| claudiub | cool. regarding the live-resize. do you really want to support live-downsize as well? | 09:32 |
| *** alexchadin has joined #openstack-nova | 09:32 | |
| claudiub | there's quite a bit of opposition to that. :) | 09:32 |
| claudiub | or maybe we can add support for upsizing first, and then look into downsizing afterwards | 09:34 |
| *** amoralej|off is now known as amoralej | 09:34 | |
| jichen | no, actually, I am ok if we only support upsize at first cycle | 09:34 |
| claudiub | the nova cores seems to be fine with upsizing.' | 09:34 |
| jichen | exactly, I agree with you | 09:35 |
| jichen | upsizing should be first priority | 09:35 |
| claudiub | great, then I will amend the spec to mention this fact. | 09:35 |
| jichen | ok, perfect, thank you~ | 09:35 |

| stephenfin | Does anyone else think reviewing specs in Gerrit is a PITA? How the heck did the docs team do it for so long? | 11:00 |
| Spaz-Work | I wish I knew more about specs | 11:02 |
| kashyap | stephenfin: What might be a better way? | 11:02 |
| stephenfin | kashyap: Something that lets you comment on the rendered spec would be a huge help | 11:03 |
| stephenfin | a la Google Docs | 11:03 |
| kashyap | stephenfin: Not that I'm advocating "for Gerrit" (with which I have a "can't live with you, but have to live without you" relation) | 11:03 |
| *** pchavva has joined #openstack-nova | 11:03 | |
| kashyap | stephenfin: What is it that is specifically bothering you? | 11:03 |
| *** yamamoto has quit IRC | 11:04 | |
| stephenfin | Take this spec, for example https://review.openstack.org/#/c/552722/ | 11:04 |
| * kashyap clicks | 11:04 | |
| stephenfin | artom has kindly gone through and linked to a load of places in the code in order to explain some of the things he's talking about | 11:04 |
| kashyap | The pig is still loading | 11:04 |
| kashyap | stephenfin: And | 11:05 |
| stephenfin | However, I can't click those links because it's just text. All the rst->html magic hasn't been applied yet | 11:05 |
| kashyap | (I saw that spec, meaning to review) | 11:05 |
| kashyap | Ah-ha | 11:05 |
| stephenfin | Similarly, for my NUMA aware vSwitch spec, I included a load of images but none of those render in the rST, naturally enough | 11:05 |
| kashyap | Hmm, nod | 11:06 |
| stephenfin | So you end up with this schizophrenic style review where you're having to review the HTML version then jump back to the rST version to leave comments | 11:06 |
| stephenfin | It's just...silly :) | 11:06 |
| stephenfin | Also, Realistically, no one should care about the formatting of the source for a doc. It's the output that matters | 11:06 |
| * kashyap goes to add a comment in the spec, before he forgets | 11:06 | |
| stephenfin | But yeah, </rant> :) | 11:07 |
| stephenfin | stupid Gerrit :mutter mutter: | 11:07 |
| kashyap | stephenfin: Yeah, I hear the pain, I just try to focus on the core content, and the formatting not to be egregious | 11:07 |
| stephenfin | kashyap: Do. It would be a good thing to finally resolve | 11:08 |
| kashyap | stephenfin: BTW, slightly related: Some people seem to think 'patchwork' is "dead" | 11:08 |
| *** sidx64 has quit IRC | 11:08 | |
| stephenfin | Oh, really? | 11:08 |
| kashyap | stephenfin: And QEMU folks have written their own: http://patchew.org/ | 11:08 |
| kashyap | There's a bit of overlap with 'patchwork' | 11:08 |
| kashyap | stephenfin: See this snippet: | 11:08 |
| kashyap | 17:59 < kashyap> bonzini: Isn't there some overlap between 'patchew' and 'patchwork'? | 11:08 |
| kashyap | 17:59 < bonzini> kashyap: yeah, but patchwork seemed dead when patchew was started | 11:08 |
| kashyap | From a week or so ago | 11:09 |
| kashyap | (On OFTC, #qemu) | 11:09 |
| stephenfin | Yup, that's been around for a while. At the time Patchwork _was_ dead | 11:09 |
| kashyap | Ah-ha, I see | 11:09 |
| stephenfin | Was only when I and another Intel dev started working on it (for freedesktop) that it started moving forward again | 11:09 |
| kashyap | Most people used 'patchwork' as just a "tracker" of patches, though | 11:10 |
| stephenfin | Guess the two could be folded in but meh, I've barely any time to work on Patchwork of late | 11:10 |
| Spaz-Work | Nova meeting is 2100 today right? | 11:11 |
| *** sidx64 has joined #openstack-nova | 11:11 | |
| * kashyap still loves the traditional patch workflow of QEMU / Kernel. Yes, the learning curve is steep, but by _Jove_ is it a joy! | 11:11 | |
| * kashyap stops complaining & crawls back into his cave | 11:12 | |

