just figured out the problem !
following the icehouse installation guide for Ubuntu , page 55 .
the guide is like:
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
use_namespaces = True
what I put in is :
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriveruse_namespaces = True
after modify this part , all is working , and VM can traceroute to internet .
thanks !

Which version of OpenStack? If the router is plugged into br-ex and not br-int you may see this condition. Often, an external bridge like br-ex is not properly configured, leading to issues. You might try creating a provider bridge using the ovs-vsctl tool, defining the mapping in the plugin configuration file, and using router-gateway-set to associate the router with that network.
It would help to see your 'ovs-vsctl show' output along with the plugin configuration file and a 'neutron net-show <netid>' of the external network.
