| 08:42:11 | openstackgerrit | Jan Gutter proposed openstack/nova master: Convert vrouter legacy plugging to os-vif https://review.openstack.org/571325 | |
| 09:01:00 | openstackgerrit | Adrian Chiris proposed openstack/nova master: SR-IOV Live migration indirect port support https://review.openstack.org/620115 | |
| 09:30:51 | brinzhang | +lib/placement:start_placement_api:179 die 179 'placement-api did not start' | |
| 09:31:35 | brinzhang | When I execute ./stack.sh report this error, anyone can give some help? | |
| 09:32:01 | brinzhang | this is the local.conf file on my devstack http://paste.openstack.org/show/742619/ | |
| 10:45:36 | openstackgerrit | Zhenyu Zheng proposed openstack/nova master: Per-instance serial number https://review.openstack.org/619953 | |
| 10:45:43 | Kevin_Zheng | the unstack script did not work correctly | |
| 10:45:48 | Kevin_Zheng | brinzhang | |
| 10:46:15 | Kevin_Zheng | delete all your devstack related files from site-enabled and site-availables | |
| 10:46:39 | Kevin_Zheng | after unstack | |
| 10:46:46 | Kevin_Zheng | then stack again | |
| 10:52:30 | brinzhang | Kevin_Zheng: I was unstack more than once, it always has this issue :( | |
| 10:52:51 | Kevin_Zheng | yeah, you should clean up those files manually | |
| 10:52:57 | Kevin_Zheng | before you call stack again | |
| 10:53:09 | Kevin_Zheng | files in site-enabled and site-avialable | |
| 10:53:35 | brinzhang | I don't particularly understand which files are included? | |
| 10:54:10 | brinzhang | For example the devstack folder? | |
| 10:54:13 | Kevin_Zheng | and systemd files | |
| 10:54:29 | Kevin_Zheng | check your apache2/site-enabled | |
| 11:26:28 | kashyap | time tox -e docs | |
| 11:26:53 | kashyap | Oeps, false window | |
| 11:33:21 | kashyap | stephenfin: Before I waste too much time on this, the `below <`Prerequisites`>__ hyperlink to a section in rST doesn't seem to fly :-( | |
| 11:33:27 | kashyap | The result: http://logs.openstack.org/27/629627/5/check/openstack-tox-docs/bde0494/html/admin/Prerequisites | |
| 11:33:43 | kashyap | Source on line-19: https://review.openstack.org/#/c/629627/5/doc/source/admin/secure-live-migration-with-qemu-native-tls.rst@19 | |
| 11:34:17 | stephenfin | kashyap: Ah, whoops. `below <#Prerequisites>`__ | |
| 11:34:29 | kashyap | Darn, was just reading the man page. | |
| 11:34:33 | stephenfin | kashyap: Alternatively, :ref:`below <Prerequisites>` | |
| 11:34:42 | kashyap | Yeah, read the :ref: too | |
| 11:34:50 | kashyap | It is a so subtly frustrating that it tests my stoic skills. | |
| 11:34:52 | kashyap | :D | |
| 11:35:07 | kashyap | Thank you! | |
| 11:38:11 | kashyap | stephenfin: Strange, the former (with #) didn't work; now trying the latter. | |
| 11:39:17 | kashyap | (By "didn't work", clicking on 'below' results in nothing.) | |
| 12:09:05 | kashyap | (Yep, the latter works. Most excellent.) | |
| 12:13:16 | cdent | I'm going to write a book on RST. It's going to be a compelling tale of the master and his student, staring stephenfin and kashyap . It will sell millions | |
| 12:13:30 | kashyap | Heh | |
| 12:14:23 | cdent | it will be framed as a series of vignettes | |
| 12:15:40 | kashyap | Funny you mention vingettes— | |
| 12:16:10 | kashyap | The other day when my Dutch language teacher asked for ideas for "different kinds of creative writing", I sent the idea of vignettes | |
| 12:16:50 | cdent | a worth style | |
| 12:16:55 | cdent | worthy | |
| 12:16:59 | kashyap | With an example pointing to the vignettes about "The House on the Mango Street" (the first story here: https://www.sausd.us/cms/lib/CA01000471/Centricity/Domain/457/The%20House%20on%20Mango%20Street.pdf) | |
| 12:18:23 | kashyap | cdent: But we ran out of time, we had our last class (and exam) of "level-10" yesterday. Next Monday are the results... | |
| 12:18:46 | kashyap | (But the teacher said she's going to do that vignet exercise for the next set of students.) | |
| 12:18:56 | kashyap | Although nothing is stopping me from practising it myself. | |
| 12:19:50 | cdent | good luck | |
| 12:30:51 | openstackgerrit | Kashyap Chamarthy proposed openstack/nova master: docs: Secure live migration with QEMU-native TLS https://review.openstack.org/629627 | |
| 12:31:39 | brinzhang | Kevin_Zheng: Thanks for your help, my devstack | |
| 12:31:51 | brinzhang | is ok now :) | |
| 12:36:09 | Kevin_Zheng | yw | |
| 12:50:09 | kashyap | stephenfin: Squashed all the additional into the main doc: https://review.openstack.org/629627 | |
