| JoeC | Hello! | 02:28 |
|---|---|---|
| JoeC | I have a general question about how midonet connect to neutron database? | 02:29 |
| yamamoto | hi | 02:33 |
| JoeC | I am aware that midonet uses cassandra and zookeeper for its database | 02:35 |
| JoeC | however, I don't see any configuration on the neutron database? | 02:36 |
| yamamoto | neutron connects to midonet api, not vice versa | 02:37 |
| yamamoto | the neutron plugin for midonet has a configuration for it. | 02:38 |
| JoeC | ah! I see. That's how it got synced to the neutron DB. Thanks! | 02:39 |
| yamamoto | https://docs.midonet.org/docs/latest-en/quick-start-guide/ubuntu-1604_newton/content/neutron_controller_node_installation.html | 02:39 |
| yamamoto | see "Configure the MidoNet plug-in" section | 02:40 |
| JoeC | I see. Also, I noticed that the RDO version of this doc is not consistent with this version. for 5.4 | 02:41 |
| yamamoto | i guess i haven't looked at "the RDO version of this doc". where is it? | 02:45 |
| JoeC | https://docs.midonet.org/docs/latest-en/quick-start-guide/rhel-7_newton-osp/content/_controller_node_2.html | 02:46 |
| yamamoto | ah i see. i thought it was somewhere around https://www.rdoproject.org/networking/midonet-integration/ | 02:49 |
| JoeC | That made me a little confused on what to put under core plugin and service plugin | 02:49 |
| yamamoto | which part is inconsistent? | 02:50 |
| JoeC | Oh, cuz I am building the system from scratch. that's why I am running into some problems. | 02:50 |
| JoeC | It is under 7.2.1. Set the OpenStack Networking Plug-in | 02:51 |
| JoeC | https://thepasteb.in/p/58hgEmBXLl2Iv | 02:51 |
| yamamoto | ah, i see. which version of the plugin are you using? there are "openstack upstream" version and "midokura" version. | 02:52 |
| yamamoto | _ext stuff was only in midokura version. | 02:52 |
| JoeC | Oh! That's why. I am currently running Newton on my machine. | 02:53 |
| JoeC | so that _ext was preset on some setting on the midokura version then. | 02:53 |
| yamamoto | well, actually https://docs.midonet.org/docs/latest-en/quick-start-guide/rhel-7_newton-osp/content/_controller_node_2.html seems broken. | 02:53 |
| yamamoto | pure newton openstack/networking-midonet plugin ("upstream" version) have, say, midonet_v2. | 02:55 |
| JoeC | oh.... that explains the result well. i will use the apt doc for comparison on my REHL for now. | 02:55 |
| yamamoto | "midokura" version provides another version (midonet_v2_ext) which provides some extra feature. | 02:55 |
| yamamoto | packages in https://builds.midonet.org/openstack-newton/ are "midokura" version | 02:56 |
| JoeC | I see. I guess I will need to tare up the newton i have then. | 02:58 |
| yamamoto | oh, wait | 02:58 |
| yamamoto | actually i was wrong. python-networking-midonet-ext package is "midokura" addition which provides "_ext" ones. | 02:59 |
| yamamoto | it needs to be installed in addition to the base/upstream one (python-networking-midonet) | 03:00 |
| yamamoto | builds.midonet.org provides both of packages. | 03:00 |
| yamamoto | "tare up"? i'm not sure what it mean. (just because i'm not a good english speaker) | 03:02 |
| JoeC | I see. So I just need to install the ext package along with the upstream neutron. | 03:02 |
| yamamoto | yes. or just the upstream version, if you don't care the extra features. | 03:02 |
| JoeC | It was my bad; I should not have used the informal English on this occasion. | 03:03 |
| JoeC | I would like to use the extra features, of course. | 03:03 |
| JoeC | I am currently trying to test out midonet; therefore, I want to know it inside out. | 03:04 |
| JoeC | Also, when I built it before, I ran into another issue on "not able to change the username with mn-conf" | 03:06 |
| JoeC | by "tare up", I meant to say "rebuild" | 03:07 |
| yamamoto | i haven't seen the issue. some keystone related configuration? | 03:08 |
| JoeC | yeah. | 03:09 |
| JoeC | It occurred when I tried to put in the information for the midonet API user name | 03:10 |
| yamamoto | you improved my vocab. thank you | 03:11 |
| JoeC | Oh! No problem! You are helping my knowledge about midonet. It's a nice exchange! | 03:12 |
| JoeC | Also, for configuring midonet, I realized that the only way is through mn-conf? | 03:14 |
| yamamoto | https://docs.midonet.org/docs/latest-en/quick-start-guide/rhel-7_newton-osp/content/_midonet_cluster_installation.html | 03:14 |
| yamamoto | Configure Keystone access | 03:14 |
| yamamoto | you mean it didn't work? | 03:14 |
| yamamoto | for many of configuration, yes, mn-conf is the only way. (unless you count directo zk manipulation) | 03:15 |
| JoeC | It works. However, I ran into an issue if you use "admin" as the username you cannot change the username after. | 03:16 |
| yamamoto | you restarted midonet-cluster? | 03:17 |
| JoeC | I think so. I can try that when I finish building this midonet later today. | 03:18 |
| yamamoto | by cannot change you mean midonet keeps using the old username? | 03:18 |
| JoeC | yeah. It keeps using the username "admin" | 03:19 |
| yamamoto | while "mn-conf dump" etc shows the new username? | 03:19 |
| JoeC | yeah | 03:19 |
| JoeC | I mean no. | 03:20 |
| JoeC | mn-conf dump shows the old username | 03:20 |
| JoeC | even if I use mn-conf to change it already | 03:20 |
| JoeC | the dump still shows the old username | 03:20 |
| yamamoto | sounds strange. you run set and dump on the same node? | 03:21 |
| yamamoto | it might or might not be related to template/host thing | 03:22 |
| yamamoto | https://docs.midonet.org/docs/latest/operations-guide/content/_mn_conf_man_page.html | 03:22 |
| yamamoto | see -t and -h options | 03:23 |
| JoeC | I have seen the doc as well. that's why I was familiar with the command | 03:23 |
| JoeC | I even used unset to unset the username variable | 03:24 |
| JoeC | but when I set the new username on that part, it still shows the old username when it registered. | 03:24 |
| JoeC | yeah it was strange for sure. | 03:24 |
| JoeC | But I will let you know if I still get the same error later today. | 03:25 |
| yamamoto | i can't think of anything which can cause the behaviour right now. | 03:25 |
| JoeC | Sorry I forgot to mention that my environment is openstack on All-in-One version. | 03:25 |
| yamamoto | https://github.com/openstack/networking-midonet/blob/master/devstack/midonet-pkg/configure_and_start_midonet.sh | 03:29 |
| yamamoto | this script is used for openstack CI. it's kinda minimum configuration for all-in-one. | 03:29 |
| JoeC | Ah! thanks!!! this is a great help! | 03:31 |

| JoeC | Neutron log shows cannot find controller | 06:06 |

| JoeC | Is it normal to see the port on a bridge from midonet-cli that is showing "plugged no" and "state up"? | 07:37 |
| yamamoto | iirc plugged no just means it isn't bound to physical port. | 07:50 |
| yamamoto | ie. it's normal | 07:50 |
| JoeC | Is there a picture in the document about how a packet is flowed from the dhcp server in a subnet to the router? | 07:54 |
| JoeC | That is great! Thanks for the reply! | 07:54 |
