| alex_xu | johnthetubaguy: is that old behaviour? as my understand, the API always return 500 with invalid regex, so it should be never works in the before | 09:59 |
| alex_xu | let me check the bug report, whether I missed something | 10:00 |
| johnthetubaguy | alex_xu: what I mean is, the current behaviour is better than the old 500 | 10:00 |
| johnthetubaguy | alex_xu: its just odd from a user perspective | 10:00 |
| alex_xu | johnthetubaguy: ah, yea | 10:00 |
| johnthetubaguy | alex_xu: they have a list of servers, they are using filtering by name to show some server details, but some of the queries return 400 (or 500) instead of the server | 10:01 |
| *** yuntongjin has quit IRC | 10:02 | |
| johnthetubaguy | defaulting to exact match when it was an invalid regex seemed quite nice, although I guess its hard to debug your regex that way | 10:02 |
| alex_xu | johnthetubaguy: yea, and that sounds like API behaviour change, doesn't sounds like we can change API without microversion | 10:03 |
| johnthetubaguy | if it were 500 -> results like when this was first proposed, it wouldn't be, which is the odd thing I guess | 10:04 |
| johnthetubaguy | if it were name_regex= I wouldn't worry about this either I guess | 10:05 |
| bauzas | lyarwood: AFAIR, nova unittests can run behind a mysql driver backend instead of sqlite | 10:06 |
| bauzas | given the Database fixture does use the default oslo.db values for creating the DB | 10:06 |
| mdbooth_ | bauzas: I did some work on this a couple of years ago and there were a few wrinkles but mostly it just worked | 10:07 |
| mdbooth_ | For unit tests, that is | 10:07 |
| bauzas | for functional tests, we need to make sure it does use the same path | 10:07 |
| lyarwood | bauzas: yeah I think you need to actually configure mysql/mariadb to use the default creds for it to work right? | 10:07 |
| bauzas | yeah | 10:07 |
| mdbooth_ | IIRC, the biggest wrinkle at the time was that sqlite (used by default) allowed millisecond accuracy in timestamps, whereas mysql only does 1 second | 10:07 |
| mdbooth_ | This broke a bunch of unit tests which wrote non-rounded seconds into the db and expected to read the same value back. | 10:08 |
| bauzas | here, I suppose lyarwood wanna test some very specific ones | 10:08 |
| *** mdbooth_ is now known as mdbooth | 10:08 | |
| bauzas | not running the whole job | 10:08 |
| lyarwood | bauzas: well downstream we hit a func test failure caused by the sqlite version we are shipping in RHEL | 10:09 |
| alex_xu | johnthetubaguy: yes, agree that is odd | 10:09 |
| mdbooth | Although running the whole job isn't a bad idea. There are a bunch of very interesting semantic differences. | 10:09 |
| lyarwood | bauzas: as we don't support sqlite we need to switch these jobs over to mariadb | 10:09 |
| alex_xu | johnthetubaguy: just check the history, we fix the 500 at https://review.openstack.org/#/c/344945/ | 10:09 |
| bauzas | lyarwood: yeah I heard that from migi | 10:09 |
| johnthetubaguy | alex_xu: yeah, I remember worrying about that bug fix we had pending when approving that one | 10:09 |
| *** karimb has joined #openstack-nova | 10:10 | |
| bauzas | lyarwood: so you would run a specific functional tests job backed by mariadb, right? | 10:10 |
| bauzas | not all the UTs ? | 10:10 |
| lyarwood | bauzas: well, all of the func tests that we can using mariadb | 10:11 |
| lyarwood | bauzas: and any UTs that are using the DB as well tbh | 10:12 |
| bauzas | okay, so fixing upstream the wrinkles that mdbooth said would then a good idea | 10:12 |
| bauzas | at least, the first step is to configure the jobs and see what are the results | 10:12 |
| bauzas | I'd only consider functional tests at a first step tho | 10:13 |
| alex_xu | johnthetubaguy: so probably we can introduce "/servers?name=in:VM1,VM2" in the future | 10:13 |
| alex_xu | for the exact match | 10:13 |
| bauzas | alex_xu: I had a patch up for the in: tag a while ago | 10:13 |
| alex_xu | bauzas: yea, I learned from that | 10:13 |
| johnthetubaguy | alex_xu: oh... the in operator, thats a good way around that one | 10:14 |
| bauzas | alex_xu: disclaimar, I haven't read the above discussion, so no context here yet | 10:14 |
| bauzas | disclaimer* even | 10:14 |
| johnthetubaguy | alex_xu: so I -2ed that patch, I can catch up with sneti on why I did that later on | 10:14 |
| *** moshele has quit IRC | 10:15 | |
| *** moshele has joined #openstack-nova | 10:15 | |
| alex_xu | johnthetubaguy: ok, if sneti happy with that, we better to have a patch to tell the user how to match exact name in the current API behaviour | 10:15 |
| alex_xu | in api-ref | 10:15 |
| johnthetubaguy | alex_xu: yeah, I can't remember what we say in there right now | 10:16 |
| johnthetubaguy | "Filters the response by a server name, as a string. You can use regular expressions in the query. For example, the ?name=bob regular expression returns both bob and bobb. If you must match on only bob, you can use a regular expression that matches the syntax of the underlying database server that is implemented for Compute, such as MySQL or PostgreSQL." | 10:16 |
| johnthetubaguy | thats probably OK | 10:16 |
| alex_xu | oops, that depend on the underlying database, that is bad :( | 10:17 |
| alex_xu | and we validate the regex with python first...https://github.com/openstack/nova/blob/master/nova/api/validation/validators.py#L40 | 10:20 |

