| 17:56:21 | sean-k-mooney | it all comes down to having host noes with nested virt | |
| 17:56:28 | sean-k-mooney | and 2 numa nodes | |
| 17:57:12 | sean-k-mooney | the 2 numa nodes are optional but it used dual numa node guest too | |
| 18:06:02 | lyarwood | We shouldn't allow a cold migration from an offline compute host right? | |
| 18:06:18 | dansmith | we don't check, AFAIK | |
| 18:06:51 | lyarwood | Yeah that's what I'm seeing in the API at least | |
| 18:07:12 | lyarwood | but that's a bug right? The source compute being offline should fail the attempt right there? | |
| 18:07:24 | dansmith | well, | |
| 18:07:37 | dansmith | you could argue that for sure | |
| 18:08:58 | lyarwood | k, this is from a downstream bug report where a user has tried to migrate instead of evacuate from an offline compute and the instance gets stuck in resize_prep etc. | |

| 18:21:18 | spatel | sean-k-mooney: afternoon | |
| 18:21:32 | sean-k-mooney | o/ | |
| 18:22:02 | spatel | sean-k-mooney: i had question related horizon dashboard Overview section, its saying Active instance: 367 | |
| 18:22:20 | sean-k-mooney | yep | |
| 18:22:23 | spatel | but when i run "nova list" its saying you have 280 instance total | |
| 18:22:36 | spatel | where that 367 came from? | |
| 18:22:51 | sean-k-mooney | that is a good question | |
| 18:23:05 | sean-k-mooney | i belive it hitting the simple teant usage api | |
| 18:23:11 | spatel | does it counting deleted instance too? | |
| 18:23:24 | sean-k-mooney | so it is proably showing the total number of instaces that were launched | |
| 18:23:49 | sean-k-mooney | let me take a look a dashboard for a sec | |
| 18:24:15 | spatel | ok | |
| 18:26:04 | sean-k-mooney | so i just opend my local hoizon you are lokking at the overview seaction in the project section or admin | |
| 18:26:53 | sean-k-mooney | in the project page it should just show the active instance not deleted | |
| 18:31:19 | sean-k-mooney | spatel: you could run "openstack usage list" or openstack usage show --project <your project> and see if that say 367 | |
| 18:32:17 | sean-k-mooney | spatel: i do not have a version of horizon that has teh simple teant usage api support turned on so i just see the dashboard that show the currently active instances | |
| 18:35:11 | spatel | hold on doing it | |
| 18:36:19 | spatel | sean-k-mooney: http://paste.openstack.org/show/736782/ | |
| 18:36:29 | spatel | here you go | |
| 18:36:57 | sean-k-mooney | so you were looking at the overview in the admin section | |
| 18:37:30 | sean-k-mooney | well maybe not | |
| 18:37:56 | sean-k-mooney | 314 != 367 | |
| 18:40:54 | openstackgerrit | Dan Smith proposed openstack/nova master: Only warn about not having computes nodes once in rpcapi https://review.openstack.org/623282 | |
| 18:40:55 | openstackgerrit | Dan Smith proposed openstack/nova master: Make service.get_minimum_version_all_cells() cache the results https://review.openstack.org/623283 | |
| 18:40:55 | openstackgerrit | Dan Smith proposed openstack/nova master: Make compute rpcapi version calculation check all cells https://review.openstack.org/623284 | |
| 18:40:56 | dansmith | mriedem: ^ | |
| 18:41:34 | dansmith | mriedem: hopefully we can see the difference in just the logging, and measure the impact of the all-cells change | |
| 18:42:56 | sean-k-mooney | spatel: how many running vms does "openstack hypervisor stats show -c running_vms -f value" return | |
| 18:43:23 | spatel | running | |
| 18:45:35 | sean-k-mooney | ok so that is what you were exepcting | |
| 18:45:41 | sean-k-mooney | it should match "openstack server list -f value -c ID | wc -l" | |
| 18:45:57 | sean-k-mooney | but horizon is saying 367 | |
| 18:46:31 | sean-k-mooney | it should match "openstack server list -f value -c ID | wc -l" | |
| 18:46:34 | spatel | I have two project so i need to run that command in specific project | |
| 18:46:51 | spatel | admin not giving me any data when i run "openstack server list -f value -c ID | wc -l" | |
| 18:47:05 | sean-k-mooney | am use this one instead "openstack server list -f value -c ID --all-projects | wc -l" | |
| 18:47:45 | spatel | across all project output is "287" | |
| 18:47:55 | spatel | when i run this "openstack server list -f value -c ID --all-projects | wc -l" | |
