*** openstackgerrit has joined #openstack-nova10:17
ajobauzas: but we're looking into ways to push neutron data to the scheduler, and add plug points into it, so neutron could influence scheduler decissions too, based on resources10:17

ajo(like availability of certain networks on certain compute nodes, or the availability of bandwidth, etc..)10:17

johnthetubaguythe idea of a pool of resources consumed by instances10:18
johnthetubaguyright now everything comes from the compute node10:19

johnthetubaguyjaypipe's spec unhooks that link10:19
ajojohnthetubaguy , I will start by reading the spec, thanks a lot10:19
johnthetubaguynow, IP addresses or cinder volumes, are all nice groups of shared capacity you might need, that could be co-located with hosts10:20
johnthetubaguybut yeah, shared storage is the basis of the split here10:20
johnthetubaguyconsider various pools of shared storage attached to differenet groups of hosts10:20
johnthetubaguybasically the same model we need for external projects10:20
bauzasjohnthetubaguy: since I have pretty low memory in my brain (like 32KB), I don't exactly remember the details, but I remember ndipanov talking about some neutron bits at the end of the SR-IOV session10:20
ajojohnthetubaguy , I was also considering the option to provide discoverable "scheduler bits" (not sure what's the proper name here) which could be published by other projects, and consumed by the scheduler in realtime10:21
ajobauzas  ^10:21
johnthetubaguyajo: not sure I get the context there, what the problem you want to solve?10:21
ajowith the proper api, so, those would influence the decission, based on the information previously pushed by -whatever-10:21
bauzasajo: yeah, the paradigm is that projects push stats to the scheduler, not the scheduler getting those10:21
johnthetubaguythat should be in that spec of jays10:22
ajojohnthetubaguy : for example, bandwidth availability, it's a consumable resource on compute nodes,10:22
johnthetubaguywell its acutally missing right now10:22
bauzasajo: but I feel we discussed that in Tokyo, but my brain is playing with me10:22
johnthetubaguyah, so that one is a bit different10:22
ajobauzas , I think probably, with Ihar and NIkola Dipanov, I wasn't there this year, sorry guys ':)10:22

*** subscope has quit IRC10:51
ajobauzas , johnthetubaguy , I read the spec, what I was thinking of is tangential to Jay's spec. In the neutron case we are not looking for host aggregate resource pools (yet), but only compute-node resources. But we could need to push new resource types, and values for compute nodes from an "extension" to the nova-compute set in place by neutron (for example), or let the neutron-*-agent do it, so the scheduler would have that available.10:52
ajo And them, plug something into the scheduler, to consider that information at scheduling time.10:52
ajoand then.10:52
*** exploreshaifali has joined #openstack-nova10:53
*** subscope has joined #openstack-nova10:53
ajoSimple example, compute node 1 has access to external networks A & B, and pushes that to the scheduler database,  compute node has access to B & C, does the same...10:53
ajoVM is requested with port A (connected to net C)...10:54
ajothe scheduler may need to send the VM only to compute node 210:54
ajo(sorry I ommited the node 2 part)10:54

bauzasajo: sorry, I'm just in the middle of investigating a CI problem that seems to fail 100% of the jobs10:58
ajoanother case: neutron-*-agent (or neutron plugin into nova-compute) gather and declare the amount of bandwidth it's available for every network on each compute node., (we could think of updating such information from the computes as resources go away by new ports, but that would be racy...), we should probably have another plug point (somewhere) to redouce the count of those resources.10:58
ajobauzas : ack10:58
ajobauzas : consider trying oslogmerger (https://github.com/mangelajo/oslogmerger  / pip install oslogmerger) if you need to correlate several logs from the run10:59
ajobauzas , you just give it a list of URLs to the logs, and an alias to each url, and will dump via STDOUT a correlated/coalesced log10:59

johnthetubaguyajo: OK, so certain networks only available on certain hosts, that similar to the cinder case, makes sense11:06

ajoI need to re-read jay spec, may be that can be generalized to also track compute-node only resources in a modular way (if that makes any sense, probably not..)11:11
johnthetubaguyajo: the bandwidth on the node, did come up at some point, for that one, I think you need to read the resource object spec: http://specs.openstack.org/openstack/nova-specs/specs/mitaka/approved/resource-objects.html11:12

