lifelessJayF: I dunno - sorry - I've always gone by the docs on the abstract base class + walking through the compute code00:11
JayFlifeless: at a minimum, is there a ... reference driver? i.e. one I can look at the implementatino and know it's doing it right? I'd presume that'd be libvirt?00:11
lifelessyes00:11
lifelesslibvirt is the canonical way00:12
JayFcool, I'll keep reading the rescue method on that then :)00:12
JayFthanks00:12

mikaltonyb: so, I think we might be interested in backporting https://bugs.launchpad.net/nova/+bug/1567807 to Mitaka...00:22
openstackLaunchpad bug 1567807 in OpenStack Compute (nova) "nova delete doesn't work with EFI booted VMs" [Low,Triaged]00:22
mikaltonyb: the code was new in Mitaka and it seems like we might have not had enough testing?00:23
tonybmikal: is there actually a review?00:24
openstackgerritDiana Clarke proposed openstack/nova: Minor updates to the how_to_get_involved docs  https://review.openstack.org/30417500:24
mikaltonyb: there is a patch from an upstream dev00:24
mikaltonyb: but I feel like we need more tests too, so someone needs to pick it up and run with it00:24

alaskilifeless: at first glance your latest comment on the fixtures PR seems good. and not supporting patching in unbound methods would greatly simplify things, and should not be a big loss. However it is 2112 local time so I'm going to go through it again with fresh eyes in the morning01:12

claudiubpaul-carlton1: notepad 'C:\Program Files (x86)\Cloudbase Solutions\OpenStack\Nova\etc\neutron-hyperv-agent.conf'12:27
alaskicdent: so I think you're in the somewhat insane territory. I think the hierarchy works fairly well to more naturally model some things, cellsv1 does a similar thing. But my immediate questions are:12:27
alaskihow do you actually model everything. this was a cellsv1 challenge where the cells scheduler could only think in terms of flavor slots available12:28
* cdent was hoping for completely insane, then I could get a nice new home12:28
alaskihow do you keep everything in sync, another cells split scheduler challenge12:28
alaskihow do you get there from here12:29
cdentyup, all very good questions12:29
alaskiand finally, some people really want simple things for the simple case and this seems complex even in that case12:29
alaskihow can the complexity be downgraded when not needed12:29
cdentgiven this is  more of an intellectual exercise than solution my responses would be:12:29
cdenta) "everything" is always too much, so don't do it, enforce constraints12:30
cdentb) the problem with sync is why I intuitively don't like the database solution12:30
cdentc) if you want simple just use the bottom of the hierarchy12:30

claudiubpaul-carlton: run systeminfo.exe14:56
BobBallcoreywright: bdm['mount_device'] should be able to uniquely identify it I think?14:56
*** gszasz has joined #openstack-nova14:56
coreywrightBobBall: we can use the mointpoint, a host-port-iqn triplet, the volume id, etc to get a unique key to share between the source and destination, but to get the SR uuid (ie the value that corresponds to whatever key you want to use) you have to use the volume id (at least for the old-style; host-port-iqn for the new-style)14:56
claudiubpaul-carlton: there's a section called: Hyper-V Requirements in the output14:56
coreywrightBobBall: to generate the needed SR uuid14:57
claudiubpaul-carlton: it checks if your system passes the hardware requirements for hyper-v: https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/quick_start/walkthrough_compatibility14:57
mehdi1hi dear developer. when nova.compute.rpcapi make a RPC request for example in reboot_instance  https://github.com/openstack/nova/blob/master/nova/compute/rpcapi.py#L719  this request is received by the given Compute Node. In class ComputeManager in  nova.compute.manager.py there is a same  method       https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3008  which is execute and it continues the process .  I want to know weather this14:57
coreywrightBobBall: so i'm cool with using the volume uuid, since you have to have it to calculate the sr uuid, which is what we really need14:57
BobBallcoreywright: I meant that the mountpoint is in XAPI so we can use BDM['volume_id'] as the key and map from the mounted volume on the vm (using bdm['mount_device']) back to the SR uuid?14:58
*** tbachman has quit IRC14:58
BobBallcoreywright: It'd be nicer not to have to generate it in two places.  The "right" uuid is only known by XAPI so we can query XAPI to figure out which SR UUID we should be using14:58
BobBallcoreywright: That way it doesn't matter if we change or add more generation methods in the future14:58

paul-carltonclaudiub, So I can run this on Windows 10 pro 64 bit?15:00
*** mvk has joined #openstack-nova15:00
BobBallcoreywright: With the mount point from BDM you can identify the vbd (see volume_utils.find_vbd_by_number) and get the SR from there (vbd->vdi->SR) to get the UUID.  Then pass Cinder's volume ID and the SR uuid through to the destination as in John's suggested change and it should all be good15:00
claudiubpaul-carlton: no, it also runs on windows server 2012 r215:00

