I assume you are looking for VMs that have a ParaVirtualSCSIController ?
If yes, you could do something like this
Get-VM|
SelectName,
@{N="PV";E={($_.ExtensionData.Config.Hardware.Device| where {$_.GetType().Name-eq"ParaVirtualSCSIController"}) -ne$null}}
If you also want to report on the paravirtualized NIC, you can do
Get-VM |
SelectName,
@{N="PVController";E={($_.ExtensionData.Config.Hardware.Device| where {$_.GetType().Name-eq"ParaVirtualSCSIController"}) -ne$null}},
@{N="PVNic";E={($_.ExtensionData.Config.Hardware.Device| where {$_.GetType().Name-eq"VMXNET3"}) -ne$null}}