| lpetrut | mdbooth: Hi, thanks for letting us know. I took a look over the patch and it looks good, it shouldn't affect the Hyper-V driver. High chance is that we'd only have issues with the Dell iSCSI driver that you're mentioning in the commit (which should be fixed by it). | 13:02 |

| mdbooth | lpetrut: What changes is that I'm now passing the *old* bdms to post_live_migration instead of the new ones | 13:02 |
| mdbooth | So connection_info will relate to the source host, which is where it's actually running, rather than the destination | 13:03 |
| lpetrut | mdbooth: do you know by any chance if there are any other iSCSI drivers that would return different connection info among hosts (i.e. have a different conn info on the destination)? | 13:03 |
| mdbooth | lpetrut: Potentially a lot, I think | 13:03 |
| mdbooth | That particular issue has been around for ages | 13:03 |

| *** sidx64 has quit IRC | 13:52 | |
| kholkina | mriedem, the spec means to update user-data on booted instance, without rebuild. It may be useful to provide a cloud-config | 13:52 |
| efried | cdent: Even if it's '1.0'? | 13:54 |
| jaypipes | efried: yeah, agree with alex_xu_ it would be good to be consistent there. | 13:54 |

| cdent | no | 13:55 |
| cdent | It's, as jay says, no biggie, but if you're adding something new may as well make the version explicit, even if it is the base | 13:55 |

| dansmith | belmoreira: go for it | 14:08 |
| belmoreira | thanks dansmith | 14:08 |
| belmoreira | We use the same cloud to deploy VMs and baremetal. Baremetal is dedicated to few cells. | 14:09 |
| belmoreira | When consolidating the scheduler at top level (not per cell as in cellsV1) not seeing how can dedicate schedulers to ironic cells because they need the baremetal_filters enabled. | 14:09 |
| dansmith | belmoreira: the baremetal filters are deprecated | 14:09 |
| -openstackstatus- NOTICE: POST_FAILURE results on Tempest-based jobs since the most recent Zuul security fixes are being investigated; rechecking those won't help for now but we'll keep you posted once a solution is identified | 14:10 | |
| *** ChanServ changes topic to "POST_FAILURE results on Tempest-based jobs since the most recent Zuul security fixes are being investigated; rechecking those won't help for now but we'll keep you posted once a solution is identified" | 14:10 | |
| dansmith | belmoreira: the way of the light is custom resource classes for the ironic nodes, and flavors configured to give you the right thing when you ask, which makes scheduling uniform | 14:10 |
| belmoreira | I missed that | 14:11 |
| mriedem | there was a caveat with dropping the ironic host manager for the scheduler, would have to dig it back up, | 14:11 |
| mriedem | but i think it's that not all filter scheduler filters will be able to handle baremetal instances, numatopologyfilter specifically i think | 14:11 |
| belmoreira | I'm finding the release notes about this. thanks | 14:12 |
| mriedem | i'll be damned if i can find the way to those docs in ironic via their homepage | 14:12 |
| belmoreira | :) | 14:13 |
| mriedem | belmoreira: https://docs.openstack.org/ironic/latest/install/configure-nova-flavors.html#scheduling-based-on-resource-classes | 14:13 |

| mriedem | NUMATopologyFilter isn't enabled by default, but i know a lot of people use it | 14:16 |
| mriedem | if we had someone that was familiar enough with both nova and ironic (cough jroll johnthetubaguy mgoddard_ cough) we could have them play around with updating an ironic CI job to not use the ironic host manager and baremetal filters and see what breaks | 14:17 |
| mgoddard_ | mriedem can I offer you a throat sweet? | 14:18 |
| mriedem | wtf | 14:18 |
| mgoddard_ | for your cough | 14:18 |

| *** yamamoto has joined #openstack-nova | 14:20 | |
| dansmith | mriedem: that needs fixing if so | 14:20 |
| dansmith | maybe we could get stephenfin or someone to look at that once we know it's really a problem | 14:20 |
| stephenfin | I didn't do it | 14:21 |
| stephenfin | I've never used ironic so I'm probably not your guy | 14:22 |
| mriedem | apparently ironic has a CI job (or defalut?) to use resource classes so they don't use the ironic hos tmanager https://review.openstack.org/#/c/499106/ | 14:22 |
| mgoddard_ | yes, ironic devstack plugin uses resource classes by default | 14:23 |
| mriedem | good news, mogan does too http://codesearch.openstack.org/?q=IRONIC_USE_RESOURCE_CLASSES&i=nope&files=&repos= | 14:23 |
| dansmith | stephenfin: we need someone that understands the numa filter not necessarily ironic | 14:23 |
| stephenfin | Oh, that I can do | 14:23 |
| dansmith | mriedem: but no numafilter presumably | 14:23 |
| mriedem | nope, so i think i can just hack up devstack and say don't use the baremetal filters and add numatopologyfilter to the list of default enabled filters and see what blows up | 14:24 |