| *** david-lyle has quit IRC | 17:24 | |
| sdague | mriedem: well, that's the question | 17:24 |
| mriedem | so, ibm pulled out from translating log messages and now they just don't care, | 17:25 |
| mriedem | from what i remember, i18n of the non-debug log messages was a product priority for ibm several years ago, | 17:25 |
| dansmith | yep | 17:26 |
| mriedem | i.e. ibm products based on openstack required log translation | 17:26 |
| mriedem | so rather than do all of that in-house, we pushed and pushed those teams to upstream the translation work | 17:26 |
| mriedem | now i guess they have dropped out | 17:26 |
| mriedem | so no one cares anymore | 17:26 |
| dansmith | so wait, just to be clear.. 1. PowerVM 1.0, 2. DB@, 3. Log translation.. do I have that right? :) | 17:26 |
| dansmith | heh, DB2 I mean | 17:26 |
| mriedem | i think most ibm products would also have specific codes for errors/warnings/info in user-facing or translated messages | 17:27 |
| mriedem | so the problem of identifying an error on the internet just involves the code | 17:27 |

| *** owalsh has joined #openstack-nova | 18:17 | |

| johnthetubaguy | https://etherpad.openstack.org/p/MIL-ops-meetup | 18:18 |
| johnthetubaguy | has the extra info | 18:18 |
| dansmith | okay but what sort of help? | 18:19 |
| mriedem | is someone moderating that session? | 18:19 |
| mriedem | on cells v2? | 18:19 |
| mriedem | 3/16 at 9:40am | 18:19 |
| dansmith | italy time? | 18:19 |
| mriedem | i reckon | 18:19 |

