14:53:02 jkulik sean-k-mooney, thanks for clarifying that. we're misusing quota then, as we're doing invoices based on quota and then people end up being unable to use what they pay for, if the AZ gets full.
14:55:39 sean-k-mooney jkulik: is see quotas are seperate form the idea of reservations
14:56:06 sean-k-mooney e.g. a quota is a limit on how much reouces you can use not a reservation of resouces for you to use
14:59:21 jkulik sean-k-mooney, for billing purposes, both would have to be the same. the user should not be able to user more than they payed for. but I get you point, I think.
15:01:47 sean-k-mooney jkulik: but they would not normally be usign all there quota
15:02:04 sean-k-mooney so its only the same if they are billed by available capasity instead of usage
15:02:32 sean-k-mooney most clouds bill by usage not capasity unless its a dedicated install
15:02:40 jkulik sean-k-mooney, yeah, they're billed what they could in theory consume. not the actual consumption.
15:07:09 sean-k-mooney jkulik: ya so in that modely you would tipleicaly use one of the feature that allows you to reserve hosts for a given tenat and dedicate those hosts to that tenant of a group of tenatns
15:08:55 ikla How do I tell which virtual interface passes through to nova compute instance. I have a alias for a dual-port card that has 4 VF's per port totalling 8. How do I know which port is passed through since they are on different networks. My alias name is eth10g and it can do say eth10g:8 which would be all 8 VF's.
15:09:52 sean-k-mooney ikla: well as a starting point pci pasthough is not intended for use with nics that will connect to neutron netwroks
15:10:00 sean-k-mooney ikla: specificly via alias
15:10:22 sean-k-mooney but you can find out wich was allocated in two ways
15:10:56 sean-k-mooney either you can check the pci_devices tables
15:11:08 sean-k-mooney in the cell db
15:11:23 sean-k-mooney or you can look at the instance domain xml
15:11:27 sean-k-mooney so do virsh list

15:43:01 ikla Please ensure all devices within the iommu_group are bound to their vfio bus driver
15:43:06 ikla anyone seen that before?
15:43:23 sean-k-mooney yes
15:43:45 sean-k-mooney so you cant have diffenret VF bound to different direvers if they are in the same iommu group

08:51:26 lyarwood cool thanks
08:52:09 lyarwood stephenfin: ^ would you mind hitting that as well?
09:36:51 born2bake maybe any of you guys were struggling with that as well: I deployed stack via k-a(train). I wanted to test ScyllaDB but got errors message related to sse4.2 and clmul instruction set. I ve raised an issues here https://github.com/scylladb/scylla/issues/6528 and been told that "you have a misconfigured VM - a VM that "doesn't give you the clmul instruction for no good reason because the hardware surely has it." Thus, I am wondering if its
09:36:51 born2bake nova configuration?

09:54:51 born2bake stephenfin thank you, I found it before as well... However, I am not really sure which model should I use for my particular case :/

13:11:06 stephenfin gibi: Still investigating that glance bug but I think I'm almost at the bottom of it (tl;dr: it's probably not an issue after all)
13:12:03 stephenfin gibi: question though for you (or anyone else): if an instance fails to build and I then delete it, I see the following warning in my logs
13:12:21 stephenfin instance's host None is down, deleting from database
13:12:35 stephenfin that's from here https://github.com/openstack/nova/blob/master/nova/compute/api.py#L2400-L2401
13:12:38 stephenfin it seems wrong
13:14:21 stephenfin But I can't decide if we should log something special for that (e.g. LOG.info("instance was not scheduled successfully, deleting from database")) or ignore that case entirely (replace the 'else' with 'elif instance.host')
13:14:45 stephenfin lyarwood: it's pretty trivial, but you might have a opinion on that too ^
13:18:20 gibi stephenfin: re: glance related bug, thanks.
13:19:03 gibi stephenfin: regarding the misleading log message for local delete of unscheduled instance. I'm more for adding an elif and a special debug message. that is a small cost but helps troubleshoting
13:21:56 sean-k-mooney stephenfin: today we dont delete instance form the db if they are not scheulded correctly so im configed by the message
13:22:11 sean-k-mooney we put the instance into the error state
13:22:28 stephenfin "so im configed by the message" huh/
13:22:30 stephenfin *?
13:22:38 sean-k-mooney *confused
13:22:49 sean-k-mooney the feeling you feel at reading that
13:22:53 stephenfin how? :D
13:22:54 stephenfin haha
13:23:08 stephenfin sorry, let me restate things
13:23:17 stephenfin we put the instance to error state