| dansmith | mriedem: the thing is I would expect cinder to maybe be able to do it more efficiently in some cases (i.e. ceph) | 15:20 |
| smcginnis | Especially as I'm not sure how that would work with a boot volume. We can't detach those normally, right. | 15:20 |
| *** moshele has quit IRC | 15:20 | |
| dansmith | smcginnis: we're talking about bfv here | 15:20 |
| dansmith | smcginnis: we're doing a rebuild, so we'd detach | 15:20 |
| smcginnis | dansmith: Yeah, so that would be an extra complication. | 15:20 |
| smcginnis | dansmith: Oh, right! | 15:20 |
| openstackgerrit | Mathieu Gagné proposed openstack/nova-specs master: Multiple Fixed-IPs support in network information https://review.openstack.org/312626 | 15:21 |
| mriedem | the volume would remain in-use during all of this from a state pov | 15:21 |
| smcginnis | So delete instance, detach volume, cinder rewrites it, reattach, create new "rebuilt" instance using it. | 15:21 |

| dansmith | mdbooth: if people are multi-attaching bfv then I give up | 15:22 |
| mriedem | we create a 2nd attachment to keep the volume 'in-use' and then delete the first attachment | 15:22 |

| mriedem | we have another issue with cleaning up stuff in placement mentioned here https://review.openstack.org/#/c/502306/17/specs/rocky/approved/bandwidth-resource-provider.rst@228 | 15:58 |
| cfriesen_ | mriedem: we've got a reported bug that deleting then re-adding a compute node with the same name results in not being able to schedule due to this placement issue | 15:59 |
| mriedem | if you disable a compute or it's down, and delete instances from it and then purge them from the db, the allocations for those instances against that compute are never removed from placement | 15:59 |
| cfriesen_ | ew | 16:00 |
| mriedem | cfriesen_: well, how did they delete the compute node record? directly in the DB? | 16:00 |
| mriedem | if you're monkeying with the db, then you are also going to need to deal with cleaning up placement as a result | 16:00 |
| mriedem | at least for now, until we have some interface for this | 16:00 |
| cfriesen_ | mriedem: I don't think they did delete the comptue node record, just the service | 16:00 |
| mriedem | then i don't see how the compute node uuid would change unless the hostname changed or something | 16:01 |

| mriedem | and placement entries for those compute nodes | 16:02 |
| *** alexchadin has quit IRC | 16:03 | |

| cfriesen | sahid_: I'm back. So on power_off() we _destroy() the instance (but leave it defined) and remove the serial ports from ALLOCATED_PORTS.

| jaypipes | artom: I don't think it's necessary to depend on bauzas' spec. I think that would endanger making progress on fixing live migration for NUMA/pinning | 16:54 |
| artom | jaypipes, right, so leave the NUMA RPs thing to itself, and just fix the pin mappings for now. I'd tend to agree, for what it's worth - feels like a more incremental step, and not a major overhaul | 16:56 |
| jaypipes | artom: ++ | 16:57 |
| cfriesen | sahid_: in the _hard_reboot() case we call destroy(), which does _destroy() and then cleanup(), and that will undefine the instance. Arguably that's the point where we should remove the TCP port from ALLOCATED_PORTS. Then we generate new xml with new TCP ports and all should be happy. | 16:57 |
| *** lpetrut has quit IRC | 16:57 | |
| jaypipes | artom: and all I was asking was that you make a little more explicit in the spec what is and what isn't "claimed". | 16:57 |
| cfriesen | sahid_: removing the TCP ports from ALLOCATED_PORTS while they're still defined in the domain is just asking for trouble. | 16:58 |
| artom | jaypipes, totally fair. | 16:58 |
| openstackgerrit | Merged openstack/nova stable/pike: doc: fix the link for the evacuate cli https://review.openstack.org/542856 | 16:58 |
| artom | jaypipes, err, you're using "claimed" because the compute node doesn't actually talk to placement to "claim" the pinned pCPUs, right? | 16:58 |
| sahid_ | cfriesen: if you can make all of that better i will be happy to review any of the your patches | 17:01 |
| jaypipes | artom: no, I'm saying that "claim resources" means something very specific in the scheduler -- it is the call to placement to PUT /allocations/{instance_uuid}. And that does *not* include any NUMA resources right now. So I want the spec to be clear about that. When you say "claim in the scheduler", that's not actually what happens. The "claim on the compute" is the old way of allocating resources from the compute node to the instance by writing | 17:01 |
| jaypipes | the record to the compute_nodes cell DB table. that is still done for NUMA and PCI resources in the resource tracker's instance_claim() method. | 17:01 |

