#openstack-nova - 2020-09-15
10:56:09 kashyap gibi: Hey, a random non-Nova thing :-) -- on online conferencing, I've heard really good things on this FOSS tool: 'BigBlueButton' - from the recently concluded Linux Plumbers (I didn't attend it)
10:56:19 kashyap gibi: But here's some notes from the co-organizer: https://lwn.net/Articles/817146/
10:56:31 kashyap [quote]
10:56:33 kashyap To summarize, while both Jitsi and BigBlueButton are capable video-conferencing systems, BigBlueButton appears to be a more solid and feature-complete offering. In particular, the administration features and shared whiteboard capability stand out. The free-software community often struggles to create top-quality graphical applications; here we have (at least) two of them. It would appear that
10:56:39 kashyap there is no real need to be using proprietary solutions in this area.

10:57:44 gibi kashyap: hi!
10:58:23 gibi kashyap: never heard of BigBlueButton. We tried Jitsi in the last PTG and it was good except for PRC users
10:58:27 kashyap (Although, the above is suitable for smaller, developer events, rather than big, "red carpet public conferences")
10:59:22 kashyap gibi: I see; yeah, I haven't heard of BigBlueButton either, but I just heard several good reviews about from a few Linux developers :D
11:00:41 gibi kashyap: opendev provides a jitsi service so if you are interested in bbb then the next step would be get a bbb service up somewhere (maybe in infra) and try it out
11:01:02 bauzas gibi: ack thanks
11:01:30 kashyap gibi: Ah, I didn't know that OpenDev++ provides Jitsi. Cool
11:01:46 gibi kashyap: https://meetpad.opendev.org/
11:02:44 gibi bauzas: enjoy
11:03:31 bauzas gibi: which cyclist wanna me to support ?
11:03:38 bauzas ;)
11:03:43 bauzas anyway, me goes off
11:04:07 gibi bauzas: I have no idea. I did not follow cycling sport
11:23:15 sean-k-mooney if ye want to try BigBlueBotton i can proably deploy a copy on my home cloud for ye to play around with or give ye access to it so ye can
11:23:17 sean-k-mooney https://docs.bigbluebutton.org/2.2/install.html
11:23:23 sean-k-mooney it does not seeam that invovled
11:23:50 sean-k-mooney they also have a test sight
11:23:52 sean-k-mooney https://test.bigbluebutton.org/
11:23:58 sean-k-mooney *site
11:37:20 kashyap sean-k-mooney: Cool
11:38:55 openstackgerrit Balazs Gibizer proposed openstack/nova master: Use absolute path during qemu img rebase https://review.opendev.org/739246
11:39:10 sean-k-mooney i think that prc contibutors will have the same issue with jisi or bbb
11:39:46 sean-k-mooney its a firewall issue e.g. the servers wehre its hosted are blocked by the china goverment firewall
11:40:28 sean-k-mooney so if infra ended up hosting bbb as well i doubt it would help
11:42:48 gibi sean-k-mooney: I agree ^^ we switched to zoom as it seems to be allowed in PRC
12:04:22 gibi it seems that the gate is broken due to mirror issue: 'No matching distribution found for python-designateclient===4.1.0'
12:20:47 openstackgerrit Balazs Gibizer proposed openstack/nova master: Ignore HW_CPU_HYPERTHREADING trait in named groups https://review.opendev.org/735947
12:22:57 sean-k-mooney gibi: interesting
12:23:08 sean-k-mooney should we ignore or raise an error
12:23:29 sean-k-mooney i think the flavor validation code should raise an error no?
12:23:40 gibi I can change that to an error
12:24:08 gibi I choose to ignore as alex_xu said that we will never use that trait in a named group
12:24:09 sean-k-mooney im kind of ok ignoring but when creating or updating a flavor i think the validation code should make it an error
12:24:15 sean-k-mooney so ignore where your currently ignoring
12:24:16 gibi and it made the code a lot simpler
12:24:39 sean-k-mooney well we might
12:24:53 sean-k-mooney but we dont right now
12:25:39 sean-k-mooney so the reason that HW_CPU_HYPERTHREADING was originally not ment ot be set by the virt driver
12:25:52 sean-k-mooney was if we have numa in placment you might want to treat each numa node differently
12:26:29 sean-k-mooney but when stephenfin implemented the pcpus in placment feature we chose to allow the virt driver to report it
12:26:41 sean-k-mooney whihc broke tha tuse case
12:26:52 sean-k-mooney so right now we wont use it in a named group
12:27:30 sean-k-mooney the intent was to allow the isolate policy to work by only whitelisting half the treads on the scond numa node
12:27:55 sean-k-mooney instead of having to partion you cloud into servers with hypertreading enabled and servers with it disabled
12:28:25 sean-k-mooney as i said we decided to drop that usecase
12:29:59 gibi OK. I will try to add a case to the extra_spec validation
12:30:10 gibi to reject this trait in a named group
13:03:25 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Don't age swap files in the image cache https://review.opendev.org/641093
13:30:00 openstackgerrit Balazs Gibizer proposed openstack/nova master: Reject HW_CPU_HYPERTHREADING trait in named groups https://review.opendev.org/735947
13:30:48 gibi sean-k-mooney: added an extra_spec validator ^^
13:37:14 lyarwood does anyone know how/if we are tracking the pypy mirror outage(s)?
