| zhangtralon | sahid: If separating numa topology and hugepages, maybe we can collaborate on it | 09:43 |
| sudipto | johnthetubaguy, curious about an RT related observation. I see the following log message in the compute.log file: Total usable vcpus: 20, total allocated vcpus: 156 -- is this theoretically possible? | 09:46 |
| johnthetubaguy | sudipto: yes | 09:46 |
| johnthetubaguy | sudipto: CPU overcommit is quite a common hypervisor feature | 09:47 |
| sudipto | johnthetubaguy, yeah I mean the overcommit ratio is probably 1.5x times by default? | 09:47 |
| sudipto | This seems like a huge number to me? | 09:47 |
| sahid | johnthetubaguy: we have two backports here for kilo and juno, they seem to be reasonable in my point of view I would like to get your feeling 178072 please | 09:47 |
| sudipto | even if it's 2x times - this seems like a way off number doesn't it? | 09:48 |
| sahid | zhangtralon: i do not believe separate hugepages nad numa topology is the way we want to take | 09:48 |
| johnthetubaguy | sudipto: it depends what your users are doing, if most folks don't use all the CPU, thats maybe a great way to go | 09:48 |
| johnthetubaguy | sudipto: depends how you have decided to configure your system, I don't think we enforce CPU overcommit by default, its more a scheduler hint by default, I think | 09:48 |
| *** pixelbeat_ has joined #openstack-nova | 09:49 | |
| sudipto | johnthetubaguy, ok, sorry for asking a dumb question. Is it just controller by the quota from a user irrespective than actually being verified on the system? | 09:49 |
| sudipto | *controller = controlled. | 09:49 |
| *** dulek has joined #openstack-nova | 09:51 | |
| zhangtralon | sahid:oh, separating the numa and hugepages will take the more flexibility, users can using the numa or hugepages based on their cases. | 09:54 |
| johnthetubaguy | sudipto: there are user quotas, but thats separate to what the resource tracker enforces, it all depends how you configure it, I don't remember the details of that right now | 09:55 |
| sudipto | johnthetubaguy, ok... | 09:55 |
| johnthetubaguy | sudipto: as a Xen users, I generally only care about RAM, as I don't want ballooning, and thats the only finite resource, assuming i size flavors correctly to limit overcommit of everything else, like disk/CPU | 09:56 |

| *** fawadkhaliq has quit IRC | 09:56 | |
| johnthetubaguy | sahid: that looks like you are backporting a feature? | 09:56 |
| johnthetubaguy | sahid: if the original patch has a bug or blueprint attached, it would be much easier to understand the impact | 09:58 |
| sudipto | johnthetubaguy, hmm ok. Maybe one of the reasons why we only have a RamFilter and not the one for CPU? | 09:59 |
| sahid | yes but unforntunatly it was not the case. ok so rule is rule i'm going to abandon them. | 09:59 |
| johnthetubaguy | sudipto: I assumed we had a CPU one, but I haven't looked, feel free to add one if you want one | 10:00 |
| *** exploreshaifali has quit IRC | 10:01 | |
| johnthetubaguy | sahid: you could make the case, by a bug describing the impact, etc, and how that commit fixes it, and reference that in the cherry-pick | 10:01 |

| alex_xu | johnthetubaguy: currently all the policy enforce without target. So tenant-owner permission is done by the db. So thinking if we adding target, then we can enable user-owned permission | 13:25 |
| alex_xu | johnthetubaguy: it means the rule can be "user_id:%(user_id)s", the user only can see the vm belong to him | 13:25 |

| claudiub|2 | mriedem: I see here ( https://wiki.openstack.org/wiki/ReleaseNotes/Kilo#Hyper-V ) that "Support for generation 2 VMs" has been added. | 16:32 |
| claudiub|2 | mriedem: what do you mean? | 16:32 |
| mriedem | claudiub|2: yeah, but the spec said there was a docs impact | 16:32 |
| mriedem | claudiub|2: "The Nova driver documentation should include an entry about this topic including when to use and when not to use generation 2 VMs. A note on the relevant Glance image property should be added as well." | 16:32 |
| claudiub|2 | mriedem: ok, I'll take care of that, although that topic was pretty much covered in the spec | 16:34 |

