| 14:40:17 | bauzas | jaypipes: no worries man | |
| 14:40:22 | bauzas | jaypipes: take rest | |
| 14:44:34 | sfinucan | jaypipes: Aye, take it easy in that case | |
| 14:45:21 | jangutter | Massive apologies again for the insane lateness of "Spec to enable Netronome SmartNIC support" https://review.openstack.org/#/c/456386/ | |
| 14:46:15 | jangutter | At least I should be online for the next couple of hours if anyone is still willing to review it. | |
| 14:50:14 | openstackgerrit | Sylvain Bauza proposed openstack/nova master: Fix AZ related API docs https://review.openstack.org/456655 | |
| 14:50:30 | bauzas | mriedem: johnthetubaguy: attempt to clarify our API docs wrt: AZs https://review.openstack.org/456655 | |
| 14:55:37 | mriedem | live migration job is spiking at 75%+ fail, i'm going to make it non-voting | |
| 14:56:28 | kashyap | mriedem: Any specific bug (or a set of bugs) that's causing it? | |
| 14:56:39 | openstack | Launchpad bug 1682453 in OpenStack Compute (nova) "Live Migration failure: operation failed: Failed to connect to remote libvirt URI - End of file while reading data: sh: 1: nc: not found: Input/output error" [High,Confirmed] | |
| 14:56:39 | mriedem | https://bugs.launchpad.net/nova/+bug/1682453 | |
| 14:56:44 | mriedem | libvirt craps it's pants | |
| 14:56:51 | mriedem | with newer libvirt/qemu | |
| 14:57:06 | mriedem | which we were told by some (cough cough) it would fix all of our problems :) | |
| 14:58:58 | kashyap | mriedem: I never make blanket promises, certainly to _you_ that it will "fix all the problems" | |
| 14:59:26 | mriedem | https://review.openstack.org/456656 | |
| 14:59:28 | kashyap | s/to/not to/ | |
| 14:59:39 | mriedem | kashyap: i'm just teasing | |
| 14:59:49 | kashyap | I know, I forgot to add a smiley | |
| 15:07:34 | owalsh | kashyap: that looks like a packaging issue, nc not installed | |
| 15:08:48 | jangutter | :O "nc not installed" conjures the same horror in me as "gcc not installed". | |
| 15:10:16 | sdague | mriedem: the fix is merged now, right? | |
| 15:10:53 | mriedem | clarks? | |
| 15:10:56 | mriedem | that merged last night | |
| 15:10:57 | mriedem | this is something else | |
| 15:11:14 | sdague | mriedem: https://review.openstack.org/#/c/456388/ | |
| 15:11:21 | sdague | no, it didn't merge until this morning | |
| 15:11:50 | sdague | also, it seems totally weird to me that libvirt would shell out to nc | |
| 15:12:56 | dansmith | sdague: it has definitely used nc for things | |
| 15:13:26 | dansmith | sdague: used to be you couldn't connect a fedora virt-manager to an ubuntu host without installing netcat, or something like that | |
| 15:13:33 | dansmith | the reverse maybe, I forget | |
| 15:19:15 | sdague | so I think this is probably the problematic commit for us - https://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=22eaee8e011645162e4b00d313bf2abdd4eb54e5 | |
| 15:19:30 | sdague | probably good to get an ubuntu packaging bug openned up on that | |
| 15:20:17 | sdague | clarkb: did you do that yet? | |
| 15:21:52 | owalsh | sdague: that's for qemu+libssh, the qemu+ssh driver always requried netcat | |
| 15:25:28 | sfinucan | owalsh: Regarding https://review.openstack.org/456571, are you saying we need user and port options even if we don't deprecate 'live_migration_uri' | |
| 15:27:10 | sdague | it looks like the libvirt-daemon recommends netcat-openbsd, but does not require it | |
| 15:27:12 | sdague | Recommends: qemu-kvm | qemu (>= 0.9.1), libxml2-utils, netcat-openbsd | |
| 15:27:38 | owalsh | sfinucan: need to use live_migration_inbound_addr to set the IP network for live migration. We can't do this with live_migration_uri AFAIK | |
| 15:29:51 | owalsh | sfinucan: I assume that's one of the main reasons for deprecating live_migration_uri | |
| 15:30:44 | owalsh | sfinucan: but to use SSH we need to pass user, maybe port too, and almost certainly extraoptions, and there is no way to set this when using live_migration_inbound_addr | |
| 15:37:19 | sfinucan | owalsh: So for 'live_migration_uri', you could conceivably set it to something like 'xen+ssh://rjones@%s/?no_verify=1'. That has both a user and extra_options | |
| 15:37:46 | sfinucan | owalsh: Do we want the same functionality for whatever's using live_migration_inbound_addr? | |
| 15:39:49 | owalsh | sfinucan: yes, currently do set the user via live_migration_uri, but we can't control which network it users. %s is always replaced with the remote hostname | |
| 15:42:00 | sfinucan | owalsh: ...and live_migration_inbound_addr provides an alternative to that, but it doesn't allow you to a username or extra_specs currently, right? | |
| 15:43:59 | sfinucan | owalsh: If we allowed you to _not_ specify '%s' for 'live_migration_uri' and instead set a static destination/IP network, would that achieve what you want? | |
| 15:44:20 | cdent | edleafe: are your resource tracker related functional tests sort of on hold? | |
| 15:44:46 | owalsh | sfinucan: you have to specify %s - it's replaced with the hostname of the live miragation target | |
| 15:45:02 | sfinucan | owalsh: That's what I'm saying. What if I removed that requirement | |