BobBallcoreywright: find_vbd_by_number is used by detach volume, so it __must__ be correct15:02

oomichi_sdague: then it would be better to clarify 'this is a part of swagger' on qa-spec and tempest, I feel17:01
sdagueif you are going to build actual swagger yaml files in tempest, that's cool. But this is not that. It's still doing all the odd copying in python of pieces of docs.17:01
sdagueoomichi_: but, swagger isn't designed to be used in pieces like that17:01
*** jwcroppe has quit IRC17:01
sdagueif you use the word swagger in this, people are going to believe that this is what swagger is, and it's not17:02
sdaguethen they are going to copy that pattern into lots of other projects17:02
*** vishwanathj has quit IRC17:03
*** akshai has quit IRC17:03
sdagueand we'll end up with a lot of not swagger, called swagger17:03
sdaguewhich is very bad17:03
oomichi_sdague: in long term, I hope response schemas from tempest into nova and will build whole swagger specs in nova tree17:03
*** akshai has joined #openstack-nova17:03
sdagueoomichi_: we've already proved that's not possible17:03
sdaguethere are completely untractable problems with swagger and our API, like actions and microversions17:04
dansmithalso intractable problems I think17:04
sdaguedansmith: :P17:04
sdagueoomichi_: so until there are solutions for those, I don't actually understand why any time is spent on shuffling other parts of the datastructures around17:05
*** ljxiash has joined #openstack-nova17:05
alaskidansmith: is there an example of handling the same problem you pointed out in https://review.openstack.org/#/c/298455/9/nova/objects/build_request.py ?17:05
dansmithalaski: no, reviewing your stuff made me realize that we probably have that exposure elsewhere, but for objects that don't change as much as instance17:05
alaskiokay17:06
dansmithalaski:  you understand that if we store instance 2.10 in the db, and then an older node that supports only 2.8 tries to read and obj_from_primitive() it, it'll fail with "I don't know about 2.10" right?17:06
dansmiththat's all I'm saying17:06
dansmithit could be that this is not a problem here because of the order in which services should be upgraded17:06
dansmithand/or when this is read17:06
alaskiyeah, I get that. I'm just trying to think of how best to deal with it17:06
oomichi_sdague: if providing swagger specs via REST API, microversions can be passed.17:06
dansmithif we can just handle that case and do something smart with it, then that's better than nothing17:07
oomichi_sdague: like by specifying a microversion on the header to get swagger spec.17:07
alaskidansmith: how do we currently handle a mixed version nova-api case17:07
oomichi_sdague: but yea, action is very difficult to be handled17:07
alaskidansmith: the same issue exists there I think17:07
sdagueoomichi_: that doesn't really solve discovery at all, because you then would have to iterate every microversion to know what's available17:08
*** raildo is now known as raildo-afk17:08
dansmithalaski: well, we don't have anything like this now.. if you run multiple nova-apis of different versions, nobody sends then instance objects, nor do they read serialzed instance objects out of the database that might be of a newer version17:08
*** ircuser-1 has joined #openstack-nova17:08
sdaguealso, it again isn't swagger17:08
alaskidansmith: how is that last part accomplished?17:08
sdaguebecause swagger is a static file that describes your API, not something that you need to know how to make a request to get17:08
*** browne has joined #openstack-nova17:08
dansmithalaski: it's not currently, that's my point17:09
dansmithalaski: lets redirect this to: where are all the places we'll deserialize your stored instance?17:09
alaskiyeah, was about to explain that17:09
dansmithalaski: is it just by the api-level in the case where the instance hasn't been created?17:09
*** ljxiash has quit IRC17:09
sdagueoomichi_: I do understand that you would like to find a way to make swagger work here, but I feel like there are enough unsolved hard problems that it's really not clear that it can ever work17:09
alaskidansmith: so this is written in the api, and could later be read by nova-api or nova-conductor17:09
*** liusheng has quit IRC17:10
dansmithalaski: do you want to jump on a hangout?17:10

