| bauzas | hrw: you might be interested in https://bugs.launchpad.net/nova/+bug/1741319 | 08:10 |
| openstack | Launchpad bug 1741319 in OpenStack nova-compute charm "arm64: Migration pre-check error: CPU doesn't have compatibility." [Medium,Incomplete] | 08:10 |
| bauzas | hrw: just let me know if that's a valid bug so I can triage it | 08:10 |
| hrw | bauzas: there is no cpu_model = host-model on aarch64 | 08:11 |
| *** slaweq has quit IRC | 08:11 | |
| hrw | bauzas: so bug is valid and not solvable | 08:12 |
| *** amorin has left #openstack-nova | 08:12 | |
| bauzas | hrw: that's what I understood | 08:12 |
| bauzas | since we compare models for live migrating | 08:12 |
| *** amoralej|off is now known as amoralej | 08:13 | |
| *** annp has quit IRC | 08:14 | |
| *** hoangcx has quit IRC | 08:14 | |
| hrw | added note | 08:14 |
| *** annp has joined #openstack-nova | 08:14 | |
| *** hoangcx has joined #openstack-nova | 08:15 | |
| bauzas | hrw: so, for the moment, live-migration isn't supported for ARM64, I guess then | 08:15 |
| bauzas | if so, we should amend the doc | 08:15 |
| hrw | bauzas: not quite. | 08:15 |
| hrw | bauzas: you may migrate but between same cpus | 08:16 |
| *** alexchadin has joined #openstack-nova | 08:16 | |
| hrw | will ask our testers to check it (as my setup is all-in-one) | 08:16 |
| bauzas | hrw: the reporter says they have exact CPUs | 08:17 |
| bauzas | exact same* | 08:17 |
| *** slaweq has joined #openstack-nova | 08:17 | |
| bauzas | hrw: but the point is, nova is checking something that ARM64 libvirt doesn't pass, that's ity | 08:17 |
| hrw | ok | 08:17 |
| bauzas | so that probably needs some kind of discussion about the possible solutions | 08:18 |
| bauzas | we could conditionally don't care of cpu models if arm64 | 08:18 |
| bauzas | or we could ask libvirt to provide a single one | 08:18 |
| bauzas | I tend to consider the latter as the best one | 08:18 |
| hrw | the problem is that even kernel does not provide cpu model | 08:19 |
| bauzas | I know | 08:19 |
| hrw | /proc/cpuinfo is useless | 08:19 |
| bauzas | it's all about having the same XML | 08:19 |
| hrw | DMI data is useless too | 08:19 |
| bauzas | hence the interface | 08:19 |
| hrw | bauzas: you can not set 'random' values as cpu model. that's why libvirt does not set that at all | 08:20 |
| *** slaweq has quit IRC | 08:22 | |
| bauzas | I see | 08:22 |
| *** threestrands has quit IRC | 08:22 | |
| bauzas | hrw: anyway, I leave the bug one | 08:22 |
| bauzas | open* | 08:22 |
| hrw | sure | 08:23 |

| cgoncalves | sean-k-mooney: I'd like to check if my understanding from your review of https://review.openstack.org/#/c/533713 is correct. instead of extending VIFBridge and VIFOpenVSwitch you're saying adding a new VIFTap. if that is the case, the should_provide_port would not be needed at all as the TAP device (VIFTap) would be created | 12:12 |
| *** pcaruana has joined #openstack-nova | 12:13 | |
| cgoncalves | sean-k-mooney: request of attachment of the TAP device (or VIFVeth, VIFGre, etc) would be by setting vif.network.bridge, right? | 12:13 |
| sean-k-mooney | cgoncalves: oh hi sorry i have been meaning to get back to that review. am no i have some draft commets that ill publish later but in essence the os-vif vif objects are ment to carry only the infomation reqiured by a vif that is independet of the network backend that vif is uesed with | 12:14 |
| *** slaweq has joined #openstack-nova | 12:14 | |
| sean-k-mooney | cgoncalves: so instead of putting the should_provide_port in the VIF it should in in the port profile as the port porfiled is backend specific | 12:14 |

