| 15:01:04 | dansmith | sean-k-mooney: yeah that might be a thing, but we're also legitimately timing out a lot of jobs, so I'm concerned about slowing anything down with a memory boost causing more of those | |
| 15:01:10 | sean-k-mooney | https://www.omgubuntu.co.uk/2022/01/ubuntu-on-raspberry-pi-4-2gb-zswap | |
| 15:01:33 | dansmith | if we're thrashing I think it will slow us down a lot, if we're stashing bloat we never reference, then it will help | |
| 15:01:43 | sean-k-mooney | once we swap to 22.04 it will be better | |
| 15:01:46 | bauzas | and I suspect this may be related | |
| 15:01:59 | dansmith | sean-k-mooney: what will? | |
| 15:02:31 | sean-k-mooney | dansmith: its much simpler to enable zswap in 22.04 | |
| 15:02:35 | dansmith | oh | |
| 15:02:39 | sean-k-mooney | and they did some performace optiomistaions | |
| 15:02:46 | sean-k-mooney | https://waldorf.waveform.org.uk/2021/6-months-with-the-pi-desktop.html | |
| 15:02:49 | dansmith | but still, you're trading cpu for memory | |
| 15:03:05 | sean-k-mooney | cpu vs disk io performace really | |
| 15:03:07 | dansmith | and right now in addition to running against the memory barrier, we're also running against the cpu barrier | |
| 15:03:27 | sean-k-mooney | compression effectivly makes it like swappign to faster storage | |
| 15:03:37 | sean-k-mooney | if you have the cpu to do it | |
| 15:03:56 | dansmith | sure, if you're io constrained it will help there, but it's all trading for cpu | |
| 15:04:07 | sean-k-mooney | yep | |
| 15:04:26 | sean-k-mooney | i looked into this a while ago when those blogs first came out | |
| 15:04:36 | sean-k-mooney | it proably worth doing an expermient with at least | |
| 15:05:05 | dansmith | yeah, any shorter but fatter jobs will benefit from it for sure, and it could reduce our own noisy neighbor effects | |
| 15:05:06 | sean-k-mooney | honestly just moving to 16G vms in ci woudl be the better solution | |
| 15:05:13 | sean-k-mooney | but since that is not really an option | |
| 15:05:27 | dansmith | I'm just worried about slowing the tests down at all because we're already hitting widespread legit timeouts | |
| 15:05:30 | dansmith | on slower nodes | |
| 15:05:44 | sean-k-mooney | ya which is a concern | |
| 15:08:00 | sean-k-mooney | wow gerrit found https://review.opendev.org/c/openstack/devstack/+/828639 becasue i mention zswap in my last comment on the top level | |
| 16:46:35 | darkhorse | Hi team - I read about service tokens in cinder documentation which is really cool. Can service tokens be used in nova and other services too? | |
| 17:08:41 | dansmith | wow, the nova-next mysql patch passed check the first time through | |
| 17:08:54 | dansmith | bauzas: sean-k-mooney ^ | |
| 17:39:04 | dansmith | melwitt: is this something you saw in the gate? https://review.opendev.org/c/openstack/nova/+/875991 | |
| 17:39:13 | dansmith | I don't see that error message in opensearch | |

| 07:09:56 | gibi | yeah the revert finally merged | |
| 07:20:34 | gibi | I've updated the release patch | |

| 21:05:36 | jrwr | There is a possible bug I've discovered in Zed version of Nova, With Kernel 6.0, Openstack Kolla, and a AMD EYPC 7702, I've ran into a issue with the hyper-v enlightenment that where enabled as of late, | |
| 21:06:28 | jrwr | qemu is throwing errors causing instance creation failures, "qemu-kvm: Hyper-V enlightened VMCS (hv-evmcs) is not supported by kernel" and "qemu-kvm: warning: This feature depends on other features that were not requested: CPUID.8000000AH:EDX.svme-addr-chk [bit 28]" | |
| 21:07:37 | jrwr | /sys/module/kvm_amd/parameters/nested is reporting "1" showing that it should be supported here | |
| 21:21:13 | jrwr | "qemu-system-x86_64 --nographic -cpu host,hv_relaxed,hv_vapic,hv_spinlocks=8191,hv_vpindex,hv_runtime,hv_synic,hv_stimer,hv_reset,hv_frequencies,hv_time,hv_evmcs --enable-kvm" will throw the same error on local system | |
| 21:21:39 | jrwr | Its a Unsupported CPU flag on AMD Processors, Making Zed Release Intel only! | |
| 21:59:49 | jrwr | Filed a bug on it https://bugs.launchpad.net/nova/+bug/2009280 | |

| 07:29:41 | samuelkunkel[m] | Hi Guys, we have build a regressiontest for https://bugs.launchpad.net/nova/+bug/2007697. Shall I rebase my current Merge Request or open a new one just for the regressiontest? | |
| 07:30:31 | samuelkunkel[m] | As I saw in the comments that it is to reproduce the bug - so I need to remove „the fix“ from the merge request then | |
| 08:16:50 | sahid | o/ | |
| 09:05:07 | bauzas | breaking news : since 2 mins, master branch is officially for Bobcat \o/ | |
| 09:05:22 | bauzas | kudos to the nova team which worked hardly in Antelope | |
| 09:05:36 | bauzas | gibi: thanks for having reproposed the RC1 patch | |
| 09:07:49 | kashyap | :) | |
| 09:14:16 | frickler | bauzas: hardly means the opposite of hard to me, pretty sure you didn't want to say that? ;) | |
| 09:15:44 | kashyap | frickler: Hehe, he indeed meant "worked hard" :) | |
| 09:15:51 | bauzas | hah | |
| 09:16:00 | bauzas | yeah sorry | |
| 09:16:23 | kashyap | English is terrible in that. You can say it "softly", but you can't say it "hardly" (you say it "harshly"). :) | |
| 09:16:27 | bauzas | hardly in French means something better | |
| 09:16:55 | bauzas | but yeah actually I know about english hardly | |
| 09:17:14 | bauzas | like "I hardly accepted this" | |
| 09:17:30 | bauzas | which means "I wasn't really happy with this" | |
| 09:17:54 | bauzas | like in French, it should be something like " I was happy with this" | |
| 09:18:44 | frickler | yes, I guess every language has its own set of pitfalls like that | |
| 09:19:22 | bauzas | like "eventually" in French means something different :p | |
| 09:20:10 | bauzas | if you want "I would eventually want to see you", that's not saying you will see him/her at the end of the time | |
| 09:20:44 | frickler | ah, probably that's like "eventuell" in German then | |
| 09:20:48 | bauzas | it would rather say "I could maybe see you but I don't know yet if I want it :p" | |
| 09:21:55 | frickler | but that would translate the same | |

| 09:25:42 | frickler | oh, that's even almost the same spelling in French, éventuel? | |
| 09:27:35 | gibi | o/ happy Bobcat day then | |
| 09:35:40 | bauzas | frickler: indeed | |
| 09:35:54 | bauzas | frickler: we share a few common words between German and French | |
| 09:36:20 | bauzas | that being said, English is full of words that very sound like French but written a bit differently | |
| 09:37:16 | bauzas | like "individuellen" in German means exactly the same in French :) | |
| 09:38:36 | bauzas | coming straight from Latine "individus" | |
