22:10:51 mriedem http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22%7C%20Fatal%20Python%20error%3A%20Cannot%20recover%20from%20stack%20overflow.%5C%22%20AND%20tags%3A%5C%22console%5C%22&from=7d
22:11:35 mriedem what did we merge on april 15?
22:12:32 sean-k-mooney in oslo config. apparently droping python 35 testing
22:12:46 mriedem ...
22:12:52 mriedem why would that matter in a nova py36 job?
22:13:02 mriedem especially if an oslo.config change is unreleased for us to use it
22:13:06 sean-k-mooney i assume this is a version bump in upper constratins or a new release?
22:13:25 mriedem https://github.com/openstack/requirements/commit/a96ee0e258aafb2880149b3e25dd5959f7b37c09
22:13:31 efried sean-k-mooney: are you at the PTG through Saturday?
22:14:09 sean-k-mooney im flying there the friday before and leaving the Starday afternoon so yes
22:14:50 sean-k-mooney mriedem: oslo.config 4.11.2 came out 2 days ago
22:15:07 efried sean-k-mooney: I'm going to assert that the CI topic is one we don't need jaypipes for; and dtroyer is booked Th+Fr. So I'll set the CI topic for Saturday a.m., cool?
22:15:17 sean-k-mooney oh never mind
22:15:22 sean-k-mooney that is old
22:15:40 sean-k-mooney efried: ya that sound fine
22:15:46 mriedem we're using 6.8.1 from 2 months ago
22:16:14 mriedem i also started seeing seg faults in pip 3.6 installs yesterday, so maybe something in py36 on bionic nodes since april 15
22:18:39 mriedem https://bugs.launchpad.net/nova/+bug/1825435
22:18:40 openstack Launchpad bug 1825435 in OpenStack Compute (nova) "TestRPC unit tests intermittently fail with "'>' not supported between instances of 'NoneType' and 'datetime.datetime'"" [Undecided,Confirmed]
22:19:06 aspiers sean-k-mooney: I forgot to get your take on whether hugepages are still helpful for SEV, in terms of accounting
22:19:32 sean-k-mooney am i think they are
22:19:34 aspiers sean-k-mooney: I'm a little confused by recent discussions but I got the impression they can only be used for accounting guest RAM
22:19:42 sean-k-mooney mainly because you still have to lock the memory
22:19:48 aspiers and QEMU allocates a whole bunch of other stuff
22:20:13 sean-k-mooney yes it does for mmio/dma
22:20:42 sean-k-mooney with SEV instace there will be no oversubsription of memory
22:20:48 sean-k-mooney that is also true of hugepages
22:20:53 aspiers is it useful to only track part of what is allocated though?
22:21:10 sean-k-mooney yes which will be most of it
22:21:28 sean-k-mooney the qemu overhead is ment to be tracked using the resved meory config option
22:22:36 aspiers Yeah, that's the bit which danpb is suggesting should have an rlimit at the top /machine.slice cgroup I think?
22:22:37 sean-k-mooney or on a hugepage host its assumed you leave enough free non hugepage memeroy on the host for the os and any qemu memroy required outside of the guest ram
22:22:48 sean-k-mooney ya
22:22:50 aspiers i.e. reserving some memory for the host
22:23:01 aspiers I added some paras in the spec about this - please could you check them if you didn't already?
22:23:12 sean-k-mooney so my suggetion is still use the locked element but dont set the hard_limit
22:23:21 aspiers Yes, I already changed the spec to propose that
22:23:25 sean-k-mooney and preferably use hugepages
22:23:40 aspiers it pretty much says that too
22:23:50 aspiers Most of my recent edits were just copying your advice ;)
22:23:58 sean-k-mooney if you dont use hugepages we need to tell the operators to set the ram_allocatoin_raito to 1.0
22:24:00 aspiers but I'm not 100% sure I got it all accurate
22:24:20 sean-k-mooney ill take a look at it before the ptg
22:24:25 aspiers cool thanks
22:27:56 mriedem "'>' not supported between instances of 'NoneType' and 'datetime.datetime'" seems to be showing up in stephen's cells v1 removal series first...i'm not sure what could have introduced that
22:28:40 sean-k-mooney did we merge any of that yet
22:28:46 mriedem yes
22:32:41 sean-k-mooney maybe the instance list change
22:34:30 sean-k-mooney maybe not im wondering if we change how we are handeling the sorted list
22:35:25 sean-k-mooney we used to call self._get_instances_by_filters and now we call instance_list.get_instance_objects_sorted
22:39:24 sean-k-mooney acutly no _get_instances_by_filters just calls instance_list.get_instance_objects_sorted
22:46:00 sean-k-mooney just skimmed through the few that have merged but nothing obvious jumped out at me
22:47:34 efried sean-k-mooney: Are you particularly motivated to discuss provider yaml at the PTG?
22:47:43 sean-k-mooney no
22:48:03 sean-k-mooney i mean we can but i didnt think many people were interested
22:48:17 sean-k-mooney and im not planning to work on it in train
22:48:18 efried Right, lack of interest had put it way on the back burner for me
22:48:27 sean-k-mooney ya same
22:48:47 efried It's not something we can discuss without jaypipes, so putting it at the back of the agenda is kinda pointless. I'm just going to scrub it, k?
22:49:32 sean-k-mooney sure
22:49:47 sean-k-mooney i think we have more pressing things for Train
22:49:57 efried right
23:00:08 sean-k-mooney looking at the etherpads i dont really have much propsoed anymore
23:00:26 efried sean-k-mooney: It's not a requirement for you to have stuff on there :)
23:00:35 sean-k-mooney ya i know
23:00:36 efried besides, I think the CI topic is plenty, don't you?
23:01:08 sean-k-mooney well the ci topic was not originally my idea
23:01:55 sean-k-mooney but i ment it more as what i will like be working in trains has shifited some what so i have not really need to propose much to discuss
23:03:53 sean-k-mooney thats actully a good thing as i need to still figure out what cyborg/plaement topics i shoudl attend
23:08:24 efried sean-k-mooney: It's not a bad thing if the stuff you will be working on is well enough understood that we don't need PTG time for it.
23:08:31 efried If we could do that for everything, we wouldn't need a PTG :)
23:08:37 efried gotta run o/
23:08:49 sean-k-mooney o/
