| chenfan | hi all, I am new to openstack, there is a question I want to know, when I used pdb to debug the nova list command in libvirt driver, e.g. I set a set_trace() in function list_instances, then call the `nova list` to list the domains, I expect I can see the all trace, but the nova list return me an instances list, and do not involve the breakpoint, | 02:28 |
| chenfan | but after a while, the breakpoint stopped. then my question is the async list call is right? because `nova list` don't show the list got from libvirtd directly. so maybe there is a gap between client and servers about the guest status sync, maybe nova list just show a cached list right? | 02:28 |

| chenfan | <eliqiao>: thanks, I just think the client maybe return a old status for VM, but virtually, the VM status has been changed in libvirt, is it ok for guest? | 02:34 |
| chenfan | or client? | 02:34 |

| johnthetubaguy | sfinucan: I should be able to give some context | 08:55 |
| johnthetubaguy | sfinucan: part of it is locking, to stop two competing actions on the same VM | 08:56 |
| johnthetubaguy | sfinucan: part of it is to tell users what state their VM is in | 08:56 |
| *** gmann_ has joined #openstack-nova | 08:56 | |
| johnthetubaguy | sfinucan: originally it was the only way to report the progress of an asynchronous action | 08:56 |

| *** sree_ has joined #openstack-nova | 08:57 | |
| *** flwang has joined #openstack-nova | 08:57 | |
| johnthetubaguy | if I remember correctly, task_state was originally for reporting sub-sets of the larger action | 08:57 |
| *** sree_ is now known as Guest40721 | 08:57 | |
| *** efoley has joined #openstack-nova | 08:57 | |
| johnthetubaguy | sfinucan: there is also power_state, which is semi-independent of those | 08:57 |
| sfinucan | johnthetubaguy: So many states... | 08:58 |
| sfinucan | johnthetubaguy: So I do get the task_state vs. vm_state thing | 08:58 |
| johnthetubaguy | sfinucan: did you see this? http://docs.openstack.org/developer/nova/vmstates.html | 08:58 |
| sfinucan | johnthetubaguy: I didn't, and that's perfect for my question | 08:59 |
| johnthetubaguy | sfinucan; not sure its up to date, but it looks close | 08:59 |
| *** efoley_ has joined #openstack-nova | 08:59 | |
| johnthetubaguy | sfinucan: hmm, its missing some of the RESIZED sub-states looking at it, like confirm/verify, etc | 08:59 |
| johnthetubaguy | oh, maybe those are task states, oh well | 09:00 |
| *** sree has quit IRC | 09:00 | |
| mdbooth | They all need to be enums/state machines really | 09:00 |
| sfinucan | johnthetubaguy: Yeah, I think they're task states | 09:00 |
| sfinucan | See here | 09:00 |
| sfinucan | #link https://wiki.openstack.org/wiki/VMState | 09:00 |

| sfinucan | johnthetubaguy: I think I figured out the issue with the Intel NFV CI (it's failing on shelve/unshelve w/ special flavors, see mailing list) | 09:02 |

| *** efoley has quit IRC | 09:03 | |
| gibi | johnthetubaguy: hi! Could you check this requirement pin? https://review.openstack.org/#/c/322544/ this is needed to unblock the gate due to https://bugs.launchpad.net/nova/+bug/1586976 | 09:03 |
| openstack | Launchpad bug 1586976 in OpenStack Compute (nova) "Nova UTs and functional tests broken due to cinderclient modifying i18n global vars" [Critical,Confirmed] - Assigned to Sylvain Bauza (sylvain-bauza) | 09:03 |
| sfinucan | johnthetubaguy: In 'a54997c6', ndipanov extended the conditions that would cause resources to be freed by the resource tracker, rather than allocated | 09:03 |
| *** derekh has joined #openstack-nova | 09:03 | |
| johnthetubaguy | sfinucan: honestly, that stuff is harder to understand | 09:04 |
| johnthetubaguy | sfinucan: with shelve, you do release all resources | 09:04 |
| sfinucan | yes | 09:04 |
| sfinucan | johnthetubaguy: *but*, when we unshelve we don't change state | 09:04 |
| johnthetubaguy | sfinucan: unshelve should then Aquire all the resources | 09:04 |
| *** gjayavelu has joined #openstack-nova | 09:04 | |
| johnthetubaguy | oh... | 09:04 |
| johnthetubaguy | so thats bad | 09:04 |
| sfinucan | we stay in 'SHELVED_OFFLOADED', which causes that check to trigger again | 09:05 |
| johnthetubaguy | gotcha | 09:05 |
| sfinucan | causing a double free of resources | 09:05 |
| johnthetubaguy | nasty | 09:05 |
| sfinucan | yup | 09:05 |
| johnthetubaguy | there should be an unshelving state | 09:05 |
| johnthetubaguy | or something like that, I guess | 09:05 |
| sfinucan | exactly | 09:05 |
| *** thorst has joined #openstack-nova | 09:05 | |
| sfinucan | or send it to building | 09:05 |
| sfinucan | that was my main question | 09:05 |
| johnthetubaguy | yeah, building is probably the most accurate | 09:05 |
| johnthetubaguy | I wonder what rebuild does | 09:06 |
| openstackgerrit | Sergey Nikitin proposed openstack/nova: Fixed clean up process in confirm_resize() after resize/cold migration https://review.openstack.org/320478 | 09:06 |

