PowerShell shutdown all running Hyper-V VMs

PowerShell Script that shuts down all running virtual machines on named Hyper-V server. It shuts them down one at a time waiting while a VM shuts down before shutting down the next. Remember to substitute your <servername>. Quick way to shutdown the test environment at the end of the day.

$runningVM=Get-VM –ComputerName <servername> | Where-Object {$_.State -eq 'Running'}

foreach($cn in $runningVM){
Write-Host "Shutting down $($cn.name)"
stop-vm $cn.name -force
}

Add the following lines to shut down the Hyper-v server

Write-Host "Shutting down Hyper-V server”

Stop-Computer –computername <servername> –force

Start Virtual Machine when you start Hyper-V

I have a Virtual Machine that I want to start automatically when I start the Hyper-V server in my test environment. How would I do/undo this with PowerShell.

Start a VM called vm01 automatically

SET-VM –name vm01 –AutomaticStartAction Start

Prevent a VM called vm01 from starting automatically

SET-VM –name Vm01 –AutomaticStartAction Nothing

Wild cards a permissible – every VM that start with b

SET-VM –name b* –AutomaticStartAction Start