*** hoangcx has quit IRC17:12
*** doug-fish has quit IRC17:13
oomichi_sdague: ok, I see the point. let me define the goal for swagger17:14
sdagueoomichi_: yeh, create a higher level spec to try to explain where you see this going, and why it's worth the investment17:14
oomichi_sdague: 1) swagger spec needs to contain all data(all microversions, actions) in a single file17:14
*** zz_dimtruck is now known as dimtruck17:15
sdagueright, neither of which can be described by swagger itself natively17:15
*** jistr has quit IRC17:15
oomichi_sdague: 2) need to find a concrete way before actual work including current tempest one17:15
*** gagehugo has quit IRC17:15
oomichi_sdague: 3) before doing that, concentrate on actual doc fixing for users17:15
oomichi_sdague: thats all17:16
sdaguebecause if we serve swagger that uses any extensions 'x-' then most of the value of using swagger is thrown out the window entirely, as no 3rd party tooling will understand it.17:16

diana_clarke1dansmith: Do you have a couple of minutes to chat about the database poison warnings?19:39
mriedemsdague: oh, ok19:39
dansmithdiana_clarke1: yeah19:39
sdaguealthough, it would also hold to the image proxy as well19:39
sdagueif our image proxy needs to work with v219:39
diana_clarke1dansmith: some of them are only because this decorator was added: select_db_reader_mode19:39
sdaguethere is kind of no reason to really have it work with v1 long term19:40
sdaguethat's just 2 code paths to collect bugs19:40
diana_clarke1dansmith: but otherwise they aren't using the db at all19:40
mriedemsdague: i thought we already talked about this?19:40
*** omnipresent has joined #openstack-nova19:40
dansmithdiana_clarke1: right, but the thing that I'm mocking to throw that warning is a thing that tests cannot touch unless they use the db fixture19:40
bauzasmriedem: https://www.openstack.org/summit/austin-2016/summit-schedule/events/9090 is exactly what I wanted to discuss19:40
diana_clarke1dansmith: I can bump the mocking one level higher (like I did in the patch you saw earlier)19:40

*** doug-fish has quit IRC19:42

sdaguemriedem: ok, so I think you misunderstand me19:42
*** zenoway__ has quit IRC19:42
* dansmith stands by for the real question19:42
sdaguenova has an API, it looks, kind of like glance v119:43
sdagueand today it talks to a glance v1 server19:43
*** zenoway__ has joined #openstack-nova19:43
sdagueonly19:43
mriedemyup19:43
sdaguemy point is, glance v1 servers are not long for this world19:43
sdagueso we should make it talk to glance v2 servers to get roughly the same info19:43
mriedemso glance plans on deleting it's v1 API?19:43
diana_clarke1dansmith: If the select_db_reader_mode decorator is the only problem with the tests, perhaps I shouldn't be bumping the mocking up one level, but addressing the new decorator wrt testing. Or just stubbing that decorator19:43
sdaguemriedem: yes19:44
sdaguethat's the whole reason they want us to move over19:44
*** sc68cal has joined #openstack-nova19:44
sdaguenova is basically the only reason they can't19:44
diana_clarke1dansmith: That's not the case for all the offending tests, but it is for many of them.19:44
*** zenoway has quit IRC19:44
*** sc68cal is now known as Guest4887319:44
mriedemyeah, i didn't think they were actually going to delete it though because of the nova api, and we don't delete our apis, at least i thought we didn't19:44
dansmithdiana_clarke1:  it depends on the test.. if the test really doesn't need the DB, and is just mocking out at this low level just because it's convenient, then mocking up a level is a good plan19:44
*** zenoway has joined #openstack-nova19:44
sdagueso we should honestly plumb in glance v2 code in a way that make it easy to delete all our glance v1 connectivity19:44
dansmithdiana_clarke1: we haven't always had the object layer, so a lot of conventional tests (and test writers) mocked at the db level because it was the most convenient19:45
*** pwnall has quit IRC19:45
sdaguebecause, that's only got a cycle or two left where it's a thing19:45
diana_clarke1dansmith: I see. So regardless, it's a step in the right direction.19:45
*** zenoway has quit IRC19:45
dansmithdiana_clarke1: so my answer is "it depends but probably for most cases, it's cool to mock above"19:45
sdagueand if we spend all this time on common code abstraction layers, then we have to live with all that gorp when we don't have a v1 any more19:45
mriedemsdague: so do we plan on translating glance v2 responses to glance v1 style in the nova images api?19:45
*** omnipresent has quit IRC19:45
dansmithdiana_clarke1: yeah, probably in most cases it's an improvement worth making anyway19:45
*** Sukhdev has quit IRC19:45

