#openstack-nova - 2017-12-21
14:49:09 mriedem since that's the cost of having a not interoperable cloud
14:51:00 alex_xu mriedem: yea, that's true
14:52:09 kholkina hi all! is it possible to update user_data on a running instance?
14:52:36 kholkina I've found a blueprint but it looks like abandoned https://blueprints.launchpad.net/nova/+spec/update-userdata
14:52:56 mriedem kholkina: no. there is a new microversion in queens that allows you to rebuild an instance and change the userdata at that time,
14:53:02 mriedem but rebuild != running
14:54:16 kholkina maybe it's planned to work on that blueprint?
14:54:34 mriedem i hadn't heard of it before today, so i don't know of any plans to work on that
14:54:58 mriedem lyarwood: you want to tickle the ocata and newton versions of this too? https://review.openstack.org/#/q/I214a44f0eee7d90be5cd89f32f6e0017b19a3fd6
14:55:09 openstackgerrit Takashi NATSUME proposed openstack/nova master: api-ref: Example verification for servers.inc https://review.openstack.org/529520
14:56:35 lyarwood mriedem: planning to once it lands in stable/pike
14:57:32 kholkina so now the only way to do this is via updating database?
14:59:12 mriedem kholkina: on a running instance? yes that's what you'd have today
14:59:28 mriedem kholkina: if you're interested in supporting this via the API, you'd have to take over ownership of https://blueprints.launchpad.net/nova/+spec/update-userdata
14:59:33 mriedem and propose a spec for the rocky release
14:59:37 mriedem to the nova-specs repo
14:59:39 mriedem since it's an API change
15:00:26 kholkina ok, thanks

15:59:45 mdbooth lyarwood: ^^^ Fixed
16:00:24 mdbooth lyarwood: Lets wait for Zuul, though.
16:02:43 kholkina mriedem: is there a better method to manage ssh-keys on instances?
16:03:19 mriedem better method compared to what?
16:03:24 mriedem keypairs?
16:04:06 kholkina I planned to manage keys via user_data
16:04:38 mriedem i've heard of some deployments that don't use keypairs? but penick isn't around
16:04:44 mriedem rybridges: ^?
16:05:03 mriedem they use config management to inject information into the guest once the guest registers with their service
16:22:08 openstackgerrit Matt Riedemann proposed openstack/nova stable/ocata: Fix an error in _get_host_states when deleting a compute node https://review.openstack.org/529635
16:24:44 mnaser mriedem: mdbooth awesome thank you so much for that KeyError fix
16:28:58 mriedem thanks for reporting it
17:08:30 openstackgerrit Merged openstack/nova master: Fix duplicate allocation candidates https://review.openstack.org/528591
17:08:33 mnaser i'm trying to understand something - nova seems to allow booting an instance type that has no ephemeral storage
17:08:42 mnaser what would the size of that image be (or how is that determined?)
17:09:00 mnaser i noticed when using heat, it doesnt let you do this (except the nova api actually lets you)
17:10:28 mriedem mdbooth: ^
17:11:21 mriedem mnaser: what is the flavor.disk value?
17:11:33 mriedem "The size of the root disk that will be created in GiB. If 0 the root disk will be set to exactly the size of the image used to deploy the instance. However, in this case filter scheduler cannot select the compute host based on the virtual image size. Therefore, 0 should only be used for volume booted instances or for testing purposes."
17:11:52 mnaser mriedem: where was that? disk=0

17:13:32 kashyap mdbooth: Also if you respin, in the commit s/was is/is/; s/gust/guest/
17:13:51 kashyap (In that unused argument thing.)

18:07:05 kashyap A no-brainer, already has +2: https://review.openstack.org/#/c/527691/ ("conf: libvirt: Cleanup CPU modelling related options")
18:08:56 openstackgerrit Merged openstack/nova master: XenAPI: create vGPU for instance https://review.openstack.org/516899
18:21:59 mriedem kashyap: no-brainer huh
18:22:02 mriedem question inline

18:27:32 mriedem jaypipes: can i interest you in some pure uncut alternate hosts https://review.openstack.org/#/c/511358 ?
18:28:14 jaypipes mriedem: sure thing.
18:28:53 jaypipes mriedem: currently have electrician's at my house running new conduit and installing a new dishwasher that went out earlier today. fun! on the day we're doing xmas dinner in the evening. awesome timing, as always.
18:29:55 mriedem make a centerpiece of leftover conduit to lighten the mood
18:30:20 mriedem or something else that's crafty from "at home with amy sedaris"
18:39:34 jaypipes mriedem: :)
18:40:18 mriedem btw, i recommend that you recommend that show to julie
18:41:31 jaypipes mriedem: I'm pretty sure she would already know about it. she loves anything sedaris. amy or david.
18:42:45 openstackgerrit Matt Riedemann proposed openstack/nova master: Add retry_on_deadlock decorator to action_event_start https://review.openstack.org/529672
18:42:47 mriedem then we are kindred spirits
18:52:09 openstackgerrit Matt Riedemann proposed openstack/nova master: libvirt: don't log snapshot success unless it actually happens https://review.openstack.org/529674
19:02:07 jaypipes mriedem: questions for you in that alternate hosts patch
19:09:39 oomichi mriedem: nice guide by https://review.openstack.org/#/c/529618/ just some comments
19:09:46 edleafe jaypipes: answering...
19:10:17 mriedem edleafe: on it already
19:10:20 mriedem but we can compare notes
19:10:30 oomichi mriedem: btw is it difficult to get bp approval of https://blueprints.launchpad.net/nova/+spec/vmware-boot-uefi ? the corresponding code seems ready
19:11:53 edleafe jaypipes: answered. I didn't have a good answer to https://review.openstack.org/#/c/511358/47/nova/compute/manager.py
19:12:01 edleafe maybe mriedem will
19:12:35 mriedem jaypipes: replied
19:13:03 mriedem oomichi: no one ever brought that up for queens,
19:13:13 mriedem in the 2-3 months they could have brought it up
19:13:46 oomichi mriedem: ok, let's skip it
19:14:17 mriedem given how trivial this is we could possibly make an exception
19:14:36 mriedem i just don't generally like to make exceptions because then you do it for one blueprint and everyone else expects it
19:16:57 melwitt there's a pretty simple libvirt driver refactor needing a +W that's en route to native luks encryption if anyone can review https://review.openstack.org/#/c/460243
19:17:01 jaypipes mriedem: k, both bottom patches +Wd
19:17:07 mriedem oomichi: replied
19:17:09 mriedem jaypipes: danka
19:17:16 jaypipes mriedem: bitte
19:18:57 edleafe jaypipes: thx. Guess we'll wait til Jan for the final patch
