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

PS Script will not run from current directory

Your PowerShell script will not run from the current folder.

If you have myscript.ps1 in c:\myfolder and your current directory is c:\myfolder you will find your script will not run.  PowerShell does not search the current folder only those included in the Path variable.

Include the full path c:\myfolder\myscript.ps1 or .\myscript.ps1

the other alternative is to add you folder to the path variable.

Auto load PowerShell Window in Server Core

When working with a server core I like to have a PowerShell window open. Here is a quick way to do it.

You could just type PowerShell in the cmd window to turn it into a PowerShell window or type Start PowerShell to open a separate PowerShell window.

To have it there waiting for you:

1. From cmd prompt run Regedit
2. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
3. Add string Value called PowerShell with value cmd.exe /k %windir%\system32\WindowsPowerShell\v1.0\powershell.exe.

Alternatively use the PowerShell Command

New-ItemProperty -path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\run -Name PowerShell -Value C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -Type string

Add a static IP route

TechNet: Add a static IP route

route adddestinationmasksubnetmaskgatewaymetriccostmetricifinterface

example #1: route add 10.0.0.0 mask 255.0.0.0  192.168.1.1

by adding this to a workstation you are saying they the route to the 10.0.0.0 network is via gateway 192.168.1.1. This assumes the workstation is on network 192.168.1.0.

This command would result in a temporary route to make it persistent add –p to the command.

example #2: route add 10.0.0.0 mask 255.0.0.0  192.168.1.1 –p

Rename folder/directory from command line

Rename folder\directory from command line using powershell

rename-item –path ‘c:\oldfoldername’ –newname ‘newfoldername’

“I was working with Hyper-V 2012 R2 free deployment in workgroup configuration and found that I had to change user to the built-in administrator account rather than a created administrator account to successfully run this command.”