| johnthetubaguy | sfinucan: looking at rebuild: https://github.com/openstack/nova/blob/master/nova/compute/api.py#L2475 | 09:07 |
| johnthetubaguy | sfinucan: looks like the resource tracker needs to look at the task state to see if its an add or remove of resources | 09:07 |
| johnthetubaguy | sfinucan: although that sounds aweful when I type it out like that | 09:08 |
| *** ijw has quit IRC | 09:09 | |

| *** tangchen has joined #openstack-nova | 09:10 | |
| sfinucan | johnthetubaguy: Yeah, it's an iffy one | 09:10 |
| johnthetubaguy | sfinucan: like mdbooth mentioned, long term, there are better ways to do this | 09:11 |
| johnthetubaguy | sfinucan: seems like it just needs trying out in the code, and see how it looks | 09:11 |
| snikitin | danpb: Hi, Daniel! I want to ask you one question about NUMA topology. In this spec http://specs.openstack.org/openstack/nova-specs/specs/juno/implemented/virt-driver-numa-placement.html we have property 'hw:numa_mempolicy=preferred|strict - memory allocation policy'. But I don't see it in Nova code. Was it implemented? Or you decided to remove it during implementation? | 09:12 |
| sfinucan | What do you mean? General improvements to the whole state machine or, how we do this particular case? | 09:12 |
| *** thorst has quit IRC | 09:12 | |
| mdbooth | Well each of the *_states currently implements a state machine in practise, except it isn't defined anywhere | 09:13 |
| mdbooth | There are a few weird bugs related to it | 09:13 |
| mdbooth | iirc migration can end up in 2 different states just because somebody used the wrong word at one point in history | 09:14 |
| openstackgerrit | Zhihai Song proposed openstack/nova: Add volume status check when deleting instances https://review.openstack.org/260339 | 09:14 |
| sfinucan | mdbooth: So I guess we need some way of making sure we don't do an invalid transition? | 09:14 |
| mdbooth | Yeah, I believe there's at least one patch up for this. Biggest problem now is bug compatibility, tbh. | 09:15 |
| mdbooth | Beause they're user-visible. | 09:15 |
| tangchen | tdurakov: Hi Timofey, I read your comment, and thank you for sharing your future work about task orchestration. | 09:15 |
| tangchen | tdurakov: I read this link. http://docs.openstack.org/developer/nova/conductor.html | 09:15 |
| johnthetubaguy | mdbooth: migration has two end states? you mean in the migration object? | 09:16 |
| *** permalac has quit IRC | 09:16 | |
| tangchen | tdurakov: So, is your ‘O’ release work relates to this one ? | 09:16 |
| mdbooth | johnthetubaguy: Don't recall the details, but one of them has 2 end states. | 09:16 |
| mdbooth | something like 'success' and 'finished' | 09:17 |
| *** dedery__ has quit IRC | 09:17 | |
| mdbooth | i.e. they both mean the same thing | 09:17 |
| *** dedery has joined #openstack-nova | 09:17 | |
| tangchen | tdurakov: IIUC, we need to clean up migration/resize processes and make them both in conductor, just like the scheduler. | 09:17 |
| johnthetubaguy | mdbooth: yeah, thats no in the main instance state, but agreed with the problems, we certainly have "error" and "failed" and no one can quite decide if they have a special meaning or not | 09:17 |
| johnthetubaguy | mdbooth: +1 on the bug compatible annoyance too | 09:18 |
| tangchen | tdurakov: And in this work, we can introduce state machine to enhance the code. | 09:18 |
| *** claudiub has joined #openstack-nova | 09:18 | |
| tangchen | tdurakov: Or would you please say more about the direction ? I'd like to help and I think I can start part of the work now. | 09:19 |
| sfinucan | mdbooth: johnthetubaguy: dumb question, but what do you mean by "bug compatibility"? | 09:19 |
| tangchen | tdurakov: Thanks. :) | 09:19 |
| mdbooth | sfinucan: The new version must have the same user-visible bugs as the old one | 09:19 |
| mdbooth | Because the user may now rely on them. | 09:19 |
| johnthetubaguy | sfinucan: need to keep the same broken behaviour, because its exposed via the API (we can now fix it in a microversion, but its complicated) | 09:19 |
| *** matrohon has joined #openstack-nova | 09:20 | |
| johnthetubaguy | yeah, that | 09:20 |
| mdbooth | i.e. the user writes a script which greps for 'finished', breaks when it changes to 'success' for consistency. | 09:21 |
| sfinucan | snikitin: afaik, 'hw:numa_mempolicy' wasn't implemented. 'strict' mode gave better performance and there were some funky things that I don't remember that prevented preferred being implemented | 09:21 |
| *** daemontool has joined #openstack-nova | 09:22 | |