| *** lucasagomes is now known as lucas-afk | 18:20 | |
| mriedem | i'll ask in operators | 18:20 |
| *** gaoyuan has quit IRC | 18:20 | |
| johnthetubaguy | I offered to try and remote in somehow, should there be no other option for Nova representation | 18:20 |
| johnthetubaguy | mriedem: there is a live-migration one as well | 18:21 |
| johnthetubaguy | one of the OSIC folks testing it was going to moderate that one | 18:21 |
| mriedem | no one has reached out for help from the nova team on this, at least not me | 18:22 |
| mriedem | so i don't know what level of coordination is expected for the ops meetup | 18:22 |
| mriedem | or if it's ops people self-moderating | 18:22 |
| mriedem | but i thought the forum was where the nova team talks about the new fancy stuff to the ops people | 18:22 |
| mriedem | i assume a live migration session at the ops meetup is about info sharing | 18:22 |
| mriedem | best practices, etc | 18:23 |
| johnthetubaguy | mriedem: yeah, I thought that too | 18:23 |
| mriedem | and i doubt anyone there will be new enough to have cells v2 | 18:23 |
| johnthetubaguy | we have previously had Nova folks at most of the ops summits, but a little bit by chance, I did the manchester one, for example | 18:23 |
| mriedem | and sdague was in NY | 18:24 |
| johnthetubaguy | mriedem: yeah I assumed that too, not sure why | 18:24 |
| mriedem | and melwitt i think | 18:24 |
| mriedem | well this is kind of last minute | 18:24 |
| johnthetubaguy | yeah | 18:24 |
| mriedem | cells v2 is going to be presented at the summit, | 18:24 |
| mriedem | dansmith has a talk for it specifically, and i will be bringing it up in my talk about the new and notable in ocata | 18:24 |
| johnthetubaguy | yeah, I think thats the right way to get that info | 18:24 |
| johnthetubaguy | I duno what they want from the cells v2 session | 18:25 |
| mriedem | i'm ignoring the fact that some operators are probably not going to be going to the summit b/c they traded for the ops meetup or PTG | 18:25 |

| jgriffith | mriedem thanks for raising it | 18:45 |
| mriedem | https://review.openstack.org/#/c/91321/ was also an old spec, | 18:45 |

| *** maciejjozefczyk has quit IRC | 18:45 | |
| jgriffith | mriedem best kind of spec is the spec with no details | 18:45 |

| mriedem | logan-: ok, cfriesen and the windriver team have something similar i'm told, and we talked about it at the ptg so figured it was his team pushing that up | 19:41 |

| *** lucasxu has joined #openstack-nova | 21:06 | |
| jgriffith | soon they won't invite me at all :) | 21:06 |
| alexandrelevine | So there is a problem with the ScaleIO ephemeral driver. And it's mostly historical and resource-wise. I'll explain. | 21:06 |
| jgriffith | alexandrelevine sure | 21:07 |
| *** lucasagomes has joined #openstack-nova | 21:07 | |
| alexandrelevine | We started doing it 1.5 years ago when we worked for EMC. And we were postponed because at the time a refactoring started in the same area - imagebackend.py | 21:07 |
| alexandrelevine | We were told that it'll go fast and well but as often it didn't. So we were postponed once. And then twice because of communicational and organizational reasons. | 21:08 |
| alexandrelevine | And now seems to be the third time. | 21:08 |
| alexandrelevine | All this time we had to support patches for new versions of nova and ScaleIO aside from the main code. | 21:08 |
| *** lpetrut has quit IRC | 21:08 | |
| jgriffith | alexandrelevine so to be clear I have the luxury of being able to claim "not being involved" in any past efforts :) | 21:08 |
| alexandrelevine | Now we've left EMC and we don't have enough resources to keep doing this cumbersome tasks. | 21:08 |
| jgriffith | so while I feel for ya, I don't necessarily have anything to say about that | 21:09 |
| jgriffith | alexandrelevine Ahh! | 21:09 |
| *** Apoorva has quit IRC | 21:09 | |
| jgriffith | Well so you just made a case for my number one argument :) | 21:09 |

