| 17:45:56 | sean-k-mooney | it used to improve perfromance but i stongly doubt it does and it cause issue for windows for example | |
| 17:46:30 | sean-k-mooney | chateaulav: so if you need to change the default toplogy for the emulation usecase i think that is ok | |
| 17:46:33 | chateaulav | definetly, now that ive isolated the area, gonna tweak the topology settings | |
| 18:14:55 | opendevreview | Tobias Urdin proposed openstack/nova master: Cleanup old resize instances dir before resize https://review.opendev.org/c/openstack/nova/+/827865 | |
| 18:22:43 | opendevreview | Dmitrii Shcherbakov proposed openstack/nova-specs master: Late Amendments to the Off-path Backends Spec https://review.opendev.org/c/openstack/nova-specs/+/828177 | |
| 18:27:07 | dmitriis | sean-k-mooney: https://review.opendev.org/c/openstack/nova-specs/+/828177 - uploaded | |
| 18:33:21 | sean-k-mooney | dmitriis: ack am im not really happy with adding allow_remote_managed_ports to the whitelist | |
| 18:33:51 | sean-k-mooney | that feels semanticly incorrect to me | |
| 18:36:33 | sean-k-mooney | dmitriis: the docs issue on the spec repo is not related to your patch by the way | |
| 18:36:35 | dmitriis | sean-k-mooney: the alternative approach I considered was to expose a property on the whitelist which would tell us about whether remote_managed is used or not | |
| 18:36:53 | sean-k-mooney | dmitriis: that i think i coudl accpet yes | |
| 18:37:17 | sean-k-mooney | really the whitelist shoudl not really have awareness of the off-path feature | |
| 18:37:25 | dmitriis | sean-k-mooney: hmm, I felt it was slightly backwards because I am exposing state for somebody else to check but maybe I am wrong | |
| 18:37:28 | sean-k-mooney | a porperty i think woudl be ok | |
| 18:37:43 | dmitriis | I'd have to pass it through both on the whitelist and PciDeviceSpec though | |
| 18:37:58 | dmitriis | because I only know about the use of those tags in the spec object | |
| 18:38:15 | sean-k-mooney | the whitelist shoudl not be doign any validation of those tags | |
| 18:38:23 | sean-k-mooney | only the pci tracker should | |
| 18:39:01 | sean-k-mooney | the whitelist is a POD object | |
| 18:39:10 | sean-k-mooney | it does some basic validation fo the imports | |
| 18:39:48 | sean-k-mooney | but it should not be doing any filtering | |
| 18:41:09 | dmitriis | sean-k-mooney: there's some validation done here https://github.com/openstack/nova/blob/b6fe7521afa8d42febc68f5f79782f7bcc3b568f/nova/compute/manager.py#L1430 | |
| 18:41:16 | dmitriis | which is also very early | |
| 18:41:32 | dmitriis | and I have access to the whitelist here | |
| 18:41:46 | sean-k-mooney | that is in the compute manager | |
| 18:41:55 | sean-k-mooney | so its oke to do it there | |
| 18:42:05 | sean-k-mooney | but really it shoudl not be there either | |
| 18:42:14 | sean-k-mooney | it shoudl be in the resouce tracker or pci manager | |
| 18:42:34 | sean-k-mooney | in https://github.com/openstack/nova/blob/master/nova/pci/manager.py#L38 | |
| 18:43:20 | dmitriis | sean-k-mooney: yeah, this should be set up relatively early as well | |
| 18:43:44 | sean-k-mooney | you shoudl do any validation you need here https://github.com/openstack/nova/blob/master/nova/pci/manager.py#L78-L83 | |
| 18:44:49 | sean-k-mooney | its called as part of _setup_pci_tracker in teh resouce traceker | |
| 18:44:51 | sean-k-mooney | https://github.com/openstack/nova/blob/14bfbaa50ed3c000a691a37afbd20d86f431b3fb/nova/compute/resource_tracker.py#L764-L773 | |
| 18:45:04 | sean-k-mooney | which is invoked as part of _init_compute_node | |
| 18:45:58 | dmitriis | sean-k-mooney: ack. And when it comes to exposing the property, I could populate _has_remote_managed after this line https://github.com/openstack/nova/blob/b6fe7521afa8d42febc68f5f79782f7bcc3b568f/nova/pci/whitelist.py#L51 and expose a property | |
