#openstack-nova - 2017-01-18
19:21:21 jaypipes mriedem: done.
19:37:14 mriedem jroll: can you have the same vif id in a list of ports and a list of portgroups?
19:37:16 mriedem for the same node?
19:53:27 mriedem vdrok: i've got some questions in https://review.openstack.org/#/c/388756/
19:53:32 jroll mriedem: no, a vif id can only be attached to one thing, AIUI
19:54:21 mriedem jroll: question the 2nd: can you have a port in more than one portgroup for the same node?
19:55:29 jroll mriedem: no
19:55:53 mriedem 3rd: who is your daddy and what does he do?
19:58:39 jroll :P
19:59:18 vdrok mriedem: thanks, a bit late now, will post replies tomorrow. Short version - duplicates are not possible because of the way nova generates id ( was asked by rloo in previous PS ) and cloud init does not validate parameters :)
19:59:46 mriedem ok
20:13:04 wasmum instance build from an image - running fine. needed a reboot. The original image is no longer in the image store and thus instance erroring out. Any way to resolve that?
20:13:38 mriedem wasmum: did you snapshot the instance?
20:13:49 mriedem do you have the image in the image cache on the compute host?
20:14:17 wasmum mriedem: image cache, tell me more?
20:16:20 mriedem if you're using the libvirt driver, it will store the base image on the compute host the first time it uses it so it doesn't have to re-download commonly used images that build on the same host
20:16:47 mriedem i believe the image cache will clean after itself after there are no instances using a given image in the cache on that host though after some period of time
20:17:16 wasmum where does it pull that image down too?
20:17:26 wasmum file location? I'll check ?
20:17:37 mriedem should be under the instance state path, so i think /var/lib/instances somewhere
20:17:46 openstackgerrit Sergey Nikitin proposed openstack/nova: Change parent of diagnostics objects to NovaObject class https://review.openstack.org/394480
20:17:46 openstackgerrit Sergey Nikitin proposed openstack/nova: Standardization of VM diagnostics info API. https://review.openstack.org/355540
20:17:47 openstackgerrit Sergey Nikitin proposed openstack/nova: Completed implementation of instance diagnostics for Xen https://review.openstack.org/399613
20:18:14 mriedem see the image_cache_manager_interval config option
20:18:25 mriedem and image_cache_subdirectory_name
20:18:53 mriedem and cache_images
20:19:54 mriedem are you using local disk or shared?
20:20:07 cfriesen__ does the separation of some models out into api_models.py have any implications for upgrades? or are they still the same DB tables, just moving the python code around?
20:20:15 mriedem mdbooth: any idea if we have any decent documentation anywhere about the image cache manager?
20:20:32 mriedem cfriesen__: such as?
20:20:33 mriedem flavors?
20:20:54 mriedem cfriesen__: api_models is the API DB schema
20:21:07 mriedem some tables are the same or similar, like flavors / instance_types
20:21:27 mriedem cfriesen__: the models are not entirely the same though, i.e. the API DB doesn't use the soft delete mixin (the deleted and deleted_at columns are not in the API DB)
20:21:48 mriedem cfriesen__: the nova-manage db online_data_migrations is meant to move the data from the cell db to the api db
20:21:52 mriedem s/cell/nova/
20:22:22 openstackgerrit Sergey Nikitin proposed openstack/nova: DO NOT MERGE https://review.openstack.org/422221
20:22:24 cfriesen__ mriedem: I was looking at InstanceGroup in particular
20:23:53 cfriesen__ mriedem: a cursory check didn't see any code to migrate InstanceGroup data from the old model to the new
20:26:54 mriedem cfriesen: https://github.com/openstack/nova/blob/master/nova/objects/instance_group.py#L525
20:27:25 mriedem cfriesen: called from here https://github.com/openstack/nova/blob/master/nova/cmd/manage.py#L612
20:27:47 mriedem which is initially called from, let's all say it now, https://github.com/openstack/nova/blob/master/nova/cmd/manage.py#L763
20:29:32 cfriesen mriedem: much appreciated
20:29:41 mriedem yw
20:36:14 wasmum mriedem: looks like it was built from a snapshot, snapshot was deleted
20:36:38 wasmum learning lessons on why not to build snowflakes
20:36:56 mriedem wasmum: and the image isn't cached on the compute host?
20:37:35 wasmum looks like it was. tried to "start" the instance using virsh and got the error of the missing backup file
20:38:04 wasmum looks like it was in the instances path in a "_base" directory and that must have expired?
