| 07:38:00 | gmann | pooja_jadhav: and the sample file path you changed ? | |
| 07:39:38 | pooja_jadhav | gmann: I am adding sample files inside https://github.com/openstack/nova/tree/85b36cd2f82ccd740057c1bee08fc722209604ab/nova/tests/functional/api_sample_tests/api_samples/os-simple-tenant-usage/v2.40 | |
| 07:40:26 | pooja_jadhav | and passing use_common_server_api_samples=False to _post_server() method so that, It will get the samples from api_samples/os-simple-tenant-usage/v2.40 only. | |
| 07:43:33 | gmann | pooja_jadhav: that's all you are doing perfectly | |
| 07:44:51 | pooja_jadhav | gmann: yes, I will try my best for this. If anything u think I am missing something then please let me know. :) | |
| 07:46:07 | gmann | pooja_jadhav: ok, but if you can push WIP patch up then it will be easy otherwise, it is difficult to debug | |

| 08:55:58 | tssurya | sean-k-mooney: good morning, around ? | |
| 08:58:11 | tssurya | its about the exception handling for the scatter utility stuff we discussed yesterday, would you be modifying your existing patch or should I put a new one for the simple approach ? asking just to rebase the series | |
| 09:08:56 | gmann | pooja_jadhav: seems like you need to override the nova.volume.cinder.create which is not in conderFixture | |
| 09:09:12 | gmann | t i tested with that and it worked fine | |
| 09:12:02 | gmann | pooja_jadhav: i mean stub | |
| 09:13:28 | tssurya | sean-k-mooney: nvm, my bad just saw http://eavesdrop.openstack.org/irclogs/%23openstack-nova/%23openstack-nova.2018-10-03.log.html#t2018-10-03T19:17:25 | |
| 09:16:23 | sean-k-mooney | am i am actully im just making coffee | |
| 09:16:59 | sean-k-mooney | this is around the time in normally wake up and start being online | |
| 09:18:31 | sean-k-mooney | tssurya: for the simple approch we agreed to just retrun the exception by construction a new copy and leave a comment saying we are doing that because of https://www.python.org/dev/peps/pep-0344/#open-issue-garbage-collection | |
| 09:19:13 | sean-k-mooney | tssurya: so expect execption e: retrun e.class(e.args) | |
| 09:19:44 | tssurya | sean-k-mooney:ack thanks :) sorry for the early ping then | |
| 09:19:56 | tssurya | I was calculating 1hr from behing here | |
| 09:20:19 | tssurya | 1hr behind the time in CEST I mean | |
| 09:20:33 | sean-k-mooney | haha no worries. i shift my day to give me more overlap with the us also im not a morning person :) | |
| 09:21:34 | tssurya | I'll put something up then for the spec's usecase and add you as a reviewer :) | |
| 09:21:37 | tssurya | thanks again | |
| 09:29:27 | sean-k-mooney | bauzas: are you online? | |
| 09:33:05 | bauzas | sean-k-mooney: I am, but I'll need to get my daughters in 10 mins | |
| 09:33:36 | sean-k-mooney | no worries we can chat when you get back its about vgpus | |
| 09:36:11 | bauzas | sean-k-mooney: ok, for what ? | |
| 09:36:59 | sean-k-mooney | i want to know how libvirt/nova detect something is a gpu | |
| 09:37:15 | sean-k-mooney | also i have some good news for you | |
| 09:37:47 | bauzas | sean-k-mooney: we don't really detect whether it's a gpu | |
| 09:38:07 | bauzas | sean-k-mooney: we just say "heh, look, there are some pci devices that support mdevs" | |
| 09:38:10 | sean-k-mooney | bauzas: mnaser: is amazing and is going to provide 1-2 vm instance with gpus for testing in the gate https://review.openstack.org/#/c/607686/ | |
| 09:38:22 | bauzas | cool | |
| 09:38:30 | bauzas | so I could write a functional test | |
| 09:38:42 | sean-k-mooney | bauzas: ok that is a bug but also cool because i think i konw how to fake them in the gate also | |
| 09:38:54 | bauzas | sean-k-mooney: what's a bug ? | |
| 09:39:03 | bauzas | to say a pci device supporting mdevs is a gpu ? | |
| 09:39:12 | sean-k-mooney | nic and acclerator can expose mdevs | |
| 09:39:13 | bauzas | sure, but we have a spec fixing this | |
| 09:40:03 | bauzas | sean-k-mooney: in this spec, you explicitly say which PCI IDs *are* GPUs | |
| 09:40:06 | bauzas | sean-k-mooney: https://review.openstack.org/#/c/602474/ | |
| 09:40:22 | bauzas | I need to go, bbiabn | |
| 09:40:33 | sean-k-mooney | bauzas: cool that will work for the terible hack i want to do. ill let you know when you get back | |
| 09:51:10 | gmann | pooja_jadhav: hope that worked. | |
| 10:12:00 | bauzas | sean-k-mooney: just able to discuss for 5 mins | |
| 10:12:20 | bauzas | sean-k-mooney: but also, without the spec, it also only works for GPU devices | |
| 10:12:45 | bauzas | sean-k-mooney: because libvirt provides us all the mdev capable devices, but we look at which supports the provided GPU type | |
| 10:12:51 | bauzas | say 'nvidia-11' | |
