Using PowerCLI, you can easily retrieve the status of CPU/Memory hot-add/remove. After logging in (use Connect-ViServer), run this cmdlet:

(Get-VM | Select ExtensionData).ExtensionData.config | FT -Auto Name, MemoryHotAddEnabled,CpuHotAddEnabled,CpuHotRemoveEnabled

If you only want a list of VMs which have hot-add/remove enabled for either CPU or memory, you can use filters to filter on this:

(Get-VM | Select ExtensionData).ExtensionData.config | ? {$_.MemoryHotAddEnabled -eq $true -or $_.CpuHotAddEnabled -eq $true -or $_.CpuHotRemoveEnabled -eq $true} | Select Name, MemoryHotAddEnabled,CpuHotAddEnabled,CpuHotRemoveEnabled | FT -Auto

To export the result to CSV, replace the FT -Auto in the cmdlet above with Export-Csv "path\to\file.csv"
