GetVirtualSystemImportSettingData method of the Msvm_VirtualSystemManagementService class

Returns an instance of the Msvm_VirtualSystemImportSettingData class.

Syntax

uint32 GetVirtualSystemImportSettingData(
  [in]  string                              ImportDirectory,
  [out] Msvm_VirtualSystemImportSettingData ImportSettingData,
  [out] CIM_ConcreteJob                 REF Job
);

Parameters

ImportDirectory [in]

Type: string

The fully qualified path to the directory that represents a previously exported virtual computer system. This file must have been generated by a previous call to the ExportVirtualSystem or ExportVirtualSystemEx methods.

ImportSettingData [out]

Type: Msvm_VirtualSystemImportSettingData

An instance of the Msvm_VirtualSystemImportSettingData class that represents the virtual system import setting data.

Job [out]

Type: CIM_ConcreteJob

An optional reference that is returned if the operation is executed asynchronously. If present, the returned reference to an instance of the CIM_ConcreteJob class can be used to monitor progress and to obtain the result of the method.

Return value

Type: uint32

If this method is executed synchronously, it returns 0 if it succeeds. If this method is executed asynchronously, it returns 4096 and the Job output parameter can be used to track the progress of the asynchronous operation. Any other return value indicates an error. The return value can be one of the following values.

Completed with No Error (0)

Method Parameters Checked - Job Started (4096)

Failed (32768)

Access Denied (32769)

Not Supported (32770)

Status is unknown (32771)

Timeout (32772)

Invalid parameter (32773)

System is in use (32774)

Invalid state for this operation (32775)

Incorrect data type (32776)

System is not available (32777)

Out of memory (32778)

Remarks

Access to the Msvm_VirtualSystemManagementService class might be restricted by UAC Filtering. For more information, see User Account Control and WMI.

Examples

The following C# sample imports a virtual system. The referenced utilities can be found in Common Utilities for the Virtualization Samples.
