dederyvks: known issue. There's a lot of debate in the reviews around the potential fixes for this issue. You might benefit from manually applying the patches on your own (until it'll get resolved upstream, I have no idea of course which openstack release are you running and how much it's behind the upstream). Take a look at: https://bugs.launchpad.net/nova/+bug/1467581, https://bugs.launchpad.net/nova/+bug/1501735 and a09:19
openstackLaunchpad bug 1467581 in OpenStack Compute (nova) "Concurrent interface attachment corrupts info cache" [High,Fix released] - Assigned to Mark Goddard (mgoddard)09:19
dederybunch of related bugs. Anyway, once the entry is not in instance_info_caches.network_info, there's a debatable piece of code that refreshes it from Neutron (see https://review.openstack.org/#/c/230919/ which reverts it) but the side effect of it (don't know if it's important for you) is that you loose the vNIC ordering (since the only place that holds the order is instance_info_caches.network_info). I can tell you f09:19
dederyrom experience that in our case (VMs with 10-15 ports, large NFV application) it took 3 of these patches to resolve the issue (including my own https://review.openstack.org/#/c/252565). I think that sahid is better qualified to say what needs to be in and what not.09:19

dederyndipanov: hi, A. thank you for the review (https://review.openstack.org/#/c/252565). B. as you can see from the chat above (vks' observation) the disappearing vNICs/vNIC ordering/vNIC duplication is becoming more of a concern. There are a lot of attempts out there to resolve it but there's no one coherent joint effort. Maybe this is something that should be addressed in the weekly meeting?09:36

It could be just compute or all nova services. BTW for this kind of questions is better to ask in the #openstack room11:41

artomdanpb, thanks for the comments on the patches. For the record, I haven't been selectively ignoring some of your feedback, for example about XPath - what happens is I haven't figured out a away to submit only 1 from a series of multiple dependant patches. Ie, in my local repo I do git rebase -i and I have all 5 patches outstanding.13:31
*** edmondsw has joined #openstack-nova13:32
*** bkumar has joined #openstack-nova13:32
artomSo every time I submit for review, all 5 get submitted. So for example I'll change the DB patch, and use the rebase opportunity to I address the quick fixes in the others.13:33
artomPutting off the more time consuming for later.13:33

*** eliqiao_ has joined #openstack-nova13:39

sdaguebauzas: what's the question15:38
bauzassdague: see my point on https://review.openstack.org/#/c/254434/7/nova/compute/api.py sorry15:38
bauzaswe already do have a policy check in the v2.1 module but alaski has to provide the same check by the compute API since v2 doesn't do it15:38
sdaguebauzas: there are many comments there15:38
bauzasso my question is : why should we provide the policy check by the compute API module while we could add it to the v2 tree ?15:39
bauzassdague: https://review.openstack.org/#/c/254434/7/nova/compute/api.py L1413 my bad15:39
BobBallccesario: XenServer is an open source distribution of a hypervisor (xen) with commercial support options from Citrix; KVM is a hypervisor.  You'd need to compare XenServer to a KVM distribution such as RHEV to get a meaningful question - but as always, "better" is a subjective term and depends hugely on so many factors that the answer may be different for different people.  I think XenServer is better, but I know more about Xen15:40

tjonesok im on a plane so my network is slllooooowwww15:43
bauzassdague: you mean ? it's correct to provide it in the compute API module even it's also done by the v2.1 tree ? fair enough15:43
sdaguethe policy checks were left in the compute.api for v2. One could argue this is kind of gorpy.15:43
sdaguebut it's the way we are doing it across the board15:43
bauzasfor my knowledge, what's the most acceptable ? do the policy check by the API tree or by the compute API module ?15:44
alaskibauzas: note that it's just being moved from line 1087 in that file15:44
bauzasalaski: yup15:44

artommriedem, am I mistaken or do current unit tests actually *enforce* the presence of a shadow table for all tables unless explicitly specified as an exception? This is in response to your -1 on the vNIC tagging patch.16:14
*** krtaylor has joined #openstack-nova16:14
artomAnd that makes soft-delete the default, of sorts.16:14
*** fawadkhaliq has quit IRC16:14
mriedemartom: i don't think so16:14
mriedemshadow tables are only required if you have the soft-delete mixin, which right now only the tags table doesn't in the nova schema16:15
artommriedem, https://github.com/openstack/nova/blob/master/nova/tests/unit/db/test_db_api.py#L825816:15
mriedemi saw ndipanov's comment on lacking a test for enforcing that16:15
ndipanovmriedem, I don16:15

