| 10:24:03 | Kevin_Zheng | So I guess after calling cyborg/neutron, nova will have filter hosts by names to get allocation candidates? | |
| 10:24:25 | Kevin_Zheng | if we have specific network/accelerator requests? | |
| 10:24:35 | tonyb | mriedem: okay I'll look over them | |
| 10:28:37 | exarr | Anyone able to tell me, if I try to create a server, and it fails for $random_reason and hits an error state - is there a good way to retry the rebuild? | |
| 10:28:48 | gibi | Kevin_Zheng: whta do you mean by specific accelerator request? | |
| 10:28:49 | exarr | (Currently I delete, and supply all the detail over again) | |
| 10:28:52 | openstackgerrit | Jianghua Wang proposed openstack/nova master: XenAPI: provide VGPU_DISPLAY_HEAD inventory in compute node https://review.openstack.org/523342 | |
| 10:29:47 | Kevin_Zheng | gibi create instances with accelerator=xxx in the flavor extra_spec | |
| 10:29:51 | Kevin_Zheng | for example | |
| 10:31:15 | gibi | Kevin_Zheng: is that xxx a type of accelerator or one given physical accelerator instance on some specific compute? | |
| 10:31:42 | Kevin_Zheng | type | |
| 10:32:31 | Kevin_Zheng | nova and cyborg will try to allocate the instance to the most suitable host | |
| 10:32:41 | Kevin_Zheng | in whatever way | |
| 10:35:12 | gibi | Kevin_Zheng: then in your example it is a VM boot case. In that case nova has to get the needed resources/traits for the accelerator either from cyborg or alternatively from flavor extra spec and include that in the GET allocation_candidate request for placement | |
| 10:35:49 | gibi | Kevin_Zheng: then placement will return candidates that satisfy both nova and cyborg related resouces | |
| 10:38:02 | Kevin_Zheng | gibi, yeah, as for now cyborg can only connect their own resource providers with nova resource providers by name, maybe the filter by hostname should be added to nova allocation candidates process together with CPU/RAM/Disk filtering? | |
| 10:41:55 | gibi | Kevin_Zheng: cyborg connect the accelerator RPs to the related compute RPs by name, then nova asks placement, where are those RPs (RP trees) that satisfy the resource request (that includes both cpu/ram/disk and accelerator resources/traits) then so placement will already only return those RP trees that can provide both cpu/ram/disk and accelerator resources. No additional filtering is needed by nova | |
| 10:42:11 | gmann_ | gibi: we are discussing job template and irrelevant files in Davin suit 4th floor, if you want to join | |
| 10:42:37 | gibi | gmann_: thanks for the heads up. on my way | |
| 10:42:58 | gmann_ | cool | |
| 10:43:24 | Kevin_Zheng | gibi got it | |
| 10:49:10 | openstackgerrit | Chris Dent proposed openstack/nova-specs master: Provide error codes for placement API https://review.openstack.org/418393 | |
| 10:53:05 | stelucz_ | Hello is there any way how to update or sync `OS-EXT-SRV-ATTR:host` and `OS-EXT-SRV-ATTR:hypervisor_hostname` properties? because `nova show` reports different hypervisor than where vm is hosted. This happened after live migration. Thanks | |
| 11:04:20 | Kevin_Zheng | Just poping to my head, since we have instance task states like networking, block_device_mapping, we might also have something for FPGA? | |
| 11:07:00 | mriedem | fpga-a-ing | |
| 11:07:08 | mriedem | accelerating | |
| 11:08:10 | melwitt | I vote for fpga-a-ing | |
| 11:08:47 | gibi | Kevin_Zheng: I think we have networking as we instruct neutron to bind ports. so the question for FPGA case is do nova needs to "bind" FPGAs? | |
| 11:10:24 | Kevin_Zheng | gibi I thought the idea is to call cyborg to do "bind" actions in nova-compute? but correct me if I'm wrong | |
| 11:11:19 | gibi | Kevin_Zheng: I'm not up to date about that part of the cyborg-nova interaction | |
| 11:12:10 | Kevin_Zheng | mridem decelerating for detach? | |
| 11:12:20 | Kevin_Zheng | :) | |
| 11:15:53 | Kevin_Zheng | gibi, I think we can find it out this afternoon | |
| 11:19:49 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: Remove unused LOG variables https://review.openstack.org/546097 | |
| 11:32:30 | openstackgerrit | Matt Riedemann proposed openstack/nova master: libvirt: mask InjectionInfo.admin_pass https://review.openstack.org/526772 | |
| 11:36:35 | bauzas | Kevin_Zheng: gibi: mriedem: alex_xu: huh, just saw https://review.openstack.org/#/c/318047/6/specs/backlog/approved/fpga-use-cases.rst | |