| 10:13:27 | bauzas | so, in case you have mdev capable devices that are not GPU devices (say a nic one), they don't support the type | |
| 10:13:33 | bauzas | so we don't use them | |
| 10:14:03 | bauzas | also, say you have an Intel GPU not supporting the 'nvidia-11' type, then we don't have inventory for it too | |
| 10:15:06 | sean-k-mooney | ok so your assumeing good nameing of the mdev types without the spec | |
| 10:15:16 | sean-k-mooney | e.g. not small medium large | |
| 10:15:28 | sean-k-mooney | but ya i think that is fine | |
| 10:15:59 | sean-k-mooney | basically i found out that in kernel 4.16 there is a new driver called netdevsim that simulates a nic | |
| 10:16:15 | sean-k-mooney | it supprots sriov without any hardware and mdevs | |
| 10:16:41 | sean-k-mooney | so i think i can use it to test pci passhtrouhg, sriov, and other things in the gate | |
| 10:17:00 | sean-k-mooney | i also may be able to use the mdev support to pretend to be a vgpu | |
| 10:17:32 | sean-k-mooney | not sure about the last point but i was planning to look into it more for sriov testing | |
| 10:22:34 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: api-ref: Move the evacuate action to admin action https://review.openstack.org/607896 | |
| 11:46:42 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: consumer gen: support claim_resources https://review.openstack.org/583667 | |
| 11:46:43 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Enable nested allocation candidates in scheduler https://review.openstack.org/585672 | |
| 11:46:44 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Use provider tree in virt FakeDriver https://review.openstack.org/604083 | |
| 11:49:34 | gibi | jaypipes, efried: I replied in https://review.openstack.org/583667 for both of you fixed your comments. The runway slot for this patch ends today so I appreciate any feedback | |
| 11:49:42 | openstackgerrit | Surya Seetharaman proposed openstack/nova master: [WIP] Refactor scatter-gather utility to return exception objects https://review.openstack.org/607934 | |
| 11:52:29 | jaypipes | gibi: yup, on it. | |
| 11:52:41 | gibi | jaypipes: thanks a lot | |
| 11:54:17 | bauzas | sean-k-mooney: back there | |
| 11:54:25 | bauzas | sean-k-mooney: if you wanna continue to discuss... | |
| 11:54:54 | bauzas | gibi: don't worry about the runway slot, now that I'm done with the reshaper change, your series is my top prio | |
| 11:55:10 | gibi | bauzas: cool, thanks | |
| 11:55:42 | bauzas | gibi: so, the above means that I can review it, right? | |
| 11:56:46 | gibi | bauzas: it means that tha last patch of consumer gen is updated with fixes based on jaypipes and efried comments, there are patches top of that that also up to date til https://review.openstack.org/604083 I'm fixing comment in the rest as we speak | |
| 11:56:58 | bauzas | gibi: okay, will look later today | |
| 11:57:26 | bauzas | gibi: FWIW I have a machine with GPU devices so I can test most of your series | |
| 11:57:38 | gibi | bauzas: sounds cool :) | |
| 11:58:26 | gibi | bauzas: so far I relied on functional test cases. Fortunately the resource allocation handling these patches change are possible to cover with functional | |
| 11:59:21 | gibi | bauzas: the physical consumpton of VGPUs are something where my functional test case wont be enough | |
| 11:59:36 | sean-k-mooney | jaypipes: bauzas gibi so in case you missed it earlier i think i figured out a way to test pci passthough, sriov, and some other things like livemigration with the same in the gate using the netdevsim kernel module | |
| 11:59:54 | gibi | sean-k-mooney: that is really good news! | |
| 11:59:58 | bauzas | gibi: I mean, I could just test your series with my reshape change | |
| 12:00:14 | bauzas | gibi: so that I could be sure we would be able to boot a flavor asking for VGPUs | |
| 12:00:24 | bauzas | (in a nested worldà | |
| 12:00:26 | sean-k-mooney | i also think that can be hacked to pretend to be vgpus i need to investgate that futher | |
| 12:00:30 | gibi | bauzas: yeah allocate, then rehape, then allocate again is something that needs coverage | |
| 12:00:44 | bauzas | gibi: I tested all of that with my single change | |
| 12:00:49 | gibi | bauzas: cool | |
| 12:00:51 | bauzas | gibi: but of course the boot failed | |
| 12:01:00 | bauzas | gibi: since I wasn't using your series | |
| 12:01:13 | bauzas | what I could do is just to pick your series, and do the same | |
| 12:01:19 | gibi | bauzas: I assume it will work with my series included | |
| 12:01:26 | bauzas | gibi: that's my assumption too | |
| 12:01:32 | bauzas | and the functional test shows it | |
| 12:01:39 | bauzas | but a real evidence is better, I guess | |
| 12:01:45 | gibi | bauzas: totally agree | |