| tdurakov | tangchen: hi, you are welcome. from my sight implementing Task API should be started with engine part(I think it's ok to use automaton here), then I'd try to reuse it for relatively small action, not live-migration, but resize, e.g. to understand how engine fits nova's requirements, only after first 2 step I think it's worth to expose API over REST. | 10:11 |

| dims | alaski : had to revert fixtures===3.0.0 to get gate-nova-tox-db-functional back on its feet | 10:33 |
| avishay | Hey all. I noticed that there is no support for network boot (PXE). Would this be an interesting contribution? | 10:33 |
| danpb | paul-carlton: presumably, we'll re-consider possible API extension at a later date with separate spec | 10:33 |
| dims | bauzas : ^^ | 10:33 |
| danpb | avishay: it has been proposed before, but was rejected | 10:34 |
| danpb | avishay: personally I'd be happy to see pxe supported | 10:34 |
| avishay | danpb: OK will look at past specs - thank you! | 10:35 |

| * tdurakov reading comment | 10:44 | |
| danpb | kashyap: regardless of that i think what's being done is wrong | 10:45 |
| danpb | as mentioned in my reply, nova should explicitly turn on/off flags it doesn't want | 10:45 |
| kashyap | danpb: What's being done in the Gate, you mean? | 10:45 |
| danpb | rather than trying to invent new models | 10:45 |
| kashyap | Didn't see your reply yet, /me goes to fetch the email | 10:45 |

| tdurakov | johnthetubaguy: afair post_live_migration_at_destination is rpc cast, so it's not guaranteed to happen after | 11:04 |

| cdent | paul-carlton: we haven't really discussed it, yet, as the "old" way will continue working for basically forever so there's no rush | 11:10 |
| *** vishwanathj has joined #openstack-nova | 11:10 | |
| cdent | the main goal was to get it in there for people who are creating their own clients that might also be speaking with other openstack project that are already using the new form | 11:10 |
| cdent | in that context it would be bad for nova to the odd-project-out | 11:11 |

| *** thorst has joined #openstack-nova | 11:14 | |
| johnthetubaguy | oh wait, there is a way to do that | 11:14 |
| johnthetubaguy | I think you don't raise the max_version, but not sure if thats still working as originally planned | 11:14 |

| *** hoangcx has quit IRC | 11:17 | |

| dansmith | yeah | 14:05 |
| artom | alaski, hrmm, so it'b be preferable to outright add a field to RequestSpec? | 14:05 |

| tobasco | jaypipes: after reading the bp for the resource-objects I must say you're my hero if you get this merged :] | 14:36 |
| johnthetubaguy | paul-carlton: do you mean the compute RPC api? | 14:38 |
| *** vishwanathj has quit IRC | 14:38 | |
| paul-carlton | calling if not cell_client.can_send_version(version) returns False, i.e. it does but since I'm not specifying the target node at this point I'm guessing this is just checking the message system for the cell | 14:38 |
| sdague | dane-fichter: I've got a fix | 14:38 |