*** markvoelker has quit IRC11:14
bauzasajo: if you see jaypipes's spec, you'll see that I left a few comments for decoupling the aggregate bits aiming to solve the 'multi-hosts' issue from the other bits aiming to solve the heterogenous resources issue11:14
ajobauzas: aha, that'd make sense11:14
bauzasajo: the aggregate proposal from jay is just a way to have one concept for grouping resources in case you need to group them11:15
bauzasajo: so jay proposed to reuse the concept of aggregates, which I'm okay with thaty11:15
*** stevemar_ has quit IRC11:15
*** korzen has joined #openstack-nova11:16
bauzasajo: but IMHO, if you don't need to group resource providers, then you can directly have a specific resource provider that doesn't need an agg11:16
bauzasthe agg is just the resource provider in cause it's a shared resource11:16
bauzascase*11:16
ajobauzas: in our most complex case (tracking the available bandwidth on compute nodes),11:17
bauzasajo: well, that one is a bit different11:18
ajowe would need to push information about the avail bandwidth (per network), and then, provide some way to make that consumed.11:18
ajobauzas : and it's neutron responsibility to know how much bw an specific port consumes11:18
bauzasajo: do you want to give b/w information from the VIF standpoint, or from the port ?11:18
ajobauzas, we have that now decoupled from the port, by a reference to "QoS policy id"11:19
bauzasI see11:19
bauzasbut what's the relationship ?11:19
bauzasone qos id per router or port ?11:19
ajoqos policies are like "flavors"11:20
bauzasI guess you can set a policy per port, right?11:20
ajo1 policy : N ports11:20
bauzasyup, that I understand it's a policy11:20
ajoI guess, to make things fluid,11:20
bauzasso each port is attached to 1 or more policies?11:21
ajobauzas : 1 max11:21
bauzasand you can only get one port per VIF right?11:21
*** links has quit IRC11:21
ajobauzas, I guess (not sure what happens with containers in VMs)11:22
* bauzas played with Neutron in a very far far galaxy long time ago11:22
ajo:-)11:22
ajobauzas , how does nova get the information from the port in neutron? via API?, VIF inspection?11:23
bauzasajo: but my question is : what kind of information do you want to provide ? is that just the policy type, or a more discrete value, like the % of b/w ?11:23
ajobauzas , I don't care as long as we can make scheduling based decisions and accounting of b/w per network type11:24
ajobauzas , we could provide the policy type, and the policies11:24
bauzasajo: you have a good question that I can't answer yet11:24
johnthetubaguyajo: we keep the port information in our network-info-cache thing, basically first filled up when you create the instance and get info back from neutron on the port binding, etc, etc11:24
ajoaha11:25
bauzasajo: for the moment, it's the virt driver which reports the resources to the Resource Tracker that writes in DB11:25
johnthetubaguyajo: it would be great to get your problem written up in a nova spec, just the problem spec bit11:25
ajojohnthetubaguy , that sounds like a good idea,11:25
bauzasjohnthetubaguy: I remember some discussion on that, but since I'm pretty not network-seasoned, I missed some crucial bits11:25
*** gongysh has quit IRC11:26
ajobauzas : ack,11:26
ajobauzas , may be we could somehow use the vif plugging mechanism to exchange extra information on ports, like the bw they consume on nets11:26
ajobut, that could change in runtime,11:27
ajofor example if somebody modifies the policy11:27
johnthetubaguythe problem for me is tracking neutron resources in our resource tracker, that feels odd to me, but maybe its like SR-IOV, its a resource nova tracks and hands out to neutron on port attach/detach11:27
ajothe port limit is rised up, ... the extra / or lower bw consumption needs to be accounted.11:27
bauzasjohnthetubaguy: that was basically the stuff that was discussed during that SR-IOV session11:27
*** gcb has joined #openstack-nova11:27
johnthetubaguyajo: we already have aync updates for some things, via a call back system11:27
johnthetubaguyajo: but honestly, that sounds like it should be a resize operations, as you might need to move the instance11:28
*** exploreshaifali has quit IRC11:28
ajoyes, the complexity is making the scheduler aware of resources provided by others in the nodes (or as aggregates -jay spec-)11:28
bauzasright, I'm concerned by the conceptual issue of modifying a policy at runtime11:28
bauzaslike11:28
ajojohnthetubaguy : or block the operation at api level: "host -X cannot satisfy the new policy..."11:29
ajobauzas  ^11:29
bauzasimagine that your port is enforcing a very low quality constraint like it is at the moment11:29
ajothat should be the right approach, at least for a start11:29
*** sudipto has quit IRC11:29
ajobauzas , yes, I understand, you either move the instance away, or block the request because it cannot be satisfied11:29
bauzaswhat would happen if your operator suddently decides to modify it to a very strict policy?11:30
ajothen it's up to the admin, or tenant to move the instances before trying to modify the policy again11:30
bauzasthat's impacting other ports, right ?11:30
johnthetubaguyajo: that would be hard to do if its a neutron API call to change a Nova controlled resource, that sounds wrong, almost feels like it lives in the Nova flavor11:30
johnthetubaguyajo: you can't leave that stuff up to the admin or tenant, IMHO11:30
bauzasright, you could pass that information thru a flavor11:31
johnthetubaguyajo: like when a user wants more memory, we go find them it, we don't hope that overcommit will do the trick, and the admin has made room for it11:31
johnthetubaguybauzas: I am thinking keep it like SR-IOV, roughly11:31
ajojohnthetubaguy : I wasn't proposing overcommit, but , blocking the request to "ask for more resources" on the neutron side11:31
*** vladikr has quit IRC11:32
johnthetubaguyajo: now what I would love is to have neutron port flavors, and maybe map those to instance flavors (to some extent)11:32
ajojohnthetubaguy , bauzas : I agree, if we can automate migrating VMs to accomodate that, that's ideal, but I think that may need to be a long term goal, not a first implementation11:32
bauzasjohnthetubaguy: I feel the same11:32
ajojohnthetubaguy : that's remembering of my initial proposal :)11:32
ajoour neutron port flavors are the policies :)11:33

