ok did some digging and came up with this. pretty clean but works ....
get-cluster "xxxxx" | get-vm | Get-NetworkAdapter | Select-Object @{N="VM";E={$_.Parent.Name}},@{N="Network";E={$_.NetworkName}} | where {$_.Network -eq "dvPGName"}
Also not really understanding what $_.Parent.NAme is
please help me improve it
thanks