| mriedem | johnthetubaguy: alaski: hey.... http://git.openstack.org/cgit/openstack/nova/tree/nova/virt/xenapi/image/bittorrent.py#n75 | 17:47 |
| mriedem | does rax drop some custom entry points in? | 17:47 |
| mriedem | i don't see any entry points in nova for a torrent_url | 17:47 |
| mriedem | found that by looking at what's using pkg_resources in nova, it's this and versionutils.py from oslo-incubator | 17:47 |
| mriedem | this entry point loader thing should be using stevedore now, but this looks like it's not even for anything in tree | 17:48 |
| alaski | mriedem: let me check, though I don't believe we're actually using that class at all right now | 17:50 |
| dansmith | yeah, | 17:50 |
| dansmith | I thought it ended up not being very useful or something | 17:50 |
| dansmith | forget who told me that | 17:50 |
| mriedem | leif? | 17:50 |
| dansmith | no | 17:50 |
| mriedem | can we just kill that bittorrent module then? | 17:50 |
| dansmith | dunno | 17:51 |
| alaski | I wouldn't kill the module, as it could be useful for someone. but requiring the config, and removing the entrypoints stuff would be good | 17:52 |
| alaski | if someone needs it they can add it back with stevedor | 17:52 |
| mriedem | alaski: ok, i'm on it | 17:52 |
| mriedem | after coffee | 17:52 |
| mriedem | i didn't see the config option stuff right above it | 17:53 |
| *** achanda has joined #openstack-nova | 17:54 | |
| alaski | dansmith: I think there was some difficulty with torrent libs during testing, like downloads would stop for some reason and a root cause wasn't found | 17:55 |
| dansmith | alaski: okay, I thought it was something more like it ended up saturating the wrong links, or being too unpredictable in the impacts on other resources | 17:56 |
| dansmith | *seems* like it should be a damn awesome solution though | 17:56 |
| *** mestery has quit IRC | 17:56 | |

| dansmith | mriedem: does it work? | 18:09 |
| dansmith | mriedem: in BVR, the visitor network required a sponsor to pre-generate an access code to activate it | 18:10 |

| dansmith | mriedem: you might want to try with a linux laptop too | 18:10 |

| dansmith | the level of discussion in #infra has me pretty concerned | 18:29 |
| sdague | oh, the corruption issue | 18:29 |
| dansmith | like, db corruption causing things like that ^ | 18:29 |
| *** annegentle has joined #openstack-nova | 18:29 | |
| clarkb | its not db corruption | 18:32 |

| sdague | dansmith: so... https://review.openstack.org/#/c/181420 is now 100% fail on bringing up the second cinder guest ... without an obvious reason for that failure | 18:34 |
| *** VW_ has joined #openstack-nova | 18:35 | |
| *** Sukhdev has quit IRC | 18:35 | |
| sdague | what else do we need in the dumps to help sort that out | 18:35 |
| dansmith | nice, let me catch up | 18:35 |
| dansmith | so this is 10 normal nova guestsm, | 18:35 |
| dansmith | followed by 10 BFV guests? | 18:35 |
| sdague | well, 10 and 4 | 18:36 |
| dansmith | and #2 BFV fails? | 18:36 |
| dansmith | okay | 18:36 |
| sdague | because I didn't want to consume the entire volume space | 18:36 |
| dansmith | yeah | 18:36 |
| sdague | but yes, #2 bvf fails pretty consistently from what I see in those runs | 18:36 |
| *** ZZelle has joined #openstack-nova | 18:36 | |
| dansmith | cool, this is definitely cloud-scale | 18:36 |
| dansmith | 12 guests.. should be plenty | 18:36 |
| sdague | well, also, we don't verify the first 10 | 18:36 |
| sdague | so this is the second host we've tried to ping | 18:37 |
| sdague | and ssh into | 18:37 |
| dansmith | oh | 18:37 |
| sdague | we *would* verify these later | 18:37 |
| *** zhenguo has quit IRC | 18:37 | |
| sdague | but never get that far because of early fail for the 2nd bfv to be sshable | 18:37 |
| dansmith | okay, wait, | 18:38 |
| dansmith | so we boot 10 nova guests and don't check them, | 18:38 |
| sdague | yep | 18:38 |
| dansmith | but boot two cinder guests and check those and the second one fails? | 18:38 |
| sdague | yes | 18:38 |
| dansmith | or rather, check each cinder one when we create | 18:38 |
| dansmith | was that important to get to reliable fail? not checking the nova ones | 18:39 |
| sdague | I don't know | 18:39 |
| dansmith | okay | 18:39 |
| sdague | the reason the cinder ones are checked as they are created is we ssh in and put content in the volume | 18:39 |
| sdague | to ensure that content is persistent | 18:39 |
| dansmith | and nothing is shut down right now either, so this is just upgrade-unrelated right? | 18:39 |
| sdague | so you have to do a ping loop, then an ssh loop | 18:39 |
| sdague | correct | 18:39 |
| dansmith | eff. | 18:39 |
| sdague | we're still in the create resources stage | 18:40 |
| dansmith | right | 18:40 |
| dansmith | so, I kinda wonder about not doing the cinder ones to see if we don't hit the upgrade issue without them | 18:40 |
| *** annegentle has quit IRC | 18:40 | |
| *** yamahata has quit IRC | 18:40 | |
| dansmith | as in, maybe the BFV process is causing us to be more racy with secgroups in some way that we're always borking networking somewhere in the BFV phase and noticing later? | 18:40 |
| sdague | so, I can put up a patch that does that if you like | 18:41 |
| *** annegentle has joined #openstack-nova | 18:41 | |
| dansmith | is that a crazy thought? | 18:41 |

| *** eglynn has quit IRC | 18:41 | |
| dansmith | we do a lot more waiting for things in the BFV case I think | 18:41 |
| sdague | includes the iptables dump | 18:41 |

