gibithe slot for #link https://review.opendev.org/#/q/topic:bp/add-emulated-virtual-tpm will expire today16:04
gibiI don't see too much review progress lately there16:04
gibithe #link https://review.opendev.org/#/q/topic:bp/policy-defaults-refresh-deprecated-apis still has more than a week in the slot and has already a +2 so we only need a second core to push it16:04
gibithe third slot is empty16:05
gibihe next in the queue is #link https://blueprints.launchpad.net/nova/+spec/cyborg-shelve-and-unshelve but it has negative feedback and in merge conflict so I'll drop it from the queue16:05
gibithe next is #link https://review.opendev.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/provider-config-file (tony_su) which also has negative feedback16:05
gibithis might be worth to put in a slot as tony_su is actively working on it as far as I see16:06
gibior we can put the next one from the queue #link https://review.opendev.org/#/q/topic:bp/cyborg-rebuild-and-evacuate+(status:open+OR+status:merged)16:06
gibiwhat do you think?16:06
*** sean-k-mooney has joined #openstack-meeting-316:08
gibiI guess the silence means that we don't feel motivate to have anyithing in the third slot so I keep it empty for now16:08

sean-k-mooneyother then that i think 2 items is fine16:11
sean-k-mooneythe vtpm stuff is failly invovled16:11
sean-k-mooneyso there is a lot with that and the policy work as it is16:11

gibilets start with spec freeze exceptions16:18
gibi(Rambo <lijie@unitedstack.com>): Spec freeze exception for https://review.opendev.org/#/c/739349/16:18
gibiadd volume backed server rebuild spec16:19
gibiAs far as I see there is a change compared to the originally planned cinder-nova interaction16:19
rambo_liI communicated with the Cinder team, there are some questions to determine, so they will discuss this more at the midcycle next week.16:19
rambo_lihttp://eavesdrop.openstack.org/irclogs/%23openstack-meeting-alt/%23openstack-meeting-alt.2020-08-05.log.html#t2020-08-05T14:25:1616:19
gibirambo_li: do I undesrstand from the cinder meeting logs that the change from polling to os-server-externa-notification is not discussed yet?16:20
rambo_liyes, not discussed16:20
sean-k-mooneyi did not see that mentioned in the log but i could have missed it16:21
gibiI'm affraid we are running out of time for this spec on the nova side. I would only be confortable granting exception if everything would be set before end of this week16:21
gibibut I encurage to continue discussing it with cinder and nova teams16:21
rambo_liso can we approved this in nova firstly?16:23
*** yamamoto has quit IRC16:23
sean-k-mooneycinder seam to not have added a microveriosn when then added the new api16:24
gibithe question is how confident we are that cinder is OK with the external event. This is a new piece of logic that cinder needs to do16:24
sean-k-mooneyso we still have an open question of how we dedect if reimage is supported at all16:24
sean-k-mooneyeven if we went back to polling16:24
sean-k-mooneyso i think we need an api chane in any case16:25
gibisean-k-mooney: but reimage is an api change, isn't it?16:25
sean-k-mooneyyes16:25
sean-k-mooneyand when they added it16:25
sean-k-mooneythey did not add a microverion16:25
sean-k-mooneyso stien and train use the same one16:25
sean-k-mooneybut it was added in train16:25
rambo_liyes, the reimage api should add a microversion16:25
sean-k-mooneyhttps://docs.openstack.org/cinder/latest/contributor/api_microversion_history.html#maximum-in-stein-and-train16:26
sean-k-mooneyrambo_li: wasnt reimage added in trian16:26
rambo_linot merge16:26
sean-k-mooneyoh ok16:26
rambo_lihttps://review.opendev.org/#/c/606346/16:27
rambo_lithis review is add microversion16:27
rambo_liadded16:27
sean-k-mooneythen ya we just need to know if cinder are ok with the change in poling to event16:27
rambo_liyea16:27
rambo_liyes16:27
sean-k-mooneythen we can check for 2.6116:27
sean-k-mooneycan you ask the cinder team to comment on that16:28
sean-k-mooneyyou can link to the irc logs or this16:28
gibito summarize. I'm willing to grant exception if cinder confirms that they are OK with the event approach. But the deadline to approve the spec is end of this week16:28
*** psahoo has quit IRC16:28
gibiI will leave my tentative +2 vote there after the meeting16:29
rambo_lisean-k-mooney: ok, I understand16:29
rambo_ligibi: thank you16:29

