*** julim has joined #openstack-neutron12:39
amullerfrom my personal and very limited experience postgres seems to be less leniant than mysql, so if something you're working on isn't tested by Tempest then any postgres specific errors won't be caught... And the unit tests don't use postgres ofc, so you're left with manual testing12:39

jlibosvasalv-orlando: hi14:36
salv-orlandohi jlibosva14:36
jlibosvasalv-orlando: I'm comparing tables generated in havana by create_all with havana code base and tables created by havana_initial14:36
jlibosvasalv-orlando: there are some minor differences and I'm thinking if it is worth to make a one migration after havana that would fix that14:37
jlibosvasalv-orlando: for those upgrading from havana to juno (is it even supported?)14:38
salv-orlandowhy would we add a  migration after havana?14:38
salv-orlandoif it was not supported we would just start from icehouse14:38
jlibosvasalv-orlando: if someone started neutron server in havana without migration, the schema is different14:38
jlibosvasalv-orlando: ah, the healing will catch this...14:38
jlibosvasalv-orlando: nevermind, sorry for disturbing :)14:38
salv-orlandojlibosva: is that because the migrations up to havana are basically not in line with the models?14:39
jlibosvasalv-orlando: yes14:39
jlibosvasalv-orlando: more likely migrations from havana14:39
salv-orlandojlibosva: the only thing we need to check is that this will not cause other failures in the migration path14:39
salv-orlandoif that’s case then we won’t even get to healing14:39

jaypipeskevinbenton: with the Nova scheduler, there has been a push to separate out a large chunk of code into its own project17:06

jaypipeskevinbenton: and as a number of us have begun reviewing the blueprints and patches ostensibly trying to pull this out into its own component, we've realized that the extent to which the code is entangled within other pieces of the Nova codebase means that it's not something that can "live outside" the Nova tree (with or without any future intent of re-merging it into Nova) without major rework of internal interfaces that17:07

*** pballand has joined #openstack-neutron17:08

bjornarI dont feel I get enough debugging here to know the real cause..18:52
kevinbentonrkukura, jaypipes: my point is that there should have been a better way to coordinate such a major change to one component of the reference implementation18:53
rkukurabjornar: Run “neutron agent-list”, and make sure correct L2 agent is running on host cpu01.infrastructure18:53
rkukurakevinbenton: For some reason, I didn’t see any of this conversation prior to “kevinbenton: jaypipes: i see. but the DVR work was mostly just major changes to the reference L3 implementation”18:54

*** sbfox has joined #openstack-neutron18:57
kevinbentonrkukura: his point was that neutrons internal APIs suck and thats the root cause of use needing an incubator18:57
kevinbentonrkukura: i have an unrelated question. can the port API be used to mark a port as bound?18:58
kevinbentonrkukura: for Ironic or something similar to mark a created port as bound18:58
rkukurakevinbenton: I wouldn’t say the internal APIs suck, but there is certainly no preconception that they are intended to be stable18:58
rkukurakevinbenton: no18:59
kevinbentonrkukura: ok18:59
rkukurakevinbenton: I cannot see how ironic can possible use ML2 without implementing its own mechanism driver that knows what it means to bind a port to physical host’s physical NIC.18:59
kevinbentonrkukura: right, because something needs to put it on the appropriate segment…19:00
*** songole has joined #openstack-neutron19:00
bjornarrkukura, sure, all agents are running19:01
rkukurakevinbenton: That might involve a 2nd mechanism driver managing a ToR switch, as a hierarchical port binding19:01
kevinbentonrkukura: right, we chatted about this a bit19:01
kevinbentonrkukura: i had the extension for adding a switch port identifier19:02
*** amotoki_ has joined #openstack-neutron19:02
rkukurabjornar: Then, as admin, run “neutron agent-show <ID>” for the L2 agent on that host, and make sure the network’s physical_network shows up in that agent’s bridge_mappings (OVS) or interface_mappings (LB).19:02
*** amotoki has quit IRC19:03
rkukurakevinbenton: Not sure what you mean19:03
kevinbentonrkukura: ironic will need a way to inform neutron of the physical port location19:03

