| 11:35:57 | sfinucan | johnthetubaguy, pkoniszewski, owalsh: ^ | |
| 11:43:56 | openstackgerrit | Lee Yarwood proposed openstack/nova master: encryptors: Switch to os-brick encryptor classes https://review.openstack.org/391597 | |
| 11:45:35 | openstackgerrit | Bryan Song proposed openstack/nova master: Migrate VMs failed when anti-affinity group was removed from VMs. https://review.openstack.org/451664 | |
| 11:50:45 | EmilienM | hey folks, this patch is really critical for TripleO CI to run correctly again: https://review.openstack.org/#/c/456227/ | |
| 11:51:04 | openstack | Launchpad bug 1682001 in tripleo "[promotion] nova hypervisors/detail fails when host is not mapped to any cell" [Critical,In progress] - Assigned to Oliver Walsh (owalsh) | |
| 11:51:04 | EmilienM | https://bugs.launchpad.net/tripleo/+bug/1682001 | |
| 11:57:33 | openstackgerrit | Ghanshyam Mann proposed openstack/nova master: Use plain routes list for flavors-extraspecs endpoint instead of stevedore https://review.openstack.org/456585 | |
| 12:07:51 | openstackgerrit | NidhiMittalHada proposed openstack/python-novaclient master: Nova volume-attach doesn't care for device name https://review.openstack.org/454048 | |
| 12:09:05 | peter-hamilton | johnthetubaguy: if you have any further questions on the cert validation spec just ping me | |
| 12:09:43 | johnthetubaguy | peter-hamilton: cool, I should hit that one now | |
| 12:14:22 | johnthetubaguy | peter-hamilton: do we want to return a 400 error when a user gives us a list of certs, but our cert checking is turned off? | |
| 12:16:23 | peter-hamilton | johnthetubaguy: good question; does it make sense to throw a warning and store the certs with the instance anyway? | |
| 12:17:00 | johnthetubaguy | peter-hamilton: I am bit worried the user would assume the cloud has done the verification, but it hasn't actually done it | |
| 12:17:04 | peter-hamilton | johnthetubaguy: that way cert validation could be enabled at a later date and boot would still work? | |
| 12:17:42 | johnthetubaguy | although we do allow folks to specify the cert list when the image doesn't require verification anyways | |
| 12:17:52 | johnthetubaguy | its probably more consistent to just log a warning | |
| 12:18:05 | johnthetubaguy | I mean the user doesn't see that I guess | |
| 12:18:08 | peter-hamilton | johnthetubaguy: i could go either way i think | |
| 12:18:16 | johnthetubaguy | peter-hamilton: honestly, me too | |
| 12:18:43 | johnthetubaguy | wonders which side of the fence to sit | |
| 12:18:54 | peter-hamilton | johnthetubaguy: should we hash this out during implementation? | |
| 12:19:35 | johnthetubaguy | peter-hamilton: thats probably the right call | |
| 12:20:17 | peter-hamilton | johnthetubaguy: i'll make a note of it for when i get to the API patches | |
| 12:26:30 | openstackgerrit | Ghanshyam Mann proposed openstack/nova master: Use plain routes list for flavors-access endpoint instead of stevedore https://review.openstack.org/456589 | |
| 12:31:43 | openstackgerrit | Yasufumi Ogawa proposed openstack/nova-specs master: Merge "Libvirt options for DPDK" https://review.openstack.org/456593 | |
| 12:43:59 | dane-fichter | johnthetubaguy: Can you take a look at peter's spec when you get a chance? https://review.openstack.org/#/c/357151/ | |
| 12:44:12 | peter-hamilton | dane-fichter: he's already on it :) | |
| 12:44:18 | johnthetubaguy | dane-fichter: yeah, have thinking through that now :) | |
| 12:44:25 | dane-fichter | oh lol sorry | |
| 12:44:39 | johnthetubaguy | no problem, its the right day to chase me down :) | |
| 12:44:53 | openstackgerrit | Bryan Song proposed openstack/nova master: Migrate VMs failed when anti-affinity group was removed from VMs. https://review.openstack.org/451664 | |
| 12:47:14 | peter-hamilton | johnthetubaguy: awesome, thanks for the +2! | |
| 12:48:06 | johnthetubaguy | peter-hamilton: no problem, glad we are getting there, its a good feature folks need! | |
| 12:48:18 | peter-hamilton | johnthetubaguy: i agree :) | |
| 12:48:27 | peter-hamilton | johnthetubaguy: now, where is jaypipes... | |
| 12:49:12 | johnthetubaguy | hopefully he is having a coffee, putting on his flip flops, and about to open his laptop | |
| 12:57:40 | openstackgerrit | Yasufumi Ogawa proposed openstack/nova-specs master: Merge "Libvirt options for DPDK" https://review.openstack.org/456601 | |
| 13:01:04 | johnthetubaguy | sean-k-mooney: sfinucan: any chance we could get use cases added in here quickly? https://review.openstack.org/#/c/361140 | |
| 13:01:37 | johnthetubaguy | sean-k-mooney: sfinucan: something to describe the scenario(s) where each type of behaviour is what you want | |
| 13:01:37 | sfinucan | johnthetubaguy: Sure. Gimme 10 | |
| 13:02:12 | johnthetubaguy | sfinucan: sweet, I have got all confused after re-reading them, particular around the good points cdent raised in there | |
| 13:06:33 | sfinucan | johnthetubaguy: Dumb question, but is there another name of the service that boots a VM other than 'nova-compute'? | |