| sean-k-mooney | cgoncalves: i just published the comments i had pending but not sure if i finished them but does that make sense? | 12:19 |

| cgoncalves | sean-k-mooney: actually for the use case I have at hands a veth would make more sense | 12:19 |
| sean-k-mooney | cgoncalves: well it can only be attached to one or the other at any one time | 12:19 |

| cgoncalves | sean-k-mooney: application on the host | 12:22 |
| sean-k-mooney | cgoncalves: in that case you want to use an ovs internal port. | 12:22 |
| cgoncalves | sean-k-mooney: the use case is the octavia health manager that listens for heart beats sent from service vms connected to a neutron network | 12:22 |
| cgoncalves | sean-k-mooney: correct, hence the should_provide_port in VIFOpenVSwitch that would create such ovs internal port | 12:23 |
| *** lpetrut has joined #openstack-nova | 12:23 | |

| cgoncalves | sean-k-mooney: os-vif would take care of L1-l2 (incl. set of mac addr) and the app would set IP addressing | 12:24 |
| cgoncalves | sean-k-mooney: right, that was what I get from your review | 12:24 |
| *** AlexeyAbashkin has quit IRC | 12:25 | |
| cgoncalves | sean-k-mooney: so in that case a VIFOpenVSwitchInternalPort obj would make sense, plus the vif.network.bridge (or vif.profile.bridge?) set so that the plugin knows where to create the port | 12:25 |
| cgoncalves | the same would be valid for e.g. VIFTap, VIFGre, VIFVeth, etc | 12:26 |
| sean-k-mooney | cgoncalves: an ovs internal port cannont be use by a vm which is why it would be different form VIFOpenVSwitch with should_provide_port set in the port profile | 12:26 |
| cgoncalves | sean-k-mooney: I'm not looking to use an ovs internal port by a vm, but by an app in the host | 12:27 |
| sean-k-mooney | cgoncalves: yes VIFOpenVSwitchInternalPort wiht bridge set in the os-vif network object would be correct way to go | 12:27 |
| sean-k-mooney | or perhap VIFInternal the name is long enough as it is | 12:28 |

| sean-k-mooney | wanghongtao do you see any error in the libvirt instance log? it should be under /var/log/libvirt/qemu/instance... | 12:36 |
| cgoncalves | sean-k-mooney: FYI this is what i would like to get rid of by leveraging os-vif: https://github.com/openstack/octavia/blob/master/devstack/plugin.sh#L316-L344 | 12:36 |
| sean-k-mooney | cgoncalves: well os-vif would be setting the neutron port uuid for the port in the external_id filed of the ovsdb so neutron shoudl add the security groups if you are using the openvsiwthc security gorup driver. | 12:38 |
| sean-k-mooney | cgoncalves: but you are correct if you were using iptables you would need to do hybrid_plug | 12:38 |
| *** jpena is now known as jpena|lunch | 12:39 | |
| sean-k-mooney | cgoncalves: e.g. crate tap/veth in linux bridge and connect that lb to ovs | 12:39 |

| *** acormier has joined #openstack-nova | 12:40 | |
| cgoncalves | sean-k-mooney: right. in that case it would make much sense to name the vif VIFInternal because there would be any ovs internal port created | 12:44 |

| sean-k-mooney | wanghongtao: ah nova has a periodic check in the compute to see if vms are still running. if it finds that they are not i belive it updates the state in the db to reflect that but i dont think it work the other way? dansmith melwitt stephenfin might be able to confirm | 12:48 |
| sean-k-mooney | cgoncalves: well a os-vif vif object is not the same as a neutron vif type. the neutron vif_ovs + hybrid_plug=false is mapped to VIFOpenvswitch but vif_ovs + hybrid_plug=true is VIFBridge | 12:50 |

| sean-k-mooney | wanghongtao: yes and before you stoped it with virsh stop it was active in nova correct | 12:54 |
| *** acormier has joined #openstack-nova | 12:54 | |
| sean-k-mooney | if nova sees a vm is running and is marked as stopped in its db it will stop the vm. | 12:55 |
| sean-k-mooney | if nova think a vm is running and discovers its stopped i think it updates it db to mark it as off. | 12:56 |
| sean-k-mooney | so what i think happended is nova and libvirt both agreed the vm shoudl be running, then you stoped it with virsh and nova noticed and updated its db. then you started it with virsh and nova stopped it because it thinks it should not be running. | 12:58 |