| *** ducttape_ has quit IRC | 14:40 | |
| sdague | the failure at L136 was the non printing characters, but the failure at L200 was the fact that the cert not staying indented dropped you out of the code block, then the exception for code blocks was lost | 14:40 |

| dansmith | paul-carlton: you don't get to make that decision | 14:40 |

| sdague | that's what the unprintables were | 14:50 |
| dansmith | paul-carlton: you can also set that to auto and it should calculate it on service startup based on the service records in the DB | 14:50 |
| clarkb | kashyap: we try to point the cloud providers at the issue but it is up to them to file. not sure what elsr I can do. in the past I have tried filing bugs with minimal info and upstreams get cranky and ignire you (this includes nova) | 14:50 |

| clarkb | no one seems willing to try to sort it out via bisect or whatver | 14:51 |

| kashyap | clarkb: Now Nova reports libvirt versions in the logs? | 14:52 |
| sdague | clarkb: which bug is that? | 14:52 |

| sdague | clarkb: url? I don't know all 1000 bugs by concept :) | 14:52 |
| paul-carlton | but if some compute nodes are at version 4.12 while others are at 4.13 then setting upgrade_level to auto will mean can_send_version will tell conductor the level in DB is ok but I still have compute nodes on old versions | 14:53 |
| sdague | kashyap: anyway, figuring out nested kvm issues can be a long term goal, but it's a massive distraction to moving forward here | 14:53 |
| dansmith | paul-carlton: it would help if you would use my nick.. I'm not always looking at the screen | 14:54 |
| sdague | danpb provided a potential very simple compat check change, that should be tried today | 14:54 |
| dansmith | paul-carlton: and no, that's not right. the auto check clamps to the oldest version supported by all compute nodes.. that's the point | 14:54 |
| sdague | and if the fallout is minimal, move forward that way | 14:54 |
| kashyap | sdague: Heh, I know for sure it's a "long term" goal since Paris Summit. Not trying to get it resolved here. | 14:54 |
| kashyap | Okay | 14:54 |

| *** roeyc has joined #openstack-nova | 15:01 | |

| sdague | can we instead focus on actual ways to move forward on the blocking issue? :) | 15:02 |
| danpb | sdague: clarkb kind of makes me want to expose info about the software versions running on the compute host to the tenant user....except cloud admins would probably come after us with pitchforks & burning torches if we do that | 15:02 |
| sdague | danpb: yeh, they would all patch it out | 15:02 |
| *** code-R has joined #openstack-nova | 15:02 | |
| kashyap | danpb: I thought Guru Meditation also reports libvirt version? Or am I just being silly? | 15:03 |
| danpb | kashyap: its only visible to cloud admins - not tenant users | 15:03 |
| kashyap | Ah-ha | 15:04 |
| danpb | so if you're using a public cloud you can't get it | 15:04 |
| kashyap | Thanks, I thought Clark had access to admin tenants. But he now clarified, no... | 15:04 |
| danpb | kashyap: CI infra runs on a variety of public clouds | 15:04 |

| *** armax has joined #openstack-nova | 15:05 | |
| mnaser | for context: configdrive is attached as "vdz" in the libvirt xml config (last position), however, the operating system does not align it in that way, typically vda will be ephermal and vdb would be configdrive. when you attach a new cinder volume, it will "append" to the existing config, requesting "vdb" (second position).. however.. in the libvirt config: vda is ephermal, vdb is cinder volume, vdz is configdrive. however, in the VM, vda | 15:05 |
| mnaser | is ephermal, vdb is configdrive and vdc becomes the cinder volume (because it was just hot plugged). however, when you reboot the server, the "correct" order is restored and vdb/vdc order becomes messed up again | 15:05 |
| mnaser | sorry if that was too much and probably did a bad job explainined it | 15:05 |
| danpb | basically from the nova POV, the device names you give are totally unrelated to guest OS device names | 15:05 |
| mnaser | yes, nova relies on libvirt's device names, but even those aren't correct | 15:06 |
| sdague | right, which is why we got rid of them | 15:06 |
| danpb | at host side the device names merely indicate a relative ordering of disks | 15:06 |
| mnaser | this is why we've suggested for our customers to mount by labels | 15:06 |
| mnaser | or UUIDs in /etc/fstab | 15:06 |
| *** ctrath has joined #openstack-nova | 15:06 | |
| danpb | yep, that's the only sane way to deal with it right now | 15:07 |
| sdague | yeh | 15:07 |
| danpb | in the near future nova will have the role device tagging support | 15:07 |
| mnaser | it does get a bit frustrating when you have 2-3 block devices and you dont know which one is which :( | 15:07 |
| danpb | which will let you identify disks based on a user specified string tag | 15:07 |
| *** rcernin has quit IRC | 15:07 | |
| danpb | which is nice because it'll work even if there's no filesystem yet formatted on the volume | 15:07 |