mriedemthe soft delete thing?16:17
artommriedem, https://github.com/openstack/nova/blob/master/nova/tests/unit/db/test_db_api.py#L8279 there are currently no exceptions based on that. The tags stuff is taken care of in an if earlier16:17
artomI'll add it manually I guess.16:18
artomLike tags.16:18
mriedemndipanov: re: the soft-delete thing, i have a ML thread on that because i wanted to get something documented in the devref on that policy,16:18
dansmithndipanov: but the patches only showed up two weeks before FF, so when were we supposed to provide those comments?16:18
artomBut that should really be changed in the future :) The tests, by default, are enforcing something that's no longer wantde.16:18
mriedembut the ML thread piddles out because i couldn't get a conclusion16:18
artomdansmith, well, they've been up as a monolithic WIP for a while.16:19
mriedemartom: it's fine to enforce that shadow tables are emtpy and working on tables that existed before the stance on no more soft delete16:19
ndipanovI am personally scarred by this type of behavior so feel free to diregard me as grumpy16:19
artomdansmith, my bad for leaving them as WIP I guess.16:19
mriedemmonolithic WIP for an unapproved bp doesn't get much review exposure16:19

*** pratikma_ has joined #openstack-nova16:22

artomdansmith, last question about vnic DB stuff - the spec calls for multiple tags (eventually). With a vnic_tags table there can be one entry per tag (with duplicate every except for the actual tag column). If I use the existing virtual_interfaces, what would be the correct way to store multiple tags? A JSON array as a text blob?16:41
*** pradk has joined #openstack-nova16:42
dansmithartom: how are you going to do that for bdm?16:42
dansmithartom: and what's the point of multiple tags?16:42
* dansmith looks at the spec16:42
dansmithwhat line does it say that on? I can't find it16:43
artomdansmith, I'm actually not doing in in BDM - I just have a single new 'tag' column.16:43
*** moshele has quit IRC16:43
danpbi don't think we need to care about multiple tags16:43
dansmithdanpb: agreed16:43
artomErr...16:43
artom"Although the syntax supports setting of multiple tags per device, initially the impl will only allow a single tag. The syntax just allows for future extension should there be a need."16:43
danpbwe allowed for multiple tags in the metadata schema we expose to the guest os16:43
danpbjust as a way to future proof the guest JSON format16:44
dansmithah, okay.. well, cool for future proofing, but let's not do that now16:44
dansmithyeah16:44
danpbbut i think its fine if our impl only stores a single tag in the db16:44
artomAh... So there'd be another DB migration in the future if that ever becomes implemented?16:44
*** rk4n has quit IRC16:44
*** mgoddard__ has joined #openstack-nova16:44
danpblikewise nova public API only need accept a single tag16:44
danpbartom: if that ever happens yes, but i don't really see it happening16:45
dansmithme either16:45
dansmithespecially given the api impact16:45
artomHrmm, guess I misunderstood the intent of that then.16:45

mriedemsdague: since this is already approved, you should probably call it out on the ML for nova devs to be aware of https://review.openstack.org/#/c/266492/17:29
claudiubmriedem: yeah. that mocks the wmi module.17:30
mriedemand remind everyone that they should be running -constraints jobs locally now17:30
tojuvonejaypipes: ok17:30
danpbmriedem: what does that actually mean ?17:32
danpbwhat are -constraints jobs ?!?17:32
mriedemi think it means, locally, don't run tox -r -e py2717:32
mriedemb/c that won't be gated upstream17:32
mriedemyou run tox -r -e py27-constraints17:32
mriedemfwiw, i think that project-config change was slammed in a bit fast w/o other nova cores reviewing it first17:32
danpbewww, that's a bit gross - couldn't we just rename  py27-constaints to be py27 and not make everyone remember to have to change17:33
mriedemwe could17:33
mriedemwell, except the jobs are using -constraints17:33
mriedemwe could maybe alias py27 to py27-constraints somehow17:33
danpbsigh, why did we have to rush the gate change in so fast17:34
mriedemb/c nova unit tests are broken?17:34
mriedemthere is also https://review.openstack.org/#/c/266495/17:34
mriedemclaudiub: so i take it you don't want to update the hyper-v unit tests to be more explicit about mocking out os-win rather than just globally mocking out wmi?17:35