13:38:51 sean-k-mooney gibi: cool
13:39:13 sean-k-mooney gibi: i was just wondering should we extend this to all HW_CPU traits?
13:39:43 sean-k-mooney the traits in the image are always merged into the unnamed group right
13:40:06 sean-k-mooney but for a flavor does it ever make sense to allow any HW_CPU_* trait in the named groups?
13:40:23 sean-k-mooney stephenfin: ^
13:40:59 stephenfin sean-k-mooney: Just left a comment suggesting there might be more traits of this nature to worry about
13:41:12 gibi sean-k-mooney: I did not think about that
13:41:17 stephenfin Personally, I'd have tackled this separately
13:41:50 stephenfin PS2 was good enough, IMO
13:50:12 sean-k-mooney i guess we could condier extendign this in a followup
13:52:25 sean-k-mooney by the way shoudl that bug be marked invalid. i mean it was not ment to work in named groups so its invalid but we are not blocking it so that is a bug
13:52:46 sean-k-mooney so i guess its valid but the title is a little strange
13:53:23 sean-k-mooney oh i see it worked with numbered before
13:53:48 sean-k-mooney ya its vaild then.
13:54:29 openstackgerrit Merged openstack/nova stable/train: Add note and daxio version to the vPMEM document https://review.opendev.org/750222
14:22:45 nightmare_unreal is tempest and osc-functional-devstack related to user or issue with zuul / infra ?
14:32:05 bauzas gibi: ack, good evening \o
14:41:50 openstackgerrit Stephen Finucane proposed openstack/nova master: functional: Enable real policy fixture by default https://review.opendev.org/745906
14:41:51 openstackgerrit Stephen Finucane proposed openstack/nova master: functional: Add and use 'GlanceFixture' https://review.opendev.org/745907
14:41:51 openstackgerrit Stephen Finucane proposed openstack/nova master: tests: Remove '_FakeImageService' https://review.opendev.org/745908
14:42:32 stephenfin bauzas, lyarwood: Could I ask one of you to take a look at those? ^ Ignore the line count - they're not complex :)
14:48:44 sean-k-mooney stephenfin: will the glance figure remove the need to use the fake image service stuff
14:48:52 stephenfin yup
14:49:06 sean-k-mooney cool there are like 3 differnt ways to stub glance currently
14:49:18 sean-k-mooney having one fixture for it would be nice
14:49:21 stephenfin indeed; that's pretty much the entire point of that fixture :)
14:50:14 sean-k-mooney ya in the rare case i have to care about the image i always have to first check which why is its stubbed which causes a context switch from the actual problem i was trying to solve
14:58:01 bauzas stephenfin: ack, /me clicks
15:04:08 stephenfin bauzas: ta
15:04:55 bauzas stephenfin: that's an easy one to review but I need to verify you haven't forgotten any
15:05:49 stephenfin Wise. fwiw, I simply used "ag -Q 'image.fake'" and "ag 'image import fake'" to find the imports
15:06:04 stephenfin (ag = the silver searcher, btw. Great tool)
15:21:06 openstackgerrit Stephen Finucane proposed openstack/nova master: Handle libvirt reporting incorrect 4k page quantities https://review.opendev.org/631038
15:21:07 openstackgerrit Stephen Finucane proposed openstack/nova master: Make overcommit check for pinned instance pagesize aware https://review.opendev.org/631053
15:22:22 openstackgerrit Lee Yarwood proposed openstack/nova master: DNM libvirt: Support extending locally attached rbd volumes https://review.opendev.org/752069
15:23:34 gmann brinzhang_: i will check that today
15:39:09 gmann gibi: bauzas brinzhang_ do we need to fix this in older microversion or ask users to use new microversion 2.64 or higher which already has fix - https://bugs.launchpad.net/nova/+bug/1894966
15:39:09 openstack Launchpad bug 1894966 in OpenStack Compute (nova) "Create servergroup failed with unexpected error" [Low,Confirmed]
15:40:04 gmann if we decide to fix in older microversion then we can only fix the error code from 500->400. I feel we should ask to use new microversion.
15:42:42 openstackgerrit Federico Ressi proposed openstack/nova master: Requires default python3-devel package on CentOS https://review.opendev.org/752073
16:29:38 ganso Hi Nova folks! If anyone could please take one last look at https://review.opendev.org/#/c/748533/ it already has +2 and +1 (thanks stephenfin and sean-k-mooney!)
16:34:28 sean-k-mooney oh yes :) gibi i think is done for the day. bauzas maybe you can take a look its libvirt/networking related but its relivitly simple to review
16:34:56 openstackgerrit Federico Ressi proposed openstack/nova master: Log stack trace when fails launching a defined domain https://review.opendev.org/750652