| jgriffith | alexandrelevine but you won't be able to support it fully? (ie your comment about resources) | 21:10 |
| alexandrelevine | But to start all over again and to do the cinder backend might not be in our power at the moment. | 21:10 |
| alexandrelevine | We would be able to support fully the ScaleIO code we created. | 21:10 |
| alexandrelevine | But we don't have resources to start over from another angle. | 21:11 |
| alexandrelevine | Also as I said we know the area quite well - I did a POC for the total refactoring as well. | 21:11 |
| alexandrelevine | So there some tricky parts and design problems. | 21:11 |
| mriedem | alexandrelevine: can you explain the issues that you think will be a major issue for the generic cinder driver? | 21:11 |
| alexandrelevine | And the code to work with is far from the ideal state. | 21:11 |
| alexandrelevine | The same as for other ephemeral drivers. Namely: | 21:12 |
| alexandrelevine | 1. Entangled code to introduce changes into. | 21:12 |
| alexandrelevine | 2. Tricky operations like live migration and resizing, pieces of which are evenly spread around two files. | 21:12 |
| alexandrelevine | 3. Specifics of behavior like 8-gb granular disk allocations for ScaleIO. | 21:13 |
| openstackgerrit | Ed Leafe proposed openstack/nova-specs master: The ResourceProviderTraits API - Manage traits with ResourceProviders https://review.openstack.org/345138 | 21:13 |
| alexandrelevine | 4. Specifics of implementation like necessity to map/unmap ScaleIO volumes to host unlike for ceph | 21:13 |
| alexandrelevine | And such... | 21:13 |
| *** pcaruana has quit IRC | 21:13 | |
| jgriffith | alexandrelevine but the Cinder approach would require handling all of those for ALL backends no? | 21:14 |
| mriedem | how do 3 and 4 not get handled by cinder and os-brick? | 21:14 |
| jgriffith | with the exception of #3 | 21:14 |
| *** gsxr has joined #openstack-nova | 21:14 | |
| alexandrelevine | It would take some design decisions, communications between interested parties, talks, reviews, etc. With the usual round-trips for all of this, realistically, it's 2-3 releases at the best. Of course if it was all in one organization it could've be done in month or two. But that's not the case. | 21:14 |
| mriedem | for #2, wouldn't live migration and resize work the same as for boot from volume? | 21:14 |
| alexandrelevine | jgriffith: Abouth the #4. I'm not sure. It might. But most probably it won't. | 21:15 |
| jgriffith | alexandrelevine well I don't think that's necessarily true, I certainly hope not | 21:16 |
| jgriffith | I'm honestly hoping that this is something that we can somehow pull of in this cycle | 21:16 |
| -openstackstatus- NOTICE: restarting gerrit to address performance problems | 21:16 | |
| jgriffith | otherwise I'll go back to pushing my flavor-extra-specs proposal and forget all of it :) | 21:16 |
| jgriffith | alexandrelevine so seriously... | 21:16 |
| jgriffith | alexandrelevine I get where you're coming from and I understand you've already invested a lot perhaps | 21:16 |
| jgriffith | BUT | 21:16 |
| alexandrelevine | jgriffith: There is a number of different disk types in nova - local/root/config/volume - some of which are intermingled with other. So I'm not sure that mapping/unmapping would be enough to be done outside. Probably but not necessarily | 21:17 |
| *** rmart04 has quit IRC | 21:17 | |
| jgriffith | I think it's fundamentally WRONG to continue doing all these one offs for just one particular vendors interests | 21:17 |
| jgriffith | especially if/when we all have a common interest in achieving the same thing | 21:17 |
| *** huanxie has quit IRC | 21:17 | |
| jgriffith | why not utilize your resources and efforts to better the entire project and not just your product? | 21:17 |
| alexandrelevine | jgriffith: They honestly hoped that they'd pull the refactoring in 1 month. It still goes. And that's exactly same area with the same problems. | 21:17 |
| mriedem | alexandrelevine: i don't remember anyone claiming the entire imagebackend refactor what mdbooth was doing in newton would be done in a month | 21:19 |
| alexandrelevine | jgriffith: Our stuff is already done and ready. New thing - is a significantly much more work for us. | 21:19 |
| jgriffith | I've had the same debates in Cinder WRT other things EMC has proposed (VIPER, CPRHD...) so while I sympathize I can say that you're very unlikely to change my opinion on this | 21:19 |
| alexandrelevine | mriedem: I remember | 21:19 |
| jgriffith | others have tried for years :) | 21:19 |
| *** yamahata has quit IRC | 21:19 | |
| *** owalsh_ is now known as owalsh | 21:19 | |
| alexandrelevine | mriedem: We were told that it'll be done by June and then we'll add our code. | 21:19 |
| mriedem | anyway, that effort derailed and we talked about it in BCN, and it's not being worked now i don't think, | 21:20 |
| alexandrelevine | jgriffith: At the moment people which added ploop as I know proceed with changing the code. I'd suggest to let ScaleIO in along with starting the work on cinder backend. This way people would get the only really competing to ceph storage backend soon. Otherwise - time is indefinite. | 21:21 |
| jgriffith | alexandrelevine lucky for you I carry no weight on the Nova team, but honestly I think it'd be irresponsible to move forward with a one-off solution as opposed to workign on a generalized approach | 21:21 |
| mriedem | and what i'm hearing is, adding a generic cinder driver is going to be hard because the code is a hot mess, and because the scaleio work has been going on for over a year, you've dealt with that mess | 21:21 |
| alexandrelevine | mriedem: Yes. And as I said I dealt even more with that mess when I proposed the POC for that same refactoring so I think I correctly estimate the picture. | 21:21 |
| mriedem | so rather than start over on the hard thing that everyone wants, add another special backend and all of the conditionals that go along with in the libvirt driver code | 21:22 |
