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

15:43:06	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

07:25:20	gibi	good morning nova

08:46:23	gibi	nice coverage addition!
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?
09:47:05	stephenfin	born2bake: https://docs.openstack.org/nova/latest/admin/configuration/hypervisor-kvm.html#specify-the-cpu-model-of-kvm-guests
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 :/
09:55:17	gibi	stephenfin: hi! Could you confirm / triage the bug https://bugs.launchpad.net/nova/+bug/1736920 I see that the generator -> list conversion is still existing on master but the bug report is pretty old

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
13:23:39	stephenfin	and I see that message when I later attempt to delete the instance
13:23:49	stephenfin	host is unset since the instance failed to schedule
13:24:08	sean-k-mooney	it lands in cell 0 right?