| *** jecarey_ has joined #openstack-nova | 18:42 | |

| vilobhmm1 | the target to which the rpcserver connects to/talks to is it related to services entry in nova.services ? | 19:01 |
| dansmith | vilobhmm1: are you talking about the "target" being the rabbit server? | 19:01 |

| *** iamjarvo has joined #openstack-nova | 19:22 | |
| bauzas | dansmith: eh, we're updating a DB table each time a new service is run, but the operator can actually use an other driver but the DB one for SG :) | 19:22 |
| vilobhmm1 | bauzas : +1 | 19:22 |
| dansmith | right, but it doesn't have anything to do with the rpc bit | 19:22 |
| bauzas | dansmith: that's my point, this is confusing | 19:23 |
| openstackgerrit | Michael Still proposed openstack/nova: Move more qemu calls into virt.images I'd like to move calls to qemu into a central place because it will make it easier to work around the vagaries of qemu in a consistent manner. https://review.openstack.org/182030 | 19:23 |
| bauzas | dansmith: I'm okay if we say that the table is just for knowing the RPC servers | 19:23 |
| dansmith | it's not though | 19:23 |
| bauzas | dansmith: I'm not okay if this is for knowing if a service is up | 19:23 |
| dansmith | it really has nothing at all to do with it | 19:23 |
| jaypipes | vilobhmm1: so, the services database table really isn't involved in much of that. The different RPC services (nova-compute, nova-conductor, etc) when they start up, they pass in two variables to their Service.create() constructor: topic and binary. The topic comes from a configuration variable, like here: https://github.com/openstack/nova/blob/master/nova/cmd/compute.py#L71. The binary is a hard-coded string like 'nova-compute'. In the Service.cr | 19:24 |
| jaypipes | eate() method, the host is picked up by default from CONF.host configuration variable, which by default comes from a gethostname() system call from the netconf module: https://github.com/openstack/nova/blob/master/nova/service.py#L242 | 19:24 |
| bauzas | dansmith: actually, I'm even unclear myself | 19:24 |
| bauzas | dansmith: I mean, we need to draw a line for the services table saying why it's needed | 19:24 |
| jaypipes | vilobhmm1: only when the Service.start() method is called does a services database table record get created if there is none matching the host and binary: https://github.com/openstack/nova/blob/master/nova/service.py#L165 | 19:25 |
| jaypipes | vilobhmm1: after this point, the database services table records have ZERO to do with RPC communication between a consumer and a producer. | 19:25 |
| openstackgerrit | Chris St. Pierre proposed openstack/nova: Allow blacklisting os-api extensions https://review.openstack.org/160986 | 19:25 |
| dansmith | yep, that ^ | 19:25 |
| bauzas | agreed | 19:25 |
| jaypipes | vilobhmm1: the services database table is ONLY used for the crappy-ass-trying-to-be-zookeeper DB servicegroup API driver. | 19:25 |
| jaypipes | vilobhmm1: which of course you already are aware of because you submitted https://review.openstack.org/#/c/138607/ | 19:26 |
| jaypipes | vilobhmm1: and yes, I know I owe you a review on that :) | 19:26 |
| jaypipes | bauzas, dansmith: anything to add or correct to what I wrote above? | 19:27 |
| bauzas | jaypipes: MHO is that the services table should just be for referencing the services | 19:28 |
| jaypipes | say what? | 19:28 |
| bauzas | that's it | 19:28 |
| jaypipes | what do you mean? | 19:28 |
| dansmith | jaypipes: nope, I thought I was saying that already in my explanation, but not clearly I guess :) | 19:28 |
| bauzas | jaypipes: lemme rephrase the best I can | 19:28 |
| jaypipes | bauzas: that's a bit of a tautology isn't it? :) | 19:28 |
| bauzas | jaypipes: lol | 19:29 |
| vilobhmm1 | jaypipes : agree..and thanks for the reply…so in case the service/process is deleted lets say nova-compute is deleted on compute node (the rpc-server is deleted) and the entry in nova.services is marked as deleted….as you mentioned the RPC server and nova.services are not related makes sense now… | 19:29 |
| bauzas | jaypipes: not exactly, since currently the services table is more than just a reference :) | 19:29 |
| *** subscope has joined #openstack-nova | 19:29 | |
| vilobhmm1 | *nova-compute rpc-server* | 19:29 |
| jaypipes | vilobhmm1: yep, and if the nova-compute is restarted and the DB record has been deleted, then the Server.start() method will re-create the service database table record for that host. | 19:29 |
| bauzas | jaypipes: so, the best I can say is that's just mentioning that a service exists or existed | 19:30 |
| bauzas | like the Schrodinger's cat, you don't know if the service is alive | 19:30 |
| *** angdraug has joined #openstack-nova | 19:31 | |
| *** dave-mccowan has joined #openstack-nova | 19:31 | |
| jaypipes | bauzas: if you are saying that relying on the services database table for whether the service is *actually* up or down is not really possible, then yes I agree with you. :) | 19:31 |
| bauzas | jaypipes: that's MHO yes | 19:32 |
| jaypipes | bauzas: it's MHO as well :) | 19:32 |
| bauzas | hence the word "reference" | 19:32 |
| bauzas | a pointer if you prefer | 19:32 |
| vilobhmm1 | jaypipes : seems logical…thanks | 19:32 |
| jaypipes | vilobhmm1: well, it's far from logical, but hey, welcome to the servicegroup API :) | 19:33 |
| vilobhmm1 | jaypipes : haha…sure…and I agree to your point of moving the hearbeat thing or liveliness thing that the current nova.services thing is doing to something like zookeeper because of reasons mentioned in the spec https://review.openstack.org/#/c/138607/ | 19:35 |
| jaypipes | yup. | 19:35 |
| vilobhmm1 | from scheduler point of view, scheduler simply relies on nova.services to make sure if the service is up or not and not whether the service is actually running right | 19:35 |
| bauzas | vilobhmm1: that's not exactly that :) | 19:36 |
| bauzas | vilobhmm1: the scheduler just makes sure that the compute is referenced to a service, dead or notr | 19:36 |
| bauzas | not | 19:36 |
| sdague | so, wasn't the point of this that it's an eventually consistent model on the db side, less than ideal, but sometimes good enough. The zookeeper implementation was brought in to be a stronger guaruntee, at the cost of another service yuo had to run | 19:36 |
| dansmith | it's often good enough, yes | 19:37 |
| bauzas | vilobhmm1: to know if the service is up is the job of the ComputeFilter, which is optional | 19:37 |
| dansmith | which is why I don't want to condemn it any time soon | 19:37 |
| dansmith | i.e. we can't _replace_ it with zk any time soon because it's really not needed | 19:37 |
| sdague | the db implementation was there first, it was only carved into a plug point when yun and ibm research people wanted to bring in zookeeper | 19:37 |
| dansmith | but we do need to abstract it out so we _can_ reasonably replace it with things | 19:37 |
| sdague | sure | 19:38 |
| dansmith | right, and it's not really done, is the problem | 19:38 |
| sdague | well, it was half assed done :) | 19:38 |
| sdague | then rotted | 19:38 |
| vilobhmm1 | dansmith : https://blueprints.launchpad.net/nova/+spec/servicegroup-api-control-plane | 19:38 |
| dansmith | I dunno, | 19:38 |
| dansmith | maybe half-assed done is a reasonable description | 19:38 |
| vilobhmm1 | yep | 19:39 |
| sdague | also, it's probably worth figuring out if anyone is actually using the memcache driver, or if that can just be deprecated, because as far as I can tell it was just a half copy paste | 19:39 |
| dansmith | sdague: the spec calls that out pretty well I think | 19:40 |
| dansmith | dunno if you've read that or not | 19:40 |
| vilobhmm1 | sdague : https://review.openstack.org/#/c/138607/ | 19:40 |
| jaypipes | vilobhmm1: actually, the scheduler looks at the disabled state as well as the up state: https://github.com/openstack/nova/blob/master/nova/scheduler/driver.py#L54-L57 | 19:40 |
| vilobhmm1 | has clearly depicted the problem | 19:41 |
| dansmith | my point about half-assed-ness was that it seems more like quarter-ass complete :) | 19:41 |

