| russellb | arslanq: yes | 12:01 |
| arslanq | russellb: does ovn (NEWTON) support DPDK? same for l3-gateway? | 12:16 |
| russellb | we did not have l3 gateway support merged in newton | 12:17 |
| russellb | https://docs.openstack.org/developer/networking-ovn/dpdk.html | 12:17 |
| russellb | configuring networking-ovn for dpdk is just 1 config option ^^^ | 12:17 |
| russellb | otherwise you just have to configure OVS on nodes with dpdk as usual (not ovn specific) | 12:18 |
| arslanq | russellb: l3 gateway is supported in ocata? in DPDK works only with l3-agent running both in newton and ocata right? | 12:18 |
| russellb | l3 gateway is supported in ocata. l3 agent works in newton, but i think we stopped testing it in ocata. i don't recommend using it at all. | 12:19 |
| arslanq | russellb: i want to try DPDK with networking ovn, i just have to install dpdk integrated packages on all nodes and set option vhost_dock_dir in ml2 configuration file...is this all needed ? | 12:21 |
| russellb | that's the idea | 12:21 |
| russellb | but note that certain features are not yet fully supported by the dpdk datapath in OVS | 12:22 |
| russellb | let me find a link ... | 12:22 |
| arslanq | russellb: by above message you mean that DPDK should work in ocata without l3-agent running | 12:22 |
| russellb | yes | 12:22 |
| numans | arslanq, https://github.com/openstack/networking-ovn/blob/stable/newton/networking_ovn/common/config.py#L64 | 12:22 |
| numans | arslanq, https://github.com/openstack/networking-ovn/blob/master/networking_ovn/common/config.py | 12:22 |
| numans | there is a difference in the way newton version does and the master | 12:23 |
| numans | arslanq, i think for newton you have to vif_type in ml2_conf.ini, which is not required in the case of ocata/master | 12:23 |
| numans | *define | 12:23 |
| russellb | http://docs.openvswitch.org/en/latest/faq/releases/ | 12:23 |
| russellb | "Are all features supported in all datapaths?" | 12:24 |
| russellb | see "Userspace" column | 12:24 |
| russellb | most notably, NAT | 12:24 |
| russellb | (is not supported yet) | 12:24 |
| russellb | connection tracking is partially supported, AFAIK it just does not support IP fragmentation | 12:25 |
| russellb | so OVN ACLs (security groups) should work | 12:25 |
| arslanq | numans: russellb: i just want to test it if it works on basic note.....i think for now it should work what do you say? | 12:26 |
| numans | arslanq, i think it should :) | 12:26 |
| russellb | yes, and for the most basic test, i would suggest a provider network only | 12:26 |
| arslanq | russellb: yes are suggesting a provider network only because it does not support NAT right? | 12:27 |
| russellb | yes, and it's just the simplest network configuration | 12:28 |
| russellb | so a good place to start trying it out | 12:28 |
| arslanq | makes sense | 12:29 |
| arslanq | one question please.......as you mentioned above that i would just have to put one configuration option to use DPDK.....so i would not have to apply all these configurations in the link https://github.com/jrfastab/OVS/blob/master/INSTALL.DPDK.md | 12:30 |
| arslanq | numans: what service_plugins are supported for ovn? | 12:35 |
| arslanq | numans: i have just tried these two plugins qos,neutron.services.l3_router.l3_router_plugin.L3RouterPlugin | 12:38 |
| russellb | all of them! | 12:42 |
| russellb | (i don't know) | 12:42 |
| russellb | :) | 12:42 |
| russellb | qos is supported, not sure about the rest | 12:43 |
| arslanq | russellb: is there anyone who has actually tested DPDK with ovn, so i could take guidelines from him ? i'll be obliged | 12:57 |
| russellb | well ... yes | 12:58 |
| russellb | the person who worked on the networking-ovn code doesn't work on OVN anymore | 12:58 |
| russellb | the next person i would talk to is sean mooney from intel | 12:58 |
| russellb | who isn't in this channel, but is usually in #openstack-neutron at least | 12:58 |
| arslanq | russellb: ok let me find him and ask him if he can help me...thanks | 13:04 |
