Disable (Hyper-V) PowerShell Modules

[Tocano]

I have a utility server that I use to administer our vSphere environment. I use PowerCLI pretty heavily. We also have a Hyper-V environment and are starting to increase our scripting and automating of that as well.

The problem is that I'm getting cmdlet conflicts.

> gcm -type cmdlet,function,alias | group name | where { $_.count -gt 1 }

(shows about 20 conflicting commands between Hyper-V and PowerCLI (New-VM, Start-VM, Stop-VM, Get-VM, Export-VM, Get-VMHost, etc).

I don't necessarily want to completely eliminate the Hyper-V module from the server as we are starting to use it and that looks to increase. If there was a way to disable it whenever I am starting PowerCLI or running a PowerCLI script, that would probably be the best option.

I have tried things like:

> (Get-Module -Name Hyper-V) | Remove-Module -Force

But while I get no error, it doesn't seem to remove the cmdlets. I get the same results with the gcm command and I continue to get errors due to conflicts.

Any help would be appreciated.

Thank you

In PowerShell v3 and higher modules that are located in any of the directories defined in the $PSModulePath variable are autoloaded.

See paragraph 2 in this document.

You can disable this behavior by using the following setting

$PSMmoduleAutoloadingPreference="none" 

You could do something like this in your scripts

$defaultAutoLoad = $PSMmoduleAutoloadingPreference
$PSMmoduleAutoloadingPreference = "none"
Remove-Module -Name Hyper-V

# Do your PowerCLI stuff


# End of the PowerCLI stuff

$PSMmoduleAutoloadingPreference = $defaultAutoLoad

The drawback of this method is that you will have to load other modules, you would require, explicitly in the script with the Import-Module cmdlet.
