Then I'd guess that most VMs end up with default '-numa node,mem' which by design can produce only fake NUMA without ability to manage guest RAM on host side. So such VMs aren't getting performance benefits or worse run with performance regression (due to wrong sched/mm decisions as guest kernel assumes NUMA topology is valid one).
Specifying NUMA distances in libvirt XML makes it generate the modern cmd line.
