First I'd have recommend factoring above out in a helper, as it's repeated very similarly below another two times.

my sub check_max_length {
    my ($raw, $max_length, $warning) = @_;
    log_warn($warning) if defined($raw) && length($raw) > $max_length; 
}

check_max_length($conf->{description}, 64 * 1024, "description in config of node $node is too long! maximum will be 64k");


but I felt that joining all guests and all nodes each into a single warn was nicer, so I
reworked it a bit to first push all to an array and then output them joined, not the
nicest code but slightly shorter and the output looks good, IMO at least..
