| 10:57:30 | hrw | tetsuro: kvm is in-kernel hypervisor with qemu used as interface to it. sth like that iirc | |
| 10:58:06 | mdbooth | lyarwood: Doesn't look that bad | |
| 10:58:11 | mdbooth | Not in driver.py, anyway | |
| 11:06:59 | cdent | you're probalby right | |
| 11:08:15 | sean-k-mooney | cdent: well when it comes to micro version is not really someting i spend much time thinking about normally so im not sure about that but im leaning towords the bump in this instance | |
| 11:08:42 | cdent | you've provided the critical point: a client may make decision based on the value | |
| 11:30:37 | openstackgerrit | Merged openstack/nova master: Updated from global requirements https://review.openstack.org/531737 | |
| 11:34:36 | kashyap | tetsuro: KVM runs part of the guest instructions directly on the baremetal CPU (taking advantage of CPU Virtualization extensions - Intel-VMX / AMD-SVM). While QEMU provides rest of the PC-like components (n/w card, disk interface, etc) | |
| 11:36:55 | openstackgerrit | Jie Li proposed openstack/nova master: Support volume-backed server rescue https://review.openstack.org/531524 | |
| 11:37:11 | tetsuro | hrw, kashyap: good to know. thanks for the information. | |
| 11:38:09 | tetsuro | sean-k-mooney, cdent: thank you for reviewing, let me wait for matt to leave comments here. | |
| 11:39:03 | sandanar | hi.. does anyone know what is the reason behind CONF.libvirt.volume_use_path always returns the default value and not the one passed in [libvirt] section of /etc/nova/nova.conf - https://bugs.launchpad.net/nova/+bug/1723928 this is causing multipath failures on the cinder side | |
| 11:39:04 | openstack | Launchpad bug 1723928 in os-brick "In case of volume_use_multipath=True, Nova unable to fetch CONF.libvirt.volume_use_multipath value from nova.conf" [Undecided,New] | |

| 11:41:17 | lyarwood | kashyap: http://paste.openstack.org/show/641098/ - just noticed this on stable/pike https://review.openstack.org/#/c/531407/ | |
| 11:41:38 | lyarwood | kashyap: load of migration failed: Operation not permitted | |
| 11:42:40 | kashyap | lyarwood: That rings a bell, I recall seeing a bug for the VQ size | |
| 11:48:00 | kwathore | @meriedm: This is very critical bug which we have observerd releated to multipath: https://bugs.launchpad.net/nova/+bug/1723928 | |

| 11:55:34 | openstackgerrit | Rodolfo Alonso Hernandez proposed openstack/os-vif master: Add support for Windows network commands https://review.openstack.org/487405 | |
| 11:56:29 | kashyap | lyarwood: From the top off my head, I vaguely recall a couple of fixes from Virtio net devices from StefanH. The bug links are eluding me | |
| 11:56:48 | kashyap | I asked Stefan for the specific versions that fix these screwey virtio queue issues | |
| 11:57:01 | kashyap | Will let ya know once I hear back from him | |
| 11:57:04 | lyarwood | kashyap: cool thanks | |

| 12:28:56 | ildikov | johnthetubaguy: gibi: hi :) this tiny patch needs a second +2 if either of you have a few minutes: https://review.openstack.org/#/c/529695/ | |
| 12:29:10 | ildikov | johnthetubaguy: gibi: thanks in advance :) | |
| 12:38:59 | openstackgerrit | Lajos Katona proposed openstack/nova master: Deduplicate aggregate notification samples https://review.openstack.org/531162 | |
| 12:39:36 | gibi | ildikov: done :) | |
| 12:44:32 | openstackgerrit | Lajos Katona proposed openstack/nova master: Deduplicate service status notification samples https://review.openstack.org/531381 | |
| 12:44:48 | ildikov | gibi: thanks!! :) | |
| 13:06:33 | sean-k-mooney | stephenfin: just looking at https://review.openstack.org/#/c/531358 looks like when you change your email to stephenfin instead of sfinucan you didnt update your global git user name. not sure if thats intentional but just taught i would point it out | |
| 13:06:50 | sean-k-mooney | * global git email | |

