It's not inherited, $self is an "anonymous hash"
Observe:
root:~$ perl -Mstrict -le 'my $self={a=>"b"};print scalar(@{$self->{cpus}}) '
Can't use an undefined value as an ARRAY reference at -e line 1.
root:~$ perl -Mstrict -le 'my $self={a=>"b"};print scalar(@{$self->{cpus} ||
[]}) '
0
So adding these " || []" will avoid the error ([] means anonymous array aka
list)
root:~$ perl -Mstrict -le 'my $self={a=>"b",cpus=>["a","b","c"]};print
scalar(@{$self->{cpus} || []}) '
3

I can't answer this question right now, sorry, need some deeper investigation
which I can't
right now but can try later.

Add this line before the troublesome line:
return 1 unless $self->{cpus};
