Because when I disable dnsmasq from NetworkManager config, and I get the my regular DNS server into resolv.conf (of my host), the Virtualbox guests behave normal.
so I thought if the issue occurs with dnsmasq, and doesn't occur without it, then it's dnsmasq's fault and not Virtualbox (which can't really know if dnsmasq is even used or not).