ildikovmriedem: basically the db and obj patch itself does not do any harm19:55
mriedemsend the instance uuid you mean?19:56
ildikovthe problem is the chain which enables multiattach by the end19:56
ildikovI mean send the attachment_id to Cinder19:56
ildikovand also using instance_uuid to retrieve the BDM where possible19:56
jaypipessc68cal: what did I break this time?19:57
*** zenoway has quit IRC19:57
ildikovthe only place where it's not is the volume_snapshot_create, but that's blocked for multiattach in compute_api, therefore it's safe from upgrade perspective19:57

*** carey has quit IRC20:04
ildikovnah, that should be fine20:06
ildikovI was wondering about having an env, where not all the computes are upgraded20:07
mriedemildikov: in that case we'd detect it in the compute rpcapi and remove the attachment_id kwarg before sending it to detach_volume on the liberty level compute20:07
ildikovbut we have some, where multiattach support is added already, so there might be issues20:07
ildikovyeah, but we still have multiattached volume and sending detach to Cinder without attachment_id, which means it will not be able to identify which attachment to remove20:08
mriedemand we get a 400 then?20:09
*** aginwala has quit IRC20:12
*** lucasagomes is now known as lucas-dinner20:14
mriedemso we have a mitaka nova-api and at least one mitaka nova-compute20:14

mriedemthe mitaka nova api and compute get that request and handle it b/c they understand it20:15
*** aginwala has joined #openstack-nova20:15
mriedemthen we get a request to detach that volume and it gets to a liberty compute which won't have the attachment_id to pass on to cinder20:15
mriedemso the detach will fail on the cinder side (mitaka cinder code)20:15
mriedemildikov: is that the right scenario ^ ?20:15

ildikovmriedem: currently there's no, only unit and functional tests20:27
ildikovwe can still put an experimental flag on it20:27

*** otter768 has joined #openstack-nova20:34
mriedemi'm not sure if we have race/upgrade issues with the db one, there was concern in a previous patch set that i'm not sure is cleared up20:34

mriedemand i don't have the mixed compute scenario in my head really for where detach fails b/c we don't pass cinder the attachment id20:35
dansmithis it not a new cinder call entirely?20:35
melwittildikov, mriedem: oh, didn't realize it wasn't tied to the bp. I happened upon it in logstash flagged by an e-r check I ended up removing for an old bug and I commented on it in case it wasn't noticed yet20:35

ildikovwhen the detach goes down from the API to compute20:38
*** otter768 has quit IRC20:39
ildikovwe send the attachment_id, if the call chain is not an API detach request and we don't have it, then in cinder.py we have one more attempt to retrieve the attachment_id so Cinder knows which volume to detach20:39

ildikovthe Cinder drivers have capabilities maintained20:40
*** salv-orlando has joined #openstack-nova20:40
*** szhsong has quit IRC20:40
ildikovwhich means you cannot create a volume with multiattach support if the driver does not support it20:41

mriedemyeah, i think old cinder wouldn't be a problem20:41
*** nic1 has joined #openstack-nova20:41
dansmithbut the detach calls are passing the attachment id? is that handled in cinderclient?20:41
ildikovbecause Nova uses the multiattach flag from the volume info20:41