| efried | stephenfin: Is the multi-numa-node guest thing only crucial for the PCI device aspect? | 13:23 |
| efried | stephenfin: And in that case, you don't want anti-affinity for anti-affinity's sake; you just want the ability to get your devices from different NUMA nodes as necessary (cause otherwise you wouldn't have enough / the right ones available). Right? | 13:24 |
| sean-k-mooney | efried: i think he is at lunch but there are other reason to use multi numa node guest | 13:24 |
| sean-k-mooney | efried: e.g. large guest with more cpus then are availabel on a singel numa node when useing hugepages | 13:25 |
| sean-k-mooney | efried: increased memory bandwidth | 13:25 |
| *** masahisa has quit IRC | 13:25 | |
| efried | sean-k-mooney: So what, in that CPU case you would want affinity for "as many CPUs as possible" but allow the rest to bleed into other NUMA nodes? | 13:25 |
| efried | sean-k-mooney: Or would it be sufficient in that case to say "no CPU affinity" and just let 'em spread out? | 13:26 |
| sean-k-mooney | efried: no in the flavor extraspec you can specify how many cpus are assigned to each virtual numa node | 13:26 |
| efried | sean-k-mooney: By what, naming the NUMA node? | 13:26 |
| efried | So you could still get away with something that finicky using traits. | 13:27 |
| efried | You could even do it so you didn't necessarily have to target a specific host, possibly. | 13:27 |
| *** READ10 has joined #openstack-nova | 13:27 | |
| sean-k-mooney | efried: nameing the virtual numa nodes we have a nodeX sysntax where X is an integer starting at 0 | 13:27 |
| sean-k-mooney | the virtual number has no baring in phyical numa nodes on the host | 13:27 |
| efried | sean-k-mooney: Just so - use a trait for that, plus granular request groups, and you can get away with that. | 13:28 |
| efried | sean-k-mooney: You wouldn't use the affinity concept at all in that case. | 13:28 |
| sean-k-mooney | efried: you would use affinity to tie memory form a numa node to cpus for a numa node | 13:28 |
| sean-k-mooney | e.g. 8 vpcu with 2G or ram guset with 2 numa nodes each with 4 cores and 1G of ram | 13:29 |
| efried | sean-k-mooney: I have to run, but would you mind scribbling down a concrete use case or two for this? | 13:29 |
| efried | I want to make sure we can cover it one way or the other. | 13:30 |

| dansmith | kashyap: I've already replied | 15:34 |

| kashyap | dansmith: So here's even _more_ source-code deep dive discussion with Eric Blake, on that parameter: https://kashyapc.fedorapeople.org/virt/libvirt-bandwidth-API-parameter.txt | 15:34 |
| kashyap | I cleaned up IRC conversation with Eric (libvirt / QEMU dev) on OFTC. And posted it there. | 15:35 |
| kashyap | I learnt interesting things. I'm going to post an upstream libvirt API doc. These semantics should be documented. | 15:35 |

| efried | mriedem: Yeah, mordred would love you for that. | 15:54 |
| mriedem | hrw: my point in that comment was i don't think docs is good enough, which is why we have the min version check per arch when the driver starts up | 15:54 |

| bauzas | you can achieve that with a single curl script | 16:59 |
| melwitt | bauzas: it's not that, it's that the InstanceGroup.get_hosts method doesn't query all cells, so it won't pick up any group members in a multi-cell environment | 17:00 |

| bauzas | couldn't we just look at the instance mappings ? | 17:03 |

| *** lpetrut has quit IRC | 17:04 | |
| bauzas | melwitt: because the instance/host relationship is stored in the child DB | 17:05 |
| bauzas | since RequestSpec doesn't tell where your instance is located (fortunately) | 17:05 |
| melwitt | oh, right | 17:05 |
| mriedem | yeah the instance mapping record has no association to the host mapping record | 17:06 |
| bauzas | melwitt: what we could optimize tho is the scatter-gather method you wrote to only check the related cells by looking at the instance mappings table | 17:06 |
| mriedem | melwitt: so this looks ok, but we can skip cell0 in your scatter/gather call | 17:06 |