bjornarok19:06
kevinbentonjaypipes: so how would a better API have helped with the DVR work?19:07
rkukurakevinbenton: Seems to me that an ironic mechanism driver would be need to bind the port at the NIC level, basically by verifying that it can. Not sure if this would deal with flat network segments only, or with VLANs.19:07
bjornarrkukura, so should this be "integration_bridge" ?19:07

rkukurabjornar: That’s different - bridge_mappings isn’t used19:08

bjornarrkukura, it does19:09
kevinbentonrkukura: into an appropriate vlan/vxlan19:09
rkukurakevinbenton: That would require a mechanism driver, during port binding19:09
jaypipeskevinbenton: sorry, reading back, gime a sec :)19:09

*** snowgust has quit IRC19:13

bjornarI understand that the reason nova-compute gives me " Unexpected vif_type=binding_failed" is because neutron-openvswitch-agent returns that as port-type when it tries to create the port and fails..19:18
kevinbentonrkukura: lets say I want to attach a real router to an external network. right now there is no way to do that within neutron’s knowledge19:18
kevinbentonrkukura: i want to be able to express a physical port location to be provisioned onto the Neutron network19:19
rkukurakevinbenton: I’ve certainly used provider external networks, and their routers, directly.19:19
kevinbentonrkukura: and what did you have to do to put the router on the external network?19:19
bjornarwhat does "devices":0 mean here.. in agent-show19:19
rkukurakevinbenton: It was already their - I just set its gateway IP as the neutron subnet’s gateway IP19:20
*** mitarun has quit IRC19:21
kevinbentonrkukura: how did it get there on the right segmentation ID?19:21
jaypipeskevinbenton: k, done reading back... so, the question is not whether a better API would have helped with the DVR work. The question is whether better internal interfaces would have allowed the DVR work to exist entirely outside of the Neutron source tree.19:21
rkukurakevinbenton: It was a provider network that I created in neutron to match the existing network with the router19:21
openstackgerritSayaji Patil proposed a change to openstack/neutron: Implements sync mechanism between Neutron and Nuage VSD  https://review.openstack.org/11341819:21
rkukurakevinbenton: So are you asking how we’d attach this router to an arbitrary tenant network?19:21
kevinbentonjaypipes: it mostly can exist outside. i don’t think most of the cores want it to though19:22
kevinbentonrkukura: yes19:22
*** sambetts has quit IRC19:22
kevinbentonrkukura: or an external network that uses a regular segmentation ID19:22
*** aranjan has quit IRC19:22
kevinbentonrkukura: this is how we do our external networks so we don’t have to burn an interface on L3 agents19:22
kevinbentonrkukura: and right now to attach something, manual action is required on the backend controller to put the port in the right segment19:23
rkukurakevinbenton: In my case, the provider network was a specific VLAN on the same trunk with other VLANs being used for tenant networks19:23
kevinbentonrkukura: yeah, so vlan configuration on the router to match was necessary19:23
kevinbentonrkukura: i want to be able to make an access port basically whereever19:24
*** SayajiPatil has joined #openstack-neutron19:24
kevinbentonrkukura: so things like ironic or other arbitrary things that want access to a neutron network via a physical port can gain access19:24
bjornarjust to make sure, its just neutron-openvswitch-agent that should run on the compute node (along with nova-compute)19:25
jaypipeskevinbenton: correct me if I'm wrong, but the ML thread in question here was discussin jeblair's recommendations that the neutron-incubator be for code that should really exist separately from the Neutron source tree. And I was agreeing with him, and stating that there were some special unicorns (GBP and DVR for example) that were *proposed to go into the incubator*, but did *not* fit the "live forever outside of Neutron19:25
jaypipes" bill.19:25
rkukuraMy initial inclination would be to write a mechanism driver that does this.19:25
bjornar..and openvswitch itself ofcorse.19:25
rkukurabjornar: right19:26
kevinbentonrkukura: ok, but we need a new field in the port API to specify this19:26
jaypipeskevinbenton: I thought that is what we were discussing -- you had asked me what the special unicorns were and why they were special unicorns. And I answered that GBP and DVR were special because they really needed to be in the Neutron tree, and they needed to be in the Neutron tree because of the architecture of Neutron itself.19:27
rkukurakevinbenton: What exactly do you want to specify?19:27
kevinbentonrkukura: the switch port19:27
*** aranjan has joined #openstack-neutron19:27
kevinbentonjaypipes: DVR needs to be in the neutron tree because the cores have determined that it needs to be in the tree19:28
kevinbentonjaypipes: not because of API limitations19:28
rkukuraSo I’d like to undestand how this relates to specifying the host, which is necessary for current port binding19:28
kevinbentonrkukura: perhaps we just jam a switch port identifier in the host field?19:28
rkukurakevinbenton: In current port binding, host is what specifies “location”19:28
rkukuraThe port will never get bound without some value getting stored in host19:29
kevinbentonjaypipes: so i was pointing out that incubator was really for quickly iterating on things that want to be in core and not their own project19:29
bjornarrkukura, Any ideas then?19:29
*** pcm_ has quit IRC19:29
kevinbentonjaypipes: or things that are in core or require major changes19:29
kevinbentonrkukura: perhaps i should refactor my external attachment port work then to use the HOST_ID field19:30
*** pcm_ has joined #openstack-neutron19:30
kevinbentonrkukura: and then add a new mechanism driver19:30
kevinbentonjaypipes: *things that are in core but require major changes19:31

