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 using the ModifyServiceSettings method of the Msvm_VirtualSystemManagementService class. 
- 
- 
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 it is set to "Virtual System Management Service". 
- 
- 
DefaultExternalDataRoot 
-  - 
Data type: string 
- 
Access type: Read-only 
- 
Qualifiers: ModelCorrespondence ("Msvm_ComputerSystem.ExternalDataRoot") 
 The default external data root. By default, "root\ProgramData\Microsoft\Windows\Virtualization". This is a read-only property, but it can be changed using the ModifyServiceSettings method of the Msvm_VirtualSystemManagementService class. 
- 
- 
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 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 and it is set to "Settings for the Virtual System Management Service". 
- 
- 
ElementName 
-  - 
Data type: string 
- 
Access type: Read-only 
- 
Qualifiers: Required 
 A user-friendly name for the object. This property is inherited from CIM_ManagedElement and it is set to "Virtual System Management Service". Changing this property will change the ElementName property of the associated CIM_LogicalDevice derivative. 
- 
- 
InstanceID 
-  - 
Data type: string 
- 
Access type: Read-only 
- 
Qualifiers: Key 
 This property is inherited from CIM_SettingData and it is set to "Microsoft:host", where host is the NetBIOS name of the hosting computer system. 
- 
- 
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 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 using the ModifyServiceSettings method of the Msvm_VirtualSystemManagementService class. 
- 
- 
NumaSpanningEnabled 
-  - 
Data type: boolean 
- 
Access type: Read-only 
 Specifies if memory can be allocated from remote nonuniform memory access (NUMA) nodes when starting a VM or when assigning memory to a VM by dynamic memory. This can be one of the following values. Value Meaning - 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 VM. This is a read-only property, but it can be changed by using the ModifyServiceSettings method of the Msvm_VirtualSystemManagementService class. Windows Server 2008 R2: Reserved for future use. Note that this behavior has changed with Windows Server 2008 R2 with SP1. Windows Server 2008: The NumaSpanningEnabled property is not available before Windows Server 2008 R2.