| sdague | cburgess: just for you - http://docs-draft.openstack.org/03/441203/8/check/gate-keystone-specs-docs-ubuntu-xenial/923ac60//doc/build/html/specs/keystone/backlog/hierarchical-quota-scenarios.html#make-chet-sad-model | 21:22 |
| *** crushil has joined #openstack-nova | 21:22 | |
| mriedem | alexandrelevine: i also don't really see what motivation your team has for maintaining this once it's in tree unless you're getting paid to maintain it | 21:22 |
| alexandrelevine | mriedem: Me neither. But we're doing it right now. Maybe we just don't like to drop what we're responsible for. | 21:23 |
| alexandrelevine | mriedem: And part-time participation is not such a big load on us comparing to, say, a full month work. | 21:23 |
| mriedem | alexandrelevine: i can see that, i worked on getting db2 support into nova for 2 years, and then we ripped it out about 6 months later because ibm stopped supporting it upstream | 21:23 |
| mriedem | however, i'm not trying to get db2 back into nova | 21:24 |
| alexandrelevine | mriedem: Don't mind if we rip ScaleIO out in favor of ready cinder backend even a week after. It just has to work. | 21:24 |
| jgriffith | alexandrelevine honestly I would've thought based on your statements you'd prefer the general cinder driver approach. | 21:24 |
| mriedem | alexandrelevine: removing things is harder than just adding them in and letting them rot | 21:24 |
| *** hoangcx has joined #openstack-nova | 21:25 | |
| alexandrelevine | mriedem: I just fill sort of responsible for the unfinished solution and we don't have much resources to keep patching it aside - it's even more work. | 21:25 |
| jgriffith | alexandrelevine you already stated you don't have resources to work on / maintain the effort | 21:25 |
| mriedem | jgriffith: i'm sure they do, but they don't favor the investment in doing the new thing, or waiting for it | 21:25 |
| jgriffith | alexandrelevine you know as well as anybody that this code isn't static | 21:25 |
| mriedem | alexandrelevine: if EMC cares about it, then xing-yang's team would own rebasing it shouldn't they? | 21:25 |
| jgriffith | mriedem ahh... well; I don't favor this option either, but I'm willing to try it to do something that better satisfies everyone involved | 21:26 |
| alexandrelevine | jgriffith: Architecturally - absolutely. We even discussed when we designed the solution. But knowing the problems we decided to go for smaller, more safe thing. Thinking that it'll be much less time, especially after verbal confirmations. | 21:26 |
| mriedem | jgriffith: which option? add the scaleio driver in until the generic driver shows up and then remove the scaleio driver? | 21:26 |
| alexandrelevine | mriedem: exactly | 21:26 |
| jgriffith | mriedem flavor :). Just ignore that | 21:26 |
| alexandrelevine | mriedem: They don't have sufficient expertise to start new thing at the moment but to help support ours - it's possible. | 21:27 |
| mriedem | but again, you no longer work for EMC and while it's nice you say you'd support it anyway, i don't see that happening in 6 months just from a purely motivational aspect, which is why i'd think that if EMC cares about this they'd have people backfilling your team to support this | 21:28 |
| jgriffith | alexandrelevine wait... you're saying Xing's team doesn't have the expertise? I'd argue strongly against that statement | 21:29 |
| alexandrelevine | jgriffith: By the way - this code is quite static, by the way :) Any attempts in refactoring have failed as I understand. | 21:29 |
| alexandrelevine | mriedem: They do. | 21:29 |
| jgriffith | alexandrelevine here's the thing... I want this feature as per customer requests for SolidFire | 21:30 |
| alexandrelevine | mriedem: They care about this direction. But I said that we'll finish because any new guys would take time to get into the code and the nova procedures and processes so again 2-3 more releases at the best. | 21:30 |
| jgriffith | alexandrelevine so if you go this route, then that means I go this route... then Pure does the same, then <insert-1-of-100-cinder-backends-here> go this route | 21:30 |
| jgriffith | that's stupid | 21:30 |
| jgriffith | Sure, it'd be easier for me to do it this way too, but that doesn't mean it's a good idea | 21:31 |
| alexandrelevine | jgriffith: You can call it stupid, but that's reality. | 21:31 |
| alexandrelevine | jgriffith: I wouldn't recommend to go the same way again now that everybody is pro universal backend. | 21:31 |
| jgriffith | alexandrelevine wait.. to be clear, I'm saying if we had 100 backends image drivers in Nova that would be stupid | 21:31 |
| jgriffith | not what you're doing is stupid | 21:31 |
| alexandrelevine | jgriffith: I'd suggested to start with it. It's about the same amount of work. No need to create SolidFire specific piece. | 21:32 |
| jgriffith | LOL | 21:32 |
| alexandrelevine | :) | 21:32 |
| jgriffith | so it's no good for you, but good for everyone else :) | 21:32 |
| mriedem | to be clear, i'm not going to support 100 cinder drivers in nova | 21:32 |
| jgriffith | mriedem no? Damn! | 21:32 |
| mriedem | which is why we want to stop doing this | 21:32 |
| jgriffith | mriedem +1 | 21:32 |
| *** baoli has joined #openstack-nova | 21:33 | |
| jgriffith | mriedem and that's why I never even bothered trying to go down that path | 21:33 |
| mriedem | because i'm sure veritas is wanting the same thing | 21:33 |
| mriedem | veritas has been pushing specs for the same stuff | 21:33 |
| alexandrelevine | Guys I totally agree with stopping doing it. I'm just saying that if you stop BEFORE Scaleio is in it means that it'll be out for 2-3 more releases. | 21:33 |
| alexandrelevine | I tell you what. We can even consider doing or helping doing the cinder driver in nova. | 21:34 |
| alexandrelevine | Because it's interesting and we're quite into it. | 21:34 |
| *** Jeffrey4l has quit IRC | 21:35 | |
| alexandrelevine | But not as a replacement for now-ready ScaleIO. In more relaxed schedule and if Randy approves because we still work with him. | 21:35 |

