Should we rather not add those to the "local_resources" result in the
first place? I.e. in check_local_resources() we know whether it's a live
migration or not based on the $state argument.
And towards the end of that function we could...

...do "next if live-migration" and not even add it.
> push @loc_res, $k if $k =~ m/^(usb|hostpci|serial|parallel)\d+$/;
