I finally figure it out. My problem here is my physical switch connected to the interface used for VM sets up a VLAN range which mismatches the vlan range I used when installing openstack:
ML2_VLAN_RANGES=default:671:690
Another possibility is iptable rules that prohibit icmp request and you need delete them:
# iptables-save | grep icmp
......
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