| 13:07:13 | johnthetubaguy | sfinucan: hmm, duno really, n-cpu? | |
| 13:07:19 | sfinucan | i.e. we'd say "the scheduler" rather than 'nova-scheduler' | |
| 13:07:30 | johnthetubaguy | "the compute node" gets used a bit | |
| 13:07:37 | johnthetubaguy | or host | |
| 13:07:51 | johnthetubaguy | or just "in compute" | |
| 13:08:03 | johnthetubaguy | not sure thats a good thing though | |
| 13:09:01 | sfinucan | maybe I should just use nova-compute and nova-scheduler consistently instead | |
| 13:14:17 | johnthetubaguy | sfinucan: I guess thats always clear | |
| 13:17:12 | bauzas | sfinucan: if you talk about a running service having a RPC MQ, it's nova-compute | |
| 13:17:25 | bauzas | sfinucan: if you talk about an hypervisor, it's a node | |
| 13:37:04 | peter-hamilton | jaypipes: if you have any questions on cert validation just ping me | |
| 13:37:28 | jaypipes | peter-hamilton: will do. was on PTO yesterday. catching up today. | |
| 13:38:55 | mriedem | johnthetubaguy: as you probably saw i marked up your remove scope check patch, let me know if you want to talk about it | |
| 13:39:32 | johnthetubaguy | mriedem: so I didn't see that, looking now | |
| 13:39:41 | mriedem | you might want to sit down | |
| 13:40:02 | johnthetubaguy | funny you say that, I just adjusted my desk to sit down mode | |
| 13:45:07 | artom | For tagged attach, I need to invalidate the metadata API's cache - however, as far as I can tell, its cache is just a dict local to that process. | |
| 13:45:42 | artom | I'm trying to thinking of a good way to solve that, without suddenly requiring all deployment to run memcache.' | |
| 13:46:07 | bauzas | jaypipes: in case you have some brain time free, I'd love to get your insights on https://review.openstack.org/#/c/450122/15 | |
| 13:46:53 | bauzas | jaypipes: my biggest concern is how a virt driver can return a single dict for a common RC if it has two distinct devices behind it | |
| 13:47:04 | bauzas | unless it's not really a problem and then meh. | |
| 13:48:04 | mriedem | artom: i wonder if we could set a flag in the db to signal when the cache should be dumped | |
| 13:48:30 | mriedem | and only look it up when requesting a version new enough for the tagged attach stuff, | |
| 13:48:37 | mriedem | although i think with config drive that would be every time | |
| 13:48:38 | artom | mriedem, it's not in the DB anywhere... | |
| 13:48:47 | mriedem | artom: i know | |
| 13:48:52 | openstackgerrit | Stephen Finucane proposed openstack/nova-specs master: PCI NUMA Policies https://review.openstack.org/361140 | |
| 13:48:59 | sfinucan | johnthetubaguy: & | |
| 13:49:03 | mriedem | artom: is the cache per instance? | |
| 13:49:11 | mriedem | i'm not terribly familiar with this | |
| 13:49:13 | artom | mriedem, I think it's per process | |
| 13:49:14 | johnthetubaguy | sfinucan: cool, queued it | |
| 13:49:14 | artom | https://github.com/openstack/nova/blob/master/nova/cache_utils.py | |
| 13:49:32 | sfinucan | Also: cdent, sean-k-mooney, snikitin_, sgordon - https://review.openstack.org/361140 | |
| 13:49:45 | sfinucan | I went with required, preferred and legacy | |
| 13:49:57 | artom | mriedem, the metadata handler calls get_client(), which, depending on conf, configures a cache region in a certain way | |
| 13:50:32 | artom | It's using dogpile.cache, in which a region is basically a frontend/client: https://dogpilecache.readthedocs.io/en/latest/usage.html | |
| 13:50:38 | sfinucan | jaypipes: You don't get to escape either :P https://review.openstack.org/361140 | |
| 13:51:07 | cdent | ha | |
| 13:51:11 | artom | And I think the backend is basically a dict: https://github.com/openstack/oslo.cache/blob/master/oslo_cache/backends/dictionary.py | |
| 13:51:50 | artom | So unless the REST API request just happened to land on the same process that eventually handles the metadata request, we need some form of IPC | |
| 13:52:44 | mriedem | artom: default cache is just in-memory per process dict? | |
| 13:52:51 | mriedem | i think it's dogpile yeah? | |
| 13:52:59 | artom | mriedem, that's what I gather, yeah | |
| 13:55:02 | mriedem | well this is a sticky wicket | |
| 13:55:19 | mriedem | we have to look up an instance when it's not cache, or the cache is expired | |
| 13:55:48 | mriedem | i was thinking we could have set a flag in instance_extra that would tell metadata api to refresh the cache, but that defeats the purpose because you have to do the db lookup to find out | |
| 13:56:26 | mriedem | default cache expiration is 15 seconds right? | |
| 13:56:48 | snikitin_ | sfinucan: wow. Thank you for update! btw 'legacy' looks good because this behavior it really a little bit strange | |
| 13:56:57 | mriedem | does the guest need to see the tagged block device immediately? | |
| 13:57:10 | artom | mriedem, ah, you're saying just wait it out? | |
| 13:57:13 | frickler | mriedem: regarding your ML question, johnthetubaguy has a patch up to clarify things: https://review.openstack.org/#/c/438887/3 | |
| 13:57:17 | mriedem | artom: that's what i'm asking | |
