| 15:25:11 | TheJulia | oh? | |
| 15:25:27 | sean-k-mooney | https://docs.openstack.org/nova/latest/configuration/config.html#DEFAULT.max_concurrent_builds | |
| 15:25:35 | sean-k-mooney | max concurent builds | |
| 15:25:43 | sean-k-mooney | its a compute agent config | |
| 15:26:08 | johnthetubaguy | until recent releases, the scheduler used to fall over first though, in theory better now, but hope to be testing that more soon | |
| 15:26:10 | sean-k-mooney | so you could set that per ironic conpute service | |
| 15:26:28 | sean-k-mooney | johnthetubaguy: multi create still sucks | |
| 15:26:42 | sean-k-mooney | johnthetubaguy: it has less races with plamcnet | |
| 15:27:00 | sean-k-mooney | but unless we change how retires work anti affingity server groups break things | |
| 15:27:14 | TheJulia | sean-k-mooney: I feel like it works, but I'm wondering if someone has that set to like 100... | |
| 15:27:19 | TheJulia | I guess I need more information | |
| 15:28:15 | sean-k-mooney | TheJulia: in the ironic case there is going to be one hell of a power spike too | |
| 15:28:29 | sean-k-mooney | 1000 servers booting at once | |
| 15:29:28 | TheJulia | sean-k-mooney: some people have the power for this | |
| 15:33:36 | sean-k-mooney | TheJulia: yep but i once rebooted half the server on a rack and triped its local breaker | |
| 15:33:43 | sean-k-mooney | that was fun... | |
| 15:33:55 | TheJulia | yeaaaah | |
| 15:34:05 | TheJulia | Been there, I really overengineered power for every rack I built | |
| 15:34:52 | sean-k-mooney | that was when we discover the electian that install it connected it to the wrong ups and it was signifcaly more over subsribed then the lab team tought | |
| 15:35:09 | sean-k-mooney | the 3 new rack were all on the old ups not the new one in the room next door | |
| 15:35:56 | sean-k-mooney | as a result i was not allowed to power them back on until we got someone in to swap them | |
| 16:08:03 | TheJulia | I'm suddenly reminded of the one time I literally burned out a breaker | |
| 16:08:40 | johnthetubaguy | sean-k-mooney: yeah, anti affinity totally breaks things still, +1 that | |
| 16:09:18 | sean-k-mooney | its because we calusate the alternitive host up front so once one thing files and retire it can cause another thing to fail | |
| 16:09:39 | johnthetubaguy | it gets worse with PCI passthrough | |
| 16:09:48 | johnthetubaguy | or seems to | |
| 16:09:56 | sean-k-mooney | so unless we call the sculder again instead when we do the retry your screwed | |
| 16:10:04 | sean-k-mooney | johnthetubaguy: yes it will | |
| 16:10:58 | sean-k-mooney | johnthetubaguy: that just because we dont track the pci device in placment so when we claim the new candiate we dont calim the pci device and that can cause a reschdule | |
| 16:11:08 | johnthetubaguy | ack | |
| 16:11:20 | sean-k-mooney | johnthetubaguy: we dont need placement to fix that we could allocate the deivce in the conductor be we dont today | |
| 16:12:35 | sean-k-mooney | the pci devices table has 3 states available allocated and claimed i think and the difference between the last too is one is a reservation for a vm that has not yet been created on the host and the other is for when the vm is actully using it | |
| 16:12:52 | johnthetubaguy | oh my... custom resources using the provider yaml totally helps with those races, I think | |
| 16:13:07 | sean-k-mooney | it could | |
| 16:13:21 | sean-k-mooney | but we have no way to associate the RPs with the pci devcices | |
| 16:13:27 | sean-k-mooney | so its close but wont work | |
| 16:13:32 | sean-k-mooney | at least not today | |
| 16:13:42 | johnthetubaguy | because we pick the specific one too early? | |
| 16:14:08 | sean-k-mooney | no we pick the specific on on the compute node but that code has no knolage of placment | |
| 16:14:19 | sean-k-mooney | so it would not pick form the device claimed in palcment | |
| 16:14:25 | sean-k-mooney | it would pick form all devices on the host | |
| 16:15:05 | johnthetubaguy | anyways, I think it fixes a case I am worried about, but we haven't merged that feature (must review that again soon) | |
| 16:17:00 | sean-k-mooney | it will fix it for anything that is not manage by nova direclty | |
| 16:17:09 | sean-k-mooney | like cache allocation | |
| 16:17:35 | sean-k-mooney | or power/termal based scudling | |