*** zenoway_ has quit IRC19:46
dansmithdiana_clarke1: but again, it depends and I reserve my right to differ in each situation depending on the test :)19:46
diana_clarke1dansmith: ;)19:46
sdagueuser->nova-images->glance.v2->glance.v1(ish)->user19:46
sdaguethat's what that line means to me at least19:46
mriedemyes,19:46
mriedemi thought earlier up you were saying we essentially were going to make a backward incompatible change to the nova images api19:46
mriedemb/c we wouldn't have glance v119:47
mriedemand it would be pointless to return a glance v1 like response19:47
*** omnipresent has joined #openstack-nova19:47
dansmithdiana_clarke1: smaller patches that change similar groupings of code will reduce the concern of doing a bunch of work when the decision might be wrong. I'll be glad to opine on those early to guide19:47
sdagueright, so, I backed off that mostly19:47

mriedemand, for example, i dont think we have ci coverage for ephemeral storage backed by lvm21:24
*** omnipresent has quit IRC21:24
xyang1mriedem: oh, so no requirement?21:24
mriedemidk21:24
*** omnipresent has joined #openstack-nova21:25

mriedemwe did require third party ci for virtuozzo (ploop) though21:26
*** zenoway has joined #openstack-nova21:26
xyang1mriedem: that is ephemeral as well?21:27
mriedemi think so, i'd have to check21:27
xyang1mriedem: ok21:27
mriedemthe experimental lxc job might be using images_type=lvm, i'd have to check on that also21:27
*** e0ne has quit IRC21:27
mriedemthomasem: is the lxc job using images_type=lvm?21:28
*** omnipresent has joined #openstack-nova21:28

*** omnipresent has joined #openstack-nova21:30
thomasemOn that topic, the whole Fedora 23 thing didn't pan out quite like expected.21:30
mriedemxyang1: so i'd lean toward a third party ci for scaleio also given we have test coverage (somewhat) for lvm, ploop and ceph21:30
xyang1mriedem: so we will run the same set of tests21:30
*** hdd has quit IRC21:30
*** omnipresent has quit IRC21:30
thomasemMore failures in upstream gate with that than ubuntu-trusty, weirdly enough, yet way more stable in my own gate simulations. So, I must have been doing something differently.21:30
*** zenoway has quit IRC21:31
xyang1mriedem: sure, we'll look at how the CI is set up for ploop21:31
*** zenoway has joined #openstack-nova21:31

mriedemthomasem: are you running tests concurrently and on the same size vm as upstream?21:32

xyang1mriedem: what is the deadline for having running CI, spec merge, code merge?21:32
mriedem8 CPU, 8GB RAM vm21:32
thomasemmriedem: yep21:32
thomasemperformance flavor, like indicated21:32
mriedemxyang1: we don't have one yet, we discuss the schedule at the summit21:32
thomasemI think the image might be different, though, since I wasn't using the one built like upstream, I suspect.21:32
xyang1mriedem: sure21:32
*** omnipresent has joined #openstack-nova21:32
mriedemxyang1: right now we're not accepting specs for new things before the summit21:32
thomasemI was using a Rackspace experimental Fedora 23 image at the time.21:32
mriedemsince we're trying to flush the backlog of stuff from previous releases21:33
thomasemexperimental, but almost ready for production21:33
*** omnipresent has quit IRC21:33
xyang1mriedem: ok, but will you open up after the summit?21:33
mriedemxyang1: yes21:33
xyang1mriedem: thanks21:33
mriedemi'm just not sure for how long right now21:33
thomasemSo, I suspect the answer lies somewhere in the difference between how the image is made for upstream gate vs. how I configured that one.21:33
*** omnipresent has joined #openstack-nova21:33
xyang1mriedem: ok21:33
*** omnipresent has quit IRC21:34
thomasemEither way, with the clear_volume=none set I was seeing great progress with ubuntu, so, when I can clear my plate enough to continue work on it, I'll attack that next. :)21:34

snetioomichi, When I tried this, instance was moving to Error State. This initialize_connection is called during pre live migration. Bug states that instance moving into Error state when the precheck fails was not appropriate.22:35

oomichisneti: in addition, this problem doesn't seem due to API users(not clients)22:39
oomichisneti: the client is nova in this case from cinder POV.22:39
