    .Parameter VMHostName
        Specifies the name of the Hyper-V host

    .Parameter HostName
        Specifies the name of the Hyper-V host

    .Parameter VMName
        Specifies the name of the virtual machine to be exported

    .Parameter Path
        Specifies the path to the folder into which the virtual machine is to be exported

    .Parameter AccessAccount
        Specifies the user account that have permission to perform this action

    .Parameter CaptureLiveState
        Specifies how Hyper-V captures the running virtual machine memory state. The acceptable values for this parameter are:
        CaptureCrashConsistentState: Do nothing to handle virtual machine state. CaptureSavedState: Include memory state. CaptureDataConsistentState: Use Production Checkpoint technology.
