| johnsom | Hi nova folks. FYI, I opened a bug that anti-affinity appears to have been broken since at least August. https://bugs.launchpad.net/nova/+bug/1863190 Let me know if there is more information I should collect while I have the instance up and running. | 01:31 |

| melwitt | johnsom: did you boot the two instances at the same time or near the same time? did you use multi-create? | 02:09 |
| johnsom | They were close in time, but individual calls to the nova api | 02:10 |
| johnsom | Our normal active/standby boot sequence | 02:10 |
| melwitt | ok. I'm wondering if it's a race basically | 02:11 |
| *** slaweq has joined #openstack-nova | 02:11 | |
| melwitt | like if you wait for the first instance to become active and then do another request, would it fail | 02:11 |
| johnsom | Yeah, probably. This used to work. | 02:11 |
| johnsom | Yeah, I don’t know about waiting for active. That can take some time. | 02:12 |
| johnsom | We have seen that up to five minutes, mostly scheduler time. I don’t think we want to hold up the boot process for the secondary that long | 02:13 |
| melwitt | no sorry, I meant in your devstack | 02:14 |
| melwitt | I can try it later too but not tonight. I was just asking in case you had that easy environment already up | 02:15 |
| johnsom | Ah, as a test. I can try that. It will be tomorrow however, it is dinner time. Lol | 02:15 |
| melwitt | same | 02:15 |
| johnsom | If there is a list of thing you would like me to try, comment on the bug and I will run them tomorrow | 02:15 |
| melwitt | there's a thing called the "late affinity check" in nova-compute that is on by default that should handle races | 02:15 |
| melwitt | I don't know off the top of my head what could have regressed this. | 02:16 |
| *** slaweq has quit IRC | 02:16 | |
| melwitt | I'll try out some things with a devstack tomorrow to start finding out what's going on | 02:18 |

| efried | sean-k-mooney, bauzas: I'm looking at the NUMA RP spec again right now. Based on comments I skimmed on my phone, I think we might have missed the boat on the `False` thing. But checking... | 15:44 |
| *** nweinber has quit IRC | 15:44 | |
| bauzas | efried: when we discussed this with stephenfin, we agreed on splitting between non-NUMA and NUMA-aware nodes | 15:44 |
| bauzas | so, if you say 'no' for a node, then you shouldn't get NUMA-aware instances | 15:45 |
| bauzas | it's like 'no, I don't want to get a beer', but then the bar tender gives you one | 15:45 |
| efried | bauzas: exactly, and there was a design hole for that in PS21. | 15:46 |

| bauzas | efried: ok, look then at the new revision and tell me then if you see some hole | 15:50 |
| efried | bauzas: now I think I understand that you got rid of the fallback query completely, and on purpose. But that doesn't work. The upgrade issue that gibi and stephenfin identified still exists. | 15:50 |
| efried | bauzas: Specifically: without the 'fallback query', NUMA-aware flavors can't land on `None` hosts. | 15:50 |
| efried | But *with* the fallback query, NUMA-aware flavors will *also* (incorrectly) land on `False` hosts. | 15:51 |
| bauzas | efried: ah, possibly | 15:51 |
| bauzas | shit | 15:51 |
| efried | So we need a) the fallback query, and b) some other design element to fix that second problem. | 15:51 |
| efried | sean-k-mooney's suggestion of using an aggregate... that will work, but it seems like a big hammer to me. | 15:52 |
| bauzas | or using another trait then | 15:52 |
| efried | I think I would prefer marking `False` hosts with a `NO_NUMA_HERE` trait... yes | 15:52 |
| bauzas | like HW_NON_NUMA | 15:52 |
| bauzas | ok, I think we can do this | 15:52 |
| efried | It's not pretty. But it's also *temporary*. Once all computes are upgraded to V where the conf is mandatory, we can get rid of that, because we also get rid of the fallback query. | 15:52 |
| efried | please be sure to mention ^ that. | 15:53 |
| efried | sean-k-mooney: does that work for you? | 15:53 |
| bauzas | a trait for which nodes then ? | 15:53 |
| efried | for U+ nodes where the conf opt is marked False explicitly. | 15:53 |
| bauzas | for those having 'false' right? | 15:53 |
| efried | y | 15:53 |
| bauzas | ok, because then we will use the trait even after V | 15:54 |
| efried | no | 15:54 |
| efried | I mean, it wouldn't *hurt* to keep it, but it won't be needed after V. | 15:54 |
| bauzas | if so, I'd prefer to have a trait on 'none' | 15:54 |
| efried | can't | 15:54 |
| bauzas | actually you're right | 15:54 |
| efried | because we can't muck with T hosts | 15:55 |
| bauzas | and yeah we can still have the trait | 15:55 |
| bauzas | in V | 15:55 |
| bauzas | and for example, stoppint to have it when we want (V or W) | 15:55 |
| efried | We could. But we wouldn't need it anymore. But we can make that decision in V. Just mention that we *could* get rid of it if we wanted to. | 15:55 |