| 18:48:08 | sean-k-mooney | ok so that will inclode shelved or error state vms | |
| 18:48:20 | spatel | possible some machine are shutdown or error stat ... | |
| 18:48:35 | sean-k-mooney | its clode enought to the running vms for hypervior state that i would get horizon may be wrone | |
| 18:49:17 | sean-k-mooney | openstack server list would include all vm except deleted instances i think by default | |
| 18:49:47 | spatel | but 367 which horizon claiming is way way out.. | |
| 18:50:14 | sean-k-mooney | yes it is | |
| 18:50:23 | sean-k-mooney | i honetly dont know why | |
| 18:50:31 | spatel | i assume its counting delete and other state also... | |
| 18:50:37 | spatel | I will open BUG :) | |
| 18:50:44 | spatel | lets see what other people chime in | |
| 18:50:47 | sean-k-mooney | spatel: it should not include deleted | |
| 18:50:56 | spatel | that is what i am thinking | |
| 18:51:24 | sean-k-mooney | out of interest what is the resulted of "openstack server list -f value -c ID --deleted --all-projects | wc -l" | |
| 18:51:38 | sean-k-mooney | is it around 80 ish? | |
| 18:53:39 | mriedem | dansmith: ack, we might get results by eod | |
| 18:53:47 | dansmith | mriedem: aye | |
| 18:54:07 | dansmith | mriedem: I just -1ed your placement client thing because I'm an ass, but I will make the change for you if you want | |
| 18:54:13 | dansmith | to make myself feel better | |
| 18:54:21 | mriedem | what assery is this | |
| 18:54:35 | spatel | sean-k-mooney: ^^ | |
| 18:54:46 | spatel | i am confused now :( | |
| 18:55:36 | spatel | Here i file bug https://bugs.launchpad.net/horizon/+bug/1807251 | |
| 18:55:36 | openstack | Launchpad bug 1807251 in OpenStack Dashboard (Horizon) "Horizon Overview summary showing wrong numbers " [Undecided,New] | |
| 18:55:56 | cdent | I imagine there is.a super upper ontology of assery | |
| 18:58:52 | sean-k-mooney | spatel: that is strange | |
| 18:59:16 | spatel | definitely bug or may be some DB cleanup stuff? | |
| 18:59:17 | sean-k-mooney | even teh other things like cpu hours are way out | |
| 18:59:27 | spatel | exactly | |
| 19:00:02 | sean-k-mooney | are they showing the same time period | |
| 19:00:03 | sean-k-mooney | 2018-11-08 to 2018-12-07 | |
| 19:01:05 | sean-k-mooney | it looks like the cli is defaulting to the last month but maybe horizon has a differnt default | |
| 19:01:13 | spatel | on Horizon dates are default set to 2018-12-05 to 2018-12-06 | |
| 19:01:21 | spatel | 24 hours period | |
| 19:01:43 | sean-k-mooney | that does not explain how horrizon is showing more usage | |
| 19:01:53 | sean-k-mooney | in fact it makes it less likely.. | |
| 19:02:29 | spatel | hmm | |
| 19:02:35 | sean-k-mooney | so ya sorry i cant really help more then that | |
| 19:06:00 | spatel | don't worry it was good help to understand that i am not crazy... | |
| 19:06:19 | spatel | i thought i didn't understand or missing something but after you confirm it seems bug | |
| 19:06:26 | spatel | anyway i have opened ticket so lets see | |
| 19:07:32 | cfriesen | sean-k-mooney: do you know if anyone has ever looked at setting IRQ affinity for PCI devices? (would only really make sense for the "dedicated" case) | |
| 19:07:52 | sean-k-mooney | i did like 4 years ago | |
| 19:08:28 | sean-k-mooney | thre are two field of tought on this either user irq blanace or whatever to afinities all irq away form the cores used by vms | |
| 19:09:00 | cfriesen | sean-k-mooney: I'm talking about for PCI-passthrough, setting the affinity to the pCPUs used by the guest | |
| 19:09:02 | sean-k-mooney | or dynamicaly affinities irqs for a vf to the vm cpus | |
| 19:10:19 | sean-k-mooney | ya i was asked to make that change a few years ago and got push back rom redhat folks on the libvirt team. | |
| 19:10:26 | sean-k-mooney | let me see if i can find that. | |
| 19:21:18 | sean-k-mooney | hum i must have been an intel only bug which aparently i cant see | |
| 19:28:02 | sean-k-mooney | cfriesen: i assume you cant see https://bugzilla.redhat.com/show_bug.cgi?id=1135668 | |
| 19:28:02 | openstack | sean-k-mooney: Error: Error getting bugzilla.redhat.com bug #1135668: NotPermitted | |
| 19:29:10 | cfriesen | sean-k-mooney: nope. :) | |