| *** aysyd has quit IRC | 21:37 | |
| jgriffith | alexandrelevine ok, so look from my perspective; it's the wrong direction. | 21:38 |
| jgriffith | alexandrelevine I feel for ya in terms of investment etc but my vote is generalized solution | 21:38 |
| jgriffith | alexandrelevine I'm sorry about that | 21:38 |
| mriedem | alexandrelevine: jgriffith: i was mostly looking for input on the specific issues that are going to delay the cinder backend, | 21:38 |
| alexandrelevine | jgriffith: generalized solution with "no" for the specific one for now? | 21:38 |
| mriedem | alexandrelevine: i'm not asking your team to write that code, | 21:39 |
| jgriffith | but it's the right thing to do in terms of the overall project and it's the "fair" thing to do in terms of vendors and MOST OF ALL it's the right thing to do in terms of cloud deployers | 21:39 |
| jgriffith | alexandrelevine correct, no specific drivers | 21:39 |
| mriedem | but we obviously need to start with a spec and detailing the issues that are going to be hit with this will help give a better idea of how long and risky that's going to be | 21:39 |
| jgriffith | alexandrelevine I sincerely would hope you and your team would help in the effort given you have vast experience and interest | 21:39 |
| alexandrelevine | mriedem: You did that with imagebackend refactoring. Did it help you to predict 1.5 years and failure in the end? | 21:40 |
| jgriffith | but if you can't/don't then that's ok too; doesn't change my opinion | 21:40 |
| alexandrelevine | mriedem: What if you spend 2 months on the spec and find it risky and difficult or just difficult and taking 2-3 more releases? | 21:40 |
| mriedem | i don't have enough info to make a judgement call on whether or not we should take on the technical debt for the backend that may or may not be supported, unless i have a better understanding of how hard it's going to be to get the cinder driver done | 21:40 |
| alexandrelevine | mriedem: What I'm saying is that the question is - when did you get clear and correct specs of that complexity in this area? I'm again referring to the refactoring spec/specs. | 21:42 |
| alexandrelevine | Ours is good because we have the code which works for 1.5 year already. | 21:42 |
| alexandrelevine | mriedem: Who'll right such a spec? Who has a thorough enough expertise? | 21:42 |
| mriedem | alexandrelevine: the imagebackend refactor failed for different reasons | 21:43 |
| alexandrelevine | "write" | 21:43 |

