type: string

Access type: Read-only

The minimum world wide port name address for dynamically generated world wide name addresses used for synthetic host bus adapters.

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

NumaSpanningEnabled

Data type: boolean

Access type: Read-only

Specifies whether memory can be allocated from remote nonuniform memory access (NUMA) nodes when starting a virtual machine or when assigning memory to a virtual machine by dynamic memory. This can be one of the following values.

True

Memory can be allocated from both local and remote NUMA nodes.

False

Memory can be allocated only from the NUMA node assigned to the virtual machine.

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

PrimaryOwnerContact

Data type: string

Access type: Read-only

Qualifiers: Maxlen (256), Mappingstrings ("MIF.DMTF|General Information|001.4")

The name of the primary system owner. By default, "Administrators". This value may not exceed 64 characters in length.

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

PrimaryOwnerName

Data type: string

Access type: Read-only

Qualifiers: Maxlen (64), Mappingstrings ("MIF.DMTF|General Information|001.3")

The name of the primary system owner. By default, "Administrators". This value may not exceed 64 characters in length.

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