| stephenfin | i.e. a quick way to build releasenotes that have changed in the past release | 17:12 |
| stephenfin | rather than everything, every time | 17:12 |

| mriedem | just got back from lunch | 20:03 |
| cdent | such shame | 20:03 |
| mriedem | oh i see it's your fault | 20:04 |
| mriedem | geez | 20:04 |
| cdent | mriedem: but once I fixed that I started running with 20 hypervisors and launching 1000s of instances. ran into the rpc timeouts you did. rabbit is a pig, the conductors eats all the cpu, placement does not sweat | 20:05 |
| cdent | yeah, my bad, three years ago | 20:05 |
| mriedem | cdent: rpc timeouts for select_destinations? | 20:05 |
| cdent | hold, lemme check | 20:06 |
| mriedem | that's what i was hitting at sone point, b/c select_destinations is an rpc call, and when you're booting 1000 instances at once, we timeout on that call | 20:06 |
| dansmith | cdent: I think devstack by default configures few workers per core which is unlike a real deployment, so with thousands of real builds you'll be pushing pretty hard on a small system | 20:06 |
| mriedem | devstack is i think ncpu / 2 | 20:06 |
| mriedem | for each service | 20:06 |
| mriedem | that has multiple workers | 20:07 |
| dansmith | yeah | 20:07 |
| mriedem | if you did ncpu workers per service, which devstack used to do, you get OOM | 20:07 |
| dansmith | right | 20:07 |
| *** pcaruana has quit IRC | 20:07 | |
| *** slaweq has joined #openstack-nova | 20:08 | |
| cdent | yes in select_destinations | 20:08 |
| mriedem | yeah for that issue i had put some thoughts in https://review.openstack.org/#/c/510235/ | 20:08 |
| mriedem | but very much quarter baked | 20:08 |
| cdent | dansmith: I'm multinode, using the fake driver, and I'm in the process of now of moving all the nova-compute action to a separate host. the control plane host is 16GB and 16 cores | 20:09 |
| cdent | rabbit is eating a _ton_ of ram, followed by mysql | 20:10 |
| dansmith | ah fake driver, well, that might be different | 20:10 |
| dansmith | cdent: do you have notifications disabled? | 20:10 |
| *** slaweq has quit IRC | 20:10 | |
| cdent | no, but that's an excellent idea | 20:10 |
| dansmith | cdent: otherwise I think you're just filling a queue with no consumer | 20:10 |
| cdent | thanks | 20:10 |
| dansmith | thank me if/when it matters :P | 20:10 |
| *** slaweq has joined #openstack-nova | 20:10 | |
| mriedem | that's something i've been wondering about benchmarking lately, | 20:11 |
| mriedem | with and without versioned notifications enabled | 20:11 |
| mriedem | by default, we have both versioned and unversioned notifications enabled, | 20:11 |
| mriedem | and versioned notifications do a lot of lazy-loading of fields to build the notification payload | 20:11 |
| cdent | well it's a good idea nonetheless as I'm trying to remove as much stuff I don't care about™ as possible | 20:11 |
| cdent | and at the moment, notifications are basically noise | 20:12 |
| mriedem | yeah - take a note of what impact disabling that makes if you can | 20:12 |
| mriedem | i.e. we might want to consider changing the default | 20:12 |
| mriedem | looks like we might have a rogue unit test http://logs.openstack.org/74/541474/2/check/openstack-tox-py27/a6dfdf8/testr_results.html.gz | 20:14 |