| 15:45:26 | sfinucan | Or are the two complimentary somehow? | |
| 15:46:35 | owalsh | so live_migration_uri = foo://bar@%s/ will tranlate to foo://bar@nova1/ when migrating to nova1, and foo:/bar@nova2/ when migrating to nova2 | |
| 15:48:07 | owalsh | when using the new approach when migrating to nova1 we get live_migration_inbound addr etc.. for nova1 to build the url to migrate to it | |
| 15:48:15 | owalsh | IIRC anyway | |
| 15:49:35 | owalsh | it been a while since I looked at it but I think there was consensus that the new options are required | |
| 15:49:47 | openstackgerrit | Artom Lifshitz proposed openstack/nova master: Plumbing for tagged nic attachment https://review.openstack.org/415622 | |
| 15:49:48 | openstackgerrit | Artom Lifshitz proposed openstack/nova master: Delete nic metadata when detaching interface https://review.openstack.org/435387 | |

| 15:49:55 | openstackgerrit | Artom Lifshitz proposed openstack/nova master: Plumbing for tagged volume attachment https://review.openstack.org/391941 | |
| 15:49:56 | openstackgerrit | Artom Lifshitz proposed openstack/nova master: API support for tagged device attachment https://review.openstack.org/376021 | |
| 15:49:57 | openstackgerrit | Artom Lifshitz proposed openstack/nova master: Libvirt support for tagged nic attachment https://review.openstack.org/415520 | |
| 15:57:30 | edleafe | cdent: yeah, more because I got distracted with other stuff while waiting for more feedback | |
| 15:58:18 | cdent | edleafe: yeah, just checking. I had a reminder to look at them but didn't have the current brain to say much in this round. | |
| 15:58:44 | edleafe | cdent: ok, remind me next week if you think of it | |
| 15:58:53 | cdent | ✔ | |
| 15:59:22 | mriedem | dansmith: before you change things in https://review.openstack.org/#/c/456227/ i've left some comments | |
| 15:59:29 | mriedem | looks like some were at the same time you were replying to sfinucan | |
| 15:59:30 | openstackgerrit | Dan Smith proposed openstack/nova master: Fix hypervisors api missing HostMappingNotFound handlers https://review.openstack.org/456227 | |
| 15:59:32 | dansmith | hah | |
| 15:59:33 | mriedem | doh | |
| 15:59:34 | mriedem | gdi | |
| 15:59:41 | dansmith | was literally just pushing when you said that | |
| 16:02:43 | ildikov | mriedem: johnthetubaguy: are you avaiable for the Cinder-Nova meeting? | |
| 16:02:54 | mriedem | yeah | |
| 16:18:16 | openstackgerrit | Daniel Pawlik proposed openstack/nova master: Changed network_info variable in test_create_configdrive https://review.openstack.org/436953 | |
| 16:21:11 | dtp | good morning. can we get a ruling on https://blueprints.launchpad.net/nova/+spec/conf-network-metadata-always-static-ip, please? | |
| 16:23:38 | kashyap | mriedem: That live mig job failure is due to missing `nc` (Netcat), which seems to be resolved by clarkb's -- https://review.openstack.org/#/c/456388/ ("Install netcat for libvirt live migration") | |
| 16:23:43 | kashyap | That merged about 3 hours ago | |
| 16:23:58 | mriedem | kashyap: ok, i had thought that merged last night but forgot about the devstack dependency | |
| 16:24:05 | mriedem | i'll check logstash in a bit to see if it's dropping off | |
| 16:24:33 | kashyap | mriedem: See! You seem to blame libvirt at the drop of a hat :P | |
| 16:24:52 | kashyap | You actually didn't | |
| 16:25:17 | ngupta | Hi everyone, new to this channel. I want to know where does OpenStack stand with supporting encryption for Block Storage using the RBD driver. | |
| 16:27:11 | openstackgerrit | OpenStack Proposal Bot proposed openstack/nova master: Updated from global requirements https://review.openstack.org/455960 | |
| 16:34:34 | mriedem | dansmith: is it just me, or is it weird that we don't terminate volume connections on the host when we shelve offload? | |
| 16:34:41 | mriedem | since when you unshelve, you can end up on another host | |
| 16:36:35 | dansmith | mriedem: yeah.. I assume that'd be a bug | |
| 16:36:49 | mriedem | like, the most latent bug ever... | |
| 16:37:00 | mriedem | i keep thinking i'm missing something obvious | |
| 16:37:00 | dansmith | I think there might've been some things that were left in place on the off chance it landed on the same host, but can't imagine that's right | |
| 16:37:11 | dansmith | unless we call to the old compute somehow, but we've lost that info I think | |
| 16:37:23 | dansmith | yeah, seems too obviously broken | |
| 16:37:52 | mriedem | conductor manager for unshelve calls out to scheduler to get new hosts | |
| 16:37:55 | openstackgerrit | Jianghua Wang proposed openstack/nova-specs master: Support VGPU https://review.openstack.org/450122 | |
| 16:38:03 | mriedem | plus, you could have unshelved from a host that is now down or gone | |
| 16:38:11 | mriedem | *shelved | |
| 16:38:17 | dansmith | yeah | |
| 16:41:40 | mriedem | oh btw, pike-1 milestone today | |
| 16:41:46 | mriedem | i had forgotten about the need for the tag | |
| 16:42:35 | jianghuaw_ | jaypipes, sbauza: could you help to look at this VGPU spec? | |
