numansarslanq, hi08:09
*** mickeys has quit IRC08:11
numansarslanq, OVN supports native l3. you can enable it by defining ovn_l3_mode=True in ml2_conf.ini.08:11
numansarslanq, although the  migration cook book should have done it. please verify what is the value there08:12
numansyou don't need to have l3 agent (although it would work, but you will not be using the ovn's l3)08:12

arslanqnumans: yes i missed a couple of params from ml2 config which i found on official guide. Now i can use OVN native l3 as well as DHCP service10:34
numansarslanq, thats great10:34
arslanqnumans: Thanks a lot for being here all the time  :)10:35
numans:)10:35
arslanqnumans: this is sbctl show output.....https://pastebin.mozilla.org/897912210:48
arslanqis this fine? since i have a couple of networks created and i can see them in nb database10:49

openstackgerritDong Jun proposed openstack/networking-ovn master: Support distributed NAT in networking-ovn native L3 routing  https://review.openstack.org/42413712:02
arslanqnumans: external connectivity is not working...12:36
arslanqmy configuration seems to be ok but its not working12:36
numansarslanq, do you see patch ports created between br-int and br-ex  ?12:37
numansarslanq, what version of networking-ovn code you are using ?12:38
arslanqpython-networking-ovn.noarch     1.0.0-1.el712:39
arslanqbr-int is in down state on both computes12:40
numansarslanq, you are able to ping 2 vms scheduled on 2 compute nodes right ?12:43
numansarslanq, for networking-ovn, i would suggest you to use the latest code and then patch this review - https://review.openstack.org/#/c/424137/ if its possible for you to test12:45
arslanqyes i am able to ping 2 VMs on different networks as well as on different computes12:45
numansarslanq, even otherwise it  should work.12:46
numansbut this patch simplies lot of things.12:46
arslanqnumans: ok i'll update networking ovn. could you please take a look on this and confirm https://pastebin.mozilla.org/897913612:47
numansarslanq, first verify if you have br-ex created and then there is a patch port between br-int and br-ex12:50
arslanqnumans: yes i have created br-ex i can see it....i am not sure about patch port thing12:50
numansarslanq, when you do ovs-vsctl show you should see a port in each bridge of type patch12:51
arslanqnumans: https://pastebin.mozilla.org/897913712:54
numansarslanq, i dont see any in this, how about another compute node ?12:55
arslanqnumans: i dont see here too https://pastebin.mozilla.org/897913812:56
arslanqon the other side after installing networking-ovn from the patch you sent...DB does not sync12:58

arslanqnumans: when i install networking-ovn on master...it gives me this error on upgrading DB https://pastebin.mozilla.org/897913913:11
russellbarslanq: how did you install?  it looks like neutron-lib might need to be upgraded13:12
russellbi see that module in the latest neutron-lib code13:13
arslanqi got the RPM from following link https://trunk.rdoproject.org/centos7-master/current/python-networking-ovn-2.0.0-0.20170206171102.fd62949.el7.centos.noarch.rpm13:14
russellbarmax: OK - i'd look for the latest neutron-lib as well13:15
russellbarslanq: what versions of everything else are you using?  master?13:15
russellbyou should probably be trying to use master of everything if you use master of networking-ovn13:15
russellbotherwise stuff like this will come up13:15
arslanqmakes sense....i am on newton branch of openstack13:16
numansrussellb, hi. arslanq used your ansible cookbook to upgrade to ovn :)13:23
russellboh, neat :)13:23
numanseverything is working for me except the external connectivity13:24
numansarslanq, did you try east west routing ?13:24
arslanqyes i have tried east west routing...it works...even on different networks13:25
*** lrichard has quit IRC13:27
*** salv-orlando has quit IRC13:29
arslanqrouter's interface of public network got "192.168.200.188"...vm cannot ping even this IP13:30
*** lrichard has joined #openstack-neutron-ovn13:30
*** kevinbenton has quit IRC13:32
numansarslanq, ok.13:32
russellbi think that might be an OVN bug13:32
russellbnumans and I saw that in testing not long ago ... (couldnt' ping OVN router's IP)13:33
russellbbut it works if you disable security groups, or at least add a rule allowing ingress ICMP13:33
numansrussellb, he has latest OVS code. suggested him to take to latest networking-ovn code and the patch - https://review.openstack.org/#/c/424137/13:34
russellbcool13:34
numansarslanq, if you want to stick with the old code - have a look at this blog - http://blog.spinhirne.com/2016/09/the-ovn-gateway-router.html13:35
numansthis could be helpful13:35
*** kevinbenton has joined #openstack-neutron-ovn13:35
numansarslanq, make sure that networking-ovn has scheduled the gateway router to some chassis. you can see that in the northbound db13:35
*** yamamoto has quit IRC13:39
arslanqnumans: yes i can see gateway router interface IP in northound13:41
*** yamamoto has joined #openstack-neutron-ovn13:41
numansarslanq, the patch port between br-int and br-ex should be created on the chassis where the gateway router is scheduled13:42
arslanqnumans: but i don't see such patch port created on either compute node as i sent you output of both13:43
*** yamamoto has quit IRC13:47
numansarslanq, what does the output of "ovn-nbctl list logical_switch" , "ovn-nbctl list logical_switch_port", "ovn-nbctl list logical_router" and "ovn-nbctl list logical_router_port" and "ovn-sbctl list port_binding" say ?13:47