| gmann | efried: sean-k-mooney : sorry missed your ping on microversion need discussion. I did not read the full context but if it is failing later and change converting 2xx->4xx , then we do not need microversion. | 16:10 |
| efried | gmann: cool, thanks. | 16:11 |
| efried | not sure what you mean by 'failing later'. The failure would happen via an API check. | 16:11 |
| efried | and we're looking to convert a 4xx->2xx | 16:12 |
| efried | IOW a flavor+image combination that we would previously bounce would now be accepted. | 16:12 |
| gibi | efried, brinzhang, alex_xu: +A-d the vnc password spec | 16:12 |
| efried | thanks gibi | 16:12 |
| gmann | efried: ohk, and it is bounce currently in what situation ? | 16:13 |
| openstackgerrit | Merged openstack/nova-specs master: Add Unified Limits Spec https://review.opendev.org/602201 | 16:13 |
| efried | gmann: today you're not allowed to specify a hw:numa_nodes that would result in an uneven split, unless you also specify that split. | 16:13 |
| efried | gmann: what sean-k-mooney is proposing is to tweak the algorithm so it's able to do that uneven split for you. | 16:14 |
| *** N3l1x has quit IRC | 16:14 | |
| efried | gmann: e.g. if your flavor+image says vcpus=5, hw:numa_nodes=2, previously we would fail. With the proposed "bug fix" we would succeed and give you a 3/2 split. | 16:15 |
| brinzhang | gibi: how about "The ``delete_on_termination`` field is optional, if not specified, the server's BDM does not contains ``delete_on_termination``." | 16:15 |
| brinzhang | gibi: thanks +A for vnc passwd spec | 16:15 |
| gmann | efried: sean-k-mooney ah, got it. ok in that case, we should bump version for interoperability . | 16:16 |
| *** nweinber has quit IRC | 16:16 | |
| efried | okay. I think that makes sense. | 16:16 |
| efried | ergo, not happening in U :( | 16:16 |
| gmann | gibi: brinzhang re: delete_on_termination spec - but volume id in url is old volume and in body it is new volume so those cannot be same. | 16:17 |
| *** udesale_ has quit IRC | 16:17 | |
| brinzhang | gmann: yes, it's true | 16:18 |
| gmann | so we have to keep expecting the volume_id in request as mandatory. | 16:19 |
| gmann | considering delete_on_termination as false by default make sense for me and consider only if it is explicitly mentioned in request | 16:20 |
| brinzhang | - If only ``volumeId`` is required, just doing a swap volume. | 16:20 |
| brinzhang | - If only ``delete_on_termination`` is required, just update the voume denoted by the ``volume_id`` in the URL path not the request body. | 16:20 |
| brinzhang | these sentences make sense | 16:21 |
| brinzhang | The default value of delete_on_termination is False, doesnot impact anything of the target volume, so I also think it ok have the default value | 16:22 |
| brinzhang | gibi: what do you think? | 16:22 |
| bauzas | efried: quick question, when we ask for a forbidden trait for all request groups, can we just say '&required=!HW_NON_NUMA' or need to ask for every request group ? | 16:24 |
| bauzas | eg. &required_PROC1=!HW_NON_NUMA&required_PROC2=!HW_NON_NUMA | 16:25 |
| bauzas | or sean-k-mooney or anyone that can answer this question ^ | 16:25 |
| efried | bauzas: In this case it's for the fallback query. | 16:25 |
| openstackgerrit | Lee Yarwood proposed openstack/nova stable/rocky: Force refresh instance info_cache during heal https://review.opendev.org/679271 | 16:25 |
| efried | So it can just be in the same group with the VCPU and MEMORY_MB resources. | 16:25 |
| gmann | brinzhang: second statement seems like updating 'delete_on_termination' for already attached volume but via PUT which is nothing but swap volume API not updating the existing attachment. | 16:26 |
| bauzas | efried: no, the fallback query is literrally Train | 16:26 |
| efried | the point is we *want* to land on unreshaped hosts -- but only those with `None` | 16:26 |
| bauzas | actually, you're right | 16:27 |
| gmann | brinzhang: gibi i think, we should only target for newly replaced volume request can accept the 'delete_on_termination' for new volume. | 16:27 |
| brinzhang | gmann: you mean we donot to change the old volume's delete_on_termination? | 16:27 |
| bauzas | I'm already requiring NUMA-aware nodes, I don't need to ask in this query but in the fallback one | 16:27 |
| bauzas | efried: thanks | 16:28 |
| gmann | brinzhang: gibi sp that we can cover all the case where user can attach a volume (server boot, attach volume, swap volume) with 'delete_on_termination' info | 16:28 |
| * bauzas is fried | 16:28 | |
| efried | right, so: | 16:28 |
| efried | - U hosts with `False` we a) don't reshape, and b) mark with HW_NO_NUMA | 16:28 |
