@Dan :

I change to VLAN 7 but same :

root@compute1:~# tcpdump -n -e -vv -ttt -i eth1 | grep "vlan 7" 00:00:00.254417 fa:16:3e:38:08:c8 > 33:33:00:00:00:02, ethertype 802.1Q (0x8100), length 74: vlan 7, p 0, ethertype IPv6, (hlim 255, next-header ICMPv6 (58) payload length: 16) fe80::f816:3eff:fe38:8c8 > ff02::2: [icmp6 sum ok] ICMP6, router solicitation, length 16

root@controller:~# tcpdump -n -e -vv -ttt -i eth1 | grep "vlan 7"

... nothing

@asktask :

No I didn't yet. I use 2 computes nodes and 1 controller. I want to stay in this configuration and to solve my issues with real hardware.

Here you can find Agent logs when I create a VM :

DEBUG:root:## running command: sudo ovs-vsctl --timeout=2 list-ports br-int DEBUG:root:## running command: sudo ovs-vsctl --timeout=2 get Interface eth1 external_ids DEBUG:root:## running command: sudo ovs-vsctl --timeout=2 get Interface eth1 ofport DEBUG:root:## running command: sudo ovs-vsctl --timeout=2 get Interface tap2d31bc15-08 external_ids DEBUG:root:## running command: sudo ovs-vsctl --timeout=2 get Interface tap2d31bc15-08 ofport DEBUG:root:## running command: sudo ovs-vsctl --timeout=2 set Port tap2d31bc15-08 tag=4095 DEBUG:root:## running command: sudo ovs-ofctl add-flow br-int priority=2,in_port=2,actions=drop

Someone knows if actions=drop is normal ?

After more investigations with Pedro Navarro Pérez,

We found why we have "actions=drop", it's because my computes nodes were not able to access to Database (my fault).

But my VMs does not have access yet to the network.

In ovs_quantum database, I can see the ports (my VM TAP and the Gateway). The port of my Gateway is state "ACTIVE" but in op_status "DOWN". Is it normal ?

What can I do ?

I try several times to delete / recreate networks, but always the same situation.

I continue investigations.

The port of my Gateway is state "ACTIVE" but in op_status "DOWN" because I did not run OVS Agent on controller (also nova-network).

So now, I run the agent on the controller, and my gateway is ACTIVE & UP.

If I read http://openvswitch.org/openstack/documentation (http://openvswitch.org/openstack/docu...) , it's written that the agent must be run from computes nodes, or maybe I did not understand :-).

My VMs does not have access yet to the network. Coming soon I hope !!

@Dan

As usual, thank's for support.

• For the doc, don't worry, I'm glad my work can be useful for everybody.

• I like DevStack but I want to build my architecture from scratch with the goal to be a Jedi in Quantum :-) (and OpenStack also). I always use DevStack as a reference when I need to confirm an information about configuring or something else. But in my case I can see everythink is like DevStack without Melange (Should I use it ?) and I did not launch "ovs-vsctl --no-wait br-set-external-id $OVS_BRIDGE bridge-id br-int" (-> Is it usefull ? Can you explain me why DevStack is using it ?)

• For debugging, of course I use Databases and tomorrow I will continue to post here the news about my work.

Thank's again Dan !

Dan,

• Today I've setup DevStack and I've compared all the stuffs : I've exactly the same configuration.

• When I dump the traffic I can see something strange :

  *tape3f5c3b2-c5 sends DHCP DISCOVER

  *All eth1 (connected to br-int) can see this DHCP packet

  *gw-385e6c3d-18 can't see the DHCO packet.

On my controller / nova-network / Quantum-Server :

Bridge br-int
    Port br-int
        Interface br-int
            type: internal
    Port "eth1"
        Interface "eth1"
    Port "gw-385e6c3d-18"
        tag: 1
        Interface "gw-385e6c3d-18"
            type: internal

On my compute node :

Bridge br-int
    Port br-int
        Interface br-int
            type: internal
    Port "eth1"
        Interface "eth1"
    Port "tape3f5c3b2-c5"
        tag: 1
        Interface "tape3f5c3b2-c5"

DNSMASQ is running on controller -> http://paste.openstack.org/show/18447/

And on the controller I can see my VM IP Configuration in /var/lib/nova/networks/nova-gw-385e6c3d-18.conf : fa:16:3e:72:48:2d,host-192.168.22.3.novalocal,192.168.22.3

In my ovs_quantum database, all the ports are ACTIVE / UP (gateway + TAP).

So... What's wrong ?

The nova.conf of my controller is it correct ? -> http://paste.openstack.org/show/18448/

Nova-compute.conf of my computes nodes : http://paste.openstack.org/show/18449/

Thank's