| sdague | bauzas: no, that's fair, but I also know of other systems that started from the perfect scheduling design point | 19:47 |
| sdague | and the result is a system that had a pretty small max number of hosts | 19:47 |
| sdague | and it took 20 minutes to schedule 1 vm | 19:48 |
| dansmith | sdague: and a boot request made in 2007 is still pending | 19:48 |
| openstackgerrit | Ken'ichi Ohmichi proposed openstack/nova: Add and use raise_http_not_implemented_error() https://review.openstack.org/163697 | 19:48 |
| sdague | right, exactly | 19:48 |
| bauzas | \o/ | 19:48 |
| jaypipes | sdague: this line is the only return possible from the filter: https://github.com/openstack/nova/blob/master/nova/scheduler/filters/compute_filter.py#L50 | 19:48 |
| sdague | so... while I get that their is slop here, the slop was slightly intentional to prevent this from being a key scaling bottleneck | 19:49 |
| sdague | jaypipes: because the data model is broken? | 19:49 |
| dansmith | jaypipes: how is that? | 19:49 |
| jaypipes | sdague: because only non-disabled, non-down hosts are ever passed to the HostStateManager. | 19:49 |
| sdague | jaypipes: ok, so just that the contract was satisfied further up? | 19:49 |
| *** oomichi has joined #openstack-nova | 19:49 | |
| jaypipes | sdague, dansmith: because of this: https://github.com/openstack/nova/blob/master/nova/scheduler/driver.py#L51-L57 | 19:49 |
| *** matrohon has joined #openstack-nova | 19:50 | |
| dansmith | yeah, that changed though, yes? | 19:50 |
| jaypipes | which runs prior to the HostStateManager getting its cache of HostState objects, each of which gets its Service object from there. | 19:50 |
| openstackgerrit | Matt Riedemann proposed openstack/nova: xenapi: remove bittorrent entry point lookup code https://review.openstack.org/182048 | 19:50 |
| jaypipes | dansmith: nope. | 19:50 |
| dansmith | jaypipes: in 2012 with the servicegroup stuff | 19:50 |
| dansmith | https://github.com/openstack/nova/commit/64e167eb62bd3483b2947ec8de218453c116bd93 | 19:50 |
| *** oomichi has quit IRC | 19:50 | |
| jaypipes | dansmith: no, not really. it still does the select all non-disabled hosts from the database call. | 19:51 |
| dansmith | it did at that time? | 19:52 |
| jaypipes | dansmith: it does it via the objects API now, instead of a direct DB call, but the strategy of doing that hasn't changed. | 19:52 |
| dansmith | so it's code that never ever made sense? | 19:52 |
| jaypipes | yup. | 19:52 |
| sdague | ok, so then lets clean it up, that's cool | 19:52 |
| * harlowja lurks | 19:52 | |
| jaypipes | sdague: there's 3 blueprints proposed already for that :) | 19:52 |
| sdague | jaypipes: ok | 19:52 |
| *** jichen has quit IRC | 19:53 | |
| sdague | so this was just a vent session because everyone needed one? :) | 19:53 |
| jaypipes | sdague: sorry man, I'm not yelling at ya... :) just pointing out that a number of BPs have been created already... | 19:53 |
| jaypipes | sdague: well, no, it started as vilobhmm1 wanting answers to some questions about the services database table and its relation to the RPC communication (minimal) | 19:54 |
| sdague | sure, that's fine, what can I do to help move this ball forward? Seems like deprecating ComputeFilter should be a simple patch, given that it's functionality is duplicated at the moment | 19:54 |
| vilobhmm1 | jaypipes :exactly now uses object layer but does same db call | 19:55 |
| jaypipes | yup. | 19:55 |
| jaypipes | sdague: a review on this spec first please: https://review.openstack.org/#/c/138607/ | 19:55 |
| bauzas | sdague: http://lists.openstack.org/pipermail/openstack-dev/2015-March/058438.html | 19:56 |
| openstackgerrit | Claudiu Belu proposed openstack/nova: Hyper-V: Fixes cold migration / resize issue https://review.openstack.org/181916 | 19:56 |
| bauzas | sdague: but the scope changed since jaypipes discovered it was doubled | 19:56 |
| jaypipes | sdague: these are the other two blueprints involved: https://blueprints.launchpad.net/nova/+spec/make-availability-zone-real-data-model and https://blueprints.launchpad.net/nova/+spec/servicegroup-api-control-plane | 19:56 |