| openstackgerrit | Merged openstack/python-novaclient master: Fix listing of instances above API max_limit https://review.openstack.org/534222 | 20:47 |
| dansmith | mriedem: that would match "v2." right? | 20:48 |
| dansmith | and it would also match "myapi-123.novav2.foo.com" | 20:48 |
| mriedem | farq yes it will | 20:48 |
| mriedem | i'm basically copying the existing glanceclient utility http://git.openstack.org/cgit/openstack/python-glanceclient/tree/glanceclient/common/utils.py#n383 | 20:49 |
| mriedem | well, | 20:49 |
| *** dave-mcc_ has quit IRC | 20:49 | |
| mriedem | you can always use CONF.glance.api_servers (like everyone has had to forever) if you don't like it | 20:49 |
| dansmith | I guess we do this a lot, but re magic replacements on the url we don't control is playing with fire | 20:49 |
| mriedem | i know | 20:50 |
| mriedem | how about | 20:50 |
| mriedem | >>> re.sub('/v\d+\.?\d*', '/', url) | 20:50 |
| mriedem | 'http://23.253.94.203/image/' | 20:50 |
| *** dave-mccowan has joined #openstack-nova | 20:50 | |
| mriedem | since / is a special character, | 20:50 |
| mriedem | i don't know if it's legit to have myapi-123.nova/v2.foo.com | 20:50 |
| dansmith | it's not | 20:50 |
| mriedem | so is that a smaller fire at least? | 20:51 |
| mriedem | otherwise we have to release note this bug | 20:51 |
| dansmith | so I would group the dot and the decimal and require them together or not at all | 20:51 |
| dansmith | (\.\d+)? | 20:51 |
| dansmith | and require / at the end immediately after the last digit | 20:51 |
| dansmith | so "/v2.0oohhmy/" doesn't match | 20:52 |
| dansmith | naw mean? | 20:54 |
| mriedem | i don't regex well | 20:54 |
| mriedem | >>> re.sub('/v\d+(\.\d+)?', '', 'http://23.253.94.203/image/v2.0') | 20:55 |
| mriedem | 'http://23.253.94.203/image' | 20:55 |
| mriedem | ? | 20:55 |
| dansmith | re.sub('/\d+(\.\d+)?/', '/', url) | 20:56 |
| mriedem | that doesn't work | 20:56 |
| dansmith | hrm yeah | 20:56 |
| openstackgerrit | Merged openstack/nova master: XenAPI: Provide support matrix and doc for VGPU https://review.openstack.org/540808 | 20:57 |
| dansmith | because no trailing slash in your example | 20:58 |
| dansmith | so I guess you can't do that | 20:59 |
| mriedem | yar | 20:59 |
| dansmith | does pinning to $ work because you know it'll be the end? | 20:59 |
| dansmith | re.sub(r'/v\d+(\.\d+)?/?$', '/', 'http://thing.novav2.0oh.v2.foo/image/v2/') | 20:59 |
| dansmith | allow one trailing slash, but otherwise the v2 has to be at the end | 21:00 |
| dansmith | anyway, I'm probably being too OCD about it | 21:00 |
| mriedem | yeah that works too | 21:00 |
| *** tidwellr has quit IRC | 21:01 | |
| mriedem | i might just add a known issue release note to the patch as well, | 21:01 |
| *** tidwellr has joined #openstack-nova | 21:01 | |
| mriedem | saying, we make a best attempt given the glanceclient bug, but if it doesn't work for you, use CONF.glance.api_servers | 21:01 |

| dansmith | cdent: dang :) | 21:07 |
| cdent | so rabbit's a pig | 21:07 |
| cdent | evidently it's a pig without realy doing anything | 21:08 |