| cfriesen | sahid_: cool, if I get some time I'll hold you to that. :) | 17:04 |
| cfriesen | jaypipes: artom: this spec only talks about CPU pinning, but we also need to recalculate the destination NUMA node for hugepage-backed instances even without CPU pinning. | 17:05 |

| *** ralonsoh__ has joined #openstack-nova | 17:06 | |

| jaypipes | dansmith: no, it's virtually instantaneous | 17:10 |
| dansmith | jaypipes: ack | 17:10 |
| dansmith | claudiub|2: so I think there should be at least one more exception in whatever test that is, so you can copy that for yours I think | 17:10 |
| artom | cfriesen, not a bad idea :) | 17:11 |
| jaypipes | honestly, we really shouldn't be using the ENUM type anyway... but meh | 17:11 |

| edleafe | efried: excellent recap | 18:55 |
| dansmith | mriedem: that's true, I guess a flavor or request with pci or numa could break if there are ironic hosts in there somehow, | 18:55 |

| mriedem | cfriesen: is there anything you guys don't have a private patch for? | 18:59 |
| cfriesen | mriedem: we try to upstream stuff, but it takes forever | 18:59 |
| mgoddard_ | mriedem: that's good news! | 18:59 |
| *** moshele has quit IRC | 18:59 | |
| cfriesen | mriedem: plus, we only need to worry about one hypervisor | 19:00 |
| mriedem | mgoddard_: well, it's kind of a false positive i think | 19:00 |
| mriedem | cfriesen: it takes even longer when you don't even propose them | 19:00 |
| dansmith | mriedem: it's not a false positive, it's just not comprehensive.. it means something, it just doesn't mean it all works fine :) | 19:00 |
| mriedem | i think host_topology_and_format_from_host might be the thing | 19:01 |
| mriedem | that's just always None for ironic i think | 19:02 |
| cfriesen | mriedem: yeah, I know. I don't control how much upstreaming time I get. Looks like we modified NUMATopologyFilter to check the hypervisor type, and modified AggregateInstanceExtraSpecsFilter to ignore the "baremetal" and "storage" keys. | 19:02 |
| dansmith | mriedem: if that breaks if it's none, that probably also precludes using any two hypervisors together where one is libvirt with numa and the other doesn't support it, right? | 19:02 |
| mriedem | nvm, that would just filter out that ironic node | 19:03 |

| mriedem | because at some point i thought these wouldn't work but i can't figure out why now | 19:04 |

| *** artom has quit IRC | 19:10 | |
| mgoddard_ | perhaps the bug is just that the NUMA filter doesn't work for ironic, rather than that it rejects all bare metal hosts? | 19:11 |
| cfriesen | sean-k-mooney: don't think so, this was specifically part of allowing one nova-scheduler to handle both libvirt/kvm and ironic compute nodes | 19:12 |
| sean-k-mooney | cfriesen: ah ok | 19:12 |
| *** esberglu_ has joined #openstack-nova | 19:12 | |
| sean-k-mooney | mgoddard_: well if i ask for a 2 numa node instance the ironic should be able to select a node with 2 numa nodes however i dont think ironic adds numa info into the compute nodes table for the filter to use | 19:13 |
| mgoddard_ | exactly | 19:13 |
| mgoddard_ | same with cpu pinning | 19:14 |
| sean-k-mooney | mgoddard_: no cpu pinning is different | 19:14 |
| mgoddard_ | and hyperthreading | 19:14 |
| cfriesen | mriedem: back to the nova-compute service delete issue, when deleting a service via the API, nova.db.sqlalchemy.api.service_destroy() will soft-delete both the service and the service and the compute_node entry, but placement is still around. Then we create the compute node again and get new service and compute_node entries with a different uuid but the same hostname. | 19:14 |
| sean-k-mooney | cpu pinning does not make sense in a phyical server context | 19:14 |
| dansmith | it wouldn't matter these days anyway, ironic nodes report a CUSTOM_IRONIC_FOO resource and no cpu/mem | 19:14 |
| *** esberglu has quit IRC | 19:14 | |
| mgoddard_ | sean-k-mooney: ok, you're right about pinning. hyperthreading could (but doesn't) work though | 19:15 |
| dansmith | cfriesen: mriedem because we store service_id in the compute node, so we won't find the existing one when we re-create the service | 19:15 |
| dansmith | cfriesen: mriedem I bet that api was never updated when we added the node concept.. it probably needs to delete the node(s) as well when it does that | 19:16 |
| sean-k-mooney | mgoddard_: hyperthreading is a bios config option and should work but nova does not allow you to enable hyperthreading as a flavor extra spec | 19:16 |
| dansmith | (and thus placement( | 19:16 |
| sean-k-mooney | mgoddard_: the closest you have to that is setting the tread count in the cpu topology extra specs | 19:16 |
| *** david-lyle has joined #openstack-nova | 19:17 | |
| mriedem | i didn't realize that service_destroy also deleted the related compute node record | 19:17 |
| cfriesen | me either...had to go read the code. | 19:17 |
| *** hemna_ has joined #openstack-nova | 19:18 | |
| dansmith | cfriesen: I thought you said it didn't? | 19:18 |
| mriedem | ok so if service delete also deletes the compute node record, then yeah we should also remove the compute node RP in placement | 19:18 |
| mriedem | i said deleting the service didn't delete the compute node record | 19:19 |
| dansmith | oh okay | 19:19 |
| mriedem | there was some bug about a year ago we were both talking about this | 19:19 |
| mriedem | but https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L404 | 19:19 |
| cfriesen | I should be able to open a bug and post a WIP fix later today | 19:21 |
| mriedem | https://github.com/openstack/nova/commit/f0d44c5b09f3f3c84038d40b621bb629a1f8110e#diff-3104166b3e802b86db6c5fa92ad08f43 | 19:21 |
| mriedem | ^ is why i thought this | 19:21 |
| mriedem | see the exchange between myself and alex | 19:23 |
| mriedem | so in this case, they deleted the service (and compute node record) but didn't stop the nova-compute service, | 19:24 |
| mriedem | so it re-created the compute node record | 19:24 |
| *** hongbin has quit IRC | 19:25 | |
| mriedem | so in that bug, when they listed compute nodes, the api tries to find the related service which was deleted and the api blows up | 19:25 |
| mriedem | because you don't recreate the service until you restart the service | 19:25 |