| 12:44:53 | lvdombrkr | hello guys, trying to inject admin_password (inject_password=true ) into image but when creating instance get this error in nova-compute.log | |

| 12:45:14 | lvdombrkr | Train + Centos8 | |
| 12:45:33 | lvdombrkr | looks something with related with pytho3 | |
| 12:45:41 | lvdombrkr | any clues? | |
| 13:55:36 | lvdombrkr | guys anyone here? | |
| 16:06:02 | frickler | lvdombrkr: that part of nova code seems never to have worked with python3 and is also lacking proper testing, I can reproduce on master, will try to get a patch up soon | |
| 16:12:33 | lvdombrkr | frickler: ok i see. thanks for detailed answer. do i need open bug in https://bugs.launchpad.net/nova/ | |

| 07:20:36 | bauzas | good morning Nova | |
| 07:30:43 | lvdombrkr | morning nova. is there other ways to inject password except inject_password=true ? | |
| 07:53:55 | gibi | bauzas: good morning | |
| 07:54:26 | gibi | lvdombrkr: you can use cloud init in the guest and you can use the config driver or the metadata service to provide input for cloud init | |
| 07:54:28 | bauzas | first time I don't feel jetlagged or fried after a PTG | |
| 07:55:01 | bauzas | gibi: didn't we deprecated password injection btw. ? | |
| 07:55:04 | gibi | bauzas: I don't miss the jetlag part of the PTG :) | |
| 07:55:26 | bauzas | gibi: next one, we won't have jetlag too | |
| 07:55:27 | bauzas | :) | |
| 07:55:39 | gibi | bauzas: I think we did https://blueprints.launchpad.net/nova/+spec/deprecate-file-injection | |
| 07:55:58 | gibi | ohh this is file injection not password injection | |
| 07:56:42 | lvdombrkr | gibi: thanks for answer. but if i will use metadata, then passwortd will be stored in metadata in plain text, right? | |
| 07:56:51 | bauzas | ah my bad | |
| 07:57:12 | bauzas | I remembered we did deprecated some injection, but like you, it was the wrong way | |
| 07:58:04 | gibi | lvdombrkr: you can inject public keys | |
| 07:58:42 | lvdombrkr | gibi: yes yes about public keys i know, but i need excatly password | |
| 07:58:58 | bauzas | lvdombrkr: question, why can't you use a config tool like Ansible for injecting such things if you don't wanna use the tool we provide ? | |
| 07:59:52 | frickler | bauzas: because it is broken? see https://launchpad.net/bugs/1882421 | |
| 07:59:52 | openstack | Launchpad bug 1882421 in OpenStack Compute (nova) "inject_password fails with python3" [Undecided,In progress] - Assigned to Dr. Jens Harbott (j-harbott) | |
| 08:00:12 | lvdombrkr | bauzas: i want use config you provided (inject_password) but its not working with Centos8 Python3 | |
| 08:00:13 | bauzas | frickler: ah, gtk | |
| 08:00:57 | bauzas | then, I'd recommend to go thru external tools until it's fixed | |
| 08:03:29 | bauzas | frickler: I can take a look at your change if you will | |
| 08:03:38 | lvdombrkr | bauzas frickler : thanks for answers. how long time can take fix this? | |
| 08:06:56 | gibi | bauzas, lvdombrkr, frickler: I'm reviewing the fix now (while on a parallel phone meeting so it will take time) | |
| 08:10:29 | lvdombrkr | gibi bauzas frickler: perfect guys, keep me updated please :) | |
| 08:11:16 | gibi | lvdombrkr: sure | |
| 08:13:14 | aarents | good morning nova | |
| 08:13:27 | aarents | gibi: bauzas just FYI, I've made some stupid max attachement contest on a devstack with machine-type q35: | |
| 08:13:28 | gibi | aarents: good morning | |
| 08:13:34 | aarents | nova interface-list 6cc30912-c4ae-493d-8209-e19f16f101bc | grep -c ACTIVE | |
| 08:13:37 | aarents | 220 | |
| 08:13:45 | aarents | it is only possible because I override in code num_pcie_ports.max to 224 instead of 28 (we force max to 28 because of limitation with aarch64/virt), without doing it max attachment on q35 is 24 (28 - 4 reserved) and on pc it is 26, so we are still better on pc than on q35 regarding max attachement with current code. | |