| *** elmaciej has joined #openstack-nova | 21:11 | |
| mriedem | cdent: are you sure? the default is both - did you explicitly configure it? | 21:11 |
| *** awaugama has joined #openstack-nova | 21:12 | |
| cdent | mriedem: I may be confused. As I understand both is the default only if you have 'notify_on_state_change' set to something and the default for that is to not be set. | 21:13 |
| mriedem | cdent: notify_on_state_change is only for instance updates | 21:13 |
| mriedem | we notify the shit out of you for everything else | 21:13 |
| mriedem | any action taken on an instance | 21:13 |
| mriedem | plus steady state | 21:13 |
| mriedem | "NOTIFY HI I AM STILL WORKING!" | 21:14 |
| cdent | hmmm, the docs are not helping me much here, I will try harder | 21:14 |
| mriedem | https://docs.openstack.org/nova/latest/configuration/config.html#notifications | 21:14 |
| mriedem | set notification_format=unversioned | 21:15 |
| mriedem | i guess we don't have anything for just disabling notifications altogether :( | 21:15 |
| cdent | right | 21:15 |
| cdent | thus my confusion | 21:15 |
| dansmith | mriedem: really? that's.. broken | 21:15 |
| dansmith | maybe rabbit will throw them away if there is no consumer, but I thought not | 21:16 |
| dansmith | anyway, biab | 21:17 |
| openstackgerrit | Christian Berendt proposed openstack/nova stable/ocata: live-mig: keep disk device address same https://review.openstack.org/541904 | 21:17 |
| cdent | so at the moment if I want to at least limit the volume of notifications I should change both to something else? I can at least do that | 21:17 |
| cdent | Being able to turn them off fully seems like it might be a useful thing | 21:17 |
| mriedem | https://docs.openstack.org/oslo.messaging/latest/configuration/opts.html#oslo_messaging_notifications.driver | 21:18 |
| mriedem | you could set the notification driver to 'noop' | 21:18 |
| mriedem | i guess | 21:18 |
| mriedem | however, | 21:18 |
| mriedem | nova is still generating rpc/db load just building the payloads to send them to dev/null | 21:18 |
| *** salv-orlando has quit IRC | 21:18 | |
| mriedem | cdent: for now you'd set it the format to 'unversioned' | 21:19 |
| mriedem | that's as minimal as it gets right now i think | 21:19 |
| cdent | roger that | 21:19 |

| openstackgerrit | Dan Smith proposed openstack/nova master: Make service all-cells min version helper use scatter-gather https://review.openstack.org/539590 | 22:43 |
| openstackgerrit | Dan Smith proposed openstack/nova master: Make host_manager use scatter-gather and ignore down cells https://review.openstack.org/539617 | 22:43 |
| melwitt | okay, so instead in the scheduler we should target each thing to a cell for getting the hosts? I considered that but wasn't sure how to do it if we're accessing things through a field. would we change it to assign the RequestSpec.instance_group.hosts field to the result of a scatter-gather, instead of letting it lazy-load? | 22:44 |
| melwitt | another thought is, the late affinity check is a compute host checking group members against itself and if it can't check other cells ... is that a problem? | 22:45 |
| dansmith | melwitt: you can't do the late affinity check from the comptue, | 22:49 |
| dansmith | that's been one of the caveats of cellsv2 since pike | 22:49 |
| *** itlinux has quit IRC | 22:50 | |
| dansmith | (and ocata in devstack since we run multi-level by defalt) | 22:50 |
| melwitt | guh, right. I swear I don't have enough room in my brain for all of this stuff | 22:50 |
| dansmith | melwitt: this isn't for a lazy-load though right? | 22:51 |
| dansmith | oh, we're actually hitting it via lazy load I see from the comment | 22:51 |
| dansmith | er, commit message | 22:51 |
| melwitt | dansmith: I *think* the way this is happening during scheduling is that this line causes a lazy-load and that's how we get the host list for group members https://github.com/openstack/nova/blob/master/nova/scheduler/utils.py#L700 | 22:51 |
| dansmith | so yeah, we probably need to not let that happen (i.e. make sure we pull the hosts early, or manually fill the group objects from the list with some cells-aware helper | 22:52 |
| *** slaweq has joined #openstack-nova | 22:52 | |
| melwitt | so I was thinking we need to replace that with a proper scatter-gather calling get_hosts for all cells except cell0 or something? | 22:52 |
| melwitt | yeah | 22:52 |
| dansmith | melwitt: there should be a debug log about it if there is | 22:52 |
| dansmith | melwitt: yeah, a check before that and a call to a dedicated fill routine would be easiest and cleanest I think | 22:52 |
| melwitt | there actually isn't because InstanceGroup override obj_load_attr and doesn't log a message about it, I think. /re-checks | 22:52 |
| dansmith | alternatively a non-remotable helper, but that really blurs the line more which isn't great | 22:53 |
| dansmith | ah | 22:53 |
| dansmith | well that sucks :) | 22:53 |
| melwitt | yeah, srsly | 22:53 |
| dansmith | we should fix that too | 22:53 |