| melwitt | urgh right | 19:27 |
| melwitt | got focused only on the april vacation dates | 19:27 |
| mriedem | cfriesen: yeah so to summarize that, deleting the service deletes the compute node record, and the compute node record shouldn't show back up unless the service is running | 19:27 |
| dansmith | ...and we should delete the RP in placement | 19:28 |
| mriedem | what about the host mapping? | 19:28 |
| mriedem | that's also orphaned right? | 19:28 |
| dansmith | we probably should delete it in placement before we delete in our db even | 19:28 |
| dansmith | yeah | 19:28 |
| mriedem | so, | 19:28 |
| *** yamamoto has joined #openstack-nova | 19:29 | |
| mriedem | 1. delete RP in placement (because if we fail to delete the compute node or the service, it will get re-created), | 19:29 |
| mriedem | 2. delete the service/node, | 19:29 |
| mriedem | 3. delete the host mapping | 19:29 |
| mriedem | ? | 19:29 |
| dansmith | well, 1. also because if we fail, they can't do it again if we delete the local entry | 19:29 |
| *** frickler has quit IRC | 19:29 | |
| dansmith | technically, we can find the service record again if we delete the host mapping, | 19:30 |
| dansmith | so probably good to delete that first, then node, then service last of all | 19:30 |
| cfriesen | what's the host mapping used for? | 19:30 |
| dansmith | so placement, mapping, node, service | 19:30 |
| dansmith | cfriesen: finding it by name in a cell | 19:30 |
| mriedem | cfriesen: to map the host | 19:30 |
| cfriesen | ah, right | 19:30 |
| mriedem | node and service are in the same db api call, | 19:30 |
| *** frickler has joined #openstack-nova | 19:30 | |
| mriedem | unless we delete the compute node record(s?) directly in the api | 19:30 |
| mriedem | which would be my preference b/c the auto/implicit delete in the db api is kind of gross | 19:31 |
| dansmith | same db call, but node could go first | 19:32 |
| dansmith | but yeah, don't so much care about those two, | 19:32 |
| dansmith | as I'm not sure there are any FKs that would prevent us from deleting one and not the other | 19:32 |
| *** yamamoto has quit IRC | 19:33 | |

| mriedem | also, | 19:35 |
| mriedem | i think you could re-discover the compute host in another cell, | 19:35 |
| dansmith | true | 19:35 |
| mriedem | and then the old host mapping would be pointed at the wrong cell | 19:35 |

