| 04:25:13 | pvc | hi | |
| 04:25:17 | pvc | how can i hide kvm for gpu ? | |
| 04:25:23 | pvc | so i can test it | |
| 04:28:24 | pvc | gibi | |
| 04:28:28 | pvc | how can i hide the hypervisor | |
| 04:28:30 | pvc | ? | |
| 04:34:46 | melwitt | mriedem_away: fyi I just added your neutron new port binding API to a runway. I skipped "report CPU features as traits" because the last -1 was 7 days ago with no response from the author | |
| 04:35:09 | melwitt | naichuans: fyi your blueprint xenapi-image-handler-option-improvement has been added to a runway again | |
| 04:36:15 | melwitt | naichuans: also, feel free to add feedback about your experience with vgpu-rocky in runway at L186 https://etherpad.openstack.org/p/nova-runways-rocky as it's been moved out of a runway | |

| 08:40:09 | pvc | i have an instance with GPU on it but my hypervisor is always restarting and i dont know why | |
| 08:48:28 | openstackgerrit | Merged openstack/nova master: api-ref: mention that you can't re-parent a resource provider https://review.openstack.org/572501 | |
| 08:48:35 | openstackgerrit | Merged openstack/nova master: Fix some inconsistencies in doc https://review.openstack.org/570407 | |
| 08:52:43 | pvc | can anyone help me | |
| 09:01:15 | mdbooth | Can anybody remind me which repo the ci job definitions are in? | |
| 09:05:18 | kashyap | mdbooth: "project-config", IIRC | |
| 09:06:18 | kashyap | Maybe it's this, since upstream has moved to Zuul a while ago: https://github.com/openstack-infra/openstack-zuul-jobs | |
| 09:08:24 | kashyap | mdbooth: Yes, the above is the repo. From its description: | |
| 09:08:25 | kashyap | edit these files to make configuration changes to OpenStack | |
| 09:08:25 | kashyap | project-template definitions for the OpenStack project. You should | |
| 09:08:25 | kashyap | OpenStack project CI system Zuul. It also contains job and | |
| 09:08:25 | kashyap | This repo contains a set of ansible playbooks which are used by the | |
| 09:08:27 | kashyap | Infrastructure CI. | |
| 09:08:52 | mdbooth | kashyap: Thanks. I'll take a look. | |
| 09:14:39 | lyarwood | kashyap: http://logs.openstack.org/33/571433/2/gate/legacy-tempest-dsvm-neutron-full/a007290/logs/screen-n-cpu.txt.gz?#_2018-06-06_04_56_16_327 - if you have anytime this morning would you mind looking over this cold snapshot failure, appears we can't resume the paused/saved domain but I can't see a clear reason why in the libvirtd logs. | |
| 09:15:00 | lyarwood | kashyap: https://review.openstack.org/#/c/571433/2 is the change FWIW | |
| 09:15:44 | kashyap | lyarwood: Hi, will look | |
| 09:29:38 | jangutter | sahid: Thanks for taking a look at https://review.openstack.org/567148 . I agree that there's "duplicate" info passed through for VIFHostDevice, but at least it's consistent with other VIF's. I think it has to do with the distinction between the VIF objects and the VIFPortProfile objects. | |
| 09:31:31 | jangutter | sahid: The os-vif VIF describes "how to wire it into the VM". The os-vif port-profile describes "how to wire it into the datapath". Because the distinction is not particularly clear with libvirt, there's some muddy overlap. | |
| 09:33:47 | openstackgerrit | Bhagyashri Shewale proposed openstack/python-novaclient master: Modify novaclient to support basic attributes https://review.openstack.org/572285 | |
| 09:38:11 | kashyap | lyarwood: Meta comment: The libvirt debug log on the URL is supposedly: 3.2M. But my download of it is still running beyond 7MB | |
| 09:38:38 | kashyap | Maybe `wget` extracts it downloads | |
| 09:40:59 | kashyap | The full download (on a remote machine) was: 47M :-) | |
| 09:46:57 | mdbooth | kashyap: I'm looking at the libvirt logs from this multiattach job: http://logs.openstack.org/58/567258/5/check/nova-multiattach/d23fad8/logs/libvirt/libvirtd.txt.gz | |
| 09:47:25 | mdbooth | Specifically I'm trying to see what goes on during the successful multiattach swap volume test | |
