sfinucanjaypipes: Comments left on that but you might be able to answer of the top of your head: can you hotplug SCSI devices?13:31
jaypipessfinucan: you mean virtual SCSI devices?13:32
sfinucanyup13:32
sfinucanmaybe hotplug is the wrong term13:32
jaypipessure, you can attach/detach scsi block devices.13:32
sfinucanOK, so my comment on that is whether always incrementing this unit parameter when attaching a scsi device is a good idea13:33
sfinucanI'd imagine if we attach/detach a few times on a long-running VM, we'd hit that 256 device limit?13:33
sfinucan...but maybe it's a YAGNI kind of thing13:34
jaypipessfinucan: I think the whole max(unit) logic prevents that, no?13:34
*** mvk has joined #openstack-nova13:34
sfinucanjaypipes: not really. If every device gets max(unit) + 1, then we could eventually hit 257, right?13:35

sean-k-mooneyjaypipes: o/ since your about just wanted to run something past you regrading the traits api. what would your opipion be on extending traits to allow tag that are key value pairs with stardadised keys? e.g. standardised  HW_CPU_FREQUENCY key with  integer or string value field15:02
jaypipessean-k-mooney: I would be opposed to that.15:02
sean-k-mooneyok good to know :)15:02
jaypipessean-k-mooney: what would the CPU frequency be used for w.r.t. scheduling?15:03
mriedemjaypipes: alex_xu: that reminds me, something that came up in shenzhen last week, and i'm sure there is a reason for it, but why don't we allow traits on resource provider aggregates?15:03
mriedemwe have talked about a distance trait on an aggregate15:03
mriedemfor affinity15:03
jaypipesmriedem: because the aggregates are simply groups of resource providers. they aren't things in and of themselves.15:03
*** thorst has quit IRC15:04
mriedemok this question was coming from some guys doing baremetal, i'm not exactly sure what the use case was though, so i'd have to follow up15:04

jaypipessean-k-mooney: I think that kind of things is probably best left as a custom trait that you decorate a provider with.15:06

mdboothsfinucan: Here's a fun patch if you've got time: https://review.openstack.org/#/c/462521/ . It has 2 dependencies which are stacked above it.15:42
mdboothThe idea is to automatically kick off a revert if it fails on the destination. It's a bit tricky basically because of instance state, migration state, and quotas.15:43
mdboothIt's obviously a user-friendly feature, but it's actually intended as a workaround for a bug we can't easily fix right now due to our datamodel.15:44
mdboothBug details are in the bug link, but basically if your resize fails on the destination node, your instance is using a deleted glance image, and you don't revert within 24 hours, it'll delete the only remaining copy of your image. At this point your instance is unrecoverable.15:45
mdboothIdeally we would have the image cache not delete the image in this case, but our datamodel means it's not possible to identify an instance which is awaiting confirmation on the destination.15:46

mdboothHowever, resize_instance is where it's at16:36
mdboothsfinucan: The issue in resize_instance is that you've cast the control flow to another host, but after that's happened you've still got this rogue context manager which might yet futz with your state16:36
mdboothThere are no circumstances where you want that to happen16:36

mdboothsfinucan: The only you just posted16:37
mdbootherrors_out_migration16:37
mdboothAnd that's directly relevant to the following patch, and why it's a dep16:38
sfinucanah, gotcha16:38
sfinucanso 'finish_revert_resize' is the marginal change16:38
sfinucanbut 'resize_instance' is not16:38
mdboothYeah, I could potentially ditch that bit of the diff16:38
sfinucanyeah, you might drop that or at least split it. Just lets me reason about it a little easier16:39
*** yamamoto has quit IRC16:39
mdboothThe important one is resize_instance, because it does a cast16:39
mdboothSo allowing the context to continue is a race16:40
sfinucanmdbooth: You're referring to the call to finish_resize, yes?16:40
mdboothsfinucan: Yes16:40