| 13:26:57 | mdbooth | Can anybody remind me about our stable backport window re https://review.openstack.org/#/c/530744/ | |
| 13:27:07 | mdbooth | That's an Ocata backport. Is it going to land? | |
| 13:27:16 | mdbooth | s/going/eligible/ | |
| 13:27:28 | mdbooth | stephenfin: ^^^ is your backport of my patch, btw | |
| 13:28:23 | lyarwood | mdbooth: looking | |
| 13:28:36 | efried | claudiub Wow, congratulations! That's been a long time coming. | |
| 13:28:57 | sean-k-mooney | mdbooth: i think ocata is still supported for backports assuimg the patch would normally qualify. | |
| 13:29:28 | sean-k-mooney | mdbooth: the defult stable supprot is 12 months with the option to extend to 18 i think | |
| 13:29:42 | stephenfin | sean-k-mooney: I've got both registered but need to configure 'user.email' on most repos | |
| 13:29:45 | lyarwood | mdbooth / sean-k-mooney ; by the book it would need to be a >=high impact bug | |
| 13:29:58 | stephenfin | sean-k-mooney: stephenfin is only an alias anyway so either one works | |
| 13:29:59 | lyarwood | mdbooth: and I think this is valid still for ocata tbh | |
| 13:30:30 | mdbooth | lyarwood: Yeah, bug doesn't have that metadata, but I'd say it should qualify | |
| 13:30:42 | sean-k-mooney | stephenfin: ya i remember you telling me that just was not sure if you missed it or not | |
| 13:30:58 | lyarwood | mdbooth: yeah, had to read through the commit but yup IMHO it's fine, I'll review the pike version now | |
| 13:31:17 | mdbooth | lyarwood: Thanks | |
| 13:33:00 | sean-k-mooney | stephenfin: lyarwood: since we are talking about backport i would like to backport this to pike and ocata too its trival enough but its a latent bug that has been present since os-vif was first created | |
| 13:33:02 | claudiub | efried: yeay, gonna have to celebrate. :)) | |
| 13:33:25 | claudiub | the patches on nova still need reviews though. :D | |
| 13:33:41 | sean-k-mooney | stephenfin: lyarwood by the book would this qualify for backporting? | |
| 13:33:43 | stephenfin | sean-k-mooney: "this" being? | |
| 13:33:53 | sean-k-mooney | stephenfin: https://review.openstack.org/#/c/531465/ | |
| 13:39:05 | lyarwood | sean-k-mooney: yeah I'd say that would be valid for ocata, it's trivial but useful. I'm not sure if there are other considerations that need to be taken into account for libs however. | |
| 13:41:21 | sean-k-mooney | lyarwood: in normal execution i think the edgecase that causes the interface not to be present happens very infrequently however in the gate it was causing random failures hence why it has been latent for so long | |
| 13:45:34 | openstackgerrit | Zhenyu Zheng proposed openstack/nova master: Use neutron port_list when filtering instance by ip https://review.openstack.org/525505 | |
| 13:53:49 | kashyap | lyarwood: So apparently there are different reasons for hitting that error you pointed out earlier. (The bug URL I was looking for was, which has a slightly different error): https://bugzilla.redhat.com/show_bug.cgi?id=1378788 (Race condition during virtio-blk dataplane stop triggers "Virtqueue size exceeded") | |
| 13:53:50 | openstack | bugzilla.redhat.com bug 1378788 in qemu-kvm-rhev "Race condition during virtio-blk dataplane stop triggers "Virtqueue size exceeded"" [High,Closed: errata] - Assigned to stefanha | |
| 13:55:14 | mriedem | dtantsur: the devstack dependency for https://review.openstack.org/#/c/527289/ is now merged | |
| 13:55:50 | dtantsur | mriedem: thanks, approved | |
| 13:55:54 | mriedem | thanks | |
| 13:56:28 | lyarwood | kashyap: cool thanks, /me reads | |
| 13:56:56 | kashyap | lyarwood: But we still don't have a root cause for the unique error you pointed out | |
| 13:57:03 | kashyap | The above bug was fixed in version QEMU 2.6 & above, though. | |
| 13:57:34 | lyarwood | kashyap: kk, this is with 2.8 FWIW | |
| 13:57:58 | lyarwood | kashyap: do we need a bug open somewhere for this in that case? | |
| 13:57:59 | kashyap | lyarwood: Hmm, okay, Stefan just responded: | |
| 13:58:15 | kashyap | "This issue probably requires debugging. This kind of problem can occur if the vring memory is not up-to-date (e.g. requests were processed after migration paused the guest)." | |
| 13:58:36 | kashyap | lyarwood: Do you see multiple hits for this? | |
| 13:58:49 | kashyap | lyarwood: Yeah, an open bug helps definitely, | |
| 13:59:00 | kashyap | ...as others hitting it may have more reliable reproducers. | |
| 13:59:10 | lyarwood | kashyap: I've not looked, I'll check now, if we do then I'll create a LP for it | |
| 14:07:08 | edmondsw | mriedem and sdague, the powervm OVS patch is fully ready for reviews now, passing CI | |
| 14:07:11 | edmondsw | https://review.openstack.org/#/c/422512/ | |
| 14:07:32 | edmondsw | we're working a CI issue for the SEA patch this morning, but as stated yesterday the code is ready for review | |
| 14:07:50 | edmondsw | will update on the CI for SEA when we have that fixed | |
| 14:09:03 | mriedem | i would expect efried to review that first | |
| 14:09:25 | efried | will do | |
| 14:10:09 | lyarwood | kashyap: nvm we already have a LP from mriedem for this here - https://bugs.launchpad.net/nova/+bug/1737625 | |
| 14:10:10 | openstack | Launchpad bug 1737625 in OpenStack Compute (nova) "live migration failed with "Failed to load virtio-blk:virtio" (libvirt/qemu)" [Undecided,Confirmed] | |
| 14:11:56 | kashyap | lyarwood: Ah, thanks. | |
| 14:19:11 | efried | mriedem Done | |
| 14:19:32 | efried | (OVS, that is) | |
| 14:28:11 | stephenfin | mriedem: Our Python 3 woes have been resolved https://review.openstack.org/#/c/530950/ | |
| 14:28:32 | stephenfin | mriedem: Fancy revisiting https://review.openstack.org/#/c/345399/ at some point this week? | |
| 14:40:02 | ildikov | mriedem: are you planning to do further tweaks on the multi-attach chain in Nova? | |
| 14:42:42 | mriedem | stephenfin: maybe | |
| 14:42:45 | mriedem | ildikov: maybe | |
