| 21:33:20 | sean-k-mooney | spatel: you shoudl also look into http://erlang.org/doc/man/HiPE_app.html | |
| 21:35:15 | openstackgerrit | Merged openstack/nova master: Handle neutron without the fip-port-details extension https://review.opendev.org/705760 | |
| 21:38:42 | spatel | sean-k-mooney: i am using hugepage | |
| 21:38:52 | spatel | I have tried all possible best practices | |
| 21:39:56 | spatel | earlier i gave all CPU to vm (32 core) so thinking i should just create VM with 16 vCPU so it stay one side of NUMA zone to see how its performing.. | |
| 21:42:30 | sean-k-mooney | ya numa affinitising the vm might help or create a dual numa guest | |
| 21:42:56 | sean-k-mooney | that would report the numa affintiy to erlang but if you are using hugepags it has a numa toplogy of 1 already | |
| 21:43:03 | spatel | I am only curious if i run same benchmark on bare metal then i get good result but if i run on VM then it gives poor result | |
| 21:43:16 | sean-k-mooney | what it could be is the cpu model | |
| 21:43:34 | sean-k-mooney | if you are not useing host-passthouhg you might not have all the cpu feature in the vm that you have in the host | |
| 21:43:36 | spatel | my CPU mode is passthrough | |
| 21:43:58 | sean-k-mooney | well if you have it numa affined and cpu passthohg | |
| 21:44:03 | sean-k-mooney | are you using cpu pinning | |
| 21:44:06 | spatel | Yes | |
| 21:44:11 | spatel | CPU pinning | |
| 21:44:27 | sean-k-mooney | then the only bottelnecs you have left are disk io or netwrok | |
| 21:44:52 | sean-k-mooney | what disk cache mode are you using | |
| 21:44:53 | spatel | I am using SR-IOV and not seeing any single packetloss or performance issue on network layer | |
| 21:45:08 | spatel | We have SSD | |
| 21:45:15 | spatel | not sure about disk cache mode? | |
| 21:45:47 | sean-k-mooney | https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.disk_cachemodes | |
| 21:46:08 | spatel | I have noticed in SS command lost of packet getting in queue and increasing latency | |
| 21:46:29 | sean-k-mooney | file=writeback,block=writeback,network=writeback would be the highest performace setting in most cases | |
| 21:48:06 | spatel | hmm | |
| 21:48:27 | spatel | I will try that too | |
| 21:48:50 | spatel | is that kvm setting ? | |
| 21:49:34 | sean-k-mooney | ya its a setting for the libvirt dirver | |
| 21:49:38 | spatel | I have flavor setting numa_node=2 | |
| 21:49:41 | sean-k-mooney | so in the [libvirt] section | |
| 21:49:58 | spatel | ok.. i will give it a try and see if that make any difference | |
| 21:50:22 | spatel | tomorrow i am going to run more erlang test and see where is the bottleneck.. i will keep you posted.. | |

