| 10:48:21 | bauzas | guys, please welcome our master branch that's now a Dalmatian :) | |
| 10:48:46 | bauzas | so long Caracal and thanks for the fish | |
| 10:49:14 | bauzas | (RC1 tag is set and caracal branch created) | |
| 10:53:25 | gibi | bauzas: \o/ | |
| 11:15:46 | sean-k-mooney | :) | |
| 12:00:53 | opendevreview | Fabian Wiesel proposed openstack/nova master: Do not close returned image-chunk iterator & get_verifier early https://review.opendev.org/c/openstack/nova/+/909474 | |
| 13:18:57 | fwiesel | bauzas: I've reopened the bug #2055700 as #2058225. In my mind _rebuild_default_impl is implemented libvirt specific. I can implement driver.rebuild for vmwareapi to work around the bug, but I don't think that would be a great way forward. | |
| 13:21:03 | opendevreview | Merged openstack/nova stable/2023.2: Power on cores for isolated emulator threads https://review.opendev.org/c/openstack/nova/+/913195 | |
| 13:40:59 | bauzas | fwiesel: cool | |
| 13:44:52 | fwiesel | But I do not know enough how it is supposed to work in libvirt to make a good suggestion on how to implement it differently. I mean, I assume it makes sense that it is implemented the way it is. | |
| 13:53:08 | bauzas | fwiesel: you're referring to https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L4132-L4137 | |
| 14:00:25 | bauzas | fwiesel: _rebuild_default_impl is a virt-agnostic solution for rebuild which does delete the old guest and then create a new one https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3648-L3731 | |
| 14:02:52 | gibi | elodilles: thanks for the reviews so far. the parent of https://review.opendev.org/c/openstack/nova/+/913196 is merged now. So when you have time please check this backport too | |
| 14:02:56 | bauzas | as you can read, we power off the guest, detach its volumes, (reimage the root disk if volume-backed), destroy the guest, attach the volumes again and spawn the guest | |
| 14:14:52 | sean-k-mooney | fwiesel: the way its currently implemtned shoudl wor for vmware too | |
| 14:15:22 | sean-k-mooney | fwiesel: the only driver that does anythign custom is ironic | |
| 14:16:09 | sean-k-mooney | the vmware dirver can provide its own solution | |
| 14:17:43 | elodilles | gibi: ACK, will do | |
| 14:18:44 | sean-k-mooney | the imporant thing to remember about rebuild is rebuild is not a move operations, evacuate is a rebuild to a diffent host but by default a normal rebuild shoudl never change host. if you change image however you do need to call the schduler with the current host adn the existin flavor and new iamge to confirm that host is valid. that should all be handeled for you in the | |
| 14:18:46 | sean-k-mooney | generic compute manager code so the only thing the driver level rebuidl needs to do is ensure the root disk is reimaged | |
| 14:19:35 | sean-k-mooney | if there is a more effiecnt way to do that in vmware then the generic approch then that is fine to use | |
| 14:20:05 | dansmith | not "should never change host" but "does not change host" | |
| 14:20:14 | dansmith | even the driver shouldn't be able to override that | |
| 14:22:08 | sean-k-mooney | right | |
| 14:22:31 | sean-k-mooney | im just tyring to say that if there was to be a vmware version fo rebuidl in the vmware driver the only thing it should od is reimage the disk | |
| 14:22:47 | sean-k-mooney | the vm must remain on the same hypervior host | |
| 14:23:14 | sean-k-mooney | i just mentioned evcautate because the driver code will have to work when called in that code path too | |
| 14:23:26 | dansmith | yep | |
| 14:27:56 | fwiesel | sean-k-mooney: The current implementation calls driver.destroy, and *then* calls detach volume. In my mind, that shouldn't work in the general case. | |
| 14:33:03 | bauzas | no | |
| 14:33:13 | bauzas | fwiesel: https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3675-L3676 | |
| 14:33:44 | bauzas | poweroff, detach, destroy is the workflow | |
| 14:34:38 | fwiesel | Destroy: https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3695-L3701 and then via https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3713-L3715 comes https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3589-L3595 | |
| 14:35:43 | fwiesel | bauzas: The root volume is being detached after the instance has been destroyed if reimage_boot_volume and is_volume_backed | |
| 14:36:26 | fwiesel | So, poweroff, detach everything except the root-disk, destroy, detach the root_disk (in the case of reimage_boot_volume and is_volume_backed) | |
| 14:36:31 | bauzas | we still detach the volumes, including the root bdm in https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3675-L3676 | |
| 14:37:49 | fwiesel | Sure, and after the desotry the _rebuild_volume_backed_instance -> _detach_root_volume | |
| 14:40:39 | fwiesel | Well, we have `reimage_boot_volume=True` ergo `detach_root_bdm = not reimage_boot_volume = False`, so `detach_block_devices(..., detach_root_bdm=False)`. | |
| 14:51:09 | bauzas | fwiesel: ah you're right, it's a bool | |
| 14:51:25 | bauzas | okay, so the root volume isn't detached yet, my bad | |
| 14:53:24 | bauzas | and ack, we rebuild the root volume in _rebuild_volume_backed_instance() | |
| 14:55:26 | bauzas | where we detach the volume, delete the old attachment, and then reimage the volume thru cinder | |
| 14:56:13 | bauzas | interestingly enough, we destroy the guest indeed before the detach, but we skip its bdm when we call the driver destroy | |
| 15:06:15 | fwiesel | There is probably a reason for that. I mean it is done very explicitly so. But as I said, I don't have any idea why. | |

| 16:09:24 | bauzas | anything to discuss about the gate ? | |
| 16:09:27 | bauzas | oh, one point | |
| 16:09:48 | bauzas | I just saw slaweq's email on bare rechecks | |
| 16:10:01 | Uggla | o/ | |
| 16:10:22 | bauzas | as a reminder, please avoid to say only "recheck" when you have a gate failure | |
| 16:10:38 | dansmith | or "recheck unrelated" | |
| 16:10:45 | bauzas | and please add a good comment explaining what's the root problem | |
| 16:10:47 | dansmith | it can be unrelated, but at least say why | |
