Properties

The Msvm_VirtualSystemManagementService class defines the following properties.

Caption

Data type: string
Access type: Read-only

A short textual description (one-line string) of the object. This property is inherited from CIM_ManagedElement and it is always set to "Virtual System Management Service".

CreationClassName

Data type: string
Access type: Read-only

The name of the class or subclass used in the creation of an instance. This property is inherited from CIM_Service and it is always set to "Msvm_VirtualSystemManagementService".

Description

Data type: string
Access type: Read-only

A textual description of the object. This property is inherited from CIM_ManagedElement and it is always set to "Service for creating, manipulating, and managing virtual systems".

ElementName

Data type: string
Access type: Read-only

A user-friendly name for the object. This property is inherited from CIM_ManagedElement and it is always set to "Virtual System Management Service".

EnabledDefault

Data type: uint16
Access type: Read-only

An administrator's default or startup configuration for the enabled state of an element. This property is inherited from CIM_EnabledLogicalElement and it is always set to 2 (Enabled).

EnabledState

Data type: uint16
Access type: Read-only

The enabled and disabled states of an element. It can also indicate the transitions between these requested states. This property is inherited from CIM_EnabledLogicalElement and it is always set to 2 (Enabled).

HealthState

Data type: uint16
Access type: Read-only

The current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely non-functional. This property is inherited from CIM_ManagedSystemElement and it is always set to 5 (OK).

InstallDate

Data type: datetime
Access type: Read-only

The date and time the virtual machine configuration was created. This property is inherited from CIM_ManagedSystemElement.

Name

Data type: string
Access type: Read-only

The label by which the object is known. This property is inherited from CIM_Service and it is always set to "vmms".

OperationalStatus

Data type: uint16 array
Access type: Read-only

The current statuses of the object. This property is inherited from CIM_ManagedSystemElement and each array element is always set to 2 (OK).

OtherEnabledState

Data type: string
Access type: Read-only

A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1. This property is inherited from CIM_EnabledLogicalElement and it is always set to NULL.

PrimaryOwnerContact

Data type: string
Access type: Read-only

Any information about how the primary owner of the service can be reached (for example, phone number, e-mail address, and so on). This property is inherited from CIM_Service and it is always set to NULL.

PrimaryOwnerName

Data type: string
Access type: Read-only

The name of the primary owner for the service, if one is defined. The primary owner is the initial support contact for the service. This property is inherited from CIM_Service and it is always set to NULL.

RequestedState

Data type: uint16
Access type: Read-only

The last requested or desired state for the element. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. A particular instance of CIM_EnabledLogicalElement might not support RequestedStateChange. If this occurs, the value 12 ("Not Applicable") is used. This property is inherited from CIM_EnabledLogicalElement and it is always set to 12 (Not Applicable).

Started

Data type: boolean
Access type: Read-only

Indicates whether the service is currently running. This property is inherited from CIM_Service and it is always set to TRUE.

StartMode

Data type: string
Access type: Read-only

A string value that indicates whether the service is automatically started by a system, an operating system, or is started only upon request. This property is inherited from CIM_Service and it is always set to NULL.

Status

Data type: string
Access type: Read-only

This property is inherited from CIM_ManagedSystemElement but it is not used.

StatusDescriptions

Data type: string array
Access type: Read-only

Strings that describe the various OperationalStatus array values. This property is inherited from CIM_ManagedSystemElement and each array element is always set to "The service is running normally".

SystemCreationClassName

Data type: string
Access type: Read-only

The scoping system's creation class name. This property is inherited from CIM_Service and it is always set to "Msvm_ComputerSystem".

SystemName

Data type: string
Access type: Read-only

The NetBIOS name of the hosting computer system. This property is inherited from CIM_Service.

TimeOfLastStateChange

Data type: datetime
Access type: Read-only

The date or time when the enabled state of the element last changed. This property is inherited from CIM_EnabledLogicalElement.