| mriedem | cfriesen: could happen in compute api code too, doesn't matter a ton to me | 19:49 |
| mriedem | cfriesen: note that this will also need an upgrade impact release note because the api will now require placement to be configured to do this | 19:49 |
| *** mgoddard_ has quit IRC | 19:50 | |
| mriedem | i think we should backport this though...so not sure how sticky that gets | 19:50 |
| cfriesen | mriedem: if placement isn't configured, wouldn't it be okay to just continue on since there wouldn't be any records? | 19:50 |
| mriedem | i mean [placement] configured specifically in the nova.conf you're running against nova-api, | 19:51 |
| mriedem | which hasn't technically required placement before this | 19:51 |
| mriedem | as far as i know | 19:51 |
| mriedem | conductor, compute and scheduler all require placement already, but api doesnt | 19:51 |
| cfriesen | ah, got it. I guess that'd be one advantage of doing it in nova-compute | 19:51 |
| mriedem | there is no rpc cast from api to compute to delete itself | 19:51 |

| edleafe | I can pair with someone on that | 20:01 |
| cfriesen | mriedem: on the mixed baremetal/hypervisor scheduler thing, I suspect the NUMATopologyFilter is actually okay as long as we don't have spec_obj.numa_topology | 20:01 |
| *** eharney has quit IRC | 20:02 | |
| *** Zames has quit IRC | 20:03 | |
| mriedem | cfriesen: in that case the filter should just filter out an ironic host/node | 20:03 |
| mriedem | but that's what i was trying to figure out | 20:03 |
| mriedem | i.e. if NUMATopologyFilter just doesn't work with an all ironic deployment, then don't enable it, but if you're using a single scheduler for mixed VM/BM, that filter would also kick out requests for numa for ironic hosts in the deployment, | 20:04 |
| mriedem | but i think that should be ok? | 20:04 |
| cfriesen | mriedem: as long as requests for ironic instances don't specify a desired numa topology then I think it should be good | 20:04 |
| mriedem | if we have a libvirt and ironic host as candidates, the ironic would is filtered out and the libvirt one should be ok | 20:04 |
| cdent | edleafe: have you got something queued up after member_of? | 20:04 |
| mriedem | cfriesen: well yeah, baremetal flavors shouldn't have numa things in them | 20:05 |

| cfriesen | tssurya: for your review at https://review.openstack.org/#/c/546660 should we also delete the "service" records along with the compute node records? | 20:49 |
| cfriesen | tssurya: if you want to submit a patch for that bug, go for it. I probably won't get to it till late next week at the earliest | 20:49 |
| tssurya | cfriesen : yea, sure I can work on it | 20:50 |
| tssurya | regarding removal of "service" records, when I guess it makes sense to do when force deleting the cell and host | 20:51 |

| openstackgerrit | Lance Bragstad proposed openstack/nova master: Add scope_types to server policies https://review.openstack.org/525772 | 20:51 |
| mriedem | this gets quite messy | 20:52 |
| mriedem | because deleting a compute service in the api today also removes the compute host from any aggregates it's in | 20:52 |
| tssurya | yes it will get messy, | 20:52 |
| *** dave-mccowan has quit IRC | 20:53 | |

| mriedem | where does it end | 20:53 |
| *** mvk has quit IRC | 20:53 | |

| mriedem | Kevin_Zheng_: you reported the bug related to this https://blueprints.launchpad.net/nova/+spec/add-server-group-remove-member-notifications but for telemetry and searchlight - given the states of those projects, do they actually care about solving this now? | 21:59 |

