| 14:43:19 | efried | frickler ^^ Read down to the 20:21 mark. | |
| 14:44:34 | efried | frickler Adding your voice to the "use latest version" argument might help to get things moving in that direction \o/ | |
| 14:44:50 | frickler | efried: will do, thx for the pointer | |
| 14:45:44 | openstackgerrit | Matthew Booth proposed openstack/nova master: Make server_external_events use an optimal number of db queries https://review.openstack.org/445142 | |
| 14:45:44 | openstackgerrit | Matthew Booth proposed openstack/nova master: Add InstanceMappingList.get_by_instance_uuids https://review.openstack.org/445139 | |
| 14:45:45 | openstackgerrit | Matthew Booth proposed openstack/nova master: Add InstanceList.get_by_instance_mapping_list() https://review.openstack.org/445141 | |
| 14:45:45 | openstackgerrit | Matthew Booth proposed openstack/nova master: Add RequestContext.for_cell() https://review.openstack.org/445140 | |
| 14:52:18 | EmilienM | sdague or mriedem: can you please click on https://bugs.launchpad.net/nova/+configure-bugtracker and paste the text you use ? thanks | |
| 14:52:47 | mriedem | paste the text we use? | |
| 14:52:52 | mriedem | i don't understand the request | |
| 14:53:03 | mdbooth | mriedem: If you like my meta-test, could we re-merge https://review.openstack.org/#/c/450383/ ? | |
| 14:53:29 | EmilienM | mriedem: yes, the text that appears when someone fils a bug | |
| 14:53:34 | mriedem | mdbooth: i'm leaving in about 10 minutes so won't have time for that right now. | |
| 14:53:37 | EmilienM | mriedem: I want to re-use it in tripleo somehow | |
| 14:53:50 | mdbooth | mriedem: Ok. | |
| 14:54:01 | mriedem | EmilienM: like http://paste.openstack.org/show/604670/ ? | |
| 14:54:16 | sdague | EmilienM: is that not visible to you if you just try to open a new bug? | |
| 14:54:32 | EmilienM | mriedem: perfect | |
| 14:54:44 | EmilienM | sdague: yes but I didn't want to spam your bug tracker | |
| 14:54:54 | sdague | EmilienM: you don't have to save the bug :) | |
| 14:55:19 | EmilienM | sdague: in fact, I'm interested by the popup that appears when the bug is saved | |
| 14:55:35 | sdague | EmilienM: ah, yeh, that's another field, let me grab | |
| 14:55:42 | EmilienM | thanks a lot | |
| 14:55:51 | sdague | http://paste.openstack.org/show/604672/ | |
| 14:55:56 | EmilienM | awesome, thx again | |
| 14:56:00 | sdague | no prob | |
| 15:27:33 | mdbooth | dansmith: Did you see this change, btw: https://review.openstack.org/#/c/445142/ | |
| 15:28:10 | mdbooth | It's not incredibly important itself, although I think it's useful, but it illustrates the idea of using object contexts | |
| 15:28:18 | dansmith | mdbooth: yes, but I've been completely swamped with other stuff | |
| 15:28:36 | mdbooth | dansmith: Ok, cool. Just wondered if it had hit your radar. | |
| 15:28:45 | openstackgerrit | Sujitha proposed openstack/nova master: Adding tags field to InstancePayload https://review.openstack.org/407228 | |
| 15:39:36 | jaypipes | sfinucan: hmm, weird. for some reason I was under the impression that emulator threads would all be pinned to the same physical CPU core (when emulator thread policy was ISOLATE) | |
| 15:40:09 | jaypipes | sfinucan: since, my impression was that the emulator threads were actually pretty lightly loaded in a RT environment | |
| 15:40:53 | sfinucan | jaypipes: Not per my understanding, no - emulator cores aren't really any different to instance cores | |
| 15:41:28 | sfinucan | the only difference is that emulator cores are always on node 0 | |
| 15:41:31 | jaypipes | sfinucan: ok, no worries. just a bad recollection of mine, I guess :) | |
| 15:41:42 | sfinucan | plus how they're tracked is totally different :) | |
| 15:41:45 | sfinucan | cool cool | |
| 15:42:08 | jaypipes | sfinucan: you good on https://review.openstack.org/#/c/400877/? | |
| 15:42:18 | openstackgerrit | Maciej Szankin proposed openstack/nova master: conf: remove *_topic config opts https://review.openstack.org/433924 | |
| 15:42:52 | sfinucan | jaypipes: Hmm, don't know why I missed that. Checking now | |
| 15:57:26 | openstackgerrit | Sujitha proposed openstack/nova master: Adding tags field to InstancePayload https://review.openstack.org/407228 | |
| 15:57:51 | mriedem | lyarwood: first thing i noticed right away https://review.openstack.org/#/c/439520/ | |
| 15:59:48 | johnthetubaguy | mriedem: dam it, I -1ed for that in a previous version | |
| 16:01:10 | mriedem | sure you did, sure you did | |
| 16:01:12 | mriedem | :P | |
| 16:04:12 | mdbooth | mriedem: Incidentally, I also wanted to highlight this patch to you: https://review.openstack.org/#/c/445142/ | |
| 16:04:46 | mdbooth | As I said to dansmith, it's not that important itself, but it demonstrates using object context when you've got a bunch of instances from different cells | |
| 16:04:49 | vks1 | hi, how does nova configure tag for VM ports ? | |
| 16:05:12 | mdbooth | So as well as being less error prone, it can also be more efficient | |
| 16:05:36 | vks1 | I see for 2 ports of a network on different compute has different tag. | |
