I will check openvswitch open-flow tables:
ovs-ofctl show br-int
......
1(int-br-eth4): addr:5a:cb:04:ab:33:90
config: 0
state: 0
current: 10GB-FD COPPER
speed: 10000 Mbps now, 0 Mbps max
2(tap130bc000-fb): addr:36:86:30:f5:bc:da
config: 0
state: 0
current: 10GB-FD COPPER
speed: 10000 Mbps now, 0 Mbps max
......
ovs-ofctl dump-flows br-int

Subject: Re: [Openstack] dhcp request can't reach br-int of network node
U can try few things quickly.
a) Connectivity between ur compute node and n/w node. Check the interfaces.
b) Check the route entry.
Ur compute node can ping to n/w node. U can also chk the vlan tag settings on
ovs bridge.

Hi guys,
My havana installation has 3 nodes:
control node, runs keystone APIs and neutron server;
network node, runs l3, dhcp, metadata, ovs agents; with VLAN mode
compute node, runs nova compute and ovs agents;
repo from
http://repos.fedorapeople.org/repos/openstack/openstack-havana<http://repos.fedorapeople.org/repos/openstack/openstack-havana/>,
and the os gets updated well with latest kernel.
Currently my VM can't get dhcp ack from network node.
Based the topology picture for the package flow:
http://docs.openstack.org/admin-guide-cloud/content/figures/10/a/common/figures/under-the-hood-scenario-1-ovs-network.png
With the tcpdump result on both network and compute node, it says the dhcp
request successfully leaves compute node, and it can reach the "int-br-eth1" of
network node, but not the next step br "br-int", so the dnsmasq would not able
to ack. I think this is the problem why I can't get dhcp ipaddr.
# uname -r
2.6.32-358.123.2.openstack.el6.x86_64
# ip netns (should we say namespace works well?)
qdhcp-11f3adc1-6a2e-429b-9679-b565347e2f74

qrouter-76c9b884-5928-42f4-a016-afab1b72066b
Anyone can help where/which section I should check for the issue next? or let
me know if other info is needed.
Thanks a lot.
Chris
