| #openstack-nova - 2020-11-23 | |||
| 15:09:42 | sean-k-mooney | but i dont really see a clear smoking gun there | |
| 15:10:11 | sean-k-mooney | its adding a bunch of stuff we did not ask for but none of ti looks invalid | |
| 15:18:31 | gibi | added qemu project as affected (keep nova as you suggested) | |
| 15:20:52 | sean-k-mooney | gibi: kashyap has ping one of the qemu migration experts for input | |
| 15:21:06 | kashyap | Yeah, Dave Gilbert from upstream QEMU | |
| 15:21:17 | openstack | bugzilla.redhat.com bug 1450524 in qemu-kvm-rhev "qemu-kvm: VQ 0 size 0x100 Guest index 0x2010 inconsistent with Host index 0x2171: delta 0xfe9f" [High,Closed: worksforme] - Assigned to jasowang | |
| 15:21:17 | sean-k-mooney | there is an old https://bugzilla.redhat.com/show_bug.cgi?id=1450524 downstream bug | |
| 15:21:29 | sean-k-mooney | but it was closed as they could not reliably repoduce it | |
| 15:21:34 | kashyap | He's a fixed a similar-sounding issue as above --^ It was also triggerred by OpenStack CI | |
| 15:21:42 | kashyap | s/a fixed/fixed/ | |
| 15:22:07 | sean-k-mooney | gibi: the main delta there being virtio-ballon vs virtio-blk | |
| 15:38:42 | openstack | Launchpad bug 1737625 in OpenStack Compute (nova) "live migration failed with "Failed to load virtio-blk:virtio" (libvirt/qemu)" [Undecided,Confirmed] | |
| 15:38:42 | kashyap | sean-k-mooney: Also see this one: https://bugs.launchpad.net/nova/+bug/1737625 | |
| 15:38:58 | kashyap | Especially my comment#2, FWIW | |
| 15:45:15 | openstackgerrit | Merged openstack/nova master: Fix the instance_uuid for test https://review.opendev.org/c/openstack/nova/+/763171 | |
| 15:45:20 | openstack | bugzilla.redhat.com bug 1895702 in openstack-neutron "Nova – VM is created in spite of the fact that used port is missing fixed IP" [High,New] - Assigned to rhos-maint | |
| 15:45:20 | sean-k-mooney | gibi: by the way this might be of interest to you https://bugzilla.redhat.com/show_bug.cgi?id=1895702 | |
| 15:46:05 | openstackgerrit | Merged openstack/nova master: doc: Update the PTL guide https://review.opendev.org/c/openstack/nova/+/762727 | |
| 15:46:38 | sean-k-mooney | kashyap we might want to combine these or at least cross link them | |
| 15:47:01 | gibi | sean-k-mooney: interesing edge case where nova allows booting without IP | |
| 15:47:24 | kashyap | sean-k-mooney: So ... the ideal person to help debug this would be Stefan (he's on PTO), who is the 'virtio-blk' expert | |
| 15:47:26 | sean-k-mooney | gibi: ya i think its actully a neutron bug but you were asking about could we enable that behavior | |
| 15:47:46 | kashyap | That said, bugs like these, deep in the bowels of QEMU, require a debug QEMU with probes installed in the environment ... | |
| 15:47:52 | gibi | sean-k-mooney: yes, I got asked about it internally | |
| 15:48:03 | kashyap | ... and pray to the JuJu at the bottom of the sea that the bug reproduces | |
| 15:48:06 | sean-k-mooney | kashyap: if it starts blocking the ci then we will need to take more imediate action but until then i think it can wait till they are back form pto | |
| 15:48:37 | kashyap | sean-k-mooney: I highly doubt it can "block"; I just read Dave's explanation on the rare occurrence it can hit | |
| 15:48:45 | kashyap | As the last known occurrence in the CI seems to be 3 years ago | |
| 15:49:02 | kashyap | (But I'll comment further in the bug) | |
| 15:49:30 | gibi | yeah, i have no problem ignoring this qemu issue if it happens once in two years | |
| 15:50:01 | sean-k-mooney | yep same | |