*** aginwala has quit IRC20:41
mriedemdansmith: yeah it's in cinderclient, at a min version that mitaka requires20:41
dansmithhmm, okay20:41
*** nic has quit IRC20:42
mriedemin the case that nova boots from volume (image/blank/snapshot) and creates the volume in cinder, we don't create it as multiattach=True20:42
ildikovI think oficially we need to support one release back20:42
mriedemFalse is the default20:42
ildikovyeah20:42
ildikovand boot from multiattach volume is disabled20:42
mriedemso in the n-1 compute case, it looks like the fallback is we get the attachments from the volume and then look for the one that is mapped to the instance uuid here https://review.openstack.org/#/c/193134/64/nova/volume/cinder.py20:42
mriedemildikov: i thought we were ok with multiattach boot from volume now? i have to go back and read the change on the amended spec20:43
*** bwallis_ has quit IRC20:43

ildikovall the other cases are fine20:43
mriedemildikov: oh right20:44
dansmithI guess you could readonly boot from multi20:44
*** jaosorior has quit IRC20:44
dansmithyou'd have to be super careful though20:44
ildikovI disabled, when destination_type is volume too20:44
mriedemso i think what i'd really like to see is a multinode test where we attach an instance on n-1 compute and current compute to the same volume, then detach both20:45
mriedemthat would this attachment_id lookup path20:45
mriedem*hit this20:45

ildikovdansmith: I was wondering to make multiattach experimental and document to enable it with homogeneous Nova env to avoid issues20:51
mtreinishmriedem: yeah, that's what I thought too20:51
dansmithildikov: the right thing to do there is to make mitaka computes able to handle it and then introduce it in newton, but .. :)20:51
ildikovdansmith: the experimental flag would do this job exactly20:52
dansmithildikov: well, we wouldn't need an experimental flag if we didn't add the feature until later20:52

mriedemand then fail if there are? so you can't multiattach in nova until all of your computes are upgrade to at least mitaka?20:58
dansmithshe said there was no new request, right? so it would just be failing the second attach in that case, right?20:59

*** rk4n has quit IRC20:59
ildikovthe bigger part of the code gets in the better for me TBH as I don't have to rebase it all the time21:00

ildikovmriedem: how the libvirt driver is upgraded?21:08
mriedemildikov: when you upgrade nova-compute21:08
ildikovI mean what's the relation between the libvirt driver and the computes?21:08
mriedem1:121:08
mriedemildikov: from what i can tell in https://review.openstack.org/#/c/193134/ you're not checking to see if the virt driver can even support multiattach21:09
mriedemfrom the capability flag i mean21:09
ildikovbut then if the compute is ok, then we're ok, if not, then it will not get into a bad situation21:09
*** krtaylor has quit IRC21:09
ildikovmriedem: yeah, don't ask me why, but I added that to the libvirt patch21:09
ildikovoh, I know why21:09
ildikovso in the second patch multiattach in block_device is not enabled at all21:10
ildikovso it's the third patch that makes the magic and that's where I added the extra check21:10
*** aysyd has quit IRC21:11
mriedemhere https://review.openstack.org/#/c/193135/74/nova/virt/block_device.py21:11
mriedemthat should probably be in the 2nd change where the capabilities flag is introduced21:11
ildikovI'm at least the third owner of this code, I rewrote 2/3 of it, but the structure more or less remained what the previous owner gave to me21:11
mriedemthe 3rd change just sets it to True for the libvirt driver21:11
mriedemyeah, you might want to add Co-Authored-By in the commit messages for this :)21:12
ildikovwithout the change in line 307 you don't have multiattach support anyway21:12
ildikovI was wondering to change author just simply21:12
*** armax has quit IRC21:13
ildikovso I can write tempest tests if I don't have to reorganize the code ;)21:13
mriedemtempest tests would live in tempest21:14

ildikovmriedem: have you just added back the libvirt version comment?21:14
mriedemyeah, why don't we have a min libvirt version check?21:14
ildikovI meant that I don't have time for both until next Thursday21:15
ildikovmriedem: check the blueprint spec amendment21:15
mriedemoh i see21:15
mriedem"You're are reading the wrong docs here. That 'shareable' flag doc you quote is the doc for the <hostdev> device type, *not* the <disk> device type. There is no min version requirement for the <shareable> flag wrt <disk> devices"21:15
ildikovyeap, so I removed it from the spec also not added to the code21:15
ildikovI was just a few tests away, when I saw that comment...21:15
mriedemok, like i said, i need to review the spec update again21:15