| mnaser | because i wonder if this has to do with the fact there might be multiple levels of nesting happening here.. | 15:17 |
| clarkb | sdague: mnaser also we saw it in OVH which was our first cloud to allow nested virt | 15:17 |
| jroll | I assume the nested virt was on kvm only though | 15:17 |
| clarkb | I think we had it disabled by the time we ran tests on vexxhost | 15:17 |
| paul-carlton | dansmith, I don't think it is viable to wait for all compute nodes to be upgraded there may be some compute nodes that are down and can't be restored any time soon due to hardware issues | 15:17 |
| clarkb | but internap and vexxhost do have the ability too iirc | 15:17 |
| mnaser | we're enabling it right now | 15:17 |
| johnthetubaguy | pumaranikar: thats a glance spec that has a -2, I would raise that with glance folks | 15:18 |
| clarkb | mnaser: ya we disable in in the tests by forcing qemu even if the hypervisor supports it | 15:18 |
| johnthetubaguy | pumaranikar: looks like it needs moving to newton | 15:18 |
| clarkb | mnaser: I think it is great for hypervisors to support it fwiw, we just aren't in a great position to take advantage of it yet | 15:18 |

| paul-carlton | dansmith, is there a good way to access the services record for the target node to get the version? | 15:18 |
| mnaser | kvm module has to be loaded with nested virt enabled and then the vmx feature flag has to be exposed to the vm as well | 15:19 |
| mnaser | but i will assume that these providers are just using host-passthrough ? | 15:19 |
| pumaranikar | johnthetubaguy, I am working with glance folks. Just want to have your feedback. It is useful for nova. | 15:20 |
| *** dane-fichter has quit IRC | 15:20 | |
| mnaser | because we were looking to run it without host-passthrough but only exposing the vmx extension instead (which could maybe be related?) | 15:20 |

| jroll | (asking for a friend) | 15:20 |

| mnaser | clarkb: but it's not exposing the full cpu with all the features? | 15:21 |

See: Backports for Ironic driver: https://review.openstack.org/323477 Unavailable hosts have no resources for use + https://review.openstack.org/323196 Ironic nodes with instance_uuid are not available are up for review against the stable/mitaka branch | 16:18 |

| openstackgerrit | Hironori Shiina proposed openstack/nova: Remove mox from tests/unit/conductor/tasks/test_live_migrate.py(3) https://review.openstack.org/312529 | 20:38 |
| sdague | I think out of the box you are going to get 1 worker / core for API and conductor at least | 20:38 |
| smcginnis | sdague: Great, thanks. Hitting connection limits on my database and I want to make sure there's not an issue before I blindly bump up the limit. | 20:38 |
| sdague | that's tunable | 20:38 |
| sdague | oh, and you'll get that number of metadata workers | 20:39 |
| smcginnis | sdague: Is it recommended to do some tuning on that for a fairly small deployment? Or do you think I'm fine just bumping my connection limit up? | 20:39 |
| *** irenab has quit IRC | 20:39 | |
| sdague | if you don't need that level of concurency, tune down the workers, you'll save ram | 20:39 |

