13:31:41 MrRon Hello together. I wish you a wonderful day. I have a short question: Is there a plan to develop a nova-tempest-plugin in future ?
13:44:22 efried gmann: Is MrRon's question something you would know about?
13:47:23 gmann efried: MrRon : there is no plan for nova-tempest-plugin as of now. it came up before also for few scheduler filters test case. we had patch also up to add the tempest plugin for nova. I think currently there is no such case where nova tests cannot be covered with Tempest repo or nova functional test. But if there is any in future we can rethink
13:47:43 efried thanks gmann
13:52:47 cdent jaypipes: I heard a rumor you were advisining all of openstack drop RDBMS in favor of etcd!?
13:53:04 cdent \o/
13:53:38 jaypipes cdent: :)
13:53:51 jaypipes Clipper4 or FoxPro, baby!
13:54:07 cdent totes foxpro
13:54:23 jaypipes also, throw in a nice dose of CSV files for good measure.
13:54:47 jaypipes and replace configdrive with ftp
13:56:38 cdent let's do TSV files to be extra sure
13:56:46 cdent alex_xu++
13:56:48 gmann efried: MrRon https://review.openstack.org/#/c/448482/ that time, there were only scheduler test case in that list which could be covered in functional tests.
13:56:55 jaypipes alex_xu: LOL! :)
13:57:14 jangutter jaypipes, cdent: Ashton-Tate's dBASE IV, accept no substitute.
14:00:02 jaypipes jangutter: I used to use that. No joke...
14:00:29 efried jaypipes: Are you waiting for belmoreira/tssurya to spin up ironic nodes with the series at https://review.openstack.org/#/c/615677/ before reviewing?
14:00:43 jaypipes jangutter, alex_xu, cdent: pop quiz... what was Nova's original data store?
14:00:59 jangutter jaypipes: I think 90% of Apartheid-era South Africa relied on one pirated copy of dBASE III.
14:01:21 jaypipes jangutter, alex_xu, cdent: believe it or not, Redis was used as Nova's original data store.
14:01:33 jangutter jaypipes: :-O
14:01:38 jaypipes yup.
14:01:42 edleafe My first contributions to nova was removing redis
14:01:53 jaypipes edleafe: yup, I remember it well.
14:01:53 alex_xu ....what...
14:02:01 jaypipes alex_xu: yep, hard to believe, eh?: :)
14:02:10 edleafe I had an equally negative reaction when I learned that
14:02:25 jangutter jaypipes: it was a simpler time, when all Nova needed was a key-value store?
14:02:26 edleafe Hey, nova was thrown together over a weekend
14:02:26 jaypipes edleafe: and we've been data-battling ever since...
14:02:45 edleafe it worked well enough for a POC
14:03:02 jaypipes jangutter: erm, no :) it was a perfect example of how to use Redis as an RDBMS and implement JOINs in Python.
14:03:20 alex_xu jaypipes: yea...I will talk this to everyone when lunch
14:04:25 jaypipes alex_xu: here's another trivia piece for you... there is an entire copy of openwrt Linux distribution in the Nova source repository.
14:06:53 alex_xu jaypipes: yes...begin to brainstorming what is it for...
14:07:22 jaypipes alex_xu: vish added it as a way to do functional SSH testing way back when...
14:08:07 alex_xu ok, failed to guess that
14:08:11 jaypipes :)
14:10:31 mnaser rocky introduced a new way of binding ports, right?
14:10:57 mnaser i have some questions around it, possibly around failures live migrating from a queens compute to rocky compute
14:20:14 openstackgerrit Guo Jingyu proposed openstack/nova master: Add rfb.VNC support for novncproxy https://review.openstack.org/622336
14:32:46 sean-k-mooney mnaser: for live migration yes
14:33:39 sean-k-mooney mnaser: we disabled the use of multiple port bindings entirely unles neutron and both the source and dest nodes supprot it
14:34:00 sean-k-mooney mnaser: so live migrating form queens to rocky will disable all the new code
14:34:05 mnaser sean-k-mooney: i have a case of a cloud where live migrating from a queens host to rocky host results in the vm being unpingable
14:34:12 mnaser unless you restart the neutron-openvswitch-agent
14:35:04 sean-k-mooney mnaser: that is likely not related to the multiple port binding changes
14:35:28 mnaser sean-k-mooney: well in a r=>r live migration situation, i dont see it
14:35:40 mnaser and after restarting neutron-openvswitch-agent, the vm becomes pingable afterwards, its almost like something isnt properly getting wired up
14:36:12 sean-k-mooney mnaser: did you leave the vm for a period of time or just try to ping it imediatly
14:36:22 mnaser sean-k-mooney: it was on for a while, it was def dead
14:37:09 sean-k-mooney are you using conntrack security group driver or ip tables?
14:37:56 sean-k-mooney basically im wonder if ovs_hybrid_plug in the port bindings was true or false
14:38:05 sean-k-mooney that changes how the port is wired up
14:39:47 mnaser sean-k-mooney: iptables
14:39:56 alex_xu sean-k-mooney: mriedem, I give a try on the resize bug https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bug/1805767, found we miss the pci request also
14:41:09 sean-k-mooney alex_xu: yes you cannot resize to or from a flavor with a pci device alais in the extra specs
14:41:32 sean-k-mooney this is know to be broken
14:42:02 sean-k-mooney actully resize is cold migrate
14:42:08 sean-k-mooney maybe that should work
14:42:08 alex_xu sean-k-mooney: ah, cool, hope the patch fixes that
14:42:41 alex_xu sean-k-mooney: or you say there is other bug for pci in resize more than just parse the extra specs?
14:42:43 sean-k-mooney alex_xu: we know we have prolems in this areay im not sure if that one is new thinking about it
14:42:53 alex_xu ok
14:43:25 sean-k-mooney ill take a look at the patach in any case. i can see if i can test it locally
14:43:37 sean-k-mooney but it will be a few days
14:44:12 alex_xu sean-k-mooney: thanks, I tested the numa one. But still looking for a hardware for pci, not easy to test
14:44:56 mnaser https://review.openstack.org/#/q/topic:bp/neutron-new-port-binding-api
14:45:59 sean-k-mooney mnaser: so iptables means hybrid plug is true which means that os-vif plugged a veth pari into ovs and a per port liunx bridge and libvirt add the vm tap to the linux bridge on migration
14:46:27 mnaser im trying to find here the specific patch that implemented the logic which checks if the dest supports it or not, i suspect *maybe* for some reason it's thinking the other side supports it