ajobut not sure if we're talking about the same thing exactly11:33
johnthetubaguyI think we need neutron port flavors regardless11:34
johnthetubaguyyeah, time for a spec to try iron things out I think11:34
ajojohnthetubaguy , what do you mean by neutron port flavors exactly?11:34
ajocan you give me an example11:34
ajojohnthetubaguy , yeah, let's stop after this one and move to a spec11:34
johnthetubaguygold, silver, bronze port flavors11:34
ajojohnthetubaguy : defined in neutron?11:34
* bauzas running out for lunch11:35
ajojohnthetubaguy : ok, we already have that, that are qos-policies = port-flavors as you define them11:35
irenabthis is exposed via nova api?11:35
*** ferest has joined #openstack-nova11:35
johnthetubaguygold is SR-IOV, silver = 10GB (shared), bronze = 1GB (shared), all defined in neutron11:35
ajook, we could have an extra abstraction11:35
ajoproviding a vnic type + qos policy11:35
ajoand that would be the flavor11:36
johnthetubaguyyou create a port of "gold" type, on network, A, and pass that into nova11:36
ajoaha, ok, but then nova is on the sames issues of accounting resources (bw)11:36
johnthetubaguythe nova flavor might then say, it needs gold ports, or support silver and bronze ports, defaults to silver, for example11:36
ajoaha11:36
irenabjohnthetubaguy: if you require port to be crearted  in advance , then no need for the additional abstraction11:37
irenabyou can create port and set everything you need, then pass to nova.11:37

