numansrussellb, no they aren't required13:50

openstackgerritNuman Siddique proposed openstack/networking-ovn: DONT MERGE : FOR TESTING ONLY - Test ovs python from sources  https://review.openstack.org/28059115:01
russellbnumans: are you sure it's "netdev-dpdk" ?15:04
russellbINSTALL.DPDK.md suggests it's "netdev"15:04
numansrussellb, oops15:05
numansrussellb, thanks for pointing it out. i will update the patch.15:05
russellbnp :)15:05
numansrussellb, in this patch which you had submitted some time back - https://review.openstack.org/#/c/280881/1/specs/newton/approved/vif-vhost-user-ovs-fallback.rst15:06
russellbyeah, i kinda gave up on that route15:07
numansrussellb, in line 57, sean mooney has mentioned that "netdev" is not sufficient. do we need to do more ?15:07
*** banix has quit IRC15:07
russellbhmm15:07
russellbi don't know.15:07
numansor "netdev" is good enough for us to set vif type as vhostuser.15:07
russellbi'd suggest trying to understand how neutron is handling this today15:08
russellbotherwiseguy should be able to help understand the current support15:08
numansrussellb, sure. that makes sense.15:09
russellbsounds like there is another check needed ...15:09
numansyes and not sure if ovn-controller should be able to do or it should do ?15:10
otherwiseguyIf OVS.datapath_type=netdev, and the compute host supports DPDK, DPDK will be used. (vhostuser will be passed as binding_profile and nova will do its thing).15:10
otherwiseguycan't run both dpdk/non-dpdk on same compute host basically.15:10
russellbso maybe we should add one more thing ovn-controller reports as an external-id15:10
russellbthe value of iface_types from the Open_vSwitch table in the Open_vSwitch database15:11
numansotherwiseguy, ok. netdev could mean any datapath other than system right ?15:11
numansrussellb, ok.15:12
russellbso then networking-ovn's check becomes --> ensuring datapath_type == netdev *and* that iface_types includes "dpdkvhostuser"15:12
*** armax has joined #openstack-neutron-ovn15:12
otherwiseguynumans: specifically it just means datapath_type=netdev. Other things could use the userspace datpath type, but neutron will pass vhostuser to nova only if dpdk supported and netdev configured. It's not what I would call ideal.15:12
russellbi mainly want to stay in sync with current behavior here15:13
russellbthe less surprises / minor differences, the better15:13
russellbdpdk is hard enough, heh15:13
numansotherwiseguy, ok.15:13
numans:)15:13
russellbnumans: that all make sense?15:14
numansrussellb, yes.15:14
russellbok15:14
numansotherwiseguy, l2 agent reports to neutron that dpdk is supported and netdev configured ?15:15

russellbwhat is "ew" heh15:23
Sam-I-Ameast-west15:23
russellbohhh ok15:23
russellbi read it as "ewwww"15:23
russellblike it was gross :-p15:23

russellbit's fine15:23
Sam-I-Amnow they're scenario-flowewwwww1.png :)15:24
russellbreally nice diagrams!15:24
russellbha15:24
russellbon #1, i thought it was more like #215:24
russellbguess i should check again15:25
Sam-I-Ami could be wrong. probably am.15:25
russellbi'm checking15:25
Sam-I-Amprovider networks dont use tunnels at least15:26
russellbright15:26
russellbi mean in terms of whether it skips the egress pipeline on the source node15:27
russellband then skips the ingress pipeline on the 2nd node15:27
Sam-I-Amyeah15:27
numansrussellb, neutron is doing the samething which you suggested to check above.  https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/openvswitch/mech_driver/mech_openvswitch.py#L8015:27
otherwiseguynumans: yeah, the agent sends back dictionary of agent_state with configuration containing ovs_capabilities, datapath_type, and vhost_socket_dir.15:27
russellbnumans: cool :)15:28
numansso its consistent.15:28
numansotherwiseguy, thanks for the confirmation.15:28
russellbSam-I-Am: your diagram is right :)15:30
russellbSam-I-Am: nice work on them15:30
Sam-I-Amyay!15:30
Sam-I-Amonce nat merges, or even routing between provider and self-service nets in general, there will be more15:31
Sam-I-Amand also native dhcp might need some love15:31