claudiubmriedem: hello. i have a question. so there is a patch that basically sanitizes the instance object in the InstanceMetadata ( https://review.openstack.org/#/c/478991/3/nova/api/metadata/base.py ), which will get rid of the instance's context, which will make unset attributes no longer loadable. Do we have an alternative solution to this, rather than touching the lazy-loading attributes?17:10
claudiubIMO, that can be very error-prone.17:10
mriedemclaudiub: i wasn't aware of that change, but i remember that we hit some issues with metadata api with multiple cells so fail to lazy-load correctly anyway; the commit message says this isn't the long-term strategic solution,17:15
mriedemso i think long-term we want to whitelist what we store and cache17:16
mriedembecause we've had other bugs where we can't cache the instance object using things like memcache because it uses pickle and things in there don't pickle correctly, like the sqlalchemy db connection stored in the context, as noted in the commit message17:16
mriedemyeah that's what the bug was, i remember this bug https://bugs.launchpad.net/nova/+bug/169466617:16
openstackLaunchpad bug 1694666 in OpenStack Compute (nova) "metadata service PicklingError: Can't pickle <class 'sqlalchemy.orm.session.Session'> when using memcached" [Medium,Fix released] - Assigned to Dan Smith (danms)17:16
claudiubwell, can't the db connection be recreated after the pickle?17:17
openstackgerritClaudiu Belu proposed openstack/nova master: Hyper-V: fix live migration with CSVs  https://review.openstack.org/38044817:18
mriedemclaudiub: maybe, probably depends on what that's needed for17:18
mriedemclaudiub: i'm assuming you guys have extra fields on the instance object for hyperv and you need to lazy-load stuff for the metadata api?17:18
*** crushil_ has quit IRC17:19
*** tonyb has joined #openstack-nova17:19
claudiubyeah, we need the device_metadata field when we create the instance config drive, but that's not really a niche field. it's a basic field needed for the config drive17:19
*** brad[] has joined #openstack-nova17:19
mriedemhmm, have you talked to artom?17:20
mriedembecause i'd think libvirt needs the same thing17:20
*** lyan has quit IRC17:21
claudiubmriedem: so, the reason why it worked for libvirt is because libvirt always touches that instance.device_metadata field, while we only set it whenever we have device tags to set in it.17:21
mriedemah17:22
mriedemclaudiub: have you reported a bug?17:22
claudiubwhile we can also always touch it, this isn't a driver specific issue, we shouldn't have to touch it17:22
mriedemsure,17:22
mriedemi think it's an oversight in dan's patch17:22
mriedemi left a comment in there17:22
claudiubwell, i think we can simply reopen the same bug, and post a comment on launchpad about the new issue.17:23
mriedemclaudiub: it should be a new bug17:23
mriedemotherwise LP tracking gets confusing17:23
claudiubi see. ok then. i'll open up a new bug17:24
*** lyan has joined #openstack-nova17:24
mriedemit's also an unfortunate change in another way, in that obj_load_attr for these will pull the entire instance for each entry and join on another table, it would be nicer to do those all at once with expected_attrs,17:24
mriedembut maybe don't mix those issues together17:25
mriedemit could be optimized for sure though17:25
claudiubyeah, that would be nicer.17:25
claudiubmriedem: also, regarding hyper-v generation 2 vms CI testing, it is in the plan, but the main issue is that we have to test both generation 1 and generation 2 VMs, as they are both currently supported. While more and more OSes are supported on generation 2, it's still not all.17:27
*** sambetts is now known as sambetts|afk17:28
claudiuband the way the VMs are built is quite different too, especially when it comes to attaching volumes / disks, setting boot order, nic hot plugging, and other new features.17:30
*** rajathagasthya has quit IRC17:31
claudiubanyways. planning to have some coverage in the ci for gen 2 by the end of pike.17:31
mriedemclaudiub: if the majority of users are gen2, then i'd just run the ci on gen217:36
mriedemwe could always put something in the docs that since pike the hyperv CI is running against gen2 and that's the recommended configuration17:36

*** zzzeek has quit IRC19:48
jangutterLemme grab the patch set.19:48
*** zzzeek has joined #openstack-nova19:48
jaypipesjangutter: PCI devices do not get allocated by os-vif. They are allocated by the resource tracker when a launch instance request is received that includes a PCI device request.19:48
jangutterYep, that I understand.19:49
*** slaweq has joined #openstack-nova19:49
jaypipesjangutter: the resource tracker has a PCI device manager inside it, and it's that that does the actual "allocation" of a PCI device to a guest19:49
jangutterBut does it just pick _any_ available PCI address?19:49
*** kristian__ has quit IRC19:49
jangutter( https://review.openstack.org/#/q/topic:ovs_acc )19:50
jaypipesjangutter: it picks any available PCI address that matches the PCI device request that is received from the conductor.19:50
jaypipesjangutter: are you wondering who creates that PCI device request? :)19:50
*** kfarr has quit IRC19:51
jangutterYep, remember, I had the brain-dead idea of putting it into neutron-api bits.19:51
jaypipesjangutter: well, there's still quite a bit of Neutron API that is used to construct the PCI device request.19:51
jaypipesjangutter: and that existed before your idea ;)19:52
jaypipesjangutter: what moshele's patch did on the os-vif side was simply create a specialized VIF type class for the "new" OVS_ACCELERATED vif type. That vif type is something that still needs to be created in Neutron and supplied to the nova boot request by passing in a port_id value that corresponds to the pre-created Neutron port that has the port binding information indicating it's an "OVS_ACCELERATED" port.19:53
jangutterYep, that I got.19:54
*** thorst has joined #openstack-nova19:54
*** thorst has quit IRC19:54
jangutterVery similar to what happened in our patch: but the OVS_ACCELERATED vif is new.19:54
jaypipesjangutter: new in Neutron, yeah?19:55
jangutterOh, hang on. Does it auto-allocate because of VIFHostDevice ?19:57
jaypipesjangutter: what do you mean by "auto-allocate"?19:57
