| 12:50:19 | sean-k-mooney | you can also configure passthough of the host cache info but we dont do that in nova today | |

| 12:53:07 | rmart04 | Ah, ok so possible in Libvirt/KVM but not exposed to nova? | |

| 12:55:19 | rmart04 | Interesting, is there anyway to add config like this that will persist? Or is it a case of modifying the XML and rebooting the VM in nova and when its trashed, start again? | |

| 12:55:39 | sean-k-mooney | not without modifying the nova code to add it no | |

| 12:56:30 | sean-k-mooney | this is proably something we could add as a feature but its never really come up | |

| 14:19:29 | openstackgerrit | Tobias Urdin proposed openstack/nova master: When Nova-Api runs behind the load balancer or Reverse proxy, Loadbalancer IP is getting logged in nova_api.log instead of end user source ip by RequestLog https://review.opendev.org/c/openstack/nova/+/786766 | |

| 16:51:35 | sean-k-mooney | dansmith: artom how we are fixing this for them is having them change all the config value to lowercase to match what neturon is expecting. and then doing a db update of all the things | |

| 16:52:28 | dansmith | yeah, I like the hardening of course, but in the interim we have to provide them a way to migrate and fix, since we don't control rabbit | |

| 16:53:00 | dansmith | so either we say "don't change it once you've set it" (which seems reasonable to me) or we say we're going to change everybody, so get your homework done (also reasonable) | |

| 16:53:20 | dansmith | if neutron is making some change that is going to require consistency then presumably the latter is the only option | |

| 16:59:48 | bauzas | I don't have a particular opinion on how we should fix those RPC issues, but I'm frightened by us trying to change the queue names | |

| 17:03:04 | sean-k-mooney | well we can have this just be a workaround config option and never enable it by default | |

| 17:15:25 | dansmith | sean-k-mooney: artom: We could probably lower() the hostname on service.create() and not service.update() in the short term | |

| 17:15:43 | dansmith | that won't fix the cell mapping issue, but sounds like that's not the primary concern (or the biggest impact) | |

| 17:21:41 | sean-k-mooney | dansmith: althougy we would have to ensure that compute agents used the host value form the service record not form the config when settin up rpc | |

| 17:23:55 | sean-k-mooney | im not actully sure where that happens i was expecting to see it here but here https://github.com/openstack/nova/blob/master/nova/cmd/compute.py but i guess its elsewhere | |

| 17:34:37 | dansmith | right, | |
| 17:34:55 | dansmith | I'm saying that (a) instance.host has to be kept to match service.hostname, so we can't change one without the other | |
