PowerCLI script to power off/on dedicated VMs listed in a .txt file + report power state

I had the requirement to shut down a large number of dedicated virtual machines listed in a .txt file and to turn them on again after a short time.

Additionally, I wanted to report the power state of these VMs after the scripted shutdown in a .csv file, to ensure that they were definitely powered off.

The following code snippets were used to complete this task:

Note: all code-snippets are processing the virtual machines listed in a text file „C:\temp\vmliste.txt“

Part 1 – Shutdown all VMs from the list „C:\temp\vmliste.txt“

 

foreach($vmlist in (Get-Content -Path C:\TEMP\vmliste.txt)){
$vm = Get-VM -Name $vmlist
Shutdown-VMGuest -VM $vm -Confirm:$false
}

Part 2 – Generate a .csv report with the powerstate of the listed VMs:

 

$powerstate = @()

foreach($vmlist in (Get-Content -Path C:\temp\vmliste.txt)){

$vm = Get-VM -Name $vmlist

$powerstate += (Get-VM $vm |

Select Name,PowerState,

@{N=’VMHost’;E={$_.VMHost.Name}})

}

$powerstate | Export-Csv -Path C:\temp\powerstate_report.csv -NoTypeInformation -UseCulture

Part 3 – Power on all VMs from the list „C:\temp\vmliste.txt“

 

foreach($vmlist in (Get-Content -Path C:\TEMP\vmliste.txt)){
$vm = Get-VM -Name $vmlist
Start-VM -VM $vm -Confirm:$false
}