| 12:50:33 | kashyap | Rendered version: | |
| 12:50:34 | kashyap | http://logs.openstack.org/27/629627/6/check/openstack-tox-docs/39c0a0b/html/admin/secure-live-migration-with-qemu-native-tls.html | |
| 12:50:42 | kashyap | (All the damn hyperlinks work. :D) | |
| 12:51:29 | dpawlik | kashyap: Hi, does Openstack documentation have any information, which cpu_model_extra_flags are "recommended" to enable? | |
| 12:51:51 | kashyap | dpawlik: Hi, I wrote some docuemntation for it, and linked to it as well | |
| 12:51:53 | kashyap | Let me find | |
| 12:52:08 | dpawlik | kashyap, thx | |
| 12:53:26 | kashyap | dpawlik: A couple of URLs: | |
| 12:53:37 | kashyap | (1) See slides 35 (76 of 80) here: https://kashyapc.fedorapeople.org/Effective-Virtual-CPU-Configuration-in-Nova-Berlin2018.pdf | |
| 12:53:41 | kashyap | (2) https://www.berrange.com/posts/2018/06/29/cpu-model-configuration-for-qemu-kvm-on-x86-hosts/ | |
| 12:53:50 | kashyap | (3) https://www.qemu.org/2018/02/14/qemu-2-11-1-and-spectre-update/ | |
| 12:54:16 | dpawlik | kashyap: thank you :) | |
| 12:54:24 | kashyap | (4) `grep` for "cpu_model_extra_flags" here: https://docs.openstack.org/nova/rocky/configuration/config.html | |
| 12:54:29 | kashyap | That's it. | |
| 12:56:14 | dpawlik | kashyap: I guess for now I will test just those PCID, VMX, pdpe1gb | |
| 12:56:40 | dpawlik | I was thinking that there are more of them, that are recommended | |
| 12:57:22 | kashyap | dpawlik: For Intel hosts, don't forget: "spec-ctrl", "ssbd" as well. | |
| 12:57:48 | amorin | yes | |
| 12:58:42 | dpawlik | kashyap: it will be nice to have "default suggested" features that should be enabled | |
| 12:59:02 | dpawlik | right now I just add PCID and pdpe1gb | |
| 12:59:19 | dpawlik | but about "spec-ctrl", "ssbd" i didn't know that they should be also enabled | |
| 12:59:22 | kashyap | dpawlik: That "suggestion" is not as easy as it sounds -- because that requires several checks to be done. | |
| 12:59:45 | kashyap | E.g. what host microcode you have, what host/guest kernel, what version of libvirt and QEMU | |
| 13:00:00 | kashyap | And _then_, some magic code among libvirt/QEMU should do what you have and _then_ suggest something. | |
| 13:00:29 | kashyap | We had some discussion about this with the KVM/QEMU/libvirt folks at one of the recent confereces. More details to emerge... | |
| 13:00:29 | dpawlik | wow | |
| 13:01:01 | kashyap | Until dpawlik Until then, I only have: "x86: Updating to patched vCPU models" section | |
| 13:01:04 | dpawlik | it seems like table with "which features are available in which kernel version and qemu/libvirt" | |
| 13:01:36 | kashyap | But that has to wait... | |
| 13:02:13 | dpawlik | kashyap: ack. Thanks a lot | |
| 13:02:45 | kashyap | NP. | |
| 13:26:38 | ShilpaSD | mriedem: Hi, replied to your comment and uploaded patch https://review.openstack.org/#/c/612626/2, Please give your feedback on the latest patch. | |
| 13:48:01 | openstackgerrit | Jan Gutter proposed openstack/os-vif master: Clean up versioned object backlevelling code https://review.openstack.org/630976 | |
| 13:51:34 | openstackgerrit | Maria Luisa Arches proposed openstack/nova master: Update network info during confirmed cold migration https://review.openstack.org/630978 | |
| 14:03:07 | alex_xu | will NUMACell.memory include the size of hugepages? | |
| 14:08:09 | stephenfin | alex_xu: No, it's just a basic values, i.e. what you'd get from 'cat /sys/devices/system/node/nodeN/meminfo | grep MemTotal' | |
| 14:08:13 | stephenfin | *value | |
| 14:08:22 | sean-k-mooney | actully i think it will | |
| 14:08:35 | sean-k-mooney | the memory field should be the total memory on that numa node | |
| 14:08:56 | sean-k-mooney | mem total include hugepages | |
| 14:09:43 | stephenfin | Oh, I read that directly (as in would it have information about hugepages, which is actually reported via 'NUMACell.mempages') | |
| 14:09:48 | alex_xu | I doesn't configure hugepage on my pc, so can't verify that... | |
| 14:10:10 | sean-k-mooney | one sec ill post a past bin of the output | |
| 14:10:14 | stephenfin | alex_xu: I can give you info from one of my machine, if you'd like | |
| 14:10:24 | stephenfin | Or, better yet, let sean-k-mooney do it :) | |
| 14:10:40 | alex_xu | hah, I just want an answer :) | |
| 14:10:41 | sean-k-mooney | http://paste.openstack.org/show/742643/ | |
| 14:10:58 | sean-k-mooney | so i have 64GB of ram on that numa node | |
| 14:11:06 | sean-k-mooney | Node 0 MemTotal: 65998248 kB | |
