| 13:26:41 | dansmith | brinzhang_: okay, after coffee | |
| 13:27:08 | brinzhang_ | dansmith: good morning ^^ | |

| 14:17:10 | sean-k-mooney | bauzas: would you have time to look at https://review.opendev.org/#/c/666914/21 and the follow up patches. it would be nice to be able to close that out. gibi maybe you could take a look to since efried_gone is nolonger here to review. since stephen an i are the author we need a non redhat person to review unless we are moving away form that requirement. alex_xu or johnthetubaguy would also work if | |
| 14:17:12 | sean-k-mooney | they are around. | |
| 14:20:29 | openstackgerrit | Lee Yarwood proposed openstack/nova master: DNM - Test TEMPEST_EXTEND_ATTACHED_ENCRYPTED_VOLUME https://review.opendev.org/707593 | |
| 14:26:36 | gibi | sean-k-mooney: ack. I cannot promise too much (have a long review queue atm) but added it to my queue | |
| 14:28:22 | gibi | sean-k-mooney: regarding the non-RH core requirement. I see this requirement as something that will be very problematic due to less diversity in the core team | |
| 14:29:59 | sean-k-mooney | gibi: ya. dont worry if you cant review but the trifect rule is likely to become a problem unless the diversity fo the core team can be restored. as someone who like that rule i would be sad to see it go but i guess we will see how it goes | |

| 14:33:16 | brinzhang_ | gmann: would like check os-instance-action policy again? https://review.opendev.org/#/c/706470/ | |
| 14:33:55 | gmann | brinzhang_: yeah, i will check after my internal meeting | |
| 14:35:22 | brinzhang_ | gmann: yeah, if it is ok, I think I can continue to do the os-instance-action (bp/action-event-fault-details) feature, there is a new policy besed on the default policy change | |
| 14:36:09 | brinzhang_ | gmann: thanks | |
| 14:37:52 | gmann | brinzhang_: yeah, you can continue on that, make dependency. | |
| 14:40:09 | brinzhang_ | gmann: Adding a default policy is only the remaining part, everything else is ready(TODO in it). So I want to do it after this done. | |
| 14:40:45 | openstackgerrit | Merged openstack/nova master: Cleanup test for system reader and reader_or_owner rules https://review.opendev.org/712515 | |
| 14:57:33 | openstackgerrit | Kevin Zhao proposed openstack/nova master: Add default cpu model for aarch64 https://review.opendev.org/709494 | |
| 14:58:48 | bauzas | sean-k-mooney: I'll try but tbh, those next weeks will be crazy | |
| 14:59:01 | bauzas | but adding it to my queue | |
| 14:59:53 | sean-k-mooney | bauzas: yep i understand just trying to see if we can complete some blueprints that are close to being done. | |
| 15:00:00 | bauzas | sure | |
| 15:01:32 | openstackgerrit | Brin Zhang proposed openstack/nova master: Add new default roles in os-instance-actions policies https://review.opendev.org/706470 | |
| 15:01:51 | kashyap | lyarwood: Hiya, hope the renewed comments make sense: forgot that we also need MIN_QEMU_BLOCKDEV | |
| 15:02:09 | kashyap | lyarwood: And a different, newer version for MIN_LIBVIRT_BLOCKDEV. (Notes in the review :)) | |
| 15:05:07 | artom | Remind me again what are the criteria for reporting a VM status as UNKNOWN? Host being down is one of them, right? | |
| 15:05:19 | artom | melwitt, ^^ if you're awake | |
| 15:05:21 | dansmith | yeah or cell down | |
| 15:05:29 | artom | dansmith, aha, ack, thanks! | |
| 15:05:42 | dansmith | it started at cell down only, but I think melwitt changed that recently | |
| 15:06:51 | artom | dansmith, that's the impression I got - not super important, just clearing out old (downstream) BZs | |
| 15:12:40 | spatel | sean-k-mooney: Good morning, if i want to disable Hyper Threading without BIOS setting how do i do that? I was reading AWS article here using offline cpu threads, do you think this is valid way to do that - https://aws.amazon.com/blogs/compute/disabling-intel-hyper-threading-technology-on-amazon-linux/ | |
| 15:14:22 | sean-k-mooney | spatel: yes you can do it via the sys virtual file system | |
| 15:14:54 | sean-k-mooney | the bios is the best way to do it as ofline cores will not unpartion the l1 cache | |
| 15:15:01 | spatel | sean-k-mooney: does that perform as good as BIOS setting ? | |
| 15:15:10 | sean-k-mooney | not quite | |
| 15:15:27 | sean-k-mooney | if you disable it in the bios it dobles the l1 cache avaiable to the core | |
| 15:15:58 | sean-k-mooney | when ht is enabled the l1 cache is partioned so the each ht has its onw region of the l1 cache | |
| 15:16:14 | spatel | We found erlang doing pretty good job when disable HT but again i don't want to do that setting from BIOS (its painful) i want to give that control to end users | |
| 15:16:41 | sean-k-mooney | but with it disable at the bios level all the l1 cache is avaiable to the physical core. at least on older intel architecutres | |
| 15:17:12 | sean-k-mooney | spatel: are you using cpu pinning | |
| 15:17:21 | spatel | Yes CPU pinning | |
| 15:17:26 | sean-k-mooney | if so you can use the cpu_thread_policy | |
| 15:17:47 | sean-k-mooney | create multiple flaovrs for the earlang instnace and let them choose | |
| 15:18:04 | spatel | sean-k-mooney: cpu_thread_policy=isolate ? | |
| 15:18:16 | sean-k-mooney | e.g. hw:cpu_thread_policy=prefer vs hw:cpu_threads_policy=isolate | |
| 15:18:20 | sean-k-mooney | yes | |
| 15:18:51 | spatel | sean-k-mooney: I have tried all kind of combination but erlang doesn't like it. | |
| 15:19:03 | sean-k-mooney | the sysfs performace delta is pretty small since normally your app/data wont fit in l1 anyway | |
| 15:19:03 | spatel | when i run VM on single NUMA perfrmance is really good | |