ajothe scheduler may need to be aware of the qos policy details and the resources to do the right scheduling11:38
johnthetubaguythe user that wants SR-IOV just asks for that flavor, they don't need to do any PCI binding mapping themselves11:38
johnthetubaguyyes, there are lots of things still needed11:39
*** josecastroleon has joined #openstack-nova11:39
johnthetubaguybut with that layer of abstraction, it all becomes a bit easier to reason about I feel11:39
sdagueanyone else want to take a quick sanity check on gibi_'s https://review.openstack.org/#/c/240858 it has a bunch of +2s on friday, but we were holding it up for the release note11:39
*** ferest has quit IRC11:39
irenabjohnthetubaguy: Can you please clarify the user actions? I am not sure I see why currently it is not possible. If user wants SR-IOV port, he just sets vnic_type=direct11:40
irenabfor the port he creates and then passes it to nova11:40
openstackgerritAlvaro Lopez Garcia proposed openstack/nova: SameHostFilter should fail if host does not have instances  https://review.openstack.org/22903011:40
johnthetubaguyirenab: how does the user choose between two different types of SRIOV11:40
johnthetubaguysdague: ah, sweet, taking a look11:40
ajojohnthetubaguy , I think it's two types of vnic types11:41
johnthetubaguyajo: agreed, in the new model11:41
irenabwhat do you mean by different types of SR-IOV?11:41
ajoirenab , pci pass through, or tap/interface  (I'm not sure of the naming) I guess?11:42
BobBallHelp :( I'm struggling with some python 2/3 unicode fun.  In py2 I must pass a string, in py3 I must pass unicode, but it seems that sometimes in real scenarios, on py2, the string is actually already unicode (perhaps because I'm formatting with some of the substitutions already being unicode?).  How can I convert to str iff python2 and leave as unicode (which it will already be) iff py3? This is for the string argument to uuid.uuid5()11:42
irenaboperator makes the binding of the NIC to provider net11:42
irenabajo: indeed, there are 2 different vnic_types11:42
johnthetubaguyirenab: I am thinking two different vendors in the same cloud, or a macvtap vs non-macvtap, possible different base line speeds, etc, could be lots of variations11:43
irenabI am just trying to see what we gain by additional abstraction and how user (Tenant) gets fsimple way to consume it11:44
johnthetubaguythe user shouldn't be exposed to all the implementation details, when they just don't need to understand those11:44
irenabDifferent vendors may be supported via Host aggregates11:44
irenabI have dejavu of 2 years ago :-)11:44
johnthetubaguylikewise, I am saying the same thing I did two years ago, I wish we had port flavors to stop the user needing to know implementation details11:45
tangchen__johnthetubaguy, alex_xu, bauzas: hi, may I ask a question ?    Please refer to:  https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L188911:46
tangchen__johnthetubaguy, alex_xu, bauzas: I don't understand what the "regular expression matching" means here.11:47
tangchen__johnthetubaguy, alex_xu, bauzas: I think this what will be executed when we run nova list --sort key:asc11:47
*** xek has quit IRC11:47
tangchen__johnthetubaguy, alex_xu, bauzas: I can understand the exact matching. But what does the regular expression matching mean ?11:48
*** Sree has quit IRC11:49
tangchen__johnthetubaguy, alex_xu, bauzas: Does that mean when I run "nova list --sort hostname:asc", it will also sort by "host" ?11:49
*** Sree has joined #openstack-nova11:49
irenabjohnthetubaguy: so for different vendors it seems more like Host Aggregates than neutron port level to me.11:49
ajojohnthetubaguy , I agree port flavors would be a good thing in general, I have a better understanding of what you mean now, although it's a different issue from what I was trying to fix, it's related, and it's worth spending time on it11:50
johnthetubaguytangchen__: have you read this bit of the code: https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L204711:50
*** tdurakov has joined #openstack-nova11:50

tangchen__johnthetubaguy: I didn't go deeper into that function. I think it is something related to sql.11:55

