| 14:33:54 | rpodolyaka | I thought we defaulted to the minimum | |
| 14:34:06 | rpodolyaka | and only ask for newer version if that's needed | |
| 14:34:26 | rpodolyaka | or if the command, let's say nova show now supports it (and so does the nova-api we talk to) | |
| 14:35:51 | efried | Did nova recently change what kind of threads the compute process uses? | |
| 14:36:12 | rpodolyaka | sdague: or by latest you mean latest supported by novaclient? not the latest returned by nova-api? | |
| 14:36:43 | sdague | rpodolyaka: we default to latest novaclient understands that the server supports | |
| 14:36:55 | rpodolyaka | ah, I see, that makes sense | |
| 14:36:59 | rpodolyaka | frickler: ^ | |
| 14:37:08 | rpodolyaka | frickler: sorry for misleading you :P | |
| 14:37:25 | sdague | efried: nothing that I know of, what kind of things are you running into? | |
| 14:37:55 | efried | sdague Got an open() hanging in a subthread - and it's hanging the entire compute process. | |
| 14:38:55 | sdague | efried: there was an eventlet bump not that long ago | |
| 14:38:56 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Rename '[neutron] ovs_bridge' https://review.openstack.org/450266 | |
| 14:38:56 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Move 'floating_ips' opts into 'network' https://review.openstack.org/431039 | |
| 14:38:57 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Deprecate 'default_floating_pool' https://review.openstack.org/431038 | |
| 14:38:57 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Add neutron.default_floating_pool https://review.openstack.org/431037 | |
| 14:39:45 | efried | sdague Ah, that could do it. Got a pointer on hand, save me digging? | |
| 14:39:54 | efried | thorst ^^ | |
| 14:40:49 | efried | It's the open() in the GlanceImageServiceV2.download method. I know why it's hanging - it's opening a FIFO and the reader side hasn't been opened yet - but the problem is that it's blocking all the other threads in the process - one of which is the reader side of that fifo :( | |
| 14:41:11 | frickler | sdague: rpodolyaka: so do you happen to know why OSC behaves different? or is it just lagging behind? | |
| 14:41:11 | sdague | efried: check out the openstack dev list on some issues around poll that were found | |
| 14:41:21 | sdague | frickler: ask the osc team? | |
| 14:41:26 | efried | sdague rgr that. | |
| 14:41:37 | efried | frickler I actually ran into this same thing yesterday. | |
| 14:42:10 | frickler | sdague: efried: o.k., moving over to -sdks, thx | |
| 14:42:22 | efried | Talked about it on #openstack-sdks - let me get you an eavesdrop reference... | |
| 14:43:06 | efried | http://eavesdrop.openstack.org/irclogs/%23openstack-sdks/%23openstack-sdks.2017-03-28.log.html#t2017-03-28T17:33:58 | |
| 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: Add InstanceMappingList.get_by_instance_uuids https://review.openstack.org/445139 | |
| 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 | |
| 14:45:45 | openstackgerrit | Matthew Booth proposed openstack/nova master: Add RequestContext.for_cell() https://review.openstack.org/445140 | |
| 14:45:45 | openstackgerrit | Matthew Booth proposed openstack/nova master: Add InstanceList.get_by_instance_mapping_list() https://review.openstack.org/445141 | |
| 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 | vks1 | mriedem: thanks | |
| 16:08:04 | artom | vks1, I don't understand your question :( | |
| 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 | artom: Port "tap319bae97-0b" | |
| 16:10:48 | vks1 | tag: 1 | |
| 16:10:48 | vks1 | Interface "tap319bae97-0b" | |
