ValidatePlannedSystem method of the Msvm_VirtualSystemManagementService class

Validates the specified planned system. This involves checks of the virtual machine configuration, devices, snapshot configuration, snapshot devices, saved state files and storage files.

Syntax

uint32 ValidatePlannedSystem(
  [in]  Msvm_PlannedComputerSystem REF PlannedSystem,
  [out] CIM_ConcreteJob            REF Job
);

Parameters

PlannedSystem [in]

A reference to an Msvm_PlannedComputerSystem object that represents the planned system to be validated.

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.

Examples

The following C# sample uses the ValidatePlannedSystem method to validate 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).

/// <summary>
/// Finds the first Planned VM matching pvmName and validates it, displaying
/// any warnings produced.
/// </summary>
/// <param name="pvmName">The name of the PVM to be validated.</param>
internal static void
ValidatePvm(
    string pvmName
    )
{
    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("ValidatePlannedSystem"))
    {
        inParams["PlannedSystem"] = pvm.Path;

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

        using (ManagementBaseObject outParams = 
            managementService.InvokeMethod("ValidatePlannedSystem", inParams, null))
        {
            if (WmiUtilities.ValidateOutput(outParams, scope))
            {
                using (ManagementObject job = 
                    new ManagementObject((string)outParams["Job"]))
                {
                    WmiUtilities.PrintMsvmErrors(job);
                }
            }
        }
    }
}
