Artículo
05/31/2018

Represents the virtualization service present on a single host system. Msvm_VirtualSystemManagementService is used to control the definition, modification, and deletion of virtual systems. It also has methods for performing operations on virtual systems, such as cloning, snapshotting, and the importing or exporting of virtual systems. To retrieve per-VM information, use Msvm_ComputerSystem.

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

Properties

The Msvm_VirtualSystemManagementService class has these properties.

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 always set to "Virtual System Management Service".

CreationClassName

Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256)

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/write

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
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.OtherEnabledState")

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).

Enabled (2)

Indicates that the element executes or could execute commands, processes any queued commands, and queues new requests.

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).

OK (5)

The element is fully functional and operates within normal operational parameters and without error.

InstallDate

Data type: datetime
Access type: Read-only
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")

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