RealizePlannedSystem method of the Msvm_VirtualSystemManagementService class

项目
01/07/2021

Validates the configuration of a planned virtual machine and converts it to a realized virtual machine. Any runtime or saved state files associated with the virtual machine will be copied from the import directory to the virtual machine's data root, if applicable.

Syntax

uint32 RealizePlannedSystem(
  [in]  Msvm_PlannedComputerSystem REF PlannedSystem,
  [out] CIM_ComputerSystem         REF ResultingSystem,
  [out] CIM_ConcreteJob            REF Job
);

Parameters

PlannedSystem [in]

A reference to the Msvm_PlannedComputerSystem instance which is to be converted into a realized virtual machine.

ResultingSystem [out]

If the operation is completed synchronously, a reference to a CIM_ComputerSystem object that represents the resulting realized virtual machine.

Datatype updated from Msvm_ComputerSystem in Windows 10, version 1703.

Job [out]

If the operation is performed asynchronously, this method will return 4096, and this parameter will contain a reference to an object derived from CIM_ConcreteJob.

Return value

This method returns one of the following values.

Completed with No Error (0)
Method Parameters Checked - Job Started (4096)

Examples

The following C# sample uses the RealizePlannedSystem method to realize a planned virtual machine. This code is taken from the Hyper-V planned virtual machines sample. The referenced utilities can be found in Common utilities for the virtualization samples (V2).

Important

To function correctly, the following code must be run on the virtual machine host server, and must be run with Administrator privileges.

/// <summary>
/// Finds the first Planned VM matching pvmName and realizes it.
/// </summary>
/// <param name="pvmName">The name of the PVM to be realized.</param>
/// <returns>The Realized Virtual Machine.</returns>
internal static ManagementObject
RealizePvm(
    string pvmName
    )
{
    ManagementObject vm = null;
    ManagementScope scope = new ManagementScope(@"root\virtualization\v2");

    using (ManagementObject pvm = WmiUtilities.GetPlannedVirtualMachine(pvmName, scope))
    using (ManagementObject managementService = WmiUtilities.GetVirtualMachineManagementService(scope))
    using (ManagementBaseObject inParams =
        managementService.GetMethodParameters("RealizePlannedSystem"))
    {
        inParams["PlannedSystem"] = pvm.Path;

        Console.WriteLine("Realizing Planned Virtual Machine \"{0}\" ({1})...",
                pvm["ElementName"], pvm["Name"]);

        using (ManagementBaseObject outParams =
            managementService.InvokeMethod("RealizePlannedSystem", inParams, null))
        {
            if (WmiUtilities.ValidateOutput(outParams, scope, true, true))
            {
                using (ManagementObject job =
                    new ManagementObject((string)outParams["Job"]))
                using (ManagementObjectCollection pvmCollection =
                    job.GetRelated("Msvm_ComputerSystem",
                        "Msvm_AffectedJobElement", null, null, null, null, false, null))
                {
                    vm = WmiUtilities.GetFirstObjectFromCollection(pvmCollection);
                }
            }
        }
    }

    return vm;
}