| 15:50:15 | sean-k-mooney | we just know that it can fail this way | |
| 15:50:18 | kashyap | sean-k-mooney: Also, what's happening in the guest? | |
| 15:50:32 | kashyap | Is it just a garden-variety CirrOS instance just idling? | |
| 15:50:35 | sean-k-mooney | its just a migtrion of a cirror guest | |
| 15:50:41 | sean-k-mooney | yep | |
| 15:51:20 | sean-k-mooney | so beyound the ocational dhcp request or other idel work it should be doing nothing most of the time | |
| 15:54:55 | kashyap | sean-k-mooney: Dave says if it's a migrate-during-a-reboot, it could be a potential problem | |
| 15:54:58 | kashyap | That said ... | |
| 15:55:38 | kashyap | sean-k-mooney: gibi: I learn from Dave that we get that "guest index inconsistent" error when the migrated RAM is inconsistent with the migrated 'virtio' device state. | |
| 15:55:44 | kashyap | And a common case is where a 'virtio' device does an operation after the vCPU is stopped and after RAM has been transmitted. | |
| 15:55:52 | kashyap | (I'll add a comment in the bug from 2018 with notes) | |
| 15:58:22 | gibi | kashyap: thanks | |
| 16:10:36 | stephenfin | bauzas: Think you could take a look at this this week? https://review.opendev.org/c/openstack/nova/+/756549 | |
| 16:10:49 | bauzas | stephenfin: sure, will look | |

| 16:50:11 | kashyap | gibi: sean-k-mooney: I've outlined some notes here after my chat with QEMU migration maintainer, FWIW: https://bugs.launchpad.net/nova/+bug/1737625/comments/4 | |
| 16:51:03 | sean-k-mooney | kashyap: we might want to use the other bug | |
| 16:51:13 | sean-k-mooney | and close that as a duplicate | |
| 16:51:35 | kashyap | sean-k-mooney: Isn't this more accurate? It is talking about 'virtio-blk' and the Gate issue also is virtio-blk | |
| 16:51:44 | openstack | Launchpad bug 1761798 in OpenStack Compute (nova) "live migration intermittently fails in CI with "VQ 0 size 0x80 Guest index 0x12c inconsistent with Host index 0x134: delta 0xfff8"" [Medium,Confirmed] | |

| 19:12:20 | sean-k-mooney | stephenfin: ah those are related to xenapi removal | |
| 19:16:50 | sean-k-mooney | i tought it was related to the compute_monitors config intially | |
| 19:16:57 | sean-k-mooney | https://github.com/openstack/nova/blob/120d866df7ab81b666c0e43b97705a90483533bc/nova/conf/compute.py#L107-L126 | |
| 19:24:02 | sean-k-mooney | stephenfin: by the way we talked about the metrics weigher and weighing on things that were not compute weights in the past | |
| 19:24:06 | sean-k-mooney | https://github.com/openstack/nova/blob/master/nova/compute/monitors/__init__.py#L40-L48 | |
| 19:24:17 | sean-k-mooney | the monitors are a stevaldor entry point | |
| 19:24:30 | sean-k-mooney | and the numa memory bandwtih ones were actully plugins not in tree | |
| 19:24:57 | sean-k-mooney | https://github.com/openstack/nova/blob/c250aca00ba89b6fad86bfaebb3083e9f5c55f3b/nova/compute/monitors/__init__.py#L44 the doc used to reference them years ago | |
| 19:28:43 | sean-k-mooney | well it was propsoed upstream https://review.opendev.org/c/openstack/nova/+/270344 | |
| 19:28:53 | sean-k-mooney | but it was not merged | |
| 19:31:20 | sean-k-mooney | https://review.opendev.org/c/openstack/nova-specs/+/180983 was the spec | |
| 21:21:27 | sean-k-mooney | gibi: stephenfin i just realised that https://review.opendev.org/c/openstack/nova/+/653506 is still not merged but its been so long that i have lost most of the context. its still proably should be fixed but im not sure when ill get to it. hopefully soon but i tought this was merged years ago... | |