| dansmith | jogo: that force-delete patch, | 21:06 |
| dansmith | jogo: previously it allowed multiple deletes as long as you said "I really mean it for sure" in the request | 21:06 |
| dansmith | jogo: I was -1 on that because it just means everyone always force-deletes in a tight loop until their thing goes away, which is what task-state is supposed to prevent | 21:07 |
| jogo | right | 21:07 |
| jogo | dansmith: AFAIK this goes back to a patch by alaski (?) to no-op extra deletes if already in a delete state | 21:07 |
| jogo | the question is do we still want that logic or not | 21:08 |

| mriedem | that's the one | 21:11 |
| mriedem | "Dealing with delete requests that never got executed is not in scope of this change and will be submitted separately." | 21:11 |

| *** Marga_ has joined #openstack-nova | 21:18 | |

| mriedem | hard for me to see in the 'new' gerrit that i'm new to | 21:19 |
| mriedem | there is just so much gd informatoin in this style | 21:20 |
| jogo | yeah it takes some time to adjust to | 21:20 |
| jogo | mriedem: I think what this is really showing is we don't test nova enough around failure conditions in general | 21:21 |
| bauzas | mriedem: what's funny for people already using the new Gerrit UI is that the merge conflicts are at the same location than previously the series | 21:22 |
| bauzas | so I'm always wondering why patch #1 refers to patch #2 - but that just means both are conflicting :/ | 21:22 |
| * jogo slowly walks away from the mess | 21:23 | |
| mriedem | jogo: well, we test error conditions and we have negative api testing, | 21:23 |

| cfriesen | dansmith: I came across this: https://lists.gnu.org/archive/html/qemu-devel/2011-04/msg01977.html the data is a few years old, but it shows qemu+libiscsi being way faster than cache=none unless you also set aio=native | 21:50 |
| *** sdake has quit IRC | 21:50 | |
| cfriesen | dansmith: and that was for reading, not even writing | 21:50 |
| dansmith | cfriesen: I don't mean suck more == slower | 21:51 |
| dansmith | cfriesen: I just mean general correctness | 21:51 |
| *** baoli has joined #openstack-nova | 21:52 | |
| dansmith | but given how much the linux iscsi initiator stuff is used, it seems odd to me that it would be slower than the qemu one, unless it's doing safer operations, you know | 21:52 |
| cfriesen | dansmith: should be better. I just noticed an issue with udev automounting cinder volumes on the compute host. (which I think could potentially mean replaying the journal on both host and guest) | 21:52 |