| mriedem | ildikov: i am | 22:52 |
| ildikov | mriedem: tnx | 22:52 |
| ildikov | mriedem: so I always confuse myself with the release notes | 22:52 |
| ildikov | mriedem: I'm cleaning up the patch to move Nova to Cinder v3, the base 3.0 | 22:53 |
| ildikov | mriedem: and was wondering whether it's 'other' or 'upgrade' category? | 22:53 |
| mriedem | ildikov: depends on the change | 22:54 |
| ildikov | mriedem: and how much we want to go into if anyone wants v2 as they might have a that old Cinder but they love it they can modify the 'catalog_info' in the config? | 22:54 |
| mriedem | supporting cinder v3 would probably be a feature | 22:54 |
| mriedem | are you also changing the default? | 22:54 |
| *** JoseMello has quit IRC | 22:55 | |
| mriedem | changing the default on a config option means a reno in the upgrade section | 22:55 |
| ildikov | mriedem: if changing the default equals to set the catalog_info to v3, then I'm changing the default | 22:55 |
| mriedem | yeah | 22:55 |
| mriedem | so upgrade section | 22:55 |
| ildikov | mriedem: as we agreed to change the default in case I need to do more than that please point me to that too :) | 22:56 |

| tonygunk | Wondering if someone can point me in the right direction in error I'm getting with Ocata and Xen Hypervisor | 23:14 |
| tonygunk | http://paste.openstack.org/raw/601670/ | 23:15 |
| tonygunk | Getting the following: TypeError: Argument must be bytes or unicode, got 'NoneType' | 23:15 |
| tonygunk | All other hypervisors are running KVM and no issues of course - just trying Xen on one node | 23:17 |

| mriedem | tonygunk: libvirt + xen or xenapi? | 23:23 |
| mriedem | because this looks like it's hitting libvirt code | 23:23 |
| tonygunk | libvirt + xen | 23:23 |

| mriedem | tonygunk: gotta be something wrong down this path https://github.com/openstack/nova/blob/15.0.0/nova/virt/libvirt/driver.py#L4415 | 23:28 |
| mriedem | https://github.com/openstack/nova/blob/15.0.0/nova/virt/libvirt/driver.py#L4435 | 23:29 |
| mriedem | https://github.com/openstack/nova/blob/15.0.0/nova/virt/libvirt/driver.py#L4489 | 23:29 |
| mriedem | log_path would be None there | 23:29 |
| mriedem | for xen | 23:29 |
| mriedem | tonygunk: do you have these minimum versions for libvirt/qemu? https://github.com/openstack/nova/blob/15.0.0/nova/virt/libvirt/driver.py#L275 | 23:30 |
| mriedem | looks like the libvirt+xen CI running against nova is testing against an older libvirt | 23:32 |
| mriedem | 1.3.1 | 23:32 |
| mriedem | so that CI wouldn't have caught this | 23:32 |
| mriedem | but yeah that's the bug | 23:33 |
| mriedem | tonygunk: looks like you could set [serial_console]/enabled=True in nova.conf to workaround this for now | 23:33 |

| tonygunk | mriedem: I just tried the workaround and it works | 23:37 |
| tonygunk | mriedem: I sincerely appreciate you looking at this. My python fu is not equivalent | 23:38 |