20:38:33 mriedem not sure
20:38:40 mriedem there is a related write up from kashyap here https://kashyapc.com/2013/03/03/openstack-nova-dealing-with-unused-base-images/
20:45:44 openstackgerrit Sergey Nikitin proposed openstack/nova: Standardization of VM diagnostics info API. https://review.openstack.org/355540
20:45:44 openstackgerrit Sergey Nikitin proposed openstack/nova: Completed implementation of instance diagnostics for Xen https://review.openstack.org/399613
20:46:05 wasmum mriedem: thanks a ton
20:46:18 mriedem yw
20:48:38 openstackgerrit Sujitha proposed openstack/nova: Adding auto_disk_config field to InstancePayload https://review.openstack.org/419185
20:52:12 mriedem edleafe: i know you're on PTO but are you satisfied https://review.openstack.org/#/c/418134/6/nova/tests/functional/db/test_compute_node.py@102 ?
20:53:03 mriedem i guess you're looking for a slight wrinkle there
20:53:05 edleafe mriedem: I was only on PTO Monday :)
20:53:09 mriedem we have 2 computes, you want 1
20:53:12 mriedem make sure you get 1 and not 2
20:53:36 edleafe mriedem: I wanted a case where only one node was returned. The current are either all or none
20:53:40 mriedem yeah
20:53:40 mriedem ok
20:54:01 mriedem i'll add that quick
20:55:22 edleafe mriedem: I was going to add it myself, but I didn't want to mess up bauzas's stuff
20:55:44 mriedem i've got it
20:59:40 openstackgerrit Matt Riedemann proposed openstack/nova: Add ComputeNodeList.get_all_by_uuids method https://review.openstack.org/418134
20:59:41 openstackgerrit Matt Riedemann proposed openstack/nova: WIP: Scheduler calling the Placement API https://review.openstack.org/417961
21:00:12 mriedem +2 on that mofo now
21:00:50 edleafe mriedem: kewl
21:01:09 mriedem i'm trying to work on my list of 'these bp patches need another +2' by the end of hte day
21:04:46 oomichi alex_xu: yeah, the first one is good fo me, thanks Kevin_Zheng and alex_xu
21:05:35 oomichi alex_xu: https://review.openstack.org/#/c/415330/ has johnthetubaguy's -1
21:06:25 openstackgerrit Ruby Loo proposed openstack/nova: Generate necessary network metadata for ironic port groups https://review.openstack.org/388756
21:13:32 mriedem mikal: so you love the metadata api,
21:14:18 mriedem mikal: would changing the content of the network_data.json dict within the metadata api response constitute a bump in the API version, even though we don't filter the results to that level of granularity? i.e. https://review.openstack.org/#/c/388756/18/nova/virt/ironic/driver.py
21:14:27 mriedem well,
21:14:53 mriedem this would actually only be config drive since this is modified when the instance is created for the config drive and wouldn't be available via the metadata API, so nvm
21:21:01 openstackgerrit Francesco Santoro proposed openstack/nova: os-vif: convert libvirt driver to use os-vif for fast path vhostuser https://review.openstack.org/385061
21:49:55 openstackgerrit Pushkar Umaranikar proposed openstack/nova: [Do not merge] Remove unused columns from BuildRequest table in nova_api db https://review.openstack.org/422259
21:58:16 openstackgerrit Eric Fried proposed openstack/nova: Introduce base PowerVM driver (disk drv) https://review.openstack.org/409401
22:00:45 openstackgerrit Claudiu Belu proposed openstack/nova: hyper-v: Adds support for VMs with nested virtualization https://review.openstack.org/398509
22:32:28 mriedem claudiub: should https://review.openstack.org/#/c/397722/ be abandoned?
22:34:02 EmilienM mriedem: quick update on placement thing I reported this morning. We found a problem in HAproxy config in TripleO, we're working on it now. It's probably related. It's green for Puppet OpenStack CI.
22:34:10 mriedem ok
22:34:16 EmilienM bauzas ^ for your morning
23:06:20 openstackgerrit Zhenyu Zheng proposed openstack/nova: Strict pattern match query parameters https://review.openstack.org/420494
23:07:23 mriedem anthonyper: you might be able to triage this https://bugs.launchpad.net/nova/+bug/1655662
23:07:23 openstack Launchpad bug 1655662 in OpenStack Compute (nova) "libvirt xen hvm guests can't hot plug (attach detach) default block devices" [Undecided,New]
23:16:45 mriedem melwitt: https://review.openstack.org/#/c/420451/ and down need your watchful eye
23:17:59 melwitt ack
23:26:49 melwitt mriedem: I had been thinking, what about deleting erroneously created cells that have e.g. broken urls in them? I guess the thinking is, those won't have hosts or instances mapped to them since their urls never worked?
23:27:36 mriedem deleting them how?
23:27:41 mriedem like, automatically?
23:27:59 melwitt I'm just imagining someone having a problem because they made a mistake creating some cell with a wrong url in it and they can't get rid of it from their list_cells view
23:28:01 melwitt no
23:28:32 melwitt oh, wait, I guess those would be empty
23:28:37 mriedem yeah :)
23:28:41 mriedem so, just use delete_cell ?