gibimoving forward16:29
gibi(mlycka): Spec freeze exception for https://review.opendev.org/#/c/702810/16:29
gibiEnable REST quiescing16:30
gibithere are multiple -1 on this one16:30
gibiI see that there is discussion about using os-server-external-events for quiescing the attached volume16:30
gibior using a separate server action16:30
gibifor me this depends on the actual use case16:31
sean-k-mooneyso on irc it was mentioned that they wanted to use this without cidner16:31
sean-k-mooneyusing a third party backup solution16:31
gibiuntil now I thought that the end user would ask Cinder to snapshot a volume, and then Cinder would call Nova to quesing16:31
sean-k-mooneyyes that is wht the spec implies16:32
gibiis it supported to backup a Cinder volume without Cinder knowing about it?16:32
sean-k-mooneywell i think they are going to run somehting in the vm to do the backup16:32
sean-k-mooneywhich would be16:32
sean-k-mooneybut if they are going to the cinder backend i would say no16:33
sean-k-mooneythe same way we dont support peopel doing backup and restore of the qcow files on the compute host16:33
gibiif they go into the VM then they can also quiesce the VM from inside16:33
sean-k-mooneyyes that is true which confusted me why this was needed16:34
sean-k-mooneyif this is only for cinder then im fine with the external event16:34
gibiI think there was other things open in that spec too16:35
sean-k-mooneylast line of problem descrition "No other actor, such as an external backup tool, is able to quiesce a VM."16:35
sean-k-mooneyyes johnthetubaguy16:35
sean-k-mooneyyou had some open quetion regarding the change from the previouly appoved spec16:36
gibiI don't feel like we can answer all these during tomorrow16:36
sean-k-mooney#link https://specs.openstack.org/openstack/nova-specs/specs/mitaka/approved/expose-quiesce-unquiesce-api.html16:37
sean-k-mooneyi dont thnk so either althoguh im not really invested in this spec16:37
sean-k-mooneyoh so the previous spec give a much better usecase16:38
sean-k-mooneytakeing a snapshot fo a group of vms16:38
sean-k-mooneyand it uses an instance action16:38
gibiOK, we have to go back to the use case16:39
gibiwhich means more discussion16:39
gibiwhich means I don't think we should grant an freeze exception for this16:39
gibilet's continue discussing the use case in V and have an agreed spec for early W feels better16:40
gibisorry16:40
gibimoving on16:40
gibi(gibi): Spec freeze exception for https://review.opendev.org/#/c/73370316:40
gibiRouted network scheduling spec16:40
gibiit basically has 2 +2s16:40
gibiI was away last week so I could not approve it in time16:41
sean-k-mooneyjust to be clear this will not fix everything related to routed netwroks16:41
gibiis there any objection to approve it now?16:41
gibisean-k-mooney: yes, it is a next step forward with route net16:41
sean-k-mooneybut the issue it does fix make the situation defetly better then todya16:41
sean-k-mooneyso i think it makes sense for incremetal improvement16:42
sean-k-mooneyyep so no object from me16:42
sean-k-mooney*objection16:42

gibigoing twice16:43

gibis16:44
gibi(gibi): I will be on vacation during the next two weeks. I need volunteer(s) to run the next two nova meetings.16:44
* sean-k-mooney admires the silence16:45
gibiI will be a bit less gone than last week so I might pop in for a quick check during both weeks but not be able to run meetings16:45
gibias an alternative I can cancel the next two meetings16:45
* lyarwood can help run the next two meetings16:46
gibi\o/ thanks lyarwood !16:46
gibithen moving forward16:46
gibi(lyarwood): https://launchpad.net/~nova-coresec - Do we need to reseed this team with active core team members?16:46
lyarwoodYeah I noticed that johnthetubaguy and dansmith  are the only semi active Nova cores in that team at the moment16:47
lyarwoodand wonderd if we wanted to get more people listed there?16:47
lyarwoodgibi: I'd assume you would like to be as PTL at least?16:47
dansmithfwiw, I don't think the ptl is generally added to that list in the past,16:48
gibifor some reason I already see the private secu bugs in launchpad16:48
lyarwoodoh well there we go then16:48
sean-k-mooneygibi: if you have been added to cc you can16:48
dansmithbut it's common to copy them which makes them visible16:48
lyarwoodright TIL16:48
sean-k-mooneygibi: often the security team will add the ptl16:48
gibithen I know the reason16:48
gibiyou can corner me to help in with this work16:49
lyarwoodack thanks16:49
gibibut I would like to get a specific trigger to know where to help16:49
gibido we have any good candidate to be added to that team?16:50
gibilyarwood: are you volunteering? ;)16:50
lyarwoodhaha no I've only just been made a core16:51
lyarwoodI just wanted to raise it with the group and see if anyone was interested16:51
lyarwoodwe don't need to dwell on it, we can move on16:51
gibiOK, so if somebody interested to joint to the security team then let dansmith or johnthetubaguy know16:51
gibilyarwood: thanks for noticing and bringing this up16:52
gibithis was the last item on the agenda16:52
