A quick Hyper-V PowerShell one-liner today. This one will gracefully stop all virtual machines with RODC in their name.

 Get-VM -Name *rodc* | Where-Object {$_.State -eq "Running" } | Foreach-Object { Stop-VM $_.Name }

I needed this because I was cloning an RODC that I had virtualized, and I wanted a quick way to shut it down gracefully without actually logging on to it. (It's on a private subnet that is a nuisance for some things.) Then I simply extended it a bit to get all my RODC's and to make sure that I didn't try to stop a VM that was already stopped.

And, because I'm lazy and don't want to bother logging in to my VM host server, I modified this to get all the running VMs on the server and then stop them.

Get-VM -ComputerName Trey-VMHost `

          | Where-Object {$_.State -eq "Running" } `

          | Foreach-Object { Stop-VM $_.Name -ComputerName $_.ComputerName }

Notice that by the time I get to the end of the pipeline, I need to tell Stop-VM what computer these are running on. No problem, that's part of the object I'm passing in to it anyway. And, you could easily extend this by providing an array of host names to Get-VM to stop multiple VMs on multiple hosts.
