#openstack-nova - 2017-06-09
14:42:34 artom I'm pretty sure mriedem reads the code as bedtime stories :)
14:50:39 kashyap artom: melwitt: Another way to look at the transient / persistent is:
14:50:43 kashyap If you are going to manage the guest yourself (e.g. via `virt-manager`), you want persistent domains by default, so that even when the guest powers down, libvirt still remembers all the details, and can use those details to reboot the guest.
14:50:58 kashyap However, if you are using a higher-level application to manage guests (like Nova), you probably prefer transient guests, since all the smarts for managing the guests are tied to the cluster as managed by Nova, while libvirt management of persistent guests is local only to one host.
14:51:07 kashyap And lastly...
14:51:40 kashyap A change to a persistent guest is only made on the host where the guest is currently living -- but in a cluster setup, you want to make sure the change lives on, no matter which host in the cluster is currently running the guest; which is why Nova takes care of the configuration, and uses transient guests instead of letting libvirt store (potentially stale) information.
14:51:47 kashyap </EOM>
14:52:36 artom kashyap, aha!
14:52:43 artom That's very helpful, thanks!
14:53:26 kashyap Np; /me wonders if I should paste the above in a .txt file and put it on the web somewhere. I'm sure it's not the first time this came up
14:53:57 artom kashyap, the libvirt docs are pretty sparse on the "why"
14:54:03 kashyap Yeah, I hear you
14:54:14 artom They explain "what", but without the context you just gave, that's not very useful
14:55:13 kashyap I agree, it can be improved
14:55:42 kashyap artom: In other 'news', for upstream QEMU, I began writing a long document for its block operations. An HTML version - https://kashyapc.fedorapeople.org/virt/qemu/live-block-operations.html
14:56:08 kashyap It took a couple of months to slowly chip away at it
14:56:15 kashyap Still in review on upstream qemu-devel list

14:59:01 artom bauwser, your message to close the bug looks fine to me.
14:59:26 artom But perhaps you're right, we need to be clearer in the documentation that we don't make guarantees about nic ordering
15:02:02 bauwser artom: I can amend api-ref
15:02:14 bauwser well, if gerrit allows me...
15:04:23 openstack Launchpad bug 1696759 in OpenStack Compute (nova) "Inconsistent RabbitMQ messages after subnet update" [Undecided,New]
15:04:23 bauwser gibi: would love your insights on https://bugs.launchpad.net/nova/+bug/1696759
15:05:59 bauwser gibi: and also, I was looking at a Launchpad tag for that one, can't find it, so will use 'notifications'

15:22:58 bauwser artom: see https://review.openstack.org/472733
15:23:03 danpawlik Hi. Why when I have different password for placement user as nova api has, nova-status upgrade check is raising an error? Is this normal?
15:25:38 artom bauwser, thanks for proposing that, left a suggestion :)
15:26:20 artom bauwser, if you want I can just write the thing myself
15:30:41 stvnoyes mriedem, johnthetubaguy, I finally got migrate working with the cinder v3. The review is here - https://review.openstack.org/#/c/463987/ , please take a look when you get a chance. thx.
15:30:55 bauwser artom: absolutely, flood is yours
15:31:29 bauwser artom: you're Canadian, at least living there, so your english skills are way better than mines
15:31:54 bauwser even if you're living in a very specific area where people speak way more French than we do
15:32:13 bauwser and related, I'll go on 'fin de semaine' soon
15:33:15 artom bauwser, bonne fin de semaine alors :)
15:33:46 bauwser ooooh, and *floor*, not flood
15:34:13 artom bauwser, I know, but we did get flooding in the periphery of Montreal not long ago, so you were kinda correct
15:34:32 artom If you'd said that to vladikr you'd have been 100% right ;)
15:34:37 bauwser orly?
15:34:38 artom Happily, his house was spared
15:34:53 bauwser oh yeah, I think I heard that
15:35:04 vladikr :)

16:16:05 breton hi
16:17:22 ajay i am seeing a failure in nova-compute creating resources providers for placement on ocata
16:17:24 breton what happens if notification https://github.com/openstack/nova/blob/5d95cb9dbca403790db4e9680919e6716fa5cb76/nova/compute/manager.py#L2092-L2094 fails due to rabbit failure for example? Will the instance status be set to "Failed"?
16:17:31 ajay Failed to create resource provider record in placement API for UUID eff80c6e-a087-458e-8821-8ae4a9f64387. Got 300: {"choices": [{"status": "SUPPORTED", "media-types": [{"base": "application/json", "type": "application/vnd.openstack.compute+json;version=2"}], "id": "v2.0", "links": [{"href": "http://15.0.0.42:8778/v2/resource_providers", "rel": "self"}]}, {"status": "CURRENT", "media-types": [{"base": "application/json", "type":
16:17:50 ajay it seems like it is posting to version=2 even though all my nova endpoints are 2.1
16:19:24 ajay anyone have an idea why this api incompatibility with placement
16:24:40 cfriesen is there a novaclient command that does a GET on /servers/list ?
16:27:23 cfriesen whoops, I mean a GET on /servers
16:30:23 cfriesen answered my own question..." nova list --minimal" will do it.
16:39:45 superdan ajay: placement is a different api versioning scheme
16:40:06 superdan ajay: if placement is running, I would suspect a problem with your service catalog
16:40:17 superdan ajay: do you see any logs from placement that indicate the computes are even hitting it?
16:43:19 openstackgerrit Ildiko Vancsa proposed openstack/nova master: Remove check_detach https://review.openstack.org/446671
16:54:14 ajay no i dont see any logs on placement
16:54:19 ajay saying compute is hitting it
16:56:10 superdan ajay: I expect that means you've got your service catalog pointing to the wrong thing

19:09:23 tasker is there a way to modify the 'instance_system_metadata' of an active instance?
19:09:40 tasker other than modifying the database.
19:12:23 tasker the instance was create with "hw_qemu_guest_agent=yes" set on the image. this value was pulled into the instances system metadata (as "image_hw_qemu_guest_agent"). however, my environment's libvirt is not working properly and subsequently neither are nova snapshots ('image-create'). I need to disable this key without rebuilding the instance.

00:13:31 Ajay any idea why one would get a 300 status code response from placement while nova compute creates a resource provider
