Why are there two Hyper-V PowerShell modules in Windows 10?

  • [アーティクル]

If you use get-module in PowerShell on Windows 10 - you will see that there are now two Hyper-V PowerShell modules:

There is an important reason for this.

In the past we have never supported using Hyper-V PowerShell on one version of Windows to manage a different version of Hyper-V on a remote computer.  For many scenarios this has "just worked" - but it has not been something that we actively supported and verified.  At the same time - we have been hearing feedback that people want this scenario to work.  To enable this in Windows 10 - we have started versioning our PowerShell module to provide cross version compatibility.  If you need to remotely manage a Windows 8.1 / Windows Server 2012 R2 instance of Hyper-V - you should load the v1.1 Hyper-V PowerShell module.  If you are remotely (or locally) managing Windows 10 / Windows Server 2016 - you should use the v2.0 PowerShell module.

By default, the v2.0 module will get loaded if you just run a Hyper-V Cmdlet - but you can easily remove and import the right module for the system that you want to manage.

Cheers,
Ben

    Yes and with this script you can see, what's the difference between the two versions, just open a new Powershell prompt and insert: Import-Module Hyper-V -RequiredVersion 1.1 $cV1 = Get-Command -Module Hyper-V PS> Remove-Module Hyper-V Import-Module Hyper-V -RequiredVersion 2.0.0.0 $cV2 = Get-Command -Module Hyper-V compare $cv1 $cv2 Got it from: newyear2006.wordpress.com/.../umgang-mit-verschiedenen-versionen-von-powershellmodulen-und-ermittlung-von-unterschieden

    When I try to use the 1.1 version for managing a Hyper-V 2012 R2 server I get this. Anyone ever see this?Import-Module -name Hyper-V -RequiredVersion 1.1Import-Module : The following error occurred while loading the extended type data file: Error in TypeData "Microsoft.HyperV.PowerShell.VMReplicationServer": The member AllowAnyServer is already present.

      do you see the require module when you do get-module -name hyper-v -listavailable? Are you on Windows 10/2016 with Hyper-V powershell tools installed?
