| 10:40:55 | kashyap | viks____: I have just asked your question to a QEMU dev on your "write perf better in guest than on host" question; I'll let you know if there's a response | |
| 10:41:30 | kashyap | (I asked the author of the earlier-mentioned benchmarking blog post.) | |
| 10:44:36 | viks____ | Ok.. thanks | |
| 10:48:59 | kashyap | viks____: So, here we go: | |
| 10:50:53 | kashyap | viks____: It's likely that the [host] page cache is being used, so host vs guest numbers could be wildly different to due different amounts of RAM. | |
| 10:51:09 | kashyap | viks____: So the first step is to check whether the benchmark is going through the page cache. If it does, then it's possible that the amount of physical disk I/O being done is quite different between guest and host, and therefore performance is also very different. | |
| 10:52:23 | kashyap | viks____: It's point-2 in the blog post abov ("Bypass the page cache"). You might want to re-test with 'fio' to compare and contrast. | |

| 11:55:44 | stephenfin | gibi: I corrected the docstring as requested at https://review.opendev.org/c/openstack/nova/+/764376/ fwiw | |
| 12:00:18 | priteau | Hello. I have an affinity server group, with a single instance in it. The instance is shut off. I can't cold migrate this instance, ServerGroupAffinityFilter is removing all hosts. Is this a known issue? | |
| 12:01:11 | priteau | I found https://bugs.launchpad.net/nova/+bug/1890065 but I am not sure it's the same problem, since it is about 2 instances being live migrated | |
| 12:01:11 | openstack | Launchpad bug 1890065 in OpenStack Compute (nova) "Impossible to migrate affinity instances" [Wishlist,Opinion] | |
| 12:58:07 | gibi | stephenfin: ack, looks good | |
| 12:59:20 | gibi | priteau: I think it is the general behavior is known, if you have instances in an affinity group then you cannot migrate them. (the power state does not matter either). The edge case when you have only one instance in the affinity group is not handled spcially. Do you have a use case where you need a single instance in an affinity group? | |
| 13:06:21 | priteau | gibi: I've encountered this while migrating every instance on an OpenStack cloud during a c7 to c8 migration, I don't know why the user set it up that way. I suppose one use case would be to a server group for all instances of a cluster, which could potentially scale down to 1. | |
| 13:09:09 | gibi | priteau: solving the migration problem generally is hard, as that needs a way to say ignore-the-affinity-rule-for-this-migration which is most probably means an API impact. The single instance case could be solved by always ignoring the affinity rule, so that is easier but I don't know that solving only the single instance case would really help much | |
| 13:09:52 | priteau | Agreed. | |
| 13:10:26 | priteau | On the advice of johnthetubaguy I temporarily changed the policy in the instance_group_policy table and reverted it after the migration. | |

| 13:56:38 | gibi | did anybody see pip error like "ERROR: Links are not allowed as constraints" I got hit by it recently in grenade https://39757d668f2e13d2ecb5-94a4d63114c603d5be2910eb980b9a2e.ssl.cf1.rackcdn.com/756894/3/check/grenade/fe26d2e/job-output.txt | |
| 14:02:31 | gibi | both grenade and grenade-multinode hits it | |
| 14:02:42 | gibi | this is from the same patch running the grenade-multinode https://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_57e/756894/3/check/nova-grenade-multinode/57ea016/logs/grenade.sh.txt | |
| 14:12:27 | gibi | it seems it is started happening a lot in the last hour or so http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22Links%20are%20not%20allowed%20as%20constraints%5C%22 | |
| 14:14:08 | jangutter | gibi: I was just about to start sending up signal flares! | |
| 14:14:21 | gibi | jangutter: thanks | |
| 14:14:45 | jangutter | gibi: happened to me too, I was working on stable/victoria and at first I thought I did something wrong. | |
| 14:17:31 | jangutter | best I can figure out: https://github.com/openstack/devstack/blob/master/inc/python#L386 <--- devstack has been using this method for ages now. I wonder if a pip update converted the warning to an error. | |
| 14:20:45 | gibi | yeah, that sound like a possibility | |
| 14:24:06 | jangutter | Removing that line (and the preceding backslash) seems to unblock it for me, but figuring out the consequences of that needs someone with a lot more experience on requirements, pip and the projects needs. | |
| 14:37:13 | gibi | hm, I cannot push to opendev gerrit now | |

| 14:52:40 | gibi | kashyap: no worries, Milestone 1 is this week but we only freeze specs at M2 | |
| 14:53:44 | kashyap | gibi: Ah, thank you. I didn't realize that spec-freeze is at M2. | |
| 14:54:40 | gibi | kashyap: M2 is spec freze M3 is feature freeze | |
| 14:55:06 | gibi | I guess in the past there was a time when we freezed specs at M1 but we don't do that in the last couple of cycles | |
