#openstack-nova - 2017-09-12
20:59:42 mwynne yes
20:59:50 bauzas okay, that's a separate thing
21:00:07 mwynne Ah, ok. Sorry..
21:00:36 bauzas no worries, huge pages in Nova isn't tracked the same way that a regular RAM consumption
21:01:24 bauzas mwynne: https://docs.openstack.org/nova/pike/admin/huge-pages.html is the one I have in mind
21:02:03 bauzas mwynne: have you followed that and modified your flavors by mentioning the mem_page_size for the instance you want to create ?
21:02:21 mwynne yes
21:02:25 bauzas even if that's a Pike doc, the flavor thing is identical in Newton
21:02:42 mwynne Yeah, I've done that.
21:02:48 bauzas mwynne: ok, so you did that, you wanna boot an instance and you end up having NoValidHosts ?
21:03:09 openstackgerrit Merged openstack/nova master: Create allocations against forced dest host during evacuate https://review.openstack.org/499399
21:03:19 mwynne Insufficient compute resources: Requested instance NUMA topology cannot fit the given host NUMA topology
21:03:36 openstackgerrit Merged openstack/nova master: Add recreate test for evacuate claim failure https://review.openstack.org/499874
21:03:42 bauzas mwynne: I actually wonder if huge pages supports and ratios can be mixed up
21:03:53 mwynne bauzas: I deleted some unused vms and then I could spawn it.
21:04:01 bauzas in general, people using huge pages are not wanting to have overallocated instances
21:04:14 bauzas so they default ratios to 1.0
21:04:44 bauzas from what I remember about the huge pages implementation, I know we don't really care of any overallocation
21:04:57 bauzas so I wouldn't be surprised if that wouldn't fit
21:05:05 openstackgerrit Merged openstack/nova master: Add a test to make sure failed evacuate cleans up dest allocation https://review.openstack.org/499877
21:05:14 mwynne Yeah. I assumed that.. What I want to be able to do is basically this: Use heat to spin up a really big stack, consuming almost all my RAM. When I'm finished with it, just power them all off so I don't have to re-deploy each time. I was hoping that having them powered down meant I could deploy and use other vms until I want to spin them all back up again.
21:05:37 openstackgerrit Merged openstack/nova master: Remove dest node allocation if evacuate MoveClaim fails https://review.openstack.org/499878
21:06:10 melwitt mwynne: there was a bug around that but the fix was backported to newton https://bugs.launchpad.net/nova/+bug/1635367
21:06:11 openstack Launchpad bug 1635367 in OpenStack Compute (nova) ocata "Ram filter is broken since Mitaka" [High,In progress] - Assigned to Matt Riedemann (mriedem)
21:06:48 melwitt mwynne: are you using at least version 14.0.8?
21:06:59 mwynne melwitt: how can I check that?
21:07:57 mwynne melwitt: 14.0.7... Nooooooo! haha
21:08:34 melwitt mwynne: okay, hopefully if you pull down 14.0.8 it will fix your problem but I'm not 100% sure that's what's causing what you're seeing with NUMA etc
21:09:05 bauzas melwitt: oh good catch, I forgot it
21:09:22 mwynne What's the best way to update? I'm running RDO packages.
21:09:42 bauzas mwynne: just upgrade your packages if you're on a 14.0.z version already
21:09:47 bauzas and restart your services
21:10:01 mwynne bauzas: Ok. I figured.. Just wasn't sure if that would break stuff :S
21:10:04 bauzas but yeah, I just feel we don't mix up overcommits and huge pages
21:11:08 mwynne bauzas: Ok. I'
21:11:23 mwynne I'll see if updating helps. But I think you might be right about huge pages...
21:11:34 mwynne Thanks for all the help guys. I appreciate it :)
21:26:40 efried mikal FYI, https://review.openstack.org/#/c/503078/ totally doesn't work. I had a feeling... it's the difference, when we hijack the namespace, of putting our code in a new module within an existing package, versus making a new package.
