Como criar uma VM do Hyper-V com o Powershell DSC e o módulo xHyper-V?

Question

Estou tentando criar uma VM no host do Hyper-V 2016 a partir da minha estação de trabalho do Windows 10 usando o módulo xHyper-V sem muita alegria.

Meu host do Hyper-V chama-se Lithium e meu script DSC está abaixo.

Configuration EndToEndXHyperV_RunningVM
{
    param
    (
        [string[]]$NodeName = 'lithium',

        [Parameter(Mandatory)]
        [string]$VMName,

        [Parameter(Mandatory)] 
        [string]$StartupMemory,

        [Parameter(Mandatory)]
        [string]$MinimumMemory,

        [Parameter(Mandatory)]
        [string]$MaximumMemory,

        [Parameter(Mandatory)]
        [String]$SwitchName,

        [Parameter(Mandatory)]
        [Uint32]$ProcessorCount,

        [ValidateSet('Off','Paused','Running')]
        [String]$State = 'Off',

        [Switch]$WaitForIP
    )

    Import-DscResource –ModuleName 'PSDesiredStateConfiguration'
    Import-DscResource -module xHyper-V

    Node $NodeName
    {
        $NewSystemVHDPath = "\lithium\VHDs-SSD\$($VMName)-System.vhdx"

        # Copy VHD File - hard coded to Windows 2016 Core Eval for now
        File SystemDisk {
            SourcePath = "\lithium\Templates\Windows 2016 Core Template\System.vhdx"
            DestinationPath = $NewSystemVHDPath      
            Type = "File"
            Ensure = "Present"
        }

        # create the generation 2 testVM out of the vhd.
        xVMHyperV NewVM
        {
            Ensure          = 'Present'
            Name            = $VMName
            VhdPath         = $NewSystemVHDPath
            SwitchName      = $SwitchName
            State           = $State
            Path            = $Path
            Generation      = 2
            StartupMemory   = $StartupMemory
            MinimumMemory   = $MinimumMemory
            MaximumMemory   = $MaximumMemory
            ProcessorCount  = $ProcessorCount
            RestartIfNeeded = $true
            WaitForIP       = $WaitForIP 
            DependsOn       = "[File]SystemDisk"
        }
    }
}

Eu concedi acesso à conta da máquina aos compartilhamentos e a cópia do arquivo funciona bem, mas recebo um erro ao adicionar o disco rígido virtual. Alguma idéia?

Answer 1

O problema era que eu estava usando um compartilhamento de arquivos para fazer referência ao VHD, quando deveria ter usado um caminho local. Então a configuração para as unidades é agora:

    $NewSystemVHDPath = "E:\VHDs\$($VMName)-System.vhdx"

    # Copy VHD File - hard coded to Windows 2016 Core Eval for now
    File SystemDisk {
        SourcePath = "D:\Templates\Windows 2016 Core Template\System.vhdx"
        DestinationPath = $NewSystemVHDPath      
        Type = "File"
        Ensure = "Present"
    }

Funciona bem.