| armax | I have a question for the Nova folks, looking for pointers in areas you might be working on for API usability | 20:59 |
| armax | I recall during the last mid-cycle there were discussion on how to enable users to know in advance whether a backend supported a feature beforehand | 21:00 |
| *** ivase has quit IRC | 21:00 | |
| armax | I was looking on nova-specs, openstack-specs etc, but nothing stands out, at least nothing recent | 21:00 |
| armax | anyone? | 21:01 |
| *** akshai has quit IRC | 21:02 | |
| *** daemontool_ has quit IRC | 21:02 | |
| melwitt | armax: do you mean like the feature support matrix or something provided through an API? http://docs.openstack.org/developer/nova/support-matrix.html | 21:02 |
| armax | melwitt: exactly | 21:03 |
| alaski | armax: I am not aware of any work happening this cycle. There is work around policy which is a precursor to exposing it in the API, and nothing around capabilities | 21:03 |
| *** thumpba has quit IRC | 21:03 | |
| armax | melwitt: I understand the latter is mostly for human consumption though | 21:03 |
| *** rama_y has quit IRC | 21:03 | |
| armax | alaski: ack, which would be this one, I suppose: https://review.openstack.org/#/c/245629/ | 21:04 |
| edleafe | dims: noticed no one answered you question about Watcher polling the Nova API. It doesn't - it uses telemetry data | 21:04 |
| edleafe | dims: It only talks to Nova to request the live migrations once it determines that instances should be moved | 21:05 |
| alaski | armax: I was thinking of https://review.openstack.org/290155 | 21:05 |
| alaski | there is also https://review.openstack.org/#/c/289405/, which I don't think will get into this cycle | 21:05 |
| armax | alaski: right, I saw that one too | 21:06 |
| armax | melwitt, alaski: thanks for shedding a little more light | 21:06 |
| armax | appreciate it | 21:06 |
| melwitt | armax, alaski: this looks related to what you're talking about too https://specs.openstack.org/openstack/nova-specs/specs/mitaka/approved/expose-host-capabilities.html | 21:07 |
| armax | alaski, melwitt: reason why I brought it up is because someone in Neutron-land is exploring this field here: https://review.openstack.org/#/c/317635/ | 21:07 |
| *** kylek3h has joined #openstack-nova | 21:07 | |
| alaski | melwitt: yeah, that would get us closer to being able to expose capabilities | 21:08 |
| armax | and I field there’re off the wrong foot, I had a faint recollection of some effort speareheaded by the Nova team and was looking for pointers | 21:08 |
| sdague | armax: it's a thing we want to do, but here are the more pressing issues | 21:08 |
| armax | sdague: I hear you | 21:09 |
| sdague | policy intersects with this, because people tune features off in policy (today) | 21:09 |
| sdague | so until that's into code, and known in advance, you can't really give a complete story about features people get | 21:09 |
| sdague | and... most consumers of the API are humans | 21:09 |
| armax | sdague: makes sense | 21:09 |
| sdague | and a lot of the cruddy areas can be at least clarified with docs (like features that are unlikely to exist on most clouds) | 21:10 |
| sdague | so those 2 are our pushes this cycle | 21:10 |
| *** thorst has quit IRC | 21:10 | |
| *** jichen has quit IRC | 21:10 | |
| sdague | and see how far we get, and if we can start to crack this one next cycle | 21:10 |
| armax | sdague: understood, the more you make me think the more I believe that https://review.openstack.org/#/c/317635/3/doc/source/driver-capability-discovery.rst is not at all viable long term | 21:11 |
| alaski | looking through it quickly I have to agree | 21:11 |
| armax | alaski: thanks | 21:12 |
| alaski | when I have more time to read through it fully I'll add some comments | 21:12 |
| sdague | I need to pop off to handle dinner, but happy to chat about it tomorrow if there is more to chat about | 21:12 |
| armax | alaski, sdague thanks! | 21:12 |
| armax | I think your perspective would be useful in this area | 21:12 |

| alaski | armax: one thing that may be different between Nova/Neutron is that with Nova there are few differences between drivers when booting, it's only after boot that they really diverge. So to me capability exposure has been attached to what can an instance do, not what can a user do | 21:13 |
| alaski | I don't know if the thinking in Neutron is the same | 21:13 |
| armax | alaski: in Neutron things are typically more convoluted :) | 21:14 |
| alaski | that's what I figured :) | 21:14 |
| armax | alaski: the same would apply to properties or things one can do with ports | 21:14 |

| armax | but the extent or resources exposed by the API is such that the landscape is a lot more involved | 21:15 |
| openstackgerrit | Hironori Shiina proposed openstack/nova: Remove mox from tests/unit/conductor/tasks/test_live_migrate.py(4) https://review.openstack.org/312589 | 21:16 |
| alaski | armax: gotcha. so that may mean thinking about this differently between the two projects, but hopefully we can have a mutual conversation about directions here. Thanks for raising this | 21:18 |
| armax | alaski: indeed | 21:18 |
| armax | alaski: ideally we’d both learn from each other experiences and find a common ground we can both leverage | 21:19 |
