HI All, DHCP requests from instances with interfaces on OVS/GRE based tenant networks are showing up on the tap device on the compute node but never make it to the physical network device (tcpdump -i ehtX proto gre).
If I manually configure an address all seems well & I can for example ping from the qdhcp namespace on the network note to the instance. This suggests to me that all the OVS plumbing is properly in place. My next suspicion is iptables, which look OK to me as well, or at least look like they do for the VLAN based provider networks that have functioning DHCP (note 10.0.1.100 is the dhcp-agent's address on this network): Chain neutron-openvswi-o78facbbc-b (2 references) target prot opt source destination RETURN udp -- anywhere anywhere udp spt:bootpc dpt:bootps neutron-openvswi-s78facbbc-b all -- anywhere anywhere DROP udp -- anywhere anywhere udp spt:bootps dpt:bootpc DROP all -- anywhere anywhere state INVALID RETURN all -- anywhere anywhere state RELATED,ESTABLISHED RETURN all -- anywhere anywhere neutron-openvswi-sg-fallback all -- anywhere anywhere root@nova-50:~# iptables -L neutron-openvswi-i78facbbc-b Chain neutron-openvswi-i78facbbc-b (1 references) target prot opt source destination DROP all -- anywhere anywhere state INVALID RETURN all -- anywhere anywhere state RELATED,ESTABLISHED RETURN udp -- anywhere anywhere udp multiport dports 1:65535 RETURN tcp -- anywhere anywhere tcp multiport dports tcpmux:65535 RETURN tcp -- anywhere anywhere tcp dpt:ssh RETURN icmp -- anywhere anywhere RETURN udp -- 10.0.1.100 anywhere udp spt:bootps dpt:bootpc neutron-openvswi-sg-fallback all -- anywhere anywhere Anyone see what I'm missing or have a suggestion on where I should look next? _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : [email protected] Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