| 11:36:58 | openstackgerrit | Murali Annamneni proposed openstack/nova master: Enables MySQL Cluster Support for Nova https://review.openstack.org/446643 | |
| 11:37:25 | bauzas | I refrain commenting here about late binding, but I just feel that's up to the compute manager to make the device available to the instance | |
| 11:37:54 | bauzas | the only thing we need to care is to make sure the host that the instance is going is having *that* accelerator | |
| 11:38:09 | mriedem | that is pretty old, and i think came up from another spec that was in cyborg that was abandoned | |
| 11:38:09 | bauzas | how the binding is done, meh to me | |
| 11:38:26 | mriedem | this https://review.openstack.org/#/c/448228/ | |
| 11:38:33 | bauzas | it's a backlog spec, I'm fine with reviewing it | |
| 11:38:37 | mriedem | i guess that's actually newer | |
| 11:38:52 | alex_xu | bauzas: thinking of the late binding, there still have dependence between nova and cyborg, since there need a way to get requested resource class from the cyborg, special with the way of neutron bandwidth | |
| 11:39:00 | mriedem | i haven't been paying attention to any of the cyborg hoopla you guys have all been talking about all day | |
| 11:39:12 | bauzas | mriedem: yeah the new one is https://review.openstack.org/#/c/508572/5/specs/proposal/cyborg-nova-interaction.rst | |
| 11:39:42 | bauzas | I'm just done with discussing about cyborg :p | |
| 11:39:48 | alex_xu | bauzas: to get rid of the dependence there should be a way to boot instance like 'nova boot --device <cyborg_accelerator_uuid> --resource-class RC_FPGA... | |
| 11:40:11 | bauzas | alex_xu: yeah, I was thinking of saying it was a pci device... | |
| 11:40:28 | bauzas | but then, you could have some usb accelerator device... | |
| 11:40:48 | alex_xu | ok~ usb accelerator... | |
| 11:41:28 | alex_xu | bauzas: if using the pci device, how to get the required pci device in Nova, for the sriov, we have API call to neutron to get the physnet | |
| 11:41:56 | alex_xu | And whatever, that sounds like we have API call to cyborg, a dependence again | |
| 11:42:47 | bauzas | alex_xu: if it's a regular PCI device, we don't call Neutron, right? | |
| 11:43:15 | alex_xu | bauzas: yes, something in the flavor extra spec, right? | |
| 11:43:17 | bauzas | https://docs.openstack.org/nova/latest/admin/pci-passthrough.html | |
| 11:43:55 | bauzas | I was thinking of something like Cyborg modifying the pci whitelist and then modify the flavors, et voila :p | |
| 11:44:40 | bauzas | keep it easy :) | |
| 11:48:12 | edleafe | bauzas: Room 665 at 2pm :) | |
| 11:48:45 | bauzas | I know the room, I was there yesterday all the afternoon :p | |
| 11:48:56 | edleafe | I'm here now :) | |
| 11:49:04 | bauzas | it's f***ing way off the other roomd | |
| 11:49:16 | bauzas | it feels like you're in another city | |
| 11:49:31 | bauzas | edleafe: I guess they're done with my face :p | |
| 11:49:49 | edleafe | bauzas: no comment :P | |
| 11:49:58 | bauzas | edleafe: just an advice, keep it secret that you work on nova or you'll be discussing about bugs :p | |
| 11:50:14 | edleafe | bauzas: already had a few placemnt discussions | |
| 11:51:28 | bauzas | edleafe: ok, I guess nothing new but how to flow the placing decision to have a fresh FPGA ? | |
| 11:51:44 | edleafe | still working on that :) | |
| 11:51:56 | bauzas | ok, I can join | |

| 11:58:18 | efried | stelucz_: Responsiveness may be spotty this week during the PTG. Is there a LP bug for this issue? If not, please open one, paying attention to the template (e.g. so we know the details of your release, environment etc.) | |
| 12:04:18 | stelucz_ | efried: Hi, no, there isn't LP bug. Probably just bad timing of some actions and migration as this didn't happen in past. I am just curious if there is some way to force update of these properties or way to edit them. | |
| 12:09:55 | efried | stelucz_: I'm afraid I don't know that answer, sorry. Perhaps an email to the openstack-dev and/or openstack-operators mailing list will get you a better (asynchronous) response this week. | |
| 12:13:42 | stelucz_ | efried: thanks a lot! | |

| 14:18:19 | omegapoint | hey, can anyone tell me what needs to happen for an instance to leave task_state SCHEDULING? i have a very odd problem, all my nova services are healthy and not reporting any warnings / errors (nothing suspicious in debug log either) but instances aren't getting scheduled. all hypervisors are up and updating their resources properly | |
