Msvm_VirtualSystemMigrationServiceSettingData class
Represents the settings for the virtual system migration service on a host. The properties for this class cannot be modified directly. The client must call the Msvm_VirtualSystemMigrationService.ModifyServiceSettings method 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_VirtualSystemMigrationServiceSettingData class has these properties.
-
AuthenticationType
-
-
Data type: uint32
-
Access type: Read-only
Specifies the authentication mechanism used for virtual system migration network connections. This is a read-only property, but it can be changed by using the ModifyServiceSettings method of the Msvm_VirtualSystemMigrationService class.
-
-
CredSSP (0)
-
Kerberos (1)
Caption
-
Data type: string
-
Access type: Read-only
A short description of the object. This property is inherited from the CIM_ManagedElement class.
Description
-
Data type: string
-
Access type: Read-only
A description of the object. This property is inherited from CIM_ManagedElement.
ElementName
-
Data type: string
-
Access type: Read-only
A display name for the object. This property is inherited from CIM_SettingData.
EnableCompression
-
Data type: boolean
-
Access type: Read/write
Indicates whether compression of live migration traffic is enabled or disabled. True indicates enabled.
This is a read-only property, but it can be changed by using the ModifyResourceSettings method of the Msvm_VirtualSystemManagementService class.
Windows 8.1: This value is not supported until Windows 8.1 and Windows Server 2012 R2.
EnableSmbTransport
-
Data type: boolean
-
Access type: Read/write
Indicates whether use of SMB as a transport type for transferring VM state between the Hyper-V hosts during virtual system migration is enabled or disabled. True indicates enabled. A higher performance is achieved if RDMA NICs are configured for SMB transport during VM live migration. If EnableSmbTransport value is true, the value of EnableCompression is ignored.
This is a read-only property, but it can be changed by using the ModifyResourceSettings method of the Msvm_VirtualSystemManagementService class.
Windows 8.1: This value is not supported until Windows 8.1 and Windows Server 2012 R2.
EnableVirtualSystemMigration
-
Data type: boolean
-
Access type: Read-only
Specifies whether virtual system migration is enabled or disabled. Storage migration is always enabled. This is a read-only property, but it can be changed by using the ModifyServiceSettings method of the Msvm_VirtualSystemMigrationService class.
InstanceID
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Key
Uniquely identifies an instance of this class. This property is inherited from CIM_ManagedElement.
MaximumActiveStorageMigration
-
Data type: uint32
-
Access type: Read-only
Specifies the maximum number of active storage migrations allowed. This is a read-only property, but it can be changed by using the ModifyServiceSettings method of the Msvm_VirtualSystemMigrationService class.
MaximumActiveVirtualSystemMigration
-
Data type: uint32
-
Access type: Read-only
Specifies the maximum number of active virtual system migrations allowed. This is a read-only property, but it can be changed by using the ModifyServiceSettings method of the Msvm_VirtualSystemMigrationService class.
