Hi, just made a fresh installation of the Liberty release on Ubuntu 14.04 and I am running into some network problem that I dont understand them. I think the biggest problem is: Failed to bind port 802862a2-223f-4e32-bc9c-b5821351f70b on host hv02

What is interesting that no bridge device is getting created on the controller node.

bertly ( 2016-06-02 02:32:09 -0600 )edit

check neutron agent-show $UUID-of-lbagent , and the linuxbrige agent logs. Is the network vxlan or vlan or flat?

darragh-oreilly ( 2016-06-02 05:13:42 -0600 )edit

Hi darragh-oreilly,

agent list: http://paste.openstack.org/show/507263/ linuxbridge message: http://paste.openstack.org/show/507264/

The network type is flat.

bertly ( 2016-06-02 06:55:51 -0600 )edit

any idea why flat network is not working? I cant see the error.

bertly ( 2016-06-13 02:55:50 -0600 )edit

try deleting the flat net and recreating it - this should get rid of the ports with binding failed

Apparently this is the source of the problem:

2016-06-02 10:52:19.891 25325 WARNING neutron.plugins.ml2.rpc [req-8c475288-1845-4833-ad95-253a0f66a8ea - - - - -] Device tapb965d58e-39 requested by agent lb005056bf2186 on network xyz not bound, vif_type: binding_failed

Any idea why is not creating the device? I dont use ovs.

UPDATE:

When I use a vxlan network the bridge devices gets created and the vm gets a ip from the dhcp server, but cant get any network connectivity.

brctl show

bridge name bridge id       STP enabled interfaces
brq71cd4b3b-61      8000.fe163e5dc9de   no      tap3a1c88a2-06
                            vxlan-101
virbr0      8000.52540064d0ef   yes     virbr0-nic

But it did not add the actually device to the bridge (eth0.101) When I add the device "brctl addif brq71cd4b3b-61 eth0.101" the network is working as expected. Not sure if this should be like this.

Should the actually device not automatically added to the bridge?

for a network of type vxlan, it is not supposed to add a physical or vlan interface to it

darragh-oreilly ( 2016-06-02 08:52:55 -0600 )edit

so its intended that I add it manually or should it work without that? Not sure if i got vxlan the right way.

bertly ( 2016-06-02 09:03:13 -0600 )edit

no. You should create a neutron router, and connect it (using the API) to the internal net. And uplink (neutron router-gateway-set) it to an external vlan or flat net. The router does NAT.