*** mitarun has joined #openstack-neutron20:17
rkukurakevinbenton: That could be used, for instance, if you wanted to let neutron decide which VLAN tag gets used.20:17
*** absubram_ has joined #openstack-neutron20:18
*** jorgem1 has joined #openstack-neutron20:18
kevinbentonrkukura: well in the ironic case, i don’t think they would have any vlan tags since these are baremetal servers that will end up running an arbitrary OS20:18
*** jorgem1 has quit IRC20:18
kevinbentonrkukura: they would most likely just want access ports so configuration of the gues OS is unnecessary20:19
rkukurakevinbenton: I’d imagine different VLANs might be used for things like control/management networks, tenant network tunnels, external networks, storage networks, …, portentially all on the same NIC (or bonded pair of NICs)20:19
*** jorgem has quit IRC20:20
kevinbentonrkukura: for ironic?20:21
*** mitarun has quit IRC20:21
rkukurakevinbenton: I’m thinking of OOO20:22
kevinbentonrkukura: oh, yes. that’s possible20:22
rkukurakevinbenton: Is ironic used for the undercloud in triple-O these days?20:23
kevinbentonrkukura: i think the host_id string would have to have a keyword to indicate that neutron should select the tag20:23
rkukurakevinbenton: makes sense20:23
*** Dafna has quit IRC20:23
kevinbentonrkukura: i’m not sure. i was just interested in it for the batemetal heavy workloads20:23
rkukuranot sure most switches can assign VLAN tags independently for each port20:23
rkukurakevinbenton: but I’m only familiar with tiny switches ;)20:24
kevinbentonrkukura: yeah, it depends on what the OS exposes. most of them have a VLAN translation table20:26
kevinbentonrkukura: but that keyword to let the MD select it should alleviate that issue20:27
rkukurakevinbenton: sounds good20:27

Sukhdevmarkmcclain: The flag that is set is VIR_DOMAIN_AFFECT_LIVE21:34
*** padkrish has joined #openstack-neutron21:35

