#openstack-nova - 2021-02-10
12:06:36 kashyap I wrote the upstream QEMU docs for it; /me looks
12:07:50 kashyap FWIW: https://lists.nongnu.org/archive/html/qemu-devel/2020-02/msg07164.html (qemu-cpu-models.rst: Document -noTSX, mds-no, taa-no, and tsx-ctrl)
12:08:20 kashyap sean-k-mooney: So you had it off in the kernel; but the hardware supports it. But `cpuid` shows RTM true?
12:08:59 sean-k-mooney yes cpu id shows true
12:09:15 sean-k-mooney and its off in the kernel
12:11:12 sean-k-mooney http://paste.openstack.org/show/802511/
12:11:31 sean-k-mooney Skylake-Client-IBRS has it enabled
12:15:03 kashyap Yes, libvirt/QEMU introduced: "Skylake-Client-IBRS-noTSX"
12:20:02 sean-k-mooney ya so right now i do have rtm and hle in a vm on my laptop
12:21:28 sean-k-mooney with libvirt 6.1.0
13:03:51 sean-k-mooney stephenfin: requirements_cehcks is unhappy but everything else passed https://review.opendev.org/c/openstack/os-vif/+/774694
13:12:53 openstackgerrit Merged openstack/nova master: db: Compact Queens database migrations https://review.opendev.org/c/openstack/nova/+/759088
14:41:14 openstackgerrit Stephen Finucane proposed openstack/nova master: Use neutronclient's port binding APIs https://review.opendev.org/c/openstack/nova/+/706295
14:45:29 openstackgerrit Stephen Finucane proposed openstack/python-novaclient master: Add support for microversion v2.88 https://review.opendev.org/c/openstack/python-novaclient/+/770573
15:08:17 sean-k-mooney gibi: you can see nova security bug correct.
15:09:26 sean-k-mooney is there a group i can check i want to see who is on the list
15:09:28 gibi sean-k-mooney: hm, I saw some before, but then I was explicitly included in them. I think I'm not in the secu group in lauchpad
15:10:12 sean-k-mooney ah ok im being cauios with a bug im filing so im going to mark it as a security one initally but id like your input
15:10:20 sean-k-mooney ill add you to cc directly just in case
15:10:40 gibi sean-k-mooney: yes that will work
15:22:48 openstackgerrit Stephen Finucane proposed openstack/placement master: Move policy deprecation to base rules https://review.opendev.org/c/openstack/placement/+/772784
15:23:14 stephenfin gmann: I found/fixed the bug on that and am +2 on it now ^
15:24:58 stephenfin lyarwood: When you're back, would appreciate you weighing in on https://review.opendev.org/c/openstack/nova/+/751368 (stable patch)
15:26:01 gmann stephenfin: ah i see. thanks.
15:26:09 stephenfin it was so close to be perfect :D
15:26:13 stephenfin *being
15:27:34 gmann I thought we have broken something :)
15:32:44 openstackgerrit Stephen Finucane proposed openstack/nova master: cmd: Remove 'nova-manage db ironic_flavor_migration' https://review.opendev.org/c/openstack/nova/+/773776
15:33:10 stephenfin gibi: You were +2 on that previously but I'd to address a doc failure. Care to revisit? Only change is to 'doc/source/cli/nova-manage.rst' ^
15:33:20 gibi sure
15:33:24 stephenfin thanks
15:34:09 stephenfin gibi: We're _almost_ done with merging the main DB migration squash series (about time). We can probably look at removing that tweak to tox.ini once it's done, I guess?