bauzasdansmith: to see whether we have it running15:32
dansmithbauzas: ah, well, this is a requirement for landing the grenade patch to make this actually happen15:32
sdaguemdbooth: it's in nova/test.py15:32
mdboothsdague: Thanks. Wasn't sure if it was in nova or a library.15:32
sdaguebauzas: I approved the CI patch15:32
sdaguemdbooth: https://github.com/openstack/nova/blob/876679c08f05eaa2a90b1f053b65b78a0af433df/nova/tests/fixtures.py#L167-L19315:33
bauzassdague: yup, ty https://review.openstack.org/#/c/242027/15:33
markus_zdansmith: If a review has a "UpgradeImpact" keyword in its commit message, should this patch then also include a change for the release notes?15:33
mriedemmarkus_z: yes15:33
sdagueit's actually using a base feature of fixtures, and we have our own fixture to setup the way we want it15:33
dansmithmarkus_z: apparently.. I'm not up on all the plans for reno usage15:33
bauzasmriedem: mriedem: we can decouple the reno change from the implementation patch, but that should be in a series15:34
markus_zmriedem: Is "UpgradeImpact" then obsolete, since the note is part of the patch set?15:34
*** ihrachys has joined #openstack-nova15:34
dhellmanndansmith, markus_z : any time you would have done something to ensure a release note went into the wiki, you should now add a note using a reno input file instead15:34
mdboothsdague: Cool. As a secondary issue to the oslo.messaging thing last week, I'm curious why the timeout was at 160 seconds rather than 60 seconds.15:34
mriedemmarkus_z: i'd say if the reno change is in the same change, then we don't need the tag15:34
mriedembauzas: i'd prefer to see them in the same change15:34
*** pratikmallya has quit IRC15:34
bauzasmriedem: having the reno file in the same patch makes a backport a bit hard I guess - although we shouldn't backport something with an UpgradeImpact tho :15:34
mriedemjust like docs updates for the hypervisor support matrix, else we forget about them15:34
bauzas:D15:35
mriedembauzas: right15:35
mdboothsdague: In redesigning the patch, I might look at ways of making it more kill friendly.15:35
markus_zmriedem: Yepp, makes sense to keep it in the same patch15:35
*** ljxiash has joined #openstack-nova15:35
dhellmannbauzas : having the reno file in the patch with the code *is the point of using reno* for backports :-)15:35
dansmithmriedem: I feel like the reno patch can't always be exactly with all the things affecting the release note, but whenever possible it makes sense to me15:35
sdaguemdbooth: I don't know historically why it's 16015:35
bauzasdhellmann: mriedem: okay, I rally the consensus :)15:35
markus_zdhellmann: Cool, great to see the tighter coupling of change to release note.15:35
dhellmanndansmith : reno files can be edited after the original patch, too15:35
sdaguebut that's the value in .testr.conf15:35
markus_zI like that15:35
dansmithdhellmann: sure, but not all patches will translate to a single line in the release note15:36
mriedemdansmith: if it's a single change bug fix it should be in the same change, if it's a bp series that runs all cycle, then sure it goes at the end15:36
dansmithmriedem: right, exactly15:36
mdboothsdague: Ah, ok. In that case there's no issue, I guess. I thought it was messing with the timeout somehow.15:36
dhellmanndansmith : sure, I just meant if something is left out of the note, that doesn't require a new note15:36
bauzasmriedem: +115:36

markus_zedleafe: sure, go ahead17:44
edleafethere was no such OptGroup in the current scheduler/manager.py17:44
edleafeI didn't want to change anything, just move it17:44
edleafeAre OptGroups required now to work?17:45
markus_zedleafe: No, they are not required.17:45
*** paul-carlton has joined #openstack-nova17:45

*** klkumar has quit IRC17:46

openstackgerritDan Smith proposed openstack/nova-specs: Enable SR-IOV physical functions assignment with Neutron port  https://review.openstack.org/23987517:48
edleafemarkus_z: so moving forward, should we avoid changing as much as possible? Or add groupings where there aren't any?17:48

edleafemarkus_z: no, I meant adding OptGroups where there aren't any in the current code17:50
johnthetubaguymarkus_z: I was looking at the config change, and wondering if we should just do the straight move, then do the updates?17:51
markus_zjohnthetubaguy: You mean splitting it up? patch1: move opts, patch2: update help?17:52
johnthetubaguymarkus_z: edleafe: like the idea of move being really simple, with basically zero test changes, then following up with fix ups once the file is full17:52
johnthetubaguymarkus_z: yeah, its tempting to recommend that17:52
johnthetubaguymarkus_z: would that be reasonable? or is that making for way too much work17:53
johnthetubaguymarkus_z: I am just thinking, the move should be quite a simple review, and it leaves the arguments around text on the second change17:53
markus_zjohnthetubaguy: It's reasonable. I wanted to keep the amount of patches low.17:53