| efried | - pre-U and `None` hosts we a) don't reshape, and b) *don't* mark with HW_NO_NUMA (in the case of pre-U hosts, we couldn't mark them with anything even if we wanted to) | 16:28 |
| efried | - The fallback query *forbids* HW_NO_NUMA so we *won't* land on U/False hosts. | 16:28 |
| efried | correct | 16:28 |
| brinzhang | gmann: I know you mean, but the old volume is not support to configure the 'delete_on_termination' after it was attached, or booted(bfv) | 16:30 |
| brinzhang | gmann: I think change the old volume's 'delete_on_termination' make sense | 16:30 |
| gmann | brinzhang: but user can do it always while it was attached originally in server boot or POST /servers/{server_id}/os-volume_attachments/{volume_id} | 16:33 |
| brinzhang | gmann: I know, but it just a decision while the server booting or attaching a volume, while the server run a long time, the user may will change it. | 16:34 |
| openstackgerrit | Merged openstack/nova-specs master: Proposal for a safer remote console with password authentication https://review.opendev.org/623120 | 16:35 |
| gibi | gmann: as I read the goal of the spec is to change the delete_on_termination flag of an already attached volume. But now I see another usecase when you swap a volume then you need to define what should be the delete_on_terminate value of the new volume | 16:35 |
| gibi | brinzhang: do you need both use case? | 16:35 |
| brinzhang | gmann: In our project, we met such customers who were unwilling to suspend the virtual machine business and wanted to change the volume configuration, but were unwilling to keep mounted volumes when cleaning up the servers. | 16:36 |
| gmann | yeah, i feel later case make sense and with that we cover all cases where user can attach volume and specify the 'delete_on_termination' | 16:36 |
| melwitt | I'm just in the peanut gallery but I would think yes, do both right? if you're swapping in a new volume, you'd want to be able to say whether it should be deleted on termination | 16:37 |
| melwitt | otherwise that would be the one case where you can't say it | 16:37 |
| *** amoralej is now known as amoralej|off | 16:37 | |
| gmann | yeah, for new volume yes. but i am not getting to do it for old attached volume. or at least via this API which is nothing but swap volume. | 16:38 |
| brinzhang | Looking back at the history of the spec, we can't find a better nova API to make changes to this. The current API is suggested by mriedem. | 16:40 |
| melwitt | I think the main thing they want to do is change for old already attached volume :) but I do agree, adding this would be overloading the swap volume API (not ideal), as lyarwood mentioned on the review awhile back | 16:40 |
| gibi | brinzhang: so you confirm that you would like to have both use cases covered | 16:40 |
| gmann | true. | 16:40 |
| gmann | brinzhang: you cannot delete the attachment and re-attach with 'delete_on_termination' ? | 16:41 |
| gibi | not for bfv | 16:41 |
| *** Sundar has joined #openstack-nova | 16:41 | |
| gmann | ohk | 16:41 |
| brinzhang | gmann: of course, I can, but while the admin need to manager more than 100+ instance, it will be have some problem to maintain | 16:43 |
| gmann | i am reading the recommended use case of this API from api-ref in warning section - https://docs.openstack.org/api-ref/compute/?expanded=update-a-volume-attachment-detail | 16:43 |
| brinzhang | gibi, gmann, melwitt: so you all suggestion is only do the swap's volume to set the 'delete_on_termination' for the new volume? | 16:44 |
| gmann | and making this APIs for this new case means we are over-scoping this API which can lead this to more-confused API than it is today | 16:44 |
| gibi | brinzhang: I would be happy to support changing delete_on_terminate for attached volume I just see that gmann has a problem with the API design | 16:44 |
| gibi | as a note: my EndOfBusiness is closing really fast | 16:45 |
| gmann | https://docs.openstack.org/api-ref/compute/?expanded=update-a-volume-attachment-detail#update-a-volume-attachment | 16:46 |
| gmann | 'This API is typically meant to only be used as part of a larger orchestrated volume migration operation initiated in the block storage service' | 16:46 |
| gibi | if you can figure out a good place for this in the API I will support both use case, if there is no good place for the first case in the API then I can also support implementing only the second case in U | 16:46 |
| lyarwood | FWIW I think this is the correct place for the API | 16:46 |
| lyarwood | once we've removed the swap stiff | 16:47 |
| lyarwood | stuff* | 16:47 |
| lyarwood | I wanted to look into moving it into an instance action as with extend_volume etc | 16:47 |