15:35:00 gibi stephenfin: yepp, I can propose the rewert on top of the db series
15:35:10 stephenfin cool
15:44:13 openstackgerrit Stephen Finucane proposed openstack/nova master: apidb: Compact Liberty database migrations https://review.opendev.org/c/openstack/nova/+/759399

15:44:35 openstackgerrit Stephen Finucane proposed openstack/nova master: apidb: Compact Train database migrations https://review.opendev.org/c/openstack/nova/+/771420
15:44:55 stephenfin lyarwood, bauzas, melwitt: Can one of you take a look at https://review.opendev.org/c/openstack/nova/+/773727/ and https://review.opendev.org/c/openstack/nova/+/773728/ to fix the PPC64 gate, please
15:47:11 bauzas stephenfin: kinda try
15:48:04 openstackgerrit Stephen Finucane proposed openstack/os-vif master: Resolve dependency issues https://review.opendev.org/c/openstack/os-vif/+/774694
15:48:09 openstackgerrit Balazs Gibizer proposed openstack/nova master: Revert "Run the db migration tests in the same test worker" https://review.opendev.org/c/openstack/nova/+/774889
15:49:06 gibi stephenfin: here you are ^^
15:49:11 stephenfin +2
15:50:08 gibi I would keep the elastic signature still in place to see if the compaction really give us the speed bump on the gate I measured locally
15:53:48 bauzas stephenfin: https://review.opendev.org/c/openstack/nova/+/773728/ isn't needed for fixing the ppc64 gate job, righrt?
15:54:13 stephenfin bauzas: Yes, that's the crucial bit in fact
15:54:24 bauzas ok, then I misunderstood it
15:54:27 bauzas will review it
15:54:33 stephenfin http://lists.openstack.org/pipermail/openstack-discuss/2021-January/020088.html
15:55:20 stephenfin tl;dr: I added a patch to disable the USB controller if there were no USB devices in the XML, however, libvirt adds a USB keyboard and mouse automatically for guests on PPC64 hosts
15:55:40 stephenfin so it now fails
15:55:57 bauzas aha I see
15:56:16 bauzas it wants to add both the kb and the mouse but there are no longer usb controllers
15:56:21 stephenfin yup
15:56:26 bauzas gotcha, will look
15:56:41 stephenfin so we skip that logic on PPC64 now since we know we'll always need a controller on that platform
15:59:12 lyarwood stephenfin: sorry wasn't watching irc, I'll take a look at that and the other stuff from earlier after our next call
16:32:24 dansmith gibi: that's nifty, I didn't know about that grouping thing
16:33:47 dansmith gibi: did you happen to notice if the IO-related timeouts were specific to one provider?
16:34:20 dansmith tripleo was having job timeouts on one of their jobs that did a lot of IO and vexxhost switched our flavor to double the IOPs
16:35:26 gibi dansmith: the failures was spread amongst providers. at least I haven't noticed a pattern
16:35:32 dansmith okay
16:35:59 gibi I assumed it was IO limited as I was able to reproduce the extreme slowness locally if I IO deprived the machine
16:36:14 dansmith my parallel devstack ran all of those migrations in parallel for a very nice speedup on local hardware,
16:36:32 dansmith so maybe with 75% faster due to compaction we'll get a nice bump in the io-limited workers too
16:36:40 dansmith gibi: yeah probably
16:36:46 gibi yeah I saw you parallel devstack patch, that also looks like a nice bump. I will try it at some point
16:37:00 dansmith yeah, hopefully we can merge it soon
16:37:09 dansmith it's super nice to be able to stack locally in five minutes :)
16:39:39 dansmith devstack also runs db sync for keystone three times for some reason I have yet to figure out,
16:39:40 dansmith and while they don't have hundreds of migrations, it's non-trivial

17:16:37 stephenfin lyarwood: Fixed that, I think ^
17:19:50 lyarwood awesome, I'll take a look in the morning once the tests have passed
17:20:52 stephenfin ack
17:33:23 gibi dansmith: I saw ~17% speedup locally in devstack stacking with parellelism enabled. http://paste.openstack.org/show/802536/
17:33:50 gibi dansmith: two interesting observations; 1) osc time went up when run in parallel 2) unacounted time become negative :)
17:34:16 dansmith gibi: is that with the db migrations squashed?
17:34:28 dansmith merged I mean
17:34:46 gibi dansmith: squashed up until Queens
17:35:03 gibi dansmith: I will rerun now with all the db squashes
17:35:42 dansmith okay, I'm not really sure all of the component timing actually works with async because they're run in subshells and the timings don't really get reflected to the parent, AFAIK
17:36:07 gibi ahh, I see