| dansmith | mriedem: it requires conf | 22:00 |
| dansmith | so I would kinda expect not | 22:00 |
| dansmith | we will backport it because it's important enough, but I don't know that it fits the usual backport candidate mold | 22:00 |
| mriedem | we can backport bug fixes sometimes as long as the config doesn't change any default behavior | 22:00 |
| *** tbachman has joined #openstack-nova | 22:00 | |
| dansmith | it should be safe from that regard | 22:00 |
| dansmith | it's really a feature used to fix a bug, IMHO, | 22:01 |
| mriedem | by "we will backport" you mean the royal we? | 22:01 |
| dansmith | so a bp isn't wrong I don't think | 22:01 |
| dansmith | mriedem: we as in redhat | 22:01 |
| mriedem | that's what i meant :) | 22:01 |
| *** moshele has quit IRC | 22:01 | |
| mriedem | alright i guess people that want it in stable can always patch out of tree if we're not going to backport upstream | 22:02 |
| *** danpawlik has joined #openstack-nova | 22:02 | |
| dansmith | I'm not saying we can't or shouldn't | 22:02 |
| mriedem | i heard windriver has already had this for a year | 22:02 |
| *** rcernin has joined #openstack-nova | 22:02 | |
| dansmith | I would have expected you to say no | 22:02 |
| dansmith | if you think it's legit, then I think it's reasonable | 22:02 |
| mriedem | having a blueprint tag on it makes it more awkward to backport | 22:02 |
| *** danpawlik has quit IRC | 22:02 | |
| dansmith | well, | 22:02 |
| mriedem | i don't have the context on the thing, | 22:02 |
| dansmith | it's not a bug in nova | 22:02 |
| mriedem | just saw 'meltdown' | 22:02 |
| dansmith | it's a bug in .. I dunno.. the whole arrangement of things | 22:03 |
| *** tssurya has quit IRC | 22:03 | |
| mriedem | in computers? | 22:03 |
| mriedem | just say computers | 22:03 |
| dansmith | nova doesn't let you specify a thing that only the operator can know, and is needed to mitigate performance loss after applying the meltdown fixes | 22:03 |
| dansmith | it's completely a nova feature, | 22:03 |
| dansmith | but operators will need it to fix a bug or regressed behavior in lots of other things (kernel, qemu, etc) | 22:03 |
| mriedem | hmm, this reminds me, | 22:04 |
| mriedem | stable/ocata and stable/pike started crapping recently (right before the ptg) because of qemu / libvirt package updates for CVEs related to meltdown and spectre in the UCA | 22:04 |
| dansmith | so I guess I'd leave it as a bp and just call it out in the backport as why we're making an exception | 22:04 |
| mriedem | mnaser: ^ | 22:04 |
| mriedem | you might be interested in that | 22:05 |
| mriedem | https://review.openstack.org/#/c/534384/ | 22:05 |
| *** liverpooler has quit IRC | 22:05 | |
| * mnaser looks | 22:05 | |
| mriedem | mnaser had to patch devstack on ocata and pike specifically to wait longer for nova-compute to start up b/c libvirt startup was going from like 10 seconds to a minute | 22:06 |
| mriedem | dansmith: ^ sound like the same issue? | 22:06 |
| dansmith | libvirt startup .. meaning a guest? | 22:06 |
| *** burt has quit IRC | 22:06 | |
| mriedem | no, libvirtd | 22:06 |
| mriedem | or the connection to libvirt | 22:06 |
| *** liverpooler has joined #openstack-nova | 22:06 | |
| dansmith | mm, I dunno, that's a question for kashyap I think | 22:07 |
| dansmith | maybe if the fixes have been applied on the host, | 22:07 |
| dansmith | but pcid isn't passed it makes our guests just super slow for some things | 22:07 |
| mriedem | https://review.openstack.org/#/c/547676/ | 22:07 |
| dansmith | so it could be | 22:07 |
| mriedem | https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/ocata-staging/+sourcepub/8774271/+listing-archive-extra | 22:07 |
| mriedem | the libvirt cve is i nthere | 22:07 |
| dansmith | I mean, that's what the assertion is about the problem we're trying to solve | 22:07 |
| dansmith | that _some_ things are like 30+% slower after the fixes | 22:07 |
| *** gjayavelu has joined #openstack-nova | 22:08 | |
| mnaser | so the reason why it affected ocata and pike was because first of all devstack didnt use pike uca in pike, it used ocata uca | 22:08 |
| mnaser | and the older release of uca didn't have this feature where it could ask qemu what cpu features it supported | 22:08 |
| mnaser | so on libvirt start up with older libvirt instances, it would boot up a very small tiny qemu instance to probe it for things like cpu features etc | 22:09 |
| *** tssurya has joined #openstack-nova | 22:09 | |
| dansmith | dear god | 22:09 |
| mnaser | which would make the start up super sloooow | 22:09 |
| *** masber has joined #openstack-nova | 22:09 | |
| dansmith | so that's unrelated I believe, unless the need for the new cpu feature discovery was because of the meltdown patch, | 22:09 |
| dansmith | but I expect kashyap's fix won't solve that as it's a qemu-missing-a-thing problem | 22:10 |

