#openstack-nova - 2020-02-14
20:54:07 artom spatel, OK, so try `isolate`, see if there's an improvement
20:54:10 spatel and i want to create single VM on single compute (want to assign all resources to vm)
20:54:52 spatel artom: i am reading all other document and they are saying for performance use policy=require it will make sure your process stay with sibling..
20:55:04 spatel trying to understand this language
20:55:40 artom spatel, "The presence of an SMT implementation like Intel Hyper-Threading can boost performance by up to 30% for some workloads. However, thread siblings share a number of components and contention on these components can diminish performance for other workloads."
20:55:51 artom spatel, there's no magic answer, it depends on the workload
20:56:19 spatel hmm!
20:56:48 spatel Just FYI - i am running "qemu-kvm-ev-2.12.0-33.1.el7_7.4.x86_64" hope this version is fully stable
20:57:33 artom Presumably it is, if you got from your OS's regular repos/sources
20:57:58 artom But I'm not a qemu developer, so I don't know off the top of my head (and qemu developers themselves probably don't)
21:32:13 abaindur hello, seeing an issue with SRIOV. When we delete a VM, it's VF is released back, but then we see the VF running DHCP. This causes the VF to get assigned an IP and change default route out of the host, screwing things up
21:32:52 abaindur Dont know if this is openstack related, or NIC driver related, or some Linux setting
21:34:04 abaindur Jan 30 16:36:44 compute-02 systemd: Starting DHCP interface eth40...
21:35:30 abaindur NetworkManager is disabled... and the physical NIC for the VFs has NM_CONTROLLED=no and BOOTPROTO=none

12:55:35 sean-k-mooney bauzas: gibi by the way rather then adapt the exitisting filter to work on allocation candiates we might actully want to a seperate filtering laywer that works on allocatgion candiates before the existing filters
12:56:10 gibi sean-k-mooney: that could be an alternative
12:56:30 sean-k-mooney that would avoid needing to pass an addtional paramater to all the filters so we wont break out of tree filters by changing the interface
12:56:37 gibi sean-k-mooney: it has a trade off to change the order of the filters as then NTF would run before any other filter
12:57:10 gibi but the such order just affects scheduling performance not scheduling result
12:57:32 sean-k-mooney im suggesting we leave the NTF unchanged and add a new one but yes the oder does affect performance
12:57:38 sean-k-mooney *order
12:58:16 sean-k-mooney you could put the new filter after the exstiing onece i guess
12:58:37 sean-k-mooney the NTF normally should go at the end of the existing list anyway
12:58:45 sean-k-mooney so maybe that would make more sense
12:59:42 sean-k-mooney so prefilters->placemnt->currnent filters->allocation candiate filters->weighers?
13:01:49 gibi sean-k-mooney: yeah, NTF tend to be at the end of the list so having the ac filter at the end would be closer to todays behavior
13:02:31 sean-k-mooney from an information gain point of view the host based fileter have the potentail to eliminate multipel allocation candiates by removing the host
13:02:40 sean-k-mooney so i think it makes sesne for them to come after too
13:02:52 bauzas sean-k-mooney: well, let's discuss this during the implementation
13:03:00 sean-k-mooney ya we can
13:03:17 sean-k-mooney i was just wondering if we could avoid breaking out of tree filters
13:03:27 sean-k-mooney which i think this would allow

13:20:09 gibi stephenfin: do you have some ideas why jsonutils fails while json does not in https://review.opendev.org/#/c/703133 ?
13:20:55 stephenfin have you got a traceback?
13:21:28 gibi stephenfin: sure, give me a sec
13:21:51 gibi stephenfin: http://paste.openstack.org/show/789642/
13:22:21 gibi stephenfin: are nova uses old oslo.serialization that is not py37 compatible?
13:23:11 sean-k-mooney it would seam that we are mixing byte and text strings somehwere
13:23:22 sean-k-mooney but this would have broken on py3.5
13:23:33 sean-k-mooney so its not a py 3.7 thing
13:26:56 gibi sean-k-mooney: right. but the combination for byte and str seems to happen in codecs which is stdlib
13:27:23 sean-k-mooney right so we are expecting to pass in a string
13:27:36 stephenfin gibi: looking at the source, it seems we attempt to decode whatever file we get to utf-8
13:27:37 sean-k-mooney and its expecting bytes?
13:27:46 stephenfin but I don't know why that's no okay
13:28:06 sean-k-mooney you mean https://github.com/openstack/oslo.serialization/blob/master/oslo_serialization/jsonutils.py#L255-L276
13:28:20 stephenfin at meetings for the day but I'll take a look over the week
13:37:16 stephenfin bauzas: You think you could take a look at this today? https://review.opendev.org/#/c/662522/
13:41:14 bauzas stephenfin: ok, will look today
13:57:06 gibi hm. If I change the test to load the content of the file first and then call jsonutils.loads() then it works
13:57:09 gibi with open(schema_file) as f:
13:57:11 gibi data = f.read()
13:57:14 gibi schema = jsonutils.loads(data)

15:21:10 openstackgerrit Brian Rosmaita proposed openstack/nova master: Reject boot request for unsupported images https://review.opendev.org/707738
15:23:35 artom So I guess something Fedora-specific is wrong with the stable/queens func tests?
15:24:01 artom Because locally I don't get the same failure as https://storage.bhs.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_c05/707887/1/check/nova-tox-functional-py35/c05109a/testr_results.html
15:34:53 rosmaita alex_xu: gmann: need your opinion on whether https://review.opendev.org/#/c/707738/ will require a microversion bump
15:38:46 sean-k-mooney artom: the functional tests should not be os specific nor should any of the other tests really