| tpeoples | jaypipes: is there anything else i need to do for that? will the nova team decide to backport or not and then cherry pick it? | 21:58 |
| tpeoples | (if they decide to backport) | 21:58 |
| dansmith | cfriesen: either way, I assume you could implement this alongside what we have | 21:58 |
| dansmith | I'd have to look, but it could be interesting to provide this as an option if there really are benefits | 21:58 |
| cfriesen | dansmith: yeah, I didn't see Christoph ever addressing the fact that the testcase was read-only while the cache would only affect writing | 21:59 |
| cfriesen | dansmith: I think it'd be interesting to redo the test, at any rate. And yeah, I don't see any reason why it couldn't coexist. | 21:59 |
| dansmith | I don't really understand why this is likely to be any better than the default implementation, | 22:00 |
| dansmith | so any crazy speedup leads me to expect that there is some mismatch between configs that isn't apparent (i.e. caching issues) | 22:00 |
| cfriesen | dansmith: the main difference seemed to be the aio options...when using aio=threads it's slower | 22:00 |
| *** emagana has quit IRC | 22:00 | |
| *** annegentle has quit IRC | 22:00 | |
| dansmith | cfriesen: I mean I don't see why it'd ever be faster | 22:01 |

| cfriesen | dansmith: from http://www-01.ibm.com/support/knowledgecenter/linuxonibm/liaat/liaatbpkvmasynchio.htm: "BM® lab tests show that using AIO support can improve guest I/O performance, especially when there are multiple threads performing I/O operations at the same time. You can enable AIO by specifying aio=native in the qemu-kvm command for a KVM guest." | 22:04 |

| *** emagana has joined #openstack-nova | 22:05 | |
| cfriesen | dansmith: I'm no expert, just been looking around for info | 22:05 |
| dansmith | that means aio even for host-based devices, yes/ | 22:05 |
| dansmith | I'm no expert either, I just can't think of any *fundamental* reason why this should be faster to do it in qemu | 22:07 |
| cfriesen | dansmith: but there are other issues reported for aio=native with cache=none and sparse files, so I wasn't sure if it was okay to suggest switching to aio=native generally | 22:07 |

| *** nelsnelson has quit IRC | 22:47 | |
| dansmith | zzzeek: just want to make sure you're understanding one aspect of how nova is (usually) deployed, re: this database parallelism thing | 22:47 |
| zzzeek | dansmith: ok | 22:47 |
| *** otter768 has quit IRC | 22:47 | |
| dansmith | zzzeek: when nova-api talks to the db, it completely blocks, but we have lots of nova-api processes (real processes), so it's not *too* bad | 22:48 |
| zzzeek | dansmith: sure | 22:48 |
| dansmith | zzzeek: nova-compute does not talk to the database, but rather talks to nova-conductor, | 22:48 |
| dansmith | which also runs many (many) *processes* each of which can fall on its sword for the blocking call | 22:48 |
| zzzeek | dansmith: that is all fine, however, eventlet is still pointles within the database process | 22:48 |
| dansmith | yes | 22:49 |
| zzzeek | dansmith: the discussions are always about, threads are slow! the GIL ! terrible! | 22:49 |
| zzzeek | dansmith: which is idiotic to be honest. we have zero concurrency within a process | 22:49 |
| dansmith | your last message made it seem like maybe you thought we were even more serial than we are | 22:49 |
| dansmith | yep, okay, just making usre | 22:49 |
| zzzeek | dansmith: well fear not, robert was talking about GIL | 22:49 |
| dansmith | I know | 22:49 |
| zzzeek | dansmith: all discussions about GIL are silly. we are in the MySQLdb-Interpreter-Lock right now | 22:49 |
| *** diegows has joined #openstack-nova | 22:50 | |
| zzzeek | dansmith: i dont know if you recall, someone wanted to replace all concurrency with asyncio, because, *faster* | 22:50 |
| dansmith | they are right now, but if we were able to get to a (real) threadpool for those blocking requests, then we're contending for the GIL within a process | 22:50 |