21:27:14 efried mikal I suppose I could try structuring it as nova/virt/powervm/__init__.py <== with the code in (or at least exported from) here.
21:35:14 openstackgerrit Michael Still proposed openstack/nova master: Fix missed chown call https://review.openstack.org/503079
21:35:21 efried mikal (and esberglu edmondsw) we'll see if this flies: https://review.openstack.org/#/c/503078/
21:37:44 openstackgerrit OpenStack Proposal Bot proposed openstack/nova master: Updated from global requirements https://review.openstack.org/502700
21:38:44 med_ did you just find that by grep'ing for dangling chowns?
21:38:51 med_ smells that way
21:40:29 efried mikal BTW, why do we have to be in the nova.privsep namespace to make this work?
21:40:41 openstackgerrit OpenStack Proposal Bot proposed openstack/os-vif master: Updated from global requirements https://review.openstack.org/502708
21:41:57 openstackgerrit Dan Smith proposed openstack/nova master: Add nova-manage db command for ironic flavor migrations https://review.openstack.org/501025
21:55:17 mikal efried: so privsep has a check for the namespadce of escalated methods, and they _must_ be in nova.privsep
21:55:30 mikal efried: but can't you just drop a single file into that directory as part of your install process?
21:55:57 mikal efried: it stops us accidentally escalating the capabilities of some random method I suppose
21:56:07 mikal efried: but it was an oslo implementation decision two years ago
21:56:20 efried mikal Unless I figure out a way to hijack the namespace, like I'm doing :)
21:56:27 efried mikal As for dropping a file in...
21:56:32 efried That sounds really ew to me.
21:56:45 efried Unprecedented at least in our driver.
21:56:57 efried If it was a conf or something, that'd be different.
22:04:32 mikal So, there's a privsep session in the nova track. We should make sure we dig into this then.
22:05:45 mikal I've explicitly added it to the agenda
22:12:00 mriedem dansmith: +2 on https://review.openstack.org/#/c/501025/
22:12:17 bauzas I'm confused on triaging https://bugs.launchpad.net/nova/+bug/1716344, help needed
22:12:18 openstack Launchpad bug 1716344 in OpenStack Compute (nova) "Nova-API sometimes uses Keystone's public endpoint" [Undecided,New]
22:12:40 bauzas AFAICU, we get the endpoint URL by calling the service catalog, or if the service catalog is passed with the context
22:13:21 bauzas looks to me the bug is a possible misconfig, but I don't know which specific conf opt gets the endpoint to call for getting the service catalog, or where it gets that specific value
22:26:19 bauzas mriedem: looks to me a known problem, right ? https://bugs.launchpad.net/nova/+bug/1715569
22:26:20 openstack Launchpad bug 1715569 in OpenStack Compute (nova) "Live migration fails with an attached non-bootable Cinder volume (Pike)" [Undecided,New]
22:28:29 bauzas mdbooth: does the above ^ sound a bell to you ?
22:29:23 bauzas anyway, let's triage it as valid and we'll see

07:38:30 rtailor does anybody know why these three tests are failing when running with python testtools

07:38:35 rtailor nova.tests.unit.test_wsgi.TestWSGIServerWithSSL.test_two_servers
07:38:48 rtailor when I try to run it using this command.
07:38:51 rtailor python -m testtools.run nova.tests.unit.test_wsgi
07:44:02 rtailor These tests are failing with below error.
07:44:05 rtailor requests.exceptions.SSLError: HTTPSConnectionPool(host='127.0.0.1', port=35030): Max retries exceeded with url: / (Caused by SSLError(CertificateError("hostname '127.0.0.1' doesn't match either of 'localhost', 'ip6-localhost'",),))
07:46:54 rtailor alex_xu, ^^
07:47:15 rtailor I suspect this is because of urllib3 library.