| 16:06:33 | vks1 | is this valid ? can someone point to the document for the behavior ? | |
| 16:07:29 | mriedem | vks1: you want to talk to artom | |
| 16:07:42 | mriedem | mdbooth: https://review.openstack.org/#/c/439520/ is my goal for the week | |
| 16:07:56 | artom | vks1, heya | |
| 16:08:04 | artom | vks1, I don't understand your question :( | |
| 16:08:04 | vks1 | mriedem: thanks | |
| 16:08:07 | mdbooth | mriedem: You mean the actual detach calls, right? ;) | |
| 16:08:59 | clarkb | kashyap: mdbooth: hello, right now three of the four top bugs tracked by elastic-recheck originate in libvirt http://status.openstack.org/elastic-recheck/index.html#1643911 http://status.openstack.org/elastic-recheck/index.html#1638982 http://status.openstack.org/elastic-recheck/index.html#1646779 I know kashyap has poked at these in the past, but would it be possible to try and figure out these | |
| 16:09:01 | clarkb | issues? ianw started working on getting devstack to collect core dumps (though those aren't thought to be of help here) and was going to try running libvirt under electric fence. Maybe we can get a small group of people to coordinate around this and work together? | |
| 16:09:02 | vks1 | artom: I have 2 VMs launched on 2 different compute. When I see the tap ports on OVS , on one compute I see tag:1 and on other compute its tag:3 | |
| 16:09:24 | vks1 | artom: both the VMs are of same n/w | |
| 16:09:33 | kashyap | clarkb: Hi there, I've seen yours and Ian's responses in the Inbox, but I still haven't had a chance to act on them | |
| 16:09:44 | kashyap | clarkb: Yeah, core dumps won't help in this case | |
| 16:09:58 | artom | vks1, err, you set the tags yourself at instance create? | |
| 16:10:00 | kashyap | clarkb: At least that's what the libvirt dev involved (Michal Privoznik) said | |
| 16:10:06 | vks1 | artom: no | |
| 16:10:19 | artom | vks1, err, which tags are you talking about then? | |
| 16:10:29 | mdbooth | clarkb: Couple of things, I posted an update to ianw 's patch which enables efence and also works on Fedora: https://review.openstack.org/#/c/451430/ | |
| 16:10:33 | clarkb | kashyap: ianw figured it was something devstack should do anyways so wouldn't hurt to have it, then we can actually rule it out as not being helpful | |
| 16:10:48 | vks1 | Interface "tap319bae97-0b" | |
| 16:10:48 | vks1 | tag: 1 | |
| 16:10:48 | vks1 | artom: Port "tap319bae97-0b" | |
| 16:10:49 | mdbooth | clarkb: Secondly, I think we have to treat this as a downstream Ubuntu bug | |
| 16:10:52 | mriedem | mdbooth: i want to get that refactor merged this week | |
| 16:10:56 | kashyap | clarkb: Oh that's certainly true -- having a coredump ready, it's super easy with systemd :-) | |
| 16:11:06 | artom | vks1, what is that the output of? | |
| 16:11:09 | kashyap | clarkb: I mean, having them available in general | |
| 16:11:15 | mdbooth | clarkb: The Ubuntu maintainers need to look at this | |
| 16:11:16 | clarkb | mdbooth: it certainly affects ubuntu (I don't have evidence of it affecting fedora or centos), but that doesn't necessarily mean its their bug | |
| 16:11:17 | vks1 | artom: ovs-vsctl show | |
| 16:11:20 | artom | vks1, I have a feeling you're talking about vlan ids... | |
| 16:11:27 | vks1 | artom: yeah | |
| 16:11:35 | clarkb | mdbooth: the last time we had a similar situation it was very clearly libvirts bug once someone from libvirt actually looked at it (instead of blaming ubuntu) | |
| 16:11:49 | mdbooth | clarkb: As I said in some LP bug somewhere, upstream libvirt aren't going to be that interested in this, because it's not the latest stable release | |
| 16:11:54 | artom | mriedem, you volunteered me for the wrong thing dude ;) | |
| 16:12:12 | mdbooth | clarkb: A libvirt maintainer has already looked, and doesn't think it's broken in the latest stable release | |
| 16:12:15 | mriedem | artom: redirect to vladikr? | |
| 16:12:15 | artom | vks1, so... different ports have different vlans? | |
| 16:12:28 | mriedem | artom: delegation is the sign of true leadership :) | |
| 16:12:28 | vks1 | artom: yeah | |
| 16:12:39 | artom | mriedem, *proper* delegation ;) | |
| 16:12:52 | artom | vks1, so is that bad? What's your expectation? | |
| 16:12:57 | openstack | Launchpad bug 1673483 in libvirt (Ubuntu) "libvirt: test_attach_volume_shelved_or_offload_server times out waiting for device detach (which fails)" [Medium,Triaged] | |
| 16:12:57 | kashyap | mdbooth: To answer your question from earlier in the day -- it's not actually the same bug as this one (https://bugs.launchpad.net/nova/+bug/1673483) | |
| 16:12:59 | vladikr | :) | |
| 16:13:05 | kashyap | mdbooth: Where danpb identified the missing patches | |
| 16:13:19 | vks1 | artom: thanks vladikr is here | |
| 16:13:21 | clarkb | mdbooth: ok, this is frustrating because have had had similar issues in the past with the same exact attitude from upstream and the end result was libvirt had a terrible bug in it that affected every version since the code went in | |