dansmithmriedem: hmm, some other completely different fails.. let me look at those first22:41
jwcroppesuro-patz: ok, so the data in the DB is correct22:41
jwcroppesuro-patz: (which is also the same data that is sent out via the message queue for recipients like Ceilometer)22:41
suro-patzjwcroppe: that's what I mentioned, the issue is in reading the data from DB as object22:42
mriedemdims: we'd block in g-r so we can block in nova, if we need to22:42
mriedemdoesn't matter if it's only nova22:42
suro-patzjwcroppe: we are trying to read a float as Integer and thus losing the data most of the time given the type of the data and the normalization22:42
*** otter768 has joined #openstack-nova22:43
jwcroppesuro-patz: ok, yep... so the code reading the data is busted.  That makes sense.22:43
suro-patzjwcroppe: cool!22:43

suro-patzjwcroppe: Whenever you have time, if you can chime into the review, it would be great …22:43
jwcroppesuro-patz: yeah, I will do that.  thanks for catching this... looks like the effects of the original bug had a few other tentacles out there22:44
suro-patzas jpipes: also was referring to the earlier check-in of https://github.com/openstack/nova/commit/87e1d8fab2b5888e711f07001025600fe709aaa722:44

suro-patzjwcroppe: trying to understand your comment better - is not the proposed patch modifying to read it as float, and avoid truncation?22:56

mriedemjaypipes: https://review.openstack.org/#/c/246013/22:56
*** jeblair has joined #openstack-nova22:56
dansmithsuro-patz: you just need an obj_make_compatible() that converts that field to an integer if the desired version is less than the version in which you bumped it22:56
dansmithsuro-patz: I haven't read the rest of your patch, but that's what needs to be done for the version side of it22:56

melwittdansmith: why don't we need to do the mock and MyObj for the other TestRemoteObject tests test_minor_version_less and test_revision_ignored?23:01
suro-patzdansmith: obj_make_compatible() change applies for the software with higher version. On writer() this change has no impact - so obj_make_compatible() won't have any impact. On reader(), the conversion to integer will re-enforce the bug itself. So does not gain us much, unless I am missing something23:01
dansmithmelwitt: because of why they fail I think23:01
*** toure has joined #openstack-nova23:02
dansmithmelwitt: I'm going to follow up and remove MyObj2, which will force me to hit any of those remaining tests23:02
*** med_ has joined #openstack-nova23:02
dansmithsuro-patz: it doesn't matter, you have to write the compatibility routine if you bump the object23:02

*** haomaiwa_ has joined #openstack-nova23:02
melwittdansmith: okay, so this is just targeting the ones that are affected as part of the bug23:02
dansmithmelwitt: yeah, the bug is that that override wasn't in place in the fixture, but it tickled those other tests23:03
suro-patzdansmith: it is hard to write code, which is NOP :)23:03
dansmithsuro-patz: it should be trivial23:03
suro-patzdansmith: I know it is trivial, but if it has no impact or usefulness, should we add it? That's the question I have23:04
*** beekneemech has joined #openstack-nova23:05
dansmithsuro-patz: if you send that object to an older node and don't have the routine, it will crash. end of story.23:05

suro-patzdansmith: If version A views a field of an object as Int, and version A+1 has the field as float, you mean node with A will crash on receiving an object from a node (A+1)? I expect truncation and wrong interpretation of value. But I am trying to understand how would it crash …23:09
*** lifeless has joined #openstack-nova23:09
*** lucasagomes has joined #openstack-nova23:09

suro-patzdansmith: I see - from your explanation it seems all the values are read/written as literal/string, which explains why it would crash. Otherwise, int(1.0) works fine23:13

*** edmondsw has joined #openstack-nova23:13
*** pkholkin has joined #openstack-nova23:13
dansmithsuro-patz: it has nothing to do with reading and writing from the database, it has to do with RPC communication and the serialization that comes with that23:14
*** sacharya has quit IRC23:15
dansmiththe field type determines how it is serialized and deserialized, so if you define it as an int and then pass it something non-integer-like, it'll explode23:15