| zzzeek | if my “we’re slow” arguemnts are tempered by “we have lots of processes”, so are all the “we can be *fast!” arguments about asyncio, if they were even true | 22:50 |
| zzzeek | dansmith: the contending for the GIL within a process when most of the work is DB work is not bad at all, and I spent a lot of time doing benchmarks to show this | 22:51 |
| zzzeek | dansmith: and it is much much less than contending for individual database conversations as we are right now | 22:51 |
| *** Sukhdev has quit IRC | 22:52 | |
| dansmith | right, I think that's what he was trying to get at, that we're good at IO-bound work, and can be threaded and not worry about th GIL if that's the case | 22:52 |
| dansmith | yes | 22:52 |
| zzzeek | dansmith: OK, I didnt exactly read it that way but I will try to see that | 22:52 |
| dansmith | I don't actually know how much CPU work we're doing processing the result of the database call | 22:52 |
| dansmith | so I don't know if we *are* cpu bound or not | 22:53 |
| zzzeek | dansmith: we’re not | 22:53 |
| dansmith | good :) | 22:53 |
| dansmith | your last point is something I'm pretty concerned about, | 22:54 |
| dansmith | although maybe in a different way than you meant | 22:54 |
| dansmith | I think the number of race conditions we manage to hit just in things like nova-compute because we're almost completely single threaded, | 22:55 |
| dansmith | has me concerned that moving straight to real threads for some of our stuff will expose a bunch of things that only work now because we didn't need to lock across a region | 22:55 |
| dansmith | which isn't a reason not to do it, but it is something that I worry about | 22:55 |
| zzzeek | dansmith: well as far as that i was alittle more handwavy, but i see the most weird bugs in things once an app goes from talking to 2 or 3 db connections at once to 30 or 40 | 22:55 |
| dansmith | yep, but I think that even not related to the db specifically, such a move would likely cause us trouble | 22:56 |
| *** BadCub is now known as BadCub-Hiding | 22:56 | |
| dansmith | more so in nova-compute than other things, and we could easily leave nova-compute async as long as conductor performs better | 22:56 |
| zzzeek | dansmith: what, just using threads? i woudl disagree with that, as long as we aren’t using shared mutable datastructures in process | 22:57 |
| zzzeek | dansmith: i think all the “Web request http” stuff should remain as async as it wants to be | 22:57 |
| zzzeek | dansmith: when you deal with HTTP connections you have to be more ready for arbitrary behavior | 22:57 |
| jaypipes | tpeoples: I tagged the bug with both juno and kilo backport potential... that should be enough :) | 22:58 |
| dansmith | zzzeek: nova-compute is *full* of mutable data structures :) | 22:58 |
| zzzeek | dansmith: that are shared between requests | 22:58 |
| zzzeek | dansmith: i haven’t seen that | 22:58 |
| *** tsekiyama has joined #openstack-nova | 22:59 | |
| dansmith | zzzeek: yeah, tons of it.. hypervisor state, resource tracker stuff, all that kinda stuff is shared common bits | 22:59 |
| dansmith | zzzeek: so if we move nova-compute to real threads, we have a ton of locking to add | 22:59 |
| zzzeek | dansmith: I’m only looking specifically at: db/sqlalchemy/api.py . that is the part that I’d put behind the thread pool | 22:59 |
| zzzeek | dansmith: basically your relational database service layer | 23:00 |
| tpeoples | jaypipes: yeah, but do i need to propose the patch to the other branches, is that done automatically, etc.? (sorry i'm fairly new to openstack) | 23:00 |
| dansmith | zzzeek: yeah, that's what I meant by keeping it collected there and leaving nova-compute async | 23:00 |
| zzzeek | dansmith: Ok then we agree :) | 23:00 |
| dansmith | zzzeek: although conductor could be fully threaded if it helped, and that would insulate us | 23:00 |
| jaypipes | tpeoples: ah, yes, you would need to do a cherry-pick to those branches. one sec, lemme grab an explanatory wiki page. | 23:00 |
| dansmith | zzzeek: but I think doing it fully at the sqalchemy/api layer is fine if it gets us everything we need | 23:01 |
| dansmith | zzzeek: so you know what has been preventing us from doing that in the past right? I'm foggy on the actual details | 23:01 |
| jaypipes | tpeoples: https://wiki.openstack.org/wiki/StableBranch | 23:01 |
| jaypipes | tpeoples: that has everything you should need :) | 23:01 |
| zzzeek | dansmith: well thats as far as I’ve been able to understand the situation, I’m not opposed to using threads more extensively but I try to always limit the territory im staking out in order to maximize the chance of success :) | 23:01 |
| tpeoples | thanks jaypipes | 23:02 |
| zzzeek | dansmith: what prevents us is, everytime it is brought up, the handwringing begins about the GIL | 23:02 |
| dansmith | zzzeek: and less code that needs to be threadsafe, yes? that seems like a good idea :) | 23:02 |
| dansmith | since we clearly suck at it | 23:02 |
| dansmith | zzzeek: no | 23:02 |
| dansmith | zzzeek: we had a way to use a threadpool for mysql stuff, but under heavy load it would stall or something | 23:02 |
| dansmith | zzzeek: I think it was related to eventlet unthreadsafeness | 23:03 |
| zzzeek | dansmith: that’s a different kind of threadpool | 23:03 |
| zzzeek | dansmith: that’s the one dug into eventlet itself | 23:03 |
| dansmith | ah, okay | 23:03 |
| zzzeek | dansmith: which yes, im sure is buggy as all get out | 23:03 |
| zzzeek | dansmith: it is too fine grained | 23:03 |
| dansmith | okay | 23:03 |
| *** emagana has quit IRC | 23:03 | |
| zzzeek | dansmith: taht’s totally where you’d see weird deadlocks happen . b.c. your DB calls are totally concurrent but your eventlet calls are forced to wait, i rememebr seeing this early on | 23:04 |
| dansmith | zzzeek: okay, makes sense | 23:04 |
| zzzeek | dansmith: they don’t mix well at that level | 23:04 |
| dansmith | zzzeek: they didn't, yeah :) | 23:04 |
| dansmith | zzzeek: so, "zzeek's awesome thread pool" + which driver? c or pymysql? | 23:04 |
| dansmith | seems like pymysql in the last email, but in previous ones, it seemed like you favored the c ones | 23:05 |
| zzzeek | dansmith: well we should probably use the new mysqliclient thing that is a fork of python-mysql | 23:05 |
| dansmith | that's the forked C one? | 23:05 |
| zzzeek | dansmith: yes. | 23:05 |
| dansmith | okay | 23:05 |
| zzzeek | dansmith: but in truth it hardly matters pymysql is very good also. mysql-python etc. will blow it away in a straight drag race style test but in real world you aren’t going to notice much | 23:06 |
| dansmith | TBH, I thought the only way we were going to get the parallelism was with the pure python one | 23:06 |
| dansmith | so if not, I'm happy and don't really care after that :) | 23:06 |
| dansmith | parallel requests, I mean | 23:07 |
| zzzeek | dansmith: i re-read my response and I know why it tweaked you, becuse im going off on “openstack is so slow!” so yes, i know things work out OK in any case | 23:08 |
| dansmith | well, | 23:08 |
| dansmith | it didn't tweak me, I just wanted to make sure you weren't doing testing with one conductor process and getting the wrong idea :) | 23:08 |