| 18:46:11 | dmitriis | and also expose a property on the spec objects themselves | |
| 18:46:42 | dmitriis | I'd have to do a search over spec objects then and see whether any one of those has a property | |
| 18:46:58 | dmitriis | if that's ok, I'll just do it | |
| 18:47:21 | sean-k-mooney | i think that shoudl be ok | |
| 18:48:01 | sean-k-mooney | it sound cleaner to me overall | |
| 18:48:29 | sean-k-mooney | where/why are you using this by the way | |
| 18:49:02 | dmitriis | sean-k-mooney: this is to make sure remote_managed tags aren't usable on a host where libvirt is too old (doesn't have VPD handling code) | |
| 18:49:25 | sean-k-mooney | right so you dont need this on the spec object or whitelist object | |
| 18:49:34 | sean-k-mooney | that is a check you can do in the libvirt driver at start up | |
| 18:49:54 | sean-k-mooney | you can just loop over the spec objects and check for the tag | |
| 18:50:04 | sean-k-mooney | and check the verisons | |
| 18:50:40 | sean-k-mooney | the device spec will already have the value in the PciDeviceSpec.tags field | |
| 18:50:49 | dmitriis | https://review.opendev.org/c/openstack/nova/+/827839/2/nova/virt/libvirt/driver.py#816 | |
| 18:51:13 | dmitriis | ^ so it's a host-based capability | |
| 18:51:20 | dmitriis | host-dependent * | |
| 18:51:36 | sean-k-mooney | yes | |
| 18:52:15 | sean-k-mooney | that does not need to you modify these data stuctures | |
| 18:52:36 | dmitriis | sean-k-mooney: I don't have access to the host object in those | |
| 18:52:46 | dmitriis | but maybe there's some other way to check the Libvirt version | |
| 18:52:53 | sean-k-mooney | you should not be checkign for them in these | |
| 18:53:03 | sean-k-mooney | dmitriis: you shoudl not be doing https://review.opendev.org/c/openstack/nova/+/827839/2/nova/pci/devspec.py#319 | |
| 18:53:23 | sean-k-mooney | that is not the correct place to raise that excption | |
| 18:53:36 | sean-k-mooney | either the device spec of whitelist shoudl raise that | |
| 18:53:46 | dmitriis | sean-k-mooney: ah, sorry, yes we're moving it elsewhere | |
| 18:54:40 | dmitriis | sean-k-mooney: so maybe in the dev tracker I have access to that info, checking | |
| 18:54:58 | sean-k-mooney | i dont think you do | |
| 18:55:09 | sean-k-mooney | we abstrackt the virt driver info away | |
| 18:55:20 | sean-k-mooney | the pci module is ment ot be virt dirver independent | |
| 18:55:32 | sean-k-mooney | you shoudl be doing this check in the libvirt driver.py | |
| 18:56:19 | sean-k-mooney | you coudl perhaps do it in update_devices_from_hypervisor_resources | |
| 18:56:21 | sean-k-mooney | https://github.com/openstack/nova/blob/b6fe7521afa8d42febc68f5f79782f7bcc3b568f/nova/pci/manager.py#L111 | |
| 18:56:36 | sean-k-mooney | but you would have to modify the device_json which im not sure is the right thing | |
| 18:57:40 | sean-k-mooney | am i need to call it a day | |
| 18:57:56 | sean-k-mooney | dmitriis: can you look at moving the check to the libvirt driver | |
| 18:57:56 | dmitriis | sean-k-mooney: ack, I'll think about how to do it | |
| 18:58:09 | dmitriis | sean-k-mooney: sure | |

| 10:18:23 | kashyap | sean-k-mooney: Do you know if Swift is requirement for vTPM to work? The docs say no: https://docs.openstack.org/nova/latest/admin/emulated-tpm.html | |
| 10:18:39 | kashyap | But the spec mentions "Swift" | |
| 10:19:12 | sean-k-mooney | no its not | |
| 10:19:26 | sean-k-mooney | the storage to swift was never implemented | |
| 10:20:02 | kashyap | Ah-ha, good to know. | |
| 10:20:03 | kashyap | Thank you | |
| 10:20:39 | sean-k-mooney | if i recall correctly that was propsed for shelve which i belive we did not implement | |
| 10:21:30 | sean-k-mooney | kashyap: barbican is needed however for the key management | |