| brinzhang | gmann: PUT /servers is the PS3 solution | 16:49 |
| brinzhang | Or I can say is our first idea for the 'delete_on_termination' | 16:50 |
| *** martinkennelly has joined #openstack-nova | 16:50 | |
| gmann | gibi: lyarwood brinzhang melwitt :in reality this swap volume API has been always in question and diverted the use case from it was originally. I remember one failure in this API when one of our customer were doing swap to vole2 and swap back to vol1 and so on. i do not know why :) | 16:51 |
| gibi | sorry folks I have to leave. | 16:51 |
| openstackgerrit | Brin Zhang proposed openstack/nova-specs master: Support re-configure deleted_on_termination in server https://review.opendev.org/580336 | 16:51 |
| lyarwood | gmann: yeah direct use of the API isn't supported, that's why I want to hide it behind https://docs.openstack.org/api-ref/compute/?expanded=run-events-detail#create-external-events-os-server-external-events | 16:51 |
| gmann | if we delete this API then it will be much better i think :) | 16:52 |

| efried | artom: I guess you might want to confirm that that version of sqla fixes your issue before pursuing. | 18:05 |
| artom | efried, backporting a thing to downstream queens, func test failed, since we suck and don't have an easy way to run downstream func tests locally, I figured a backport to queens might hit the same issue | 18:06 |
| artom | Instead, I hit a different one | 18:06 |