| 09:49:23 | mdbooth | It looks like the drive of interest is added around 2018-06-04 10:56:57.865+0000 | |
| 09:49:55 | kashyap | Can you tell the drive ID? | |
| 09:50:09 | mdbooth | drive-virtio-1 | |
| 09:50:09 | kashyap | Is it? 'drive-virtio-disk1' | |
| 09:50:38 | mdbooth | I'm slightly confused, because I don't see shared in the 'human-monitor-command' | |
| 09:51:02 | kashyap | I don't see a "drive-virtio-1". Did you mean: 'drive-virtio-disk1'? | |
| 09:51:21 | mdbooth | But there is "share-rw":"on" in what seems to be sent to qemu | |
| 09:51:23 | mdbooth | kashyap: Yeah | |
| 09:51:27 | kashyap | libvirt uses QMP (the JSON RPC) with QEMU. Not HMP. (only rarely) | |
| 09:51:49 | kashyap | 2018-06-04 11:13:18.158+0000: 32308: debug : qemuMonitorJSONCommandWithFd:301 : Send command '{"execute":"device_add","arguments":{"driver":"virtio-blk-pci","scsi":"off","bus":"pci.0","addr" | |
| 09:51:49 | kashyap | Yes: | |
| 09:51:53 | kashyap | :"0x6","share-rw":"on","drive":"drive-virtio-disk1","id":"virtio-disk1"},"id":"libvirt-20"}' for write with FD -1 | |
| 09:52:16 | mdbooth | Right, so that's 'shared', right? | |
| 09:52:25 | kashyap | mdbooth: Yes. And libvirt will _not_ migrate it. | |
| 09:52:28 | mdbooth | i.e. it's multiattach | |
| 09:52:36 | kashyap | Here is the libvirt source itself saying as such: | |
| 09:52:37 | kashyap | 291 !virStorageSourceIsEmpty(disk->src); | |
| 09:52:37 | kashyap | 290 return !disk->src->shared && !disk->src->readonly && | |
| 09:52:37 | kashyap | 289 * with source */ | |
| 09:52:37 | kashyap | 288 /* Default is to migrate only non-shared non-readonly disks | |
| 09:52:39 | kashyap | 292 } | |
| 09:52:42 | kashyap | 293 | |
| 09:52:51 | mdbooth | kashyap: Except that it does | |
| 09:53:12 | mdbooth | Keep searching down on that disk id | |
| 09:53:49 | mdbooth | 2018-06-04 10:57:05.201+0000 | |
| 09:53:53 | mdbooth | It does a drive mirror | |
| 09:54:18 | mdbooth | This isn't live migration, btw | |
| 09:54:24 | mdbooth | This is volume migration | |
| 09:54:52 | mdbooth | So the data in volume a is moved to volume b and a is seamlessly substituted for b in the domain | |
| 09:55:26 | kashyap | mdbooth: Hang on -- | |
| 09:55:29 | mdbooth | So it looks like this version of qemu/libvirt at least does permit drive mirror of a shared disk | |
| 09:55:36 | kashyap | The `drive-mirror` is done fir 'disk0' | |
| 09:55:39 | kashyap | s/fir/for/ | |
| 09:55:50 | kashyap | 2018-06-04 10:59:30.956+0000: 32306: debug : qemuMonitorJSONCommandWithFd:301 : Send command '{"execute":"drive-mirror","arguments":{"device":"drive-virtio-disk0","target":"/opt/stack/data/n | |
| 09:55:55 | kashyap | ova/instances/snapshots/tmpQeWSxD/8d2e75dbf0a4466fb31f11ca06a21a96.delta","sync":"top","mode":"existing","format":"qcow2"},"id":"libvirt-28"}' for write with FD -1 | |
| 09:56:16 | mdbooth | kashyap: That's much later | |
| 09:56:21 | mdbooth | Different operation | |
| 09:56:27 | mdbooth | Look at 2018-06-04 10:57:05.201+0000 | |
| 09:57:02 | kashyap | mdbooth: Okay, I seem to have misread the code :-( | |
| 09:57:07 | kashyap | mdbooth: libvirt _doesn't_ forbid | |
| 09:58:50 | pvc | hi | |
| 09:59:32 | kashyap | mdbooth: So libvirt should _not_ forbid because, the said shared disk might be in use at any given point. | |
| 09:59:45 | kashyap | But probably that's what you were trying to tell me. | |
| 10:00:05 | mdbooth | kashyap: Actually I think it *should* forbid it, but doesn't | |
| 10:00:11 | pvc | kashyap | |
| 10:00:25 | pvc | can help me with gpu instnace? | |
| 10:00:26 | kashyap | mdbooth: libvirt developer says the above reason is why it shouldn't forbid it | |
| 10:00:27 | mdbooth | Although... meh it should probably give us the rope to hang ourselves with | |
| 10:00:48 | kashyap | pvc: Hi, in the middle of something. Please ask such questions to the operators list or ask.openstack.org | |
| 10:01:09 | kashyap | (And I don't know the answer to it, top off my head) | |
