Sorry for the confusion, now on doing tcpdump on guest's eth0, I saw
that the guest receives host's ARP response (for it's 192.168.99.1),
but is NOT receiving the host's ARP requests ("who-has 192.168.99.128
tell 192.168.99.1").

This observation is still valid. Looks like I'm missing something
basic. Any pointers?
Thanks,