| efried | note that nova/U bumped past 0.12.0 to 0.13.0 for unrelated reasons https://review.opendev.org/#/c/690704/ so you would need a stable-only patch starting in train. | 18:06 |

| artom | gmann, yeah, no, still happening without that last change | 20:21 |
| artom | gmann, however, it seems it's only happening on my machine... | 20:22 |
| gmann | artom: until you have updated stable constraint locally or something. may be recreate tox can help ? | 20:24 |
| artom | gmann, I've been doing *nothing but* recreates :) | 20:24 |
| gmann | :) | 20:24 |
| * artom tries rm -rf'ing some "cruft" | 20:25 | |

| spatel | Does anyone know what would be the advantage of hw:cpu_thread_policy=require | 20:43 |
| spatel | currently i have default which is "prefer" | 20:44 |
| spatel | I am seeing performance issue so trying to understand what would be the advantage | 20:44 |
| efried | spatel: let me know if this doesn't help: https://docs.openstack.org/nova/latest/admin/cpu-topologies.html#customizing-instance-cpu-thread-pinning-policies | 20:48 |
| spatel | efried: i am on same page but i am trying to understand language | 20:48 |
| efried | ah | 20:48 |
| efried | this is not my area of expertise. Normally I would call on stephenfin or sean-k-mooney, but I think they're out at the moment. artom, how's your understanding here? | 20:49 |
| spatel | currently i am seeing on vm siblings are not correctly align with my physical cores... | 20:50 |
| spatel | look like cpu_thread_policy=require may fix that but wanted to understand first before i just go and play | 20:50 |
| artom | spatel, it's getting into the nitty gritty of low level CPU arch, which is not my strong point | 20:51 |
| artom | But IIUC putting workloads on thread siblings (policy=require) means the content for the hardware that's shared between the two threads | 20:52 |
| artom | I *think* there would be 2 decoding units, but a single execution unit | 20:52 |
| artom | So if your workload is CPU heavy, I would advice against putting it on thread sibligns, and use policy=isolate (at the cost of unusable CPU threads) | 20:53 |
| spatel | we are running Erlang application which is CPU and memory bound | 20:53 |
| artom | *means there's contention | 20:53 |
| artom | spatel, OK, so try `isolate`, see if there's an improvement | 20:54 |
| spatel | and i want to create single VM on single compute (want to assign all resources to vm) | 20:54 |
| spatel | artom: i am reading all other document and they are saying for performance use policy=require it will make sure your process stay with sibling.. | 20:54 |
| spatel | trying to understand this language | 20:55 |
| artom | spatel, "The presence of an SMT implementation like Intel Hyper-Threading can boost performance by up to 30% for some workloads. However, thread siblings share a number of components and contention on these components can diminish performance for other workloads." | 20:55 |
| artom | spatel, there's no magic answer, it depends on the workload | 20:55 |
| spatel | hmm! | 20:56 |

| spatel | Just FYI - i am running "qemu-kvm-ev-2.12.0-33.1.el7_7.4.x86_64" hope this version is fully stable | 20:56 |
| artom | Presumably it is, if you got from your OS's regular repos/sources | 20:57 |
| artom | But I'm not a qemu developer, so I don't know off the top of my head (and qemu developers themselves probably don't) | 20:57 |

| abaindur | hello, seeing an issue with SRIOV. When we delete a VM, it's VF is released back, but then we see the VF running DHCP. This causes the VF to get assigned an IP and change default route out of the host, screwing things up | 21:32 |
| abaindur | Dont know if this is openstack related, or NIC driver related, or some Linux setting | 21:32 |
| abaindur | Jan 30 16:36:44 compute-02 systemd: Starting DHCP interface eth40... | 21:34 |
| abaindur | NetworkManager is disabled... and the physical NIC for the VFs has NM_CONTROLLED=no and BOOTPROTO=none | 21:35 |