*** dane-fichter has quit IRC21:16
mriedemwith tempest these wouldn't be mocks21:17
*** ctrath has joined #openstack-nova21:17
mriedemthe simplest tempest test would be to just create a single multiattach volume and attach it to 2 instances21:17
mriedemtempest will need a config option so the test is conditional on whether or not the env supports multiattach (depends on which backend you're using for nova)21:18
*** MVenesio has joined #openstack-nova21:18
ildikovmriedem: could I just move to add the flag to the third patch?21:18
mriedemthe virt driver flag?21:19
ildikovmriedem: yeah, the mock comment was for the libvirt version check, I had issues there...21:19
ildikovyes, that one21:19
mriedemi think it makes more sense in the compute change, since nova.virt.block_device is really an extension of the compute layer21:19
mriedemplus that's the change that's plumbing in the api changes21:19
mriedemso say we merged that w/o the check in block_device that would cause it to fail if someone tried it, things get weird21:19
ildikovbut that change does not allow multiattach21:20
ildikovI mean the second patch21:20
ildikovso that flag is about the virt layer under compute, so I can move the flag to that change, where it belongs21:20
ildikovand then I can do all the test coverage at one place21:21
ildikovI don't get your last comment21:22
ildikovdo you mean we fail silently?21:22
mriedemso in the 2nd change a 2nd attach request for the same volume would fail b/c the volume status is already 'in-use'21:23
mriedemand block_device is checking that it's 'detached'21:23
ildikovyes21:23
mriedemi'd be ok with moving the supports_multiattach capability flag to the 3rd change21:23
*** pratikmallya has quit IRC21:23

ildikovmriedem: jaypipes: if there are as we discussed it ages ago they would, now they could write tempest tests :)21:33
doffmalaski: I'm not sure that the tradeoff is too bad. Especially as the spec talks about trimming down the tables needed in cell0.21:34
doffmalaski: Eventually the api cell would just have the tables needed for instances in error state.21:34
mriedemildikov: i might take a stab at an initial tempest change21:34
doffmrather than full duplication.21:34
dansmithdoffm: alaski: seems like the abstraction is much cleaner if we don't muddy things in the api cell too much21:35
dansmiththe special cell being otherwise a normal cell means it's actually less special and more of just a parking lot21:36
alaskiit definitely is, and that's my preference.  but I'm open to arguments21:36
*** yamahata has quit IRC21:36
alaskidoffm: it should be noted that the api db currently doesn't have the tables necessary, they would all need to be added21:36
doffmdansmith: cell0 is going to be special anyway. Its not going to be like the other cells.21:36
dansmithalaski: and we'd have some models talking to databases with both sets and some with one21:37
dansmithalaski: which means it's easier to accidentally build a relationship or dependency that we don't catch in regular cell-of-one testing21:37
dansmithdoffm: yeah I know :021:37
*** ildikov has quit IRC21:37
alaskidansmith: yeah, I totally agree21:38
doffmOk.21:39
*** ociuhandu has quit IRC21:39
dansmithalaski: an important part of this process is making sure that a single-cell deploy and a multi-cell deploy are always basically the same, and so maintaining the distinction in the single case is important21:39
doffmCell0 when finished seems like something of a rump to me, but maybe its an important one.21:40
*** thangp has quit IRC21:40
dansmithdoffm: it's a special implementation of an abstraction21:40
alaskiI'm on the side of keeping cell0 a separate thing, but I still haven't shaken the nagging feeling that asking deployers to setup a db and message queue for just a parking lot might be a bit much21:40
dansmithdoffm: as opposed to something that is special all the way up past the abstraction21:40
*** ildikov has joined #openstack-nova21:40
ildikovmriedem: sorry, my laptop has just died on me...21:41
alaskiwith cell0 there is no single cell deployment21:41

ildikovmriedem: thanks for the tempest test offering in advance21:41
dansmithalaski: eh?21:41
alaskidansmith: cell0 plus a single cell that can host instances is the minimum setup21:41
dansmithalaski: in a single cell, you've got the api db, the cell0 db and the actual cell db right?21:41
dansmithright, okay, thought you meant something else21:42
*** lpetrut has quit IRC21:42
dansmithI also feel like we'll have a LOT fewer single-cell deployments when it's trivial to add a cell21:42
dansmithwe have people with like 32 compute nodes that want to have cells21:42
alaskiit's just a slightly larger jump from 0 cells to two for the migration path21:42
dansmithalaski: what's the actual cost though? another "create database foo;" call?21:43