| 22:44:25 | efried | gibi: stephenfin, other: how many people were in the room at the Shanghai PTG? | |
| 23:36:01 | alex_xu | efried: 20 maybe | |
| #openstack-nova - 2020-02-06 | |||
| 00:44:19 | efried | Thanks alex_xu | |
| 03:00:28 | openstackgerrit | Merged openstack/nova master: Revert "nova shared storage: rbd is always shared storage" https://review.opendev.org/682523 | |
| 03:38:39 | openstackgerrit | Qiu Fossen proposed openstack/nova-specs master: specify mac for creating instance https://review.opendev.org/700429 | |
| 05:16:14 | openstackgerrit | Brin Zhang proposed openstack/nova master: Add SYSTEM_READER role to server actions API https://review.opendev.org/706179 | |
| 06:50:59 | openstackgerrit | Merged openstack/nova master: Avoid calling neutron for N networks https://review.opendev.org/705784 | |
| 07:02:33 | openstackgerrit | Brin Zhang proposed openstack/nova master: Add SYSTEM_READER role to servers actions API https://review.opendev.org/706179 | |
| 07:53:36 | gibi | efried: yeah max 20 I t was more on the 12 - 15 side in my memory | |
| 07:54:45 | gibi | efried, dansmith: I was avoiding cyborg integration code recently as I saw that both of you are actively handled that but now I feel you want me to read in. I hope I will not blow up things with my fresh oppinion | |
| 08:04:09 | openstackgerrit | Brin Zhang proposed openstack/nova master: Expose instance action event details out of the API https://review.opendev.org/694430 | |
| 09:30:56 | ralonsoh | stephenfin, sorry for bothering you again... | |
| 09:30:57 | ralonsoh | https://review.opendev.org/#/c/705760/2/nova/network/neutron.py@2615 | |
| 09:31:12 | ralonsoh | I didn't realize this when I reviewed the patch | |
| 09:31:32 | ralonsoh | but a FIP can NOT be attached to a port | |
| 09:32:35 | ralonsoh | https://7147d7e07a0a4e67ee4e-8dbb68c995c97f9fb5b4258bb26a4c49.ssl.cf2.rackcdn.com/703537/7/check/neutron-ovn-tempest-ovs-release/7b55444/testr_results.html | |
| 09:32:35 | ralonsoh | so this exception... is unnecessary. Actually we are still having some problems in the Neutron OVN CI | |
| 09:32:48 | stephenfin | damn. okay, let me fix that up | |
| 09:33:22 | ralonsoh | stephenfin, let me first check the test | |
| 09:33:33 | ralonsoh | I would like to confirm that in the logs | |
| 09:39:08 | ralonsoh | stephenfin, https://7147d7e07a0a4e67ee4e-8dbb68c995c97f9fb5b4258bb26a4c49.ssl.cf2.rackcdn.com/703537/7/check/neutron-ovn-tempest-ovs-release/7b55444/controller/logs/screen-n-api.txt | |
| 09:39:27 | ralonsoh | we are creating IPs without any port associated | |
| 10:05:57 | stephenfin | ralonsoh: What happens if I do 'list_ports(ids=['foo'])' and 'foo' doesn't exist? | |
| 10:06:16 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Don't error out on floating IPs without associated ports https://review.opendev.org/706213 | |
| 10:06:19 | stephenfin | I assume I'll just get an empty response, i.e. {'ports': []} | |
| 10:06:34 | stephenfin | ralonsoh, gibi: That's the fix, btw ^ | |
| 10:08:19 | ralonsoh | stephenfin, yes, you have an empty list | |
| 10:08:33 | ralonsoh | show_port will return an exception | |
| 10:08:39 | ralonsoh | list_ports don't | |
| 10:08:50 | stephenfin | cool, that's what I'd assumed in that patch | |
| 10:16:51 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Rework how we check for extensions https://review.opendev.org/705792 | |
| 11:09:01 | openstackgerrit | Lee Yarwood proposed openstack/nova master: libvirt: Rename _is_storage_shared_with to _is_path_shared_with https://review.opendev.org/693337 | |
| 11:09:14 | lyarwood | stephenfin: ^ can you +W that again, had to rebase to clear the conflict. | |
| 11:09:30 | stephenfin | done | |
| 11:10:05 | lyarwood | ta | |
| 11:11:25 | gibi | stephenfin: a floating ip without a port is an unused floating ip? | |
| 11:11:55 | openstackgerrit | Guo Jingyu proposed openstack/nova-specs master: Proposal for a safer noVNC console with password authentication https://review.opendev.org/623120 | |
| 11:12:04 | stephenfin | gibi: Yup. We're using | |
| 11:13:11 | stephenfin | ...it for the 'GET /os-floating-ips' API, and that describes itself as "Return(ing) a list of floating IPs allocated to a project." | |
| 11:13:21 | gibi | cool, thanks | |
| 11:24:34 | openstackgerrit | Stephen Finucane proposed openstack/nova-specs master: Re-propose "Secure Boot support for KVM & QEMU guests" for Ussuri https://review.opendev.org/693844 | |
| 11:25:45 | brinzhang | gibi, lyarwood: this is my spec's invalid link fix patch https://review.opendev.org/#/c/705933/, please review | |

| 11:27:19 | brinzhang | gibi, lyarwood: https://review.opendev.org/#/q/status:open+project:openstack/nova+branch:master+topic:bug/1663456 this is the bug 1663456 fix, one is +2 by stephenfin | |
| 12:09:25 | openstackgerrit | Brin Zhang proposed openstack/nova master: Add server actions v82 samples test https://review.opendev.org/706251 | |
| 12:16:49 | gibi | stephenfin: fyi if you need I can reproduce the stestr bug https://github.com/mtreinish/stestr/pull/285 in a pretty stable way in nova | |
| 12:17:53 | stephenfin | gibi: I had this https://review.opendev.org/#/c/700522/ | |
| 12:31:22 | gibi | stephenfin: you won :) | |
| 12:31:38 | gibi | stephenfin: is there a way I can help the stestr fix merged? | |
| 12:34:05 | artom | stephenfin, left you a drive-by comment on https://review.opendev.org/#/c/705792/3 | |
| 12:37:12 | openstackgerrit | Arnaud Morin proposed openstack/nova master: Force refresh of instance info cache on event https://review.opendev.org/702394 | |

| 13:07:30 | kashyap | stephenfin: Thanks for taking time to address your own nits here! https://review.opendev.org/#/c/693844/ | |
| 13:08:00 | kashyap | stephenfin: For future, don't worry about it. I don't consider it "tedious" to adddress reviewer's feedback (and yours fall "within reason" almost always) :-) | |
| 13:08:55 | kashyap | Appreciate it regardless. Ah, I see that in some places I've used single back ticks instead of the double back ticks | |
| 13:15:45 | gibi | efried: I cannot join to the today's nova meeting as I have a F2F meeting at the same time | |
| 13:51:04 | stephenfin | gibi: Other than annoying mtreinish and lifeless, probably not :) | |
| 13:51:12 | gibi | :) | |
| 13:51:48 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Rework how we check for neutron extensions https://review.opendev.org/705792 | |
| 13:51:57 | stephenfin | artom: oh yeah, done | |

| 13:54:08 | brinzhang | stephenfin: hi, I have a question with the cmd.test_policy, https://github.com/openstack/nova/blob/master/nova/tests/unit/cmd/test_policy.py#L119 | |
| 13:55:17 | efried | gibi: specifically for that one patch the important thing was seeing how the steps taken to extract device profiles and convert them into resource requests correspond to the same steps for bandwidth resources. | |