Sukhdevmarkmcclain: In Minneapolis, when we tested VM migration, we had to upgrade the libvirt to 1.2.5 - you think something like that may be needed here to support this hotplug functionality?21:42

salv-orlandodhcp does not work.21:58
salv-orlandothey do not make sense21:58
kevinbentonwhy doesn’t it work?21:58
salv-orlandoI’ll add a trace to the bug report21:58
*** spandhe has joined #openstack-neutron21:58
salv-orlandoit’s dnsmasq - it won’t start.21:58
kevinbentonsounds like a dnsmasq problem :-)21:59
salv-orlandoso you’re suggesting I fix dnsmasq?21:59
kevinbentonthat might be hard21:59
kevinbentoni don’t like discriminating against /0 though22:00
salv-orlandowhat do you do with a /0 subnet?22:00
salv-orlandoand also since dnsmasq fails the dhcp agent keeps resyncing22:00
salv-orlandowith an issue like that I would be ok with discriminating against a /0 subnet22:01
salv-orlandoyou can call me a racist if you want22:01
kevinbentonlarger subnets need love too :’(22:02
* mestery has patches merged upstream into dnsmasq, it's not hard just ... odd.22:02
kevinbentoni suspect you would do twice as much with a /0 as you would with a /122:03
*** fungi has joined #openstack-neutron22:03
kevinbentoncan you put a note in your patch that it’s because of dnsmasq and not because there is something funamentally incorrect with it?22:03
*** suresh12 has quit IRC22:04
salv-orlandokevinbenton: but that standard /0 subnets are the most useful at all. Pity their not a subnet.22:04
salv-orlandokevinbenton: there is also a little problem that the default route and local scope are identical22:05
kevinbentonsalv-orlando: well there wouldn’t exactly be a default route, since the subnet contains everything :-)22:05
fungi(unless you consider a subnet to be like a subset in set theory, in which case the set s is technically also a proper subset of the set s)22:05
*** trad511 has joined #openstack-neutron22:05
salv-orlandokevinbenton: you’re going metaphisical!22:05
salv-orlandoI think there  might be an interesting parallel betwene subnetting and leibniz’s monad theory22:06
*** ijw_ has joined #openstack-neutron22:06
kevinbentonsalv-orlando: they are similar in that there are approximately the same number of people interested in them?22:07
* fungi wandered in late. i have context from the bug, but what is the current concern? just that there needs to be a more explicit comment added as to why /0 isn't allowed for a cidr in a neutron network?22:07
salv-orlandokevinbenton: that is a similarity22:07
kevinbentonfungi: yes22:07
salv-orlandoI think kevinbenton is merely saying that even if rarely used they’re conceptually correct22:08
salv-orlandoprobably the think fungi was saying about a set being considered a subset of itself.22:08
*** padkrish has quit IRC22:08
*** amcrn has quit IRC22:08
kevinbentonsalv-orlando: yeah22:08
fungiuser-facing comment, or code comment? i could get behind a code comment which says something like "we're disallowing /0 here because dnsmasq goes toes up, and also it's a silly choice of value"22:08
kevinbentonfungi: code comment22:08
kevinbentoni will now have to cancel my work of scaling to 4 billion VMs in a single network22:09
salv-orlandokevinbenton: and here you’re at fault as you’re not using ipv6 ;)22:09
fungianyway, from an operator/user perspective, i can't imagine actually balking when the ui tells me to go away because /0 isn't an allowed mask22:09
salv-orlandofungi: indeed I only found out it was possibly when I created it by mistake22:10
salv-orlandoI mean then if we keep allowing it we should disallow things like attaching to a router22:10
salv-orlandobecause that subnet would become a 2nd router gateway22:10
*** aranjan has quit IRC22:11
*** ijw_ has quit IRC22:11
salv-orlandoand then if they’re attached to a provider router shared by many tenants, that subnet could cause hell of a disruption I think22:11
