Paras, And do you see GRE tunnels at all in your ovs-vsctl show output?

Can you pls provide me with some info about those speed marks? Like, if it`s on 0 - that means that no tunnels are working properly?

Empty output from "ip netns" can be either not using namespaces (run grep "use_namespaces /etc/neutron/l3_agent.ini" to find out) or using wrong iproute package. Could you please also check what does tcpdump report? could you see the discover on the dhcp nic (when using ovs it's a tapxxxxxxxx-xx nic)? could you see an offer sent from that nic? -Paras.

I would start with: * ps -efl | grep dnsmasq | grep -v grep - to verify that the dnsmasq process is running, you can also check the conf file appeas in this output * ip netns - to get the list of namespaces * ip netns exec <the_right_dhcp_namespace_name> tcpdump -i any ... - to look for the dhcp offer or arp issues * ping each other - instance to dhcp address, and vice versa (the second one should be done from within the namespace) Thanks _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack -- Thanks, Rami Vaknin, QE @ Red Hat, TLV, IL. -- Thanks, Rami Vaknin, QE @ Red Hat, TLV, IL. _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack -- http://igordcard.blogspot.com -- http://igordcard.blogspot.com _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