arslanqnumans: any update? i am trying things on my end but nothing is working14:51
*** pcaruana has joined #openstack-neutron-ovn14:55
arslanqnumans: i dont even see packets hitting the br-ex or eth115:02
numansarslanq, that's because there is no patch port15:02
numansconnecting br-int and br-e15:02
arslanqnumans: can i do it manually for now?15:03
numansarslanq, sure15:03
*** mlavalle has joined #openstack-neutron-ovn15:04
numansarslanq, you mean creating a patch port ?15:04
numansarslanq, that is something which ovn-controller has to do.15:05
numansarslanq, something is wrong in your case. not sure why15:05
arslanqnumans: yes i was thinking so.......but why ovn-controller is missing this....i created public multiple times15:06
numansarslanq, you could use ovn-nbctl and try creating as per this blog - http://blog.spinhirne.com/2016/09/the-ovn-gateway-router.html15:06
numansand see if it works or not.15:06
numansarslanq, if it works, then something is wrong with networking-ovn15:07
arslanqwait, i put ovn_l3_admin_net_cidr = 169.254.128.0/30 in ml2_config.ini15:07
arslanqdoes this make any difference?15:07
numansarslanq, its required15:10
numansarslanq, unless you take the latest ovn and the patch i pointed out15:10
numansarslanq, may be that's the issue15:10
*** salv-orlando has quit IRC15:11
arslanqnumans: i tried to use the latest one but it gives some errors, since i am on newton branch it asks for neutron lib to upgrade at master to use networking-ovn master15:11
numansok15:11
*** salv-orlando has joined #openstack-neutron-ovn15:11
arslanqnumans: could you please take a look on this and confirm that this is ok https://pastebin.mozilla.org/897913615:16
arslanqnumans: on the other side i have a devstack setup with ovn and it has the following: https://pastebin.mozilla.org/897914915:35
numansarslanq, this looks good15:35
arslanqi am trying to add patch port but it does not allow me.....15:36
arslanqovs-vsctl add-port br-int br-ex15:36
arslanqovs-vsctl: cannot create a port named br-ex because a bridge named br-ex already exists15:36
arslanqnumans: these are ovs-vswitchd logs https://pastebin.mozilla.org/897915015:42
numansarslanq, did you attach your router to the public network ?15:42
numansarslanq, neutron router-gatewat-set <ROUTER> <PUBLIC_NETWORK_ID>15:43
arslanqnumans: yes i did set gateway  of router to that public network15:43
arslanqas i mentioned earlier that VM even cannot ping router gateway IP15:44
numansarslanq, as i said earlier you can follow the blog which i tried you and try to see if you can have the setup of gateway router manually using ovn-nbctl commands15:45
arslanqi have everything on my setup except patch port between bridges15:46
arslanqi am trying to create it15:46

*** salv-orlando has quit IRC15:54
numansarslanq, its not just about patch ports. looks like the transit gateway network is also not created.16:00
numanswhen you run "neutron net-list" you should see one extra network created by networking-ovn16:01
numanssomething is wrong.16:01
numanstry comparing with your devstack setup and this one16:01
arslanqnumans: this network should be created?  169.254.128.0/3016:02
numansyes16:02
arslanqthen this network is not created16:05
arslanqnumans: you are right this should be created https://pastebin.mozilla.org/897915616:08
arslanqnumans: when this network is supposed to be created ?16:14
numansarslanq, when you attach the gateway to the neutron router16:14
