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 !