| melwitt | dansmith: I'm looking at the last of the db.instance_update calls to get rid of update_cells=True logic and I was wondering, what is the object equivalent to doing an update with a join with system_metadata? I was thinking like creating an Instance(**updates) and then saving it, but how to give sys meta as an expected_attr? https://github.com/openstack/nova/blob/master/nova/conductor/manager.py#L127-L129 | 23:13 |
| dansmith | melwitt: well, save() will save the metadata if it's set (and dirty) | 23:15 |
| dansmith | melwitt: create() should do it if it's set | 23:15 |
| dansmith | is it not? | 23:15 |
| melwitt | I could pull the instance with expected_attrs first, put the updates to it, and then save it, but I thought that's adding a db lookup | 23:15 |
| melwitt | dansmith: sorry, I didn't mean literally Instance.create because it already exists. making an Instance object. I think maybe I'm understanding now, I wouldn't need to do anything special with system_metadata like the current code is, it's only doing it for _from_db_object? | 23:18 |

| melwitt | dansmith: then I see Instance.save takes care of sending a notification update, in conductor it does notifications.send_update(context, old_ref, inst_obj, service) whereas Instance.save does notifications.send_update(context, old_ref, new_ref). if conductor needs to send "service" as part of the update, does that mean I can't replace this with Instance.save? | 23:26 |

| *** vladikr has quit IRC | 23:30 | |
| melwitt | looking... it defaults service="compute" but it looks like conductor takes a service parameter in its instance_update so it can notify with that there. I don't know much about the notifications | 23:30 |
| *** tjones1 has joined #openstack-nova | 23:30 | |
| dims | mriedem_away: i was told that visitors to the facility could ask for it when they check in | 23:30 |

| dansmith | melwitt: yeah, just found that | 23:31 |
| dansmith | melwitt: that's weird | 23:31 |
| dansmith | I must've written that | 23:31 |
| melwitt | because it's weird? :P | 23:32 |
| dansmith | oh snap! | 23:32 |
| dansmith | no, I just think I did all this stuff | 23:32 |
| *** mdbooth has joined #openstack-nova | 23:32 | |
| dansmith | so it defaults to compute on the send_update call too | 23:32 |
| melwitt | haha, okay. the statements right after each other made it sound funny | 23:32 |
| dansmith | heh | 23:33 |
| dansmith | so, | 23:33 |
| dansmith | I think you can go ahead and do this | 23:33 |
| dansmith | the only other place I see it used as other than compute is in scheduler_utils | 23:33 |
| dansmith | which should be okay I think | 23:33 |
| dansmith | I assume this is used to show in the notification what entity caused the notification | 23:34 |
| dansmith | but I assume that it's almost always "compute" regardless of where it's sent, | 23:34 |
| dansmith | since I only see it passed explicitly in scheduler | 23:34 |

| dansmith | is it? | 23:40 |
| dansmith | I don't see that | 23:41 |
| melwitt | dansmith: this? https://github.com/openstack/nova/blob/master/nova/conductor/manager.py#L604-L608 | 23:41 |
| melwitt | it looks like it's the only thing calling the scheduler utils thing | 23:42 |
| *** dims has quit IRC | 23:43 | |
| dansmith | oh, in task manager yeah | 23:43 |
| dansmith | so, anything that uses instance.save() will send "as compute" I guess, | 23:44 |
| dansmith | but that's probably already the case | 23:44 |
| dansmith | I don't think you're making it worse, | 23:44 |
