03:32:38 openstack Launchpad bug 1670262 in OpenStack Compute (nova) "DBNonExistenceDatabase: Unknown database "nova_cell0"" [Undecided,Incomplete]
03:32:38 diga mriedem: https://bugs.launchpad.net/nova/+bug/1670262 Getting this issues when setup fresh devstack & run server list command from cli
03:32:57 mriedem diga: then create nova_cell0
03:34:46 mriedem diga: https://github.com/openstack-dev/devstack/blob/8fe48af1625cd2deca496de81dd72573e78b3ef2/lib/nova#L709
03:35:11 diga mriedem: okay, will go through it
03:35:41 diga mriedem: may be my devstack source code is old
03:35:49 mriedem dansmith: i'm actually not sure why he couldn't have just modified https://review.openstack.org/#/c/441543/2/nova/tests/functional/api/openstack/placement/test_report_client.py to call set_inventory_for_provider with a garbage resource class
03:35:50 diga mriedem: need to pull latest
03:35:54 diga mriedem: thank you
03:35:59 mriedem and assert it raises the expected exception
03:36:03 mriedem i can try that quick
03:45:11 mriedem dansmith: yeah this would have been much easier https://gist.github.com/mriedem/1fb38bd4bb62cff0c5bcd90abb049c88
03:48:48 dansmith oh well
03:49:40 openstackgerrit Matt Riedemann proposed openstack/nova master: Add functional test for bad res class in set_inventory_for_provider https://review.openstack.org/442254
03:49:42 mriedem dansmith: ^ oh nothing
03:50:03 dansmith that's what we need, more patches
03:50:16 mriedem "more good patches"
03:50:21 mriedem was the BCN phrase of the week
03:51:31 dansmith heh
03:54:36 openstackgerrit Matt Riedemann proposed openstack/nova master: autospec the virt driver mock in test_resource_tracker https://review.openstack.org/442258

06:42:16 jvarlamova__ Hi everyone! Can someone help me? I get error "Failed to allocate the network(s), not rescheduling", when trying to boot multiple instances in parallel. What could be the reason?

07:58:02 bauzas good morning Nova
08:03:49 slaweq hello
08:03:59 slaweq I have a question about rebuild of instance
08:05:24 slaweq (I'm using Juno release still), so sometimes when I rebuild active instance it's rebuild fine but in libvirt logs I can see something like "Cannot open log file: '/var/log/libvirt/qemu/instance-002d6c52.log'" and instance is then shutdown by libvirt
08:05:49 slaweq maybe someone of You got such issue already and know how to fix it?

10:08:30 mdbooth lyarwood: What do you know of lvm thin pools?
10:13:12 openstackgerrit Akira KAMIO proposed openstack/nova master: Replace root volume during rebuild https://review.openstack.org/442295
10:14:17 lyarwood mdbooth: not much, I've never really had the chance to use them tbh
10:14:31 mdbooth lyarwood: k
10:14:59 lyarwood mdbooth: we don't use them in the lvm imagebackend do we?
10:15:20 mdbooth lyarwood: I'm just reviewing this patch: https://review.openstack.org/#/c/442126/2/nova/virt/libvirt/storage/lvm.py
10:15:44 mdbooth I'm curious, because I thought we already did use them if we specified sparse
10:15:55 mdbooth And this patch is adding something new
10:16:14 mdbooth I'm just reading some man pages to try to work out what's different from what we already do
10:19:21 markus_z lyarwood: Anything I can do for the stable/newton backport https://review.openstack.org/#/c/406898/ ? I answered all questions to that so far.
10:20:25 sfinucan johnthetubaguy: Could you take a look at https://review.openstack.org/#/c/435575? It's pretty noddy but it keeps getting into merge conflicts
10:20:39 openstackgerrit Rodolfo Alonso Hernandez proposed openstack/nova-specs master: Enable SR-IOV NIC offload feature discovery https://review.openstack.org/435954
10:20:40 lyarwood markus_z: I was going to take another look at it today before matt gets online so we can hopefully close it out
10:20:54 lyarwood markus_z: I think you've answered his questions but just wanted to check first
10:21:03 johnthetubaguy sfinucan: oh, I can see what why would happen, yeah, looking
10:21:12 sfinucan johnthetubaguy: Cheers :)
10:21:46 lyarwood mdbooth: ah right, before we would just create a sparse LV and manually grow that LV (I *think*)
10:21:55 markus_z lyarwood: OK, thanks. JFYI, I might leave early today ~1600UTC
10:22:05 lyarwood at least, that's what RHEV would do back in the day with sparse LVs
10:22:14 mdbooth johnthetubaguy: Following our discussion last week, I suspect that even with Cinder V3 we're going to end up doing this: https://review.openstack.org/#/c/383859/
10:22:39 mdbooth i.e. nova-side management of shared connections
10:24:12 mdbooth johnthetubaguy: Any chance we could get that over the line? Fixes an issue today, I suspect the code can eventually be lifted elsewhere.
10:24:38 johnthetubaguy mdbooth: given my queue of work today, I can't see me getting the time to look at that I am afraid
10:25:00 mdbooth johnthetubaguy: Well it's been sitting for months, so I'm not going to stress about today :)
10:25:29 mdbooth If you have a 'sometime soon' list, though, that would be awesome :)
10:25:39 johnthetubaguy mdbooth: I understand it better now, having chatted through it, which is all good, yeah, its totally on that list
10:25:48 mdbooth Cool, thanks.
10:26:08 johnthetubaguy mdbooth: if I haven't been to review that early next week, totally bug me again
10:26:18 mdbooth johnthetubaguy: You may regret that.
10:26:21 mdbooth Sure.
10:26:28 johnthetubaguy mdbooth: probably, but its for the best :)
10:30:36 openstackgerrit Akira KAMIO proposed openstack/nova master: Replace root volume during rebuild https://review.openstack.org/442295
10:30:37 gibi johnthetubaguy: hi! a frindly reminder about the Show persisted scheduler hints in server details spec https://review.openstack.org/#/c/440580/ It gathered even more +1s yesterday :)

10:35:40 jvarlamova__ Hi, can someone help me? I get error "VirtualInterfaceCreateException: Virtual Interface creation failed", when trying to boot multiple instances in parallel. What's the reason?
10:39:31 rpodolyaka jvarlamova__: could you please provide a complete stack trace from the nova-compute log?
10:40:35 openstackgerrit Stephen Finucane proposed openstack/nova master: trivial: Standardize naming of variables https://review.openstack.org/430272

11:12:56 jvarlamova__ rpodolyaka: http://pastebin.com/0jY6Ax1C
11:20:13 rpodolyaka jvarlamova__: this exception is raised when nova-compute times out waiting for vif-plugged event - https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L5052-L5061
11:21:18 rpodolyaka jvarlamova__: you should check nova-api / neutron-server / neutron l2 agent logs for this device id (== instance uuid) to see if such event was delivered to nova at all
11:27:41 mdbooth alex_xu: Hey, just thinking about your response on https://review.openstack.org/#/c/441829/4 about the cache.clear(). This is all running with the placement service, right? Are we guaranteed to only have 1 of those globally?
11:27:52 mdbooth cdent: ^^^ ?
11:28:27 mdbooth alex_xu: I'm just thinking that if a Trait is created through 1 service, then accessed through another, the cache on the second won't have been refreshed.
11:28:47 mdbooth However, I don't know how this is intended to be deployed, so this may not make sense.
11:29:31 cdent mdbooth: there's only one placement database, but could be multiple placement api servers