*** gyee has joined #openstack-nova21:44
doffmdansmith: Thats the other option. Make one cell the dump cell.21:44
dansmiththe point is just that we need a place when we can't pick a cell based on resources21:44
*** gjayavelu has joined #openstack-nova21:44
dansmithdoffm: as long as it's configurable to be a separate place, because I expect a lot of people would rather purge the dumping ground frequently21:45

alaskidoffm: the contortions to get an instance from a buildrequest is because we have to pretend we have an instance for the sake of the API21:57
dansmithrlrossit: maybe fallout21:58

auggyi have a silly openstack question, i'm trying to verify this bug - https://bugs.launchpad.net/nova/+bug/152146723:36
openstackLaunchpad bug 1521467 in OpenStack Compute (nova) "Snapshot of volume base instance shows type as image not snapshot and size as 0" [Undecided,New]23:36
auggythe reporter says they listed the images and found the type of holly-vm1-snapshot is "Image", which should be "Snapshot"23:37
auggybut the ways i know to list images don't show a type23:37
auggyor the type they show isn't snapshot or image23:37
auggynova image-list doesn't contain that field, cinder list only contains a volume-type field, and that's not technically listing images i think, and glance image-list only contains id and name23:38
auggyi am happy to ask the reporter to clarify but i didn't want to do that if there's some obvious thing i'm missing here23:39

alex_xualaski: thanks for the +223:40
alex_xudansmith: hey, I'm here now if you still wake up23:40
dansmithalex_xu: just wanted you to take another pass on those live migration patches23:41
*** armax has joined #openstack-nova23:41
alex_xudansmith: ok, I will do that today23:41
dansmithalex_xu: I just added those two attributes to the object and  converted the post path23:41
dansmithalex_xu: we had some random gate failures today, let me see about rechecking them23:41
alex_xudansmith: cool :)23:41
*** logan2 has joined #openstack-nova23:42
alex_xudansmith: I have question about libvirtmigrationdata obj.23:42
mtreinishauggy: I would assume that bug is referring to cinder volume type since it's talking about boot from volume which should be doing cinder snapshots iirc23:42
dansmithalex_xu: okay23:42
*** logan2 is now known as logan-23:42
auggymtreinish: yeah it was just confusing because the repro steps specifically said list the images? idk, i just marked as incomplete since they'd mentioned an attachment with a screenshot and it's missing23:42
alex_xudansmith: this patch https://review.openstack.org/254101 want to change the block_migration field's nullable. I guess we can't change that directly, right?23:42
dansmithalex_xu: yeah, because if we have null for those values we can't send them to older clients23:43
* auggy has a little tech support experience lol23:43
dansmithalex_xu: so that would break talking to those older clients (i.e. live migrations between those two)23:44

*** szhsong has quit IRC23:44
alex_xudansmith: but for now, your patch https://review.openstack.org/251588 didn't merge yet, do we have chance change that easily for now? or just create another field?23:44
auggymtreinish: i volunteered for bug skimming duty which technically doesn't start until thursday but i figured i'd get a head start ;)23:44
*** akshai has quit IRC23:44
*** szhsong has joined #openstack-nova23:45
dansmithalex_xu: well, we probably could because we don't send it over the wire yet, BUT, the proper way is not to pass None there, but to leave those unset I think23:45
*** armax has joined #openstack-nova23:45
dansmithalex_xu: being unset and calculated is better than always passing None from here on out23:45
dansmithalex_xu: leaving them unset also lets us deprecate and remove those two fields later much easier23:45
*** gangil has quit IRC23:46
mtreinishauggy: there is a metadef thing in glance which maps resources associated with an image, but as far as I know there isn't an image "type" (besides the disk format etc, which doesn't sound related)23:46
*** gangil has joined #openstack-nova23:46
*** gangil has joined #openstack-nova23:46
dansmithalex_xu: so instead of him doing "if md.block_migration == None" he should do "if 'block_migration' not in md"23:46

dansmithalex_xu: I can comment23:46