| melwitt | mriedem: are you cool with the cpu model flags bp and the idea of backporting it? | 22:37 |
| mriedem | i'm not crazy about it being a bp if we know we're going to backport it | 22:37 |
| mriedem | i'd rather pretend it's not and say it's a bug fix | 22:38 |
| *** yamamoto has quit IRC | 22:38 | |
| mriedem | https://review.openstack.org/#/c/534384/5//COMMIT_MSG@28 definitely makes it sound feature-y too though | 22:39 |
| mriedem | "besides the fix, you can also configure nova for other goodies!" | 22:39 |
| melwitt | heh. yeah. this is definitely an odd case | 22:39 |
| mriedem | now, if pcid as the extra flag is the only thing you'd care about if you only care about the fix, | 22:40 |
| mriedem | then this could be a [workarounds] option with a boolean to set pcid or not, | 22:41 |
| mriedem | and backport that | 22:41 |
| mriedem | then the free-form wild west extra flags thing that is more of a feature could only be master | 22:41 |
| mriedem | and we'd deprecate the workaround in master | 22:41 |
| mriedem | dansmith: ^ what do you think about that? | 22:42 |
| dansmith | I dunno, it seems like too much concern over a relatively minor thing | 22:44 |
| dansmith | and I kinda expect that we'll backport the main thing ourselves anywaym | 22:44 |
| *** mvenesio has joined #openstack-nova | 22:44 | |
| dansmith | just so that people with queens and people with rocky don't need a different fix for this | 22:44 |
| dansmith | but if that's how it has to go, then okay | 22:44 |
| mriedem | i'm not the ptl, not my say, but i'd be more comfortable with that | 22:46 |
| * mriedem watches that bus go by | 22:46 | |
| dansmith | I guess my point is, | 22:46 |
| dansmith | we're going to backport the meat of the feature anyway, because we need it for the workaround | 22:46 |
| dansmith | and constraining the workaround to one flag doesn't really do anything to make it safer, | 22:47 |
| dansmith | unless the operator is going to just do crazy stuff with it (not sure what that would be even), | 22:47 |
| mriedem | ^ is what i'm worried about, they try the 'other use cases' in stable, | 22:47 |
| mriedem | and are all of a sudden reporting bugs about it | 22:47 |
| dansmith | but if they're going to do that, | 22:47 |
| dansmith | they'll do it with rocky when it's out | 22:47 |
| *** dave-mccowan has quit IRC | 22:48 | |
| dansmith | if we have a workaround, then people have to set that to make the thing work, and then when they roll to rocky (or S) and performance regresses for some reason they forgot about, | 22:48 |
| dansmith | there will be bugs where we tell them that that workaround was a one-time deal and now they have to set pcid in this other field | 22:48 |
| dansmith | just seems like it's too much monkeywork so we don't have a blueprint on a backport, | 22:48 |
| mriedem | well, we'd use the workaround if it were set while it's deprecated, but we'd mark it deprecated to drop it later, but you'd have rocky to transition your tooling | 22:48 |
| dansmith | when we can clearly point to not-our-fault reasons why this is needed and not high risk | 22:48 |
| dansmith | yeah, it just doesn't seem worth the pain to me | 22:49 |
| *** chyka has joined #openstack-nova | 22:49 | |
| mriedem | precedent is another concern for me here, | 22:49 |
| mriedem | true it's a no-op by default, | 22:49 |
| cfriesen | dansmith: I agree with you, but I also suspect someone is going to try enabling pdpe1gb or vmx on queens. | 22:49 |
| mriedem | but then people could use that justification against us later | 22:50 |
| dansmith | cfriesen: so? | 22:50 |
| melwitt | the workaround idea seems good until we get to the point where people would have to go from workaround -> full feature to not regress performance | 22:50 |
| cfriesen | dansmith: so mriedem's point about it likely causing more bug reports against stable | 22:50 |

| mriedem | melwitt: it's just updating your configs in rocky | 22:50 |
| dansmith | cfriesen: but those bug reports will be against whatever release we allow the full feature in | 22:50 |
| mriedem | to not use the deprecated option | 22:50 |
| *** hongbin has quit IRC | 22:50 | |
| dansmith | mriedem: every time we do that it's upgrade pain and it just seems like we have too much of that already | 22:51 |
| cfriesen | dansmith: not necessarily, nested vmx for example is buggy in older systems but may be stable by the time rocky is released | 22:51 |
| melwitt | mriedem: but wouldn't you also have to add "pcid" to your rocky config elsewhere then? | 22:51 |
| dansmith | I get the precedent thing | 22:51 |
| mriedem | melwitt: yes, you'd do it on the new option | 22:51 |
| dansmith | cfriesen: that's a super weak reason :) | 22:51 |
| dansmith | cfriesen: because (a) I don't think it will be and (b) people can already do crazy stuff with lots of options | 22:52 |
| dansmith | cfriesen: you could work around this by just defining your own cpu models in the libvirt system xml, and you can do way crazier stuff to your systems that way | 22:52 |
| cfriesen | dansmith: true enough. for what it's worth, adding pdpe1gb seems to be generally fine. | 22:52 |
| dansmith | heh | 22:53 |
| cfriesen | for the subset of intel hosts I've dealt with anyway | 22:53 |

| melwitt | we can just slap "experimental" on it on the backport, use at your own risk | 22:54 |
| dansmith | it's not experimental but sure :) | 22:54 |
| dansmith | melwitt: I need to be done for the day anyway, | 22:55 |
| melwitt | well, what I mean is if you use it and it breaks something in queens/pike/ocata then we're probably not going to fix things to accommodate the various flags they enable | 22:55 |
| dansmith | so you make the call, my input is all above | 22:55 |
| dansmith | melwitt: it won't be any less experimental later, | 22:55 |
| dansmith | it just lets you choose cpu flags | 22:56 |
| dansmith | it will be just as dangerous in five years if you use it wrong | 22:56 |
| melwitt | okay | 22:56 |
