Re: reconfiguring RAM and CPU of VM machines

Try something like this

Import-Csvc:\vms.csv-UseCulture|%{    $vm=Get-VM-Name$_.VMName
    Shutdown-VMGuest-VM$vm-Confirm:$false
    while($vm.PowerState-ne"PoweredOff"){        sleep5
        $vm=Get-VM-Name$_.VMName
    }    Set-VM-VM$vm-MemoryGB$_.MemoryGB-NumCpu$_.NumCpu
    Start-VM-VM$vm-Confirm:$false
}

The CSV looks like this

"VMName","MemoryGB","NumCpu"

"VM1","8","2"

"VM2","4","1"

This script will do the stop-changes-start sequence 1 VM at a time.

You can do this in parallel, but that will require the script to keep track of each of the background tasks before starting the next step

Note: the script assumes that the VMware Tools are installed on the VMs.